Using Internet of Things (IoT)-based systems to automate temperature monitoring in refrigerators and freezers offers several benefits to restaurants. Following we look at how automated temperature monitoring works and how to get started with IoT.

How it Works: Automated Temperature Monitoring in Action

IoT-based systems use sensors to continuously monitor temperatures in refrigerators and freezers. These sensors are mounted inside the cold storage units in the warmest part of the unit, typically near the door or opening. The sensors collect temperature readings periodically and transmit the data to the cloud. As the data is recorded, the system can detect and report any anomalies.

If the conditions inside a refrigerator or freezer fall outside of predetermined thresholds, managers and staff can be notified (via text, email, or in-store apps) so they can take quick corrective actions outlined in their risk mitigation plans. In addition, the data that is recorded and stored can be analyzed to help identify trends that can be used to inform maintenance schedules and make operations more efficient. For example, the data may show how many years (on average) a refrigerator will last before it fails, so an organization can plan to buy replacement units before a failure occurs.

Benefits of Automated Temperature Monitoring

The positive impacts of automated temperature monitoring, enabled by IoT, are often realized in four key areas:

Food Safety. Maintaining a controlled environment in refrigerators, freezers, and other food storage areas reduces the risk of spoilage. By automating the monitoring process, organizations can keep a continuous watch on cold storage units and alert staff if temperatures rise above predetermined thresholds, allowing them to take immediate corrective action based on their risk mitigation processes. This is particularly beneficial in situations where a refrigerator door might be kept open too long, a freezer door is not entirely shut, or during a power outage.

Regulatory compliance. Regulatory agencies require reporting of food safety compliance. Typically, this is a human-driven process, with manual checks of thermometers and handwritten logs. IoT technologies that automatically monitor and record temperatures provide easy reporting of temperature levels over time. This streamlined process makes it much faster—and easier—to demonstrate compliance.

Efficiency. Automated temperature monitoring can make back-of-house restaurant processes more efficient by eliminating the manual “check and record” processes mentioned above. This frees up staff time to focus on other important tasks, such as serving customers.

Sustainability. By reducing food waste due to spoilage, automated temperature monitoring supports sustainability goals.

How to Get Started

With a wide range of IoT devices and systems available, selecting the right one can be overwhelming. How can you get started? First, identify your organization’s overall goals in incorporating the new technologies, and then review those high-level goals as you investigate options. Here are some criteria to consider:

Device selection: When selecting IoT devices, one size does not fit all. Different devices deliver varying degrees of functionality. Some devices support a single use case, while others have multiple sensors to enable diverse use cases for scalability. Another consideration is battery life. Seek devices that offer extended battery life by leveraging user-replaceable batteries designed for low temperature environments. Other features to look for include use of food-grade plastics and support for firmware updates over the air (FUOTA).

Wireless technology: To effectively penetrate dense refrigerator materials (typically metal), most food service operators are using the open standard, LoRaWAN due to its ability to penetrate walls and maximize battery life.

Data caching: In the event of an interruption in connectivity, you must know what the refrigerator or freezer temperatures were during the outage. Some devices and gateways can cache data and resend as soon as they reconnect, while others cannot. Temperature data caching is critical for applications related to food safety, so be sure to ask for this during the research and evaluation process.

Deployment capabilities: Deployments are complex, and a provider that can navigate deployments at scale is vital. It is important to look at each provider’s technology offerings, installation, and deployment capabilities.

There are many benefits to using IoT to deliver automated temperature monitoring, and these benefits extend beyond food safety to sustainability and improved efficiency. They key is to identify the right devices for your organization’s specific needs.

Level Up Safety with Food Packaging Automation Technologies

By Emily Newton

Food packaging automation technologies can increase productivity and improve food safety. We highlight three key packaging technologies worth investigating.

1. Image-Based Sensors

Foreign objects in packaged foods are a key cause of recalls and can lead to both physical harm and reputational damage. Some companies are incorporating food packaging automation solutions that rely on cameras to detect foreign objects before products leave production facilities.

In one example, researchers from Ritsumeikan University in Japan used a tactile-based image sensor mounted on a high-resolution camera to look for hard objects, including shell and bone fragments, within soft foods. This technology found sub-millimeter foreign bodies and required only 10 seconds to scan a piece of food.

Some sensors can sort food, such as rice, based on appearance. If the rice does not meet specifications—or if a contaminant is detected—the device emits coordinated air puffs to blow the subpar product or contaminant into a reject bin.

