The foodservice and retail industry has struggled to keep up with the curveballs thrown at it during this pandemic. “Whether reopening dining rooms after extended closures or finding their footing in a world of new omnichannel ordering, quick service restaurant and fast casual managers are grappling with evolving rules and regulations, changing diner preferences, while also welcoming an entirely new workforce,” says Michael Sperber, a global business manager for UL Everclean, a third-party retail food safety and sanitation audit program that helps retail foodservice businesses improve their food safety practices. In a Q&A with Food Safety Tech, Sperber discussed the evolving challenges in the foodservice and retail space over the past 15 months.
Food Safety Tech:On the issue of sanitation and cleanliness, what hurdles do restaurants and grocery stores have in the face of the pandemic and the subsequent labor shortage?
Michael Sperber: Trust in the safety and cleanliness of restaurants and grocery stores is one of the bigger concerns that must be addressed as consumers continue to navigate the pandemic. Consumers now have a higher expectation for their own health and well being, and expect establishments they visit to meet their needs and [doing so] while embracing heightened health and safety protocols.
FST: What steps should they be taking to identify and reduce potential health and safety risks?
Sperber: Amidst new challenges, guidelines and expectations, restaurants continue to have the critical responsibility of offering sanitary eating spaces and food preparation practices that help prevent diners from getting foodborne illnesses. There are several ways that restaurants can do this including:
Leveraging technology to support food safety best practices.
Hand washing monitors help guide employees in proper handwashing techniques.
Internet of Things (IoT) temperature devices can monitor hot and cold food holding and service areas, instantly alerting managers when temperatures fall outside an acceptable range.
Touchless technologies like digital displays in the back of the house reduce transmission risk from employees handling food.
Auditing every location of one branded store can account for differences in employees and managers. Left unverified, the rigor of food safety practices may simply rest on the personal conviction of a single location manager, rendering it completely inconsistent across locations. It is critical that management audit each individual store for compliance with food safety best practices.
iii. Having an emergency plan, and then training for and rehearsing the plan, can help with proper mitigation of the threats of potential contamination.
FST: Discuss the role of employee training in this process, and how organizations should move forward.
Sperber: Training employees in food safety and customer interaction is a vital step in protecting employees and guests from foodborne illnesses. Employees who recently started at a restaurant when it reopened might not be aware of the dangers of foodborne illnesses or basic food safety protocols.
As restaurants reopen, when more and more guests have safety at the top of their mind, they should completely reboot their food safety programs, beginning with basics of safe food handling and foodborne illness. Repetition is a good way to reinforce the importance of food safety, and it may be beneficial to provide multiple training videos, pose questions on food safety during the interview and training process and include food safety on periodic employee reviews. Infractions among employees should result in retraining. This level of repetition communicates the importance of the issue.
A focus on employee training will help lead to a culture of food safety where everyone from the corporate CEO to the manager and janitorial staff feels accountable and can understand the consequences of failure to follow proper protocols.
Futurist Ross Dawson has said that AI and automation will shape the future of work, and it also promises to transform our lives beyond the office. According to the World Economic Forum, when AI, which provides the ability to “enable devices to learn, reason and process information like humans,” is combined with Internet of Things (IoT) devices and systems, it creates AIoT. This super duo has the potential to power smart homes, smart cities, smart industries and even our smartwatches and fitness trackers, a market estimated by Gartner to be worth $87 billion by 2023. More importantly, this “interconnectedness” will change the way we interact with our devices as well as the way we will live and work in the future.
In the restaurant industry, we’re already seeing glimpses of this interconnectedness take shape, and in the past year, we’ve experienced major technological advancements that have transformed every facet of the way food establishments work. Reflecting on those advancements, I want to take a moment to share three areas of AI impact that are bubbling up in the restaurant sector in 2021.
1: AI-powered Intelligent Kitchens
From ghost kitchens to traditional kitchens, the “back of the house” continues to be a prime target for AI and automation. While great progress has been made, in many ways it seems like we’ve only scratched the surface when it comes to how far AI can take today’s restaurants. But every now and then, we hear examples of AI powering the future of our industry. For example, Nala Robotics, Inc. will be opening what it calls “the world’s first state-of-the-art intelligent restaurant” in Naperville, Illinois this year. The company says the AI-based robotic kitchen “can create dishes from any cuisine around the world, using authentic recipes from celebrated chefs”. A press release from Nala Robotics states that its flagship restaurant is taking “the first step in the food service industry with AI-powered service, addressing many of the issues affecting restaurant owners during COVID-19,” and it will “provide consumers an endless variety of cuisine without potential contamination from human contact.” This is the new frontier in intelligent kitchens, and it couldn’t have come at a better time, with the pandemic forcing restaurants to reimagine the way they do business.
2: AI-Driven Labor Shifts.
You can’t talk about AI in the restaurant industry without also having a conversation about the implications for the modern workforce. With AI in restaurant kitchens and beyond, the impact on the labor force is undeniable. By 2024, Gartner predicts “that these technologies will replace almost 69% of the manager’s workload.” But that’s not entirely a bad thing. Instead of manually filling out forms and updating records, managers can turn to AI to automate these and other tedious tasks. “By using AI…they can spend less time managing transactions and can invest more time on learning, performance management and goal setting,” Gartner adds.Managers can also use the extra time to focus more effort on the customer and employee experience. And indeed they should: In a recent Deloitte report, 60% of guests surveyed indicated that a positive experience would influence them to dine at a restaurant more frequently.
Looking at the impact of AI on labor at all levels, from the CEO to the entry-level wage earner, the shift, at its best, will be a transition to more meaningful—and less mundane—work. The evolution of humanity has taken us to the point we’re now at now, with food production and delivery processes becoming increasingly automated. This has been an evolution generations in the making. In an ideal world, everyone at every level of the organization should benefit from this new wave of technology. For example, automation can and should be used to open the door to new training and new opportunities for low-wage earners to learn new skills that elevate career paths, increase income and improve quality of life.
3: AI and Global Supply Chain Transformation
From the farm all the way to the table, AI is now poised to transform the global supply chain. From my perspective, the biggest impact will be around driving sustainability efforts. Restaurant and grocery brands are already beginning to leverage AI to forecast their food supply needs based on customer demand, leading to less over-ordering and less food waste to support sustainability initiatives. One company in this space, FourKites, is creating what it calls “the digital supply chain of the future.” Using real-time visibility and machine learning, FourKites powers and optimizes global supply chains, making them “automated, interconnected and collaborative—spanning transportation, warehouses, stores, trucks and more.”
In addition to predictive planning, more and more brands will start to use AI to create incident risk management models to identify trends and risks in the supply chain to determine whether bad or recalled products are originating from a specific supplier, distributor, or due to an environmental variable.With all of these changes, the need for comprehensive data standards will multiply as suppliers and distributors around the world work together to bring us produce and packaged food from all corners of the globe. Data standards will be critical to traceability and the exchange of critical tracking events and key data elements, and advances in data standards will power the meta-data needed to provide better insight for food quality and regulatory compliance, crisis management, and recalls—at scale.
Research firm Forrester states that, in the end, the greatest impact resulting from an investment in robotics and other technologies that automate operational tasks is improved customer experience (CX). “Most companies believe that investment in AI, automation, and robotics for engagement will decrease operational costs. While this is true, our research shows that the revenue upside from delivering better CX could deliver a greater impact on the bottom line over time,” Forrester states.
As a business engaged in digitizing and transforming supply chain operations, our team couldn’t agree with Forrester more. But we believe it will take striking the right balance between technology and the human touch to not only drive stronger CX, but to also create a world in which AI is implemented for the greater good—a world in which people, processes, business and technology all win.
The COVID-19 pandemic has brought challenges to all industries, and many restaurants have been forced to close their doors permanently. Restaurant owners have struggled due to COVID-19 restrictions that have drastically cut the number of customers they can serve—whether as a result of an indoor dining ban or capacity limits. Those that have been allowed to re-open are being stretched to meet new guidelines to keep guests safe and comfortable while dining. Not only do restaurant owners need to make sure their restaurants are COVID-safe, but they also need to ensure they are providing the quality service and meals their customers have come to know and love. The Internet of Things (IoT) can not only ease the burden of implementing new protocols while also ensuring a clean and safe environment for both employees and patrons, but also help restaurants enhance efficiency.
The following are some points on how the IoT can help restaurants not only survive, but thrive amid the pandemic.
Easy-to-deploy IoT-enabled devices provide several benefits to QSRs, including the monitoring of employee hand washing stations, dishwashing water temperatures, sanitizer solution concentrations and customer bathroom usage frequency to ensure constant compliance with cleanliness standards.
By placing sensors on tables and work lines, restaurant owners can collect valuable data and insights in real time. For example, the sensors can share information about how often tables are being cleaned. This information will help owners trust that tables are being cleaned thoroughly in between each use.
Sensors can also be placed on washbasins to monitor employee hand washing. Sensors on the sinks will not only confirm that employees’ hands have been washed, but they will also share exactly how long employees washed their hands. That way, owners can have peace of mind knowing employees’ hands and restaurant surfaces are properly sanitized before customers sit down to eat. With door sensors monitoring customer bathrooms, store owners can ensure adequate cleaning is allocated based on frequency of usage.