Image-based sensors do not replace people from inspection processes. The goal is to boost quality control by combining advanced technology with human oversight. This allows food packaging plants to reduce the risk of unsafe consumables reaching the market.

2. Robots

Robots have been game-changers in food packaging automation. Statistics show that Chinese food and beverage industry clients purchased an estimated $196 million in robotic technology in 2022, with companies from the U.S. investing roughly $160 million in these technologies. These numbers have climbed since 2020, suggesting more company leaders are embracing robotics for their operations.

Companies that don’t have enough employees to handle the workload can compromise safety if they give workers more responsibilities than they can handle or force them to work too quickly. However, robots can ease some of that strain. One robotic top loader for wrapped food products processes up to 120 products per minute, depending on the type.

In another case, a food packaging plant had only 30 employees but needed to switch to 24/7 production to meet customer demand. Adding three collaborative robots, or cobots, to the workflow made it safe for the small team to ramp up activities without getting overwhelmed.

It can take food packaging plant leaders time and effort to figure out the best ways to bring robots into a facility. It helps to determine which tasks are most prone to errors and likely to result in injury. Alternatively, managers can ask line workers which duties feel the most cumbersome or dangerous.

Many employees are initially hesitant about working with cobots. They feel more positive and comfortable about these changes when they realize the machines supplement their work rather than replace it.

3. Upcycled Food Packaging

Food packaging automation has benefits that extend beyond the production environment. Singapore-based Alterpack uses automated equipment to turn spent grain into takeout containers and other types of packaging. The packaging is microwave and freezer-safe, and people can toss it into their compost heaps after use.

The company’s goal is to help reduce dependence on single-use plastic packaging. The process requires cleaning raw materials, mixing a specialty formula and molding it into desired shapes. Automation keeps these steps safe and consistent.

Other types of automation specific to food packaging focus on consumer safety. One project from the Fraunhofer Institute for Process Engineering and Packaging involved embedding packages of meat and fish with chemosensors to measure freshness. The sensors change color automatically when exposed to volatile compounds that indicate product spoilage. The visual indicator makes it easy for consumers, grocery store workers, and others to see when food is no longer safe to sell or eat.

Elsewhere, a team of researchers from Harvard University and Singapore’s Nanyang Technological University made a type of smart food packaging primarily constructed from corn protein. The packaging contains innovative nanoscale mesh fibers and natural antimicrobial compounds programmed to sense common kinds of bacteria in food. When the bacteria are detected, the packaging automatically sprays out tiny amounts of antimicrobials to keep food fresher and safe to eat for longer.

These are just some of the forward-thinking ways food packaging designers can incorporate automation into their production process. Options like these will likely become more widespread as more people experiment with what’s possible, spurring progress in food safety, productivity and waste reduction.

Does Your Ghost Kitchen Have Skeletons in Its Closets?

By Dallas Henderson

At the beginning of the pandemic, restaurants were hit hard. Fine dining sales dropped by more than 90%, casual dining was down 75%, and fast casual decreased by 65%. Nearly two years later, the restaurant industry is still reeling. Most restaurants experienced huge financial losses, and many couldn’t survive. Our industry continues to deal with supply chain disruptions, rising prices, skyrocketing rent, labor shortages and other major challenges. To make matters worse, new COVID variants and surging cases has consumers on their couches watching Netflix and avoiding dining out.

Back in March 2020, delivery orders surged by 67%, and now 60% of American consumers order takeout or delivery at least once a week. Online ordering is growing 300% faster than in-house dining. And operators are discovering a colossal opportunity: Ghost kitchens.

Ghost kitchens allow operators to utilize commercial kitchens without the overhead (and expense) of a full restaurant space and staff. They focus solely on prepping and cooking “to go” orders, and don’t have the option of onsite dining.

While the business model may have shifted, ghost kitchens still need to prioritize food safety and quality, just as traditional restaurant kitchens do. As such, they should:

Embrace digital tools. Tech tools make food safety and quality assurance much easier to manage. Use digital tools to elevate food safety checklists and audits, track ingredient lists, manage allergen information, spot trends, etc. These solutions can help staff manage food safety processes, quickly, easily, efficiently and accurately.
Use sensors. Install digital sensors to check equipment. For instance, these tools can alert the team if a refrigerator or freezer door is accidentally left open, or if temperatures drop below a certain level. Digital thermometers are also essential to check food temps and to ensure foods are cooked properly.
Use tech tools for ongoing training. All workers must be trained in food safety, not just upon hiring, but throughout their tenure. Use tech tools to provide regular training and safety reminders. Send small “chunks” of information right to employees’ phones and provide online resources so they have valuable information right at their fingertips. Communicate regularly with employees, sending updates on COVID protocols and other important safety information.
Be transparent. Food safety practices used to happen “behind the scenes.” Restaurant guests just assumed that employees were taking proper safety precautions. Today, though, everyone’s demanding safer practices, and they want to see staff wearing masks, more frequent sanitation of high touch surfaces, proper social distancing, etc. Since ghost kitchens are a virtual business, you’ll have to proactively spotlight the safety and quality protocols you follow to reassure customers (and prospects) that you take safety very seriously.
Use social media to spotlight your safe practices. Traditional restaurants display health inspection letter grades and reports in their dining areas or storefront windows. Since ghost kitchens don’t have storefronts or dining areas, you’ll need to find new ways to spotlight your commitment to safety. Post information on your website and social media platforms about your meticulous attention to safety and quality to make customers feel safe ordering from you.
Audit differently. Pre-COVID, restaurants and other commercial kitchens had third-party auditors come onsite occasionally to inspect their facilities. Now, food businesses—including ghost kitchens—must audit differently, especially when travel restrictions and other COVID-related disruptions make in-person auditing unfeasible. Use a combination of regular self-assessments, remote auditing, and onsite inspections (when possible) to ensure safety protocols are being followed, the facilities are spotless, equipment is working properly, etc. Previously, in-person audits were often viewed as punitive, with the Big, Bad Auditor coming onsite to point out a company’s mistakes. Now, teams are more engaged and invested in the process, making these inspections more collaborative and cooperative. Also, operators are conducting more frequent remote audits and self-inspections, rather than annual or bi-annual onsite audits, which is a great way to identify (and fix) infractions before they become liabilities.
Prioritize food safety. Even though your business model may have changed from a traditional restaurant to a ghost kitchen, your focus on food safety must remain top-of-mind. Follow food safety protocols: Cook to proper temps, store foods properly, don’t cross-contaminate, accommodate food allergies, etc. In addition, be sure everyone on your team follows COVID protocols: Frequent sanitation of high-touch areas, frequent hand washing, social distancing, masking and not working when ill.
Only work with vendors that prioritize food safety. Be aware of your vendors’ food safety policies. Only work with suppliers that adhere to the strictest safety and quality standards, and make sure that they’re properly certified. New software solutions allow you to easily manage and track supplier certifications.
Accommodate food-allergic guests. Train your staff about food allergies. Have a knowledgeable manager carefully oversee meal prep (and answer questions) for food-allergic customers. Designate an allergy-friendly prep area where foods can be prepared without contamination risk. Use clean and sanitized utensils to prepare allergy-friendly foods. Mark food-allergic guests’ meals with a frill pick or special colored container. Put allergy-friendly meals in separate containers for delivery so there’s no risk of cross-contamination.
Deliver foods safely. Delivery-only concepts must ensure that foods are kept safe from their kitchen to their customers’ homes. Your drivers should have equipment to keep foods at proper temperatures—hot foods hot, cold foods cold—during delivery. Drivers should also sanitize their hands frequently, including after they touch doorknobs, doorbells, money, pens, etc.

Ghost kitchens are an exciting new chapter for our industry. It has been wonderful to see savvy operators pivot to this new business model to accommodate increased consumer demand for “to go” meal options. While ghost kitchens operate without the overhead and infrastructure of traditional restaurants, they still must prioritize food safety every day, for every shift and every meal.

How to Use the IoT to Keep Your Restaurant Clean and Safe

By Hussain Suleman

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.

Monitoring Cleaning

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.

Rodent Detection

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.

Routine Monitoring

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.

How to Improve Food Processing Efficiency

By Emily Newton

For food processors, efficiency can be a major asset. Cutting production times and improving kitchen throughput is one of the best ways to reduce costs and boost profits. In recent years, new management strategies and a range of technologies—like Industry 4.0—has transformed how business owners manage their facilities, including food processing plants. This means there is a range of new, efficiency-improving tools available for businesses that want to streamline plant processes and better manage their operations. The strategies and investments are some of the best possible ways for food processors to improve their plant’s efficiency.

1. Take Advantage of Industry 4.0 Technology

Over the past few years, the digital transformation of industries has resulted in a wide range of products, platforms and devices that can help streamline facility operations and workflows.

Industrial Internet of Things (IIoT) sensors, for example, are Internet-connected sensors that collect a wide range of real-time data from site processes. This data can help food processors improve their bottom lines in a few different ways—like by providing better data on food safety or providing real-time quality control.