Owners can also have peace of mind knowing their restaurant is rodent free by using IoT monitored sensors. Rodents are especially dangerous to be found lurking in restaurants because they carry diseases and can cause electrical fires. Devices can be placed throughout the restaurant to detect any motion that occurs. When the devices detect a motion, restaurant owners will receive notifications and will be immediately aware of any rodents that may have snuck into the restaurant.
These sensors give restaurant owners a chance to proactively address a rodent issue before it causes damage to their business.
In addition to monitoring sanitation and detecting motion, restaurant owners can leverage the IoT many other ways. For example, IoT devices can be placed on trash bins to alert when they are full and ready to be taken out. They can also be placed near pipes to detect a leak. Sensors can also be placed on all refrigerators to detect temperature. With accurate updates on refrigerators’ temperatures, restaurant owners can easily monitor and ensure that food is stored at the appropriate temperature around the clock—and be immediately alerted if a power issue causes temperatures to change.
IoT devices can offer restaurant owners insights to help them change their operations and behavior for the better. While everyone is eager to go back to “normal” and want our favorite restaurants to re-open as soon as possible, it is important that restaurant owners have the tools needed to reopen safely—and create efficiencies that can help recoup lost income due to COVID-19 restrictions. Restaurant owners looking to receive real-time, accurate data and insights to help run their restaurants more efficiently and ensure a safe and comfortable experience for customers can turn to the IoT to achieve their goals.
Everybody has to eat. That is the mantra of many companies involved in the food and beverage industry. It sounds so simple. Yet, in recent years, especially this one, it is becoming more challenging than we ever thought it could be. Disruptions from the beginning to the end of the food supply chain are making the task of feeding the masses more difficult. The COVID-19 pandemic has made people in all walks of life question the food supply chain. It is being evaluated in new ways with the goal of ensuring that there is food available in not just crisis times but in normal circumstances, too, as the population continues to grow and more disruptions interrupt the supply chain. Climate change is one disruption that is impacting the food and beverage industry and is possibly the biggest threat to overall food sustainability. When people think about climate change they only think about weather events and global warming, but if you look at the definition of “climate,” other issues need to be considered in addition to looking out the window and checking the thermometer.
Global warming, greenhouse gases, carbon emissions, the earth’s normal evolution and consumer behaviors can all contribute to climate change. Everyone talks about limiting greenhouse gases and carbon emissions but is it really happening? Almost every day, some government agency or industrial company announces policy changes touting the drive to 100% sustainable packaging by this year and that year. “Company X announced today that it will use fully-sustainable packaging by 2035.” Fully sustainable packaging; what does that even mean? And 2035, what’s the hurry?! There are other programs in the works, but the question is, are they quick fixes that are really just Band-Aids on a gunshot wound? Are they actually long-term solutions and are they happening fast enough? The adoption of electric vehicles could have a huge impact on our climate but it is just a small piece of the solution for total carbon emission elimination. Water to be used in non-farming consumption is getting harder to come by due to climate change. Land space is eroding and available farm space is decreasing. The process of raising and harvesting livestock is getting more complex and costly, making plant-based substitution options more attractive. But is that really a long-term solution if we are already running out of traditional farming space? Consumers hope that recycling will help combat the problem but it is barely making a dent and their changing food habits impact the climate as well. The earth itself is constantly going through a geological evolution in spite of what we humans do to the planet.
Global warming is accelerating climate change and causing a number of serious issues. The earth’s poles are warming, which is promoting permafrost, causing glaciers to melt and oceans to rise, which is impacting sea levels, irrigation methods and land temperatures that promote erosion. Higher than average temperatures can potentially impact the growing of certain crops in terms of yields and even where they are grown. Climate change is impacting all areas of agriculture, the environment and the total ecosystem. Insect behaviors are evolving and these changes affect crops. The food manufacturing and farming industries have realized that a “new way” needs to be implemented to grow food in environments that can combat these changes.
Sustainability initiatives call for practices that maintain or improve soil conservation and improve the overall health of soil. Two processes, regenerative agriculture and precision agriculture, working in conjunction, may actually provide a long-term solution by combining environmental and farm science with technology. Regenerative agriculture goes beyond soil conservation. It is a process that looks to reverse the effects of climate change. The regenerative process focuses on restoring soil health, solving water issues, reversing carbon cycles, and creating new topsoils and growing environments.
Precision agriculture focuses on increasing the land used for farming as well as increasing the productivity of that land. It utilizes newly available IoT devices like GPS services, guidance systems, mapping tools and variable rate technologies (VRT) to optimize crop yields. These new management systems collect data that transmit valuable metrics to farmers. Every aspect of farming, from planting to harvesting, can benefit from these emerging technologies. The information about the moisture of soil, for example, is sent to a computer, which then identifies signs of health or stress. Based on these signals, farmers can provide water, pesticide or fertilizer in adequate dosages. As a result, precision farming can help conserve resources and produce healthier crops.
Climate-smart agriculture, which is an approach to dealing with the new realities of climate change, is another smart agricultural method. Climate-smart agriculture improves agricultural systems by enhancing sustainability, which leads to improved food security. Food production has struggled to keep up with erratic weather patterns and natural resources have been stretched alarmingly thin, signaling a call for action. With this new approach, crop yields can adapt accordingly and productivity will increase.
The regenerative food system market has drawn a great deal of interest from investment groups. Initial investments have focused on water and soil reconstitution and development. Restoring soil strength reduces water usage and at the same time produces stronger and more available food sources. Underground and hydroponic versions of regenerative agriculture are also emerging.
Advanced technologies like these are making their way into the food, beverage and agriculture industries. Traditional agricultural methods are being replaced with climate-smart methods. Peripheral areas like streamlining the supply chain and optimizing manufacturing operations can receive “sustainable” benefits from these new agri-methods. The good news is that smart agricultural methods are making progress in counteracting climate change and revolutionizing farming worldwide.
Regenerative and precision agriculture are without question the leading processes and philosophies being used today to help all food industries combat climate change and other disruptors to the total food supply chain. These new technologies will continue to efficiently solve farming practices. In addition, there will be rollover benefits to food processors and manufacturers who will now have improved access to data. This will enable better communication, and improved traceability at all levels of the supply chain and throughout operations, distribution and procurement. This data will allow all involved in growing and producing food to communicate better and enable society to adapt to these changes.
The theme of better traceability and more transparency is a theme that will only grow stronger in the food industry. Just last week we heard FDA Deputy Commissioner for Food Policy and Response Frank Yiannas talk about the agency’s recently proposed FSMA rule on food traceability during the 2020 Food Safety Consortium Virtual Conference Series. In a recent Q&A with Food Safety Tech, Mikael Bengtsson, industry & solution strategy director for food & beverage at Infor, explains yet another role that technology can play in helping companies maintain agility during changes that affect the supply chain such as the coronavirus pandemic.
Food Safety Tech: How can food suppliers mitigate the risks of foodborne illness outbreaks under the stress of the COVID-19 pandemic and with limited resources?
Mikael Bengtsson: Food safety must always be a top priority for any food and beverage company. The risks associated with contamination can have a severe impact for public health, brand and company reputation. Safety routines are therefore always of the highest priority. In today’s situation with COVID-19, the stress on safety is further increased. Now, it’s not only about keeping products safe but also keeping employees healthy. One progression and resource that all food suppliers must follow is the FDA [FSMA rules], which require suppliers to be diligent and document their compliance. Especially now, while suppliers are faced with limited resources and additional stress during the pandemic, they must rely on the basics—ensuring masks are worn in and out of the workplace, washing hands for at least 20 seconds prior to touching any food, and remaining six feet apart from co-workers. When it comes to a crisis like COVID, take solace in knowing suppliers can rely on the basics—even when conditions are strained.
This year we have seen many companies having to adapt and change quickly. Demand has shifted between products, ingredients have been in shortage and many employees have had to work from home. Some were better prepared than others in adapting to the new situation. Technology plays a big role when it comes to agility. Regarding food safety, there are many proactive measures to be taken. The industry leaders establish transparency in their supply chain both upstream and downstream, use big data analysis to identify inefficiencies, as well as couple IoT with asset management systems to foresee issues before they happen.
FST: How can technology help suppliers meet the growing consumer demand for transparency in an end-to-end supply chain and improve consumer trust?
Bengtsson: Communication with consumers is changing. It is not only about marketing products, but also to educate and interact with consumers. This requires a different approach. Of course, consumers are loyal to brands, but are also tempted to try something new when grocery shopping. After a new study is published or a new story is written, consumers are likely to shift their shopping preferences.
It is therefore important to build a closer connection with consumers. Companies who have full supply chain visibility, transparency and traceability have detailed stories to tell their consumers. One way they can build these stories is by including QR codes on their packages. The consumer can then easily scan the code and be brought to a website that shows more product details—e.g. who was the farmer, how were the animals cared for and what sustainability efforts were involved. These are all important aspects to build consumer trust. According to researchers at MIT Sloan School of Management, investing in supply chain visibility is the optimal way to gain consumer trust, and can lead to increased sales.