For example, IIoT sensors can be used to keep an eye on equipment performance and machine health. An air pressure sensor, installed at the right place in an HVAC duct, can provide valuable notice on blockages and damaged filters. When air pressure drops dramatically, it is typically a sign of some kind of blockage in the HVAC system. This advanced notice can help you fix the HVAC system quicker, potentially saving money and preventing dust or other contaminants from reducing facility air quality.

These IIoT systems also make it much easier to collect information about a facility. This information can help unlock insights about workflows, processes and site layouts, allowing changes that make a facility even more efficient.

For example, you may be able to gather hard data on how an individual product or product line influences machine timing—or how production of a particular item may slow down throughput or make workers less efficient. This information can help you adjust site processes, simplifying the workflow for products that put more strain on your facility, or cutting those products entirely in favor of simpler-to-produce items.

2. Use Efficient Equipment and Materials

Equipment choice can have a major impact on the overall efficiency of a facility. Even small choices—like the lightbulbs used or HVAC filters installed—can add up over time, reducing a facility’s energy bill and contributing to a more comfortable working environment.

Filter choice, for example, is especially important at plants that process a significant amount of wastewater or similar fluids. Good filtration is necessary to remove dangerous chemicals and contaminants from wastewater, but not all filter materials are made equal. Some perform much better than others—and this cost efficiency can have a major impact on a long enough timescale.

EPDM, for example, is an FDA-approved food-grade rubber and a common gasket material for equipment used in industrial kitchens and other food processing plants. It is also a common filter material. However, EPDM filters have a tendency to swell and suffer from performance issues over time. They may require more regular maintenance, which could negatively impact the productivity of a filtration system. PTFE membranes, in contrast, don’t have the same drawbacks.

Making simple adjustments—finding the right kind of filter or LED bulb— can help reduce maintenance costs and improve facility energy efficiency. Often, these changes can happen without major adjustments to the underlying equipment or workflows that keep the factory moving. These upgrades are a great place to start if you want to see how smaller tweaks and adjustments impact facility efficiency before moving on to more major changes.

3. Find Ways to Conserve Water

Similarly, food processing plants can save significantly by finding ways to reduce the amount of water they consume. Water is often seen as a free commodity in food processing plants—but consumption of water can become a significant expense at scale. Equipment, practices and machinery that help reduce water usage can be a way to cut down on costs while making the plant a little more eco-friendly.

Simple changes can make a notable difference without requiring new equipment. For example, some plants may be able to begin cleaning floors and equipment with sweeping or mopping rather than hoses. Mobile sweepers can cover large areas, like parking lots, that can’t be swept with manual labor alone. In one example, Bartter Industries, a New South Wales-based poultry product manufacturer, was able to reduce its water consumption by 10,000 liters a day (approximately 2,640 gallons) by switching from hosing to mopping and sweeping.

More extensive equipment and facility upgrades can yield more significant results.

Increasing the efficiency of water usage may also help future-proof a plant. Industrial water and sewage rates have risen significantly over the past two decades. Water insecurity and droughts may drive these prices higher in the near future.

Many major food production companies—including Pepsi-Cola and Coca-Cola—are already in the process of investing major amounts of money in water reuse and conservation technology.

Adopting similar technology and practices at your facility can provide a valuable competitive advantage now and help in the future when water reuse and stringent water conservation policies are more common.

4. Upgrade Your Maintenance Plan

Scheduled maintenance is one of the most commonly used maintenance approaches. Having such a plan in place can help reduce sudden, unexpected machine failure—helping avoid major downtime and reducing spending on replacement parts for facility machinery.

There are, however, major limitations to the scheduled maintenance model. Every time a machine is opened for maintenance, technicians may unintentionally expose sensitive electronics and internal components to dust, oil, fluids and other contaminants. Regular checks also won’t catch everything. If an issue arises and causes machine failure between scheduled checks, workers and supervisors will have no advanced notice of that machine’s failure, potentially leading to damage or injury.

New Industry 4.0 tech, however, means you can do even better than scheduled maintenance. Predictive maintenance is a maintenance approach that uses data collected from IIoT devices to improve maintenance checks and provide advanced notice on potential failure.

With this approach, IIoT sensors installed in and around machinery capture real-time data on how individual machines are behaving. If one begins to function unusually—exceeding safe temperature ranges, vibrating excessively or emitting strange sounds—the sensors can capture this behavior and alert a supervisor.

This maintenance method can help any facility cut down on maintenance checks and reduce the risk of sudden downtime due to damaged equipment.