FST: What technologies should suppliers leverage to better collaborate with trading partners and ensure consistent food safety procedures?
Bengtsson: When a food safety problem arises, batches, lots, and shipments need to be identified within minutes. Manufacturers must be able to trace all aspects of products throughout the entire supply chain—with complete visibility at the ingredient level—from farm to table, and everything in-between. An efficient and transparent food supply chain requires extensive collaboration and coordination between stakeholders. New technologies can extend both amount of collaboration possibilities and the impact of those collaborations. In order to maintain a transparent, efficient food supply chain, companies need to invest in modern cloud-based ERP and supply chain systems that incorporate the increased visibility of the Internet of Things (IoT) with data sharing, supplier and customer portals, and direct links between systems—all aimed at facilitating joint awareness and coordinated decision-making. Modern technologies that enable transparency will also have the added benefits of meeting consumer demand for product information, identifying and responding to food safety issues, reducing food waste, and supporting sustainability claims.
Last week we were joined by experts in pest management for Episode 2 of the 2020 Food Safety Consortium Virtual Conference Series. Although pest management may not be seen as the most exciting topic, all food plants are required to have an integrated pest management program. In addition, the digital transformation fast-tracked by COVID-19 is also driving innovation in the remote monitoring of pests.
Barney Debnam, global agriculture strategy lead at Microsoft kicked off the conversation with some key themes driving change within the global food system, which have also been accelerated by COVID: Geopolitical forces, consumerization, democratized biology, sustainability, shifting economics and food security. As technology continues to evolve and is adopted at a faster pace (think artificial intelligence and how accessible it is now), businesses will be able to transform their outcomes by becoming more predictive. The key technology enablers in the process include:
Internet of Things and edge computing
Artificial intelligence and cognitive computing
The most significant benefit of implementing technology such as remote monitoring into an IPM program is its ability to provide visibility and the data to back up what is happening in a facility.

Since the early 20th century, food safety has been a paramount concern for consumers in the United States. Upton Sinclair’s The Jungle, which painted a bleak, brutal, and downright disgusting picture of turn-of-the-century food processing facilities led to the creation of some of the country’s first food safety laws. Today, federal agencies and statutes make up a comprehensive food safety system to ensure that the growth, distribution and consumption of foods are safe from start to finish.
While food safety has significantly improved in the century since Sinclair’s time, stories of major outbreaks of foodborne illnesses continue to pop up across the country. Over the past few years, a significant number of outbreaks as a result of pathogens have made the headlines. To mitigate the threat of public health crises and ensure food production and distribution is safe and secure, companies must rely on modern technology to trace the movement of food across the entire supply chain.
How Technology Is Changing the Food Industry
Technology is a powerful, innovative force that has changed the way even well established companies must do business in order to stay relevant. From easier access to nutritional information to digital solutions that make food manufacturing and distribution more efficient, greater consumer awareness driven by technology empowers consumers to make decisions that can greatly affect the food industry’s bottom line.
Technology-driven accountability is playing one outsized role in allowing consumers to make better choices about the foods they consume and purchase. Social media and smartphone apps connect consumers to a wealth of resources concerning the harmful effects of certain ingredients in their food, the source of products, and how particular items are made and produced. In 2015, for example, The Campbell Soup Company removed 13 ingredients from its traditional soup recipes as a result of a greater public demand to understand food sources. Neither food giants nor small producers should expect to remain immune from greater public scrutiny over food health and safety.
Nutritional research is also helping change the conversation around food, granting nutritionists and consumers alike greater access to food-related data. Through easily accessible scholarly journals, apps that provide real-time nutrition information, and meal tracking apps that help users log and understand what they’re eating, consumers can gain a better understanding of nutrition to make more informed choices about their daily food intake. Researchers can also use food-tracking apps to make discoveries about consumer behavior and foods that are eaten.
Technology is also being used to tackle food waste, one of the most pervasive problems facing the food industry. One-third of the total amount of food produced globally, amounting to nearly $1.2 trillion, goes to waste every year. Solving this pervasive crisis has become an industry imperative that is being tackled through a variety of innovative technologies to improve shelf-life, dynamically adjust pricing based on sell-by dates, and allow restaurants to automatically monitor their daily waste.
In the food manufacturing sector, digitally-connected supply chain systems are providing greater visibility into the production of foods and beverages. Supplier management technology delivers data that can be used to optimize processes and improve quality in real-time, making it easy to adjust to consumer demands, respond to logistics challenges, and boost government compliance. The enhanced operational benefits offered through improved supply chain visibility allows manufacturers to produce products faster, safer, and with greater transparency.