Improve Food Processing Efficiency with These Strategies

Improvements to efficiency can be a major advantage for food processors. These strategies and investments are some of the best ways to improve a plant’s efficiency. Simple adjustments to materials, equipment, and workflows—or more serious investments in technology like predictive maintenance platforms—can make a significant difference in a facility’s productivity and resource usage.

How to Prevent Foodborne Pathogens in Your Production Plant

By Megan Ray Nichols

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 40^o 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.

How Technology Simplifies Food Safety Operations

By Roelof Koopmans

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.

Increasing Food Safety and Spoilage Prevention in the IoT Era

By Marc Pégulu

According to the Food and Agriculture Organization of the United Nations, it is estimated that nearly one third of the food produced (about 1.3 billion tons) globally is not consumed. To help tackle this billion-dollar problem, an innovative solution is being deployed to detect one of the key factors driving food waste: Spoilage due to fluctuations in temperature.

To get to the dinner table, food must travel great lengths to preserve that farm fresh quality. Refrigerated shipping units and storage facilities are essential to reducing bacteria growth and by using an automated smart-refrigeration solution, a food-safe environment can be maintained throughout the journey with little supervision. Traditional food temperature monitoring is reliant on staff to periodically check temperature levels and make adjustments as necessary. This process is not scalable, meaning that with a larger facility or an increased number of food displays, it becomes increasingly labor intensive and inefficient. If employees are preoccupied, periodic check-ins may be delayed or missed entirely, leading to gaps where temperature fluctuations are not addressed, opening the door for increased bacteria growth and food waste.

To solve this issue, Internet of Things (IoT) sensors can be deployed in shipping vehicles, displays, refrigerators, and storerooms to provide accurate and consistent monitoring of temperature data. When a temperature fluctuation occurs, the sensors will send a signal to a low power, wide area network (LPWAN) gateway application. The information is then relayed to a network server, where it is routed to application servers or Cloud IoT services. The data is then processed and sent to the end user through a desktop or smartphone application. What’s more, in the event of a power outage, these long range, low power wireless enabled IoT devices are battery powered and consume minimal energy, allowing for consistent off-grid temperature tracking.

These connected devices can be found globally in a variety of use cases ranging from quick service restaurants to full service grocery stores, with an end goal of ensuring appropriate temperature levels for food. To support connectivity for these devices, an open network protocol is used to ensure the devices can be scalable and globally deployed. Two recent use cases where the long range, low power wireless devices and LoRaWAN protocol were used to actively monitor temperature fluctuations are Axino Solutions (Axino) and ComplianceMate.

Axino recently integrated LoRa devices and LoRaWAN protocol into its line of smart refrigeration solutions with the goal of combatting food waste. The solution combines sensor technology with automated data communication providing a substantial increase in measurement quantity and quality. Additionally, stores found a significant reduction in metering and operating costs after sensor deployment. This smart refrigeration solution has been globally deployed and is currently used by Switzerland’s largest supermarket chain, Migos. Axino’s sensors can be quickly installed, utilizing a magnet to attach to a refrigerator’s infrastructure. The sensors monitor temperature in real time, are accurate to one degree Celsius and can be pre-programmed to adjust refrigerator temperatures to ensure that food is stored in a safe environment. By having access to real time data and automatic temperature adjustment, supermarkets were able to eliminate human error, prolong shelf life and pass energy savings off to the customers.

The challenge for any wirelessly connected device is the presence of physical barriers that will block signals. Steel doors, concrete and insulation are some of the key considerations when developing a smart solution, especially in restaurants using large freezers. ComplianceMate partnered with Laird Connectivity and found that devices on a LoRaWAN-based network produces a more reliable signal than its Bluetooth counterpart. This IoT solution has been deployed in some of your favorite restaurant chains such as Shake Shack, Five Guys, Hard Rock Café, City Barbeque, and Hattie B’s and has already proved to be a huge asset. For instance, a sensor deployment saved $35,000 to $50,000 worth of inventory in a Hattie B’s location when downtown Nashville experienced a sudden power outage in 2018. The LoRa-based alert system immediately notified store management, allowing them to act quickly and prevent food spoilage.

Reducing global food spoilage is a monumental task. From farms to grocery stores and restaurants, technology must play a critical role, ensuring food remains at a safe temperature, preventing unnecessary spoilage. In the era of connectivity, businesses will turn to LoRa-based IoT deployments for its flexibility, durability and ability to provide real-time information to employees and decision makers to not only maintain strict industry standards in food safety, but to also pass savings on to their valued customers.