Online ordering has also ushered in a new era of food industry behavior. The growing assortment of online ordering apps has just given the consumer more control over quickly ordering their next meal. The trend in online ordering has also allowed restaurants to experiment with new business models like virtual kitchens that offer menus that are only available online.
IoT: The Future of Food Safety
From the farm to the carryout bag, the impact of technology on the greater food industry is already evident in daily practice. Through enhanced access to data, food producers can run an efficient supply chain that reduces waste, boosts productivity, and meets consumer demand in real-time. Using a variety of online resources, consumers are empowered to quickly make well-informed food purchases that are healthier, more convenient and more sustainable than ever before.
The Internet-of-Things (IoT) adds a layer of technology to the food manufacturing process to ensure greater food safety. A broad series of networked sensors, monitors, and other Internet-connected devices, IoT technology can oversee the entire food manufacturing and distribution process from the warehouse to the point of sale. Boosting transparency across the board, intelligent sensors and cameras can transform any food manufacturing operation into a highly visible, data-backed process that allows for better decision-making and improved real-time knowledge.
While IoT technology is a powerful tool that can improve the efficiency of restaurants and provide enhanced customer experiences, some of its greatest potential lies in its ability to safely monitor food preparation and production. Live data from IoT devices makes it possible to closely monitor food safety data points, allowing manufacturers and restaurants to reduce the risks of foodborne illness outbreaks through enhanced data collection and automated reporting.
Domino’s Pizza, for instance, embraced IoT technology to enhance management processes and monitor the food safety of its products. In the past, restaurants have relied on workers to record food temperatures, a practice that was occasionally overlooked and could lead to issues with health inspectors. Using IoT devices for real-time temperature monitoring, Domino’s automatically records and displays temperature levels of a store’s production, refrigeration, and exhaust systems, allowing employees to view conditions from a live dashboard.
In addition to boosting food safety, the comprehensive monitoring offered by IoT technology can help food companies reduce waste, keep more effective records, and analyze more data for improved operations.
IoT isn’t just a safe solution for improving food safety: It’s a smart solution.
Blockchain: The Future of Food Traceability
The ubiquity of QR codes has made it easy for consumers to quickly gain access to information by scanning an image with their smartphone. From accessing product manuals to downloading songs, QR codes make it simple to provide detailed and relevant content to users in a timely manner.
Blockchain technology provides a powerful opportunity to provide consumers with similar information about food safety. Able to instantaneously trace the lifecycle of food products, blockchain can report a food’s every point of contact throughout its journey from farm to table. By scanning a QR code, for instance, users can quickly access relevant information about a food product’s source, such as an animal’s health, and welfare. Shoppers at Carrefour, Europe’s largest retailer, area already using blockchain traceability to track the stage of production of free-range chickens across France.
Walmart piloted a blockchain implementation by tracing a package of sliced mangoes across every destination until it hit store shelves, from its origin at a farm in Mexico to intermittent stops at a hot-water treatment plant, U.S processing plant, and cold storage facility. Real-time product tracing can be conducted in just two seconds, enabling Walmart and other vendors to provide consumers with access to food safety information that could easily be updated should an outbreak or contamination occur.
Blockchain’s inherent transparency not only makes it possible to identify the safety of food production; it also enhances the safety of the business of food production itself. Because blockchain is based upon an immutable, anonymous ledger, record keeping and accounting can be made more secure and less prone to human error. Payments to farmers and other food suppliers can also become more transparent and equitable.
The High Tech Future of Food
Unlike the days of Sinclair’s The Jungle, food transparency is the name of today’s game. As consumers continue to demand greater access to better food on-demand, food producers must continue to find innovative ways of providing safe, healthy, and ethical solutions.
IoT devices and blockchain present food manufacturers with powerful technological solutions to solve complex problems. Brands choosing to rely on these innovations, such as Domino’s and Walmart, are helping ensure that food is produced, prepared and distributed with a foremost emphasis on health and safety. As these technologies continue to become more intelligent, well-connected, and embraced by leading food producers, consumers should rest assured that they’ll always be able to know exactly what they’re eating, where it’s from, and whether it’s safe.
Foodborne pathogens, such as bacteria and parasites in consumable goods, can result in illnesses and deaths, wreaking havoc on residents of states and countries. The companies at fault often face severe damage to their reputation as people fear that continuing to do business with a brand is not safe. Moreover, if the affected enterprises do not take decisive steps to prevent the problem from happening again, they may receive substantial fines or closure orders.
Statistics from the U.S. federal government indicate that there are approximately 48 million cases of foodborne illnesses in the American food supply each year. Fortunately, there are proven steps that production plant managers can take to minimize the risk of foodborne pathogens. Being familiar with the preventative measures, and taking steps to implement them prevents catastrophes.
Engage with Suppliers about Their Efforts to Kill or Reduce Foodborne Pathogens
Foodborne pathogens can enter a production plant on items like fresh produce received from farm suppliers. Agricultural professionals commonly use chlorine to decontaminate goods before shipping them. However, researchers used a chlorine solution on spinach leaves to assess its effectiveness in killing common types of bacteria. The team discovered that, even after chlorine exposure, some bacteria remained viable but undetectable by industrial methods.
Foodborne pathogens can originate at farms for other reasons, too. Failing to take the proper precautions during animal slaughter can introduce contaminants into meats that end up in food production facilities. Water impurities can also pose dangers.
All production plants should regularly communicate with suppliers about the actions they take against foodborne pathogens. Food safety is a collective effort. Practicing it means following all current guidance, plus updating methods if new research justifies doing so. If suppliers resist doing what’s in their power to stop foodborne pathogens, they must realize they’re at risk for severing profitable relationships with production plants that need raw goods.
Consider Using Sensors to Maintain Safe Conditions
The Internet of Things (IoT) encompasses a massive assortment of connected products that benefit industries and consumers alike. One practical solution to enhance food safety in a production plant involves installing smart sensors that detect characteristics that humans may miss.
For example, the USDA published a temperature safety chart that explains what to do with food after a power outage. Most items that people typically keep in refrigerators become dangerous to eat if kept above 40o F for more than two hours.
Food production plants typically have resources like backup power to assist if outages occur. But, imagine a cooler that appears to work as expected but has an internal malfunction that keeps the contents at incorrect temperatures. IoT sensors can help production plant staff members become immediately aware of such issues. Without that kind of information, they risk sending spoiled food into the marketplace and getting people sick.
Researchers also developed a sensor-equipped device that detects the effectiveness of hand washing efforts. In a pilot program involving 20 locations, contamination rates decreased by 60% over a month. Most restrooms at food preparation facilities remind people to wash their hands before returning to work. What if a person takes that action, but not thoroughly enough? Specialty sensors could reduce that chance.
Install Germicidal Ultraviolet Lights
With much of the world on lockdown due to the COVID-19 pandemic, many people want to know if germicidal ultraviolet lights could kill the novel coronavirus. Researchers lack enough information to answer that question definitively. They do know, however, that germicidal ultraviolet lights kill up to 99.99% of bacteria and pathogens.
Plus, these lights are particularly useful in food production because they get the job done without harsh chemicals that could make products unsafe. Ultraviolet lights can damage the skin and eyes, so you must only run them when there are no humans in the room. However, it’s immediately safe to enter the environment after switching the lights off.
These specialized light sources do not eliminate the need for other food safety measures. Think about implementing them as another safeguard against adverse consequences.
Teach Workers about Safe Practices
Food contamination risks exist at numerous points along the supply chain. Mishandling is a major culprit that could make several parties partially responsible for a foodborne pathogen problem. For example, if a person does not wear the proper gear when handling food or stores items intended for raw consumption in places where meat juices touch them, either of those things and many others could cause issues with foodborne pathogens.
As you inform employees about which procedures to take to manage the risks, emphasize that everyone has an essential role to play in keeping products free from contaminants. If workers make ready-to-eat foods, such as packaged sandwiches, ensure they understand how to avoid the cross-contamination that happens when reusing cutting boards or utensils without washing them first.
The FDA requires domestic and foreign food facilities to analyze and mitigate risks. Employee training is not the sole aspect of staying in compliance, but it’s a major component. If a person makes a mistake due to improper or nonexistent training, that blunder could have significant financial ramifications for a food production facility.
Widely cited statistics indicate that food recall costs average more than $10 million, which is a staggering figure in itself. It doesn’t include litigation costs incurred when affected individuals and their loved ones sue companies, or the expenses associated with efforts to rejuvenate a brand and restore consumer confidence after people decide to take their business elsewhere.
Ensuring that workers receive the necessary training may be especially tricky if a human resources professional hires a large batch of temporary employees to assist with rising seasonal demands. If a higher-up tells them that time is of the essence and the new workers must be ready to assume their roles on the factory floor as soon as possible, training may get overlooked. When that happens, the outcomes could be devastating. Efficiency should never get prioritized over safety.
Stay Abreast of Emerging Risks
Besides doing your part to curb well-known threats that could introduce foodborne pathogens, spend time learning about new problems that you may not have dealt with before.
For example, scientists have not confirmed the origin of COVID-19. However, since early evidence suggested live animal sales and consumption may have played key roles, Chinese officials cracked down on the wildlife trade and imposed new restrictions on what was largely an unregulated sector cloaked in secrecy.
Much remains unknown about COVID-19, and it’s but one virus for food producers to stay aware of and track as developments occur. The ongoing pandemic is a sobering reminder not to blame specific groups or ethnicities, and to avoid jumping to hasty conclusions. It’s good practice to dedicate yourself to learning about any production risks that could introduce foodborne pathogens. Read reputable sources, and don’t make unfounded assumptions.
A Collective and Constant Effort
There is no single way to combat all sources of foodborne pathogens. Instead, anyone involved in food production or supply must work diligently together and know that their obligation to prevent issues never ceases.
To get to the restaurant table, food must travel great lengths to preserve that farm fresh quality and in many cases, IoT-enabled sensors are being used to do this. This is especially important as the World Health Organization estimates that one in 10 people fall ill every year from eating contaminated food.
When we think of our favorite dish, we often associate it with delicious flavors, pleasant scents and even memories of a night out with friends. What we likely don’t consider is technology, something that’s critical in ensuring the meal on our plate is safe to consume. Technology plays an essential role in guaranteeing that restaurants are serving fresh food to customers. From identifying operational deficiencies to protecting the overall brand of an organization, there are certain measures restaurants are taking—whether local or country-wide chains—to ensure food quality remains a top priority.
Restaurants are perhaps held to an even higher standard than your local supermarket when it comes to the quality of food on the table. Therefore, it’s imperative that perishables are cared for properly throughout the entirety of the food supply chain and that starts well before the food ever enters the restaurant’s front door. With long-range, low-power wireless IoT technology, farmers can get insights into a number of variables that may impact the growth of their crops. Armed with that knowledge, they can make real-time decisions to optimize crop growth and ultimately produce a greater yield. For example, farmers today can set up a series of sensors throughout their farm to measure real-time soil conditions, including humidity and pH levels. If they notice an especially high pH, for example, they can immediately remedy the situation and provide the crop with the proper nutrients or conditions it needs to grow.
For food safely to arrive at restaurants, it must be kept in a controlled environment during its journey from the farm or warehouse, and carefully monitored during that time. The temperature of refrigerated shipping units or storage facilities is an incredibly important factor, as bacteria growth can increase even by simply opening the refrigerator door or with a slight temperature shift, and employees are often tasked with managing this. With large facilities comes increased labor for employees, which can lead to inefficient temperature monitoring. To eliminate food waste and contamination, IoT sensors deployed throughout facilities can eliminate human error, and deliver more consistent monitoring, via real-time updates when temperatures enter unsafe territories.
Numerous international food handling and food safety laws have been implemented to reduce the risk of foodborne illness resulting from bacterial growth. A major component of most “farm-to-fork” regulations is the ability to track, report and maintain appropriate temperature conditions inside refrigeration and freezer units throughout the entire cold chain—including when the food finally makes it the restaurant.
This is a universal priority for restaurants around the world, including Hattie B’s Hot Chicken, a southern-style food chain, which started in Nashville and now has locations nationwide. To successfully do this, the restaurant turned to technology. They used a supplier of wireless connectivity solutions with integrated long range, low power technology for temperature monitoring sensors. The sensors, which are capable of penetrating stainless steel doors and concrete walls, can monitor temperatures in refrigerators and freezers. This is essential, as the technology eliminates possible human error in manually checking temps and other food safety procedures. In instances where refrigerator temperatures shift out of range, the technology remotely notifies restaurant managers in real-time, allowing them to act quickly, ensuring their perishables remain fresh and safe for customers at all times.
Food waste in restaurants is closely tied to food safety. In the United States alone, food waste is estimated to be between 30–40% of the food supply, according to the USDA. In the restaurant industry in particular, human error is one of the most notable reasons for food waste. To eliminate the human error when handling food and monitoring storage, an IoT solution provider for the industrial, smart city and smart energy segments, integrated long-range low power technology into smart refrigeration solutions for restaurant applications. This IoT solution is designed for humidity and temperature monitoring, delivering real-time updates to managers to ensure the shelf life of food is maximized and it remains safe to consume, ultimately leading to a decrease in food waste.
From farm to table, technology plays an essential role in ensuring restaurants are delivering the highest quality of fresh, safe food. It allows organizations to identify operational deficiencies and reduce overall food safety risk, which is imperative when maintaining a strong business in a competitive industry.
