Who wants shredded olive leaves on their pizza instead of oregano? Herbs and spices keep being a target for food fraud, a European Commission study that analyzed nearly 1,900 samples revealed. The study showed that about 20% of herbs and spices are manipulated, with oregano leading the top of the list, followed by spices that include pepper, cumin, curcuma, saffron and paprika. Europe is a leading importer of herbs and spices at 300,000 tons a year. The entire supply chain from country of origin, processing, packaging, importing to distribution, is potentially vulnerable to fraud. In most cases, undeclared plant material was added, and sometimes toxic dyes were found—and these are detrimental to human health.

Using Artificial Intelligence May Add More Transparency to the Food Supply Chain

By Emily Newton

Food industry professionals know how supply chain transparency plays a major role in keeping everything running smoothly. Brand representatives want confirmation that their agricultural partners can fill upcoming orders. If things go wrong and people get sick from what they eat, better visibility is vital in addressing and curbing such issues.

Artificial intelligence (AI) is a critical part of better food supply chain awareness among all applicable parties. This article briefly discusses some interesting examples.

Applying AI to Crop Management

Even the most experienced agricultural professionals know farming is far from an exact science. Everything from pests to droughts can negatively impact a growing season, even if a farmer does anything they can to influence production in their favor.

However, AI can help predict yields, enabling farmers to maintain transparency and set accurate expectations for parties further down the supply chain. That’s especially important in the increasingly popular farm-to-table movement, which shortens how far produce travels and may entail using it on the same day someone picks it.

One newly developed machine-learning tool relies on computer vision and ultra-scale images taken from the air to categorize lettuce crops. More specifically, it captures details about the size, quality, and quantity of the heads. Combining that with GPS allows more efficient harvesting.

Tracing Foodborne Illness

CDC Statistics indicate foodborne illnesses sicken one in six people every year in the United States. FSMA contains rules and actions for food processing facilities to prevent such instances, but outbreaks still happen. AI could be yet another useful mitigation measure.

Researchers at the University of Georgia determined that, since the 1960s, approximately a quarter of Salmonella outbreaks have been from the Typhimurium variation. They trained a machine-learning algorithm on more than 1,300 Typhimurium genomes with known origins. The model eventually achieved 83% accuracy in predicting certain animal sources that would have the Typhimurium genome. It showed the most accuracy with poultry and swine.

Reducing Food Waste

Waste is a tremendous problem for the food supply chain. In the United States, data shows that upwards of 40% of packaged consumables get discarded once they reach the use-by date. That happens whether or not the products are actually unsafe to eat.

However, better visibility into this issue has a positive impact on food distribution. For example, some restaurants give people discounted meals rather than throwing them away. In other cases, grocery stores partner with charities, helping people in need have enough to eat.

Scientists in Singapore have also created an electronic “nose” that uses AI to sniff out meat freshness. More specifically, it reacts to the gases produced during decay. When the team tested the system on chicken, fish and beef, it showed 98.5% accuracy in its task. Using AI in this manner could bring transparency that cuts food waste while assuring someone that a food product is still safe to eat despite the appearance of it being expired based on Best Before’ labeling.

Removing Guesswork From Dynamic Processes

People are particularly interested in how AI often detects signs that humans miss. Thus, it can often solve problems that previously proved challenging. For example, even the most conscientious farmers can’t watch all their animals every moment of the day and night, but AI could provide greater visibility. That’s valuable since animal health can directly impact the success of entire farming operations.

One European Union-funded AI project took into account how animal health is a primary factor in milk production. The tool compared cows’ behaviors to baseline levels and characteristics of the animals at the most successful farms. It then provided users with practical insights for improvement. Europe has at least 274 million dairy cows, and their milk makes up 11%-14% of Europeans’ dietary fat requirements. Those statistics show why keeping herds producing as expected is critical.

AI is also increasingly used in aquaculture. Until recently, fish farming professionals largely used intuition and experience to determine feeding amounts. However, that can lead to waste. One company uses artificial intelligence to sense fish and shrimp hunger levels and sends that information to smart dispensers that release food. The manufacturers say this approach causes up to a 21% reduction in feed costs. Other solutions track how much fish eat over time, helping farmers adjust their care protocols.

Fascinating Advancements in Supply Chain Transparency

These instances are only a sampling of what AI can do to support the food supply chain. Although most of them are most relevant to producers, consumers will likely reap the benefits, too. For example, some food labels already show the precise field associated with the potatoes used for a bag of chips. Once technology reaches a point where most consumers could have advanced AI apps on their phones, it could be a matter of aiming a smartphone’s camera at any food product and instantly seeing the path it took before reaching the consumer. It’s too early to know when that might happen. Nevertheless, what’s already possible with innovative technology is compelling in its own right and makes people rightfully eager to see what’s on the horizon.

Planning Is Key Component of Listeria Prevention

By Matt Regusci

ASI Food Safety

Reading the news in recent months, it seems like there is a new outbreak every week or at least a new recall of various food products contaminated with Listeria, specifically Listeria monocytogenes. Companies have recalled broccoli, kale, cantaloupes, smoked salmon (lox), mushrooms, soft cheese, sprouts, frozen chicken, and even hot dog buns in the last several months.

Listeria monocytogenes is a species of pathogenic bacteria that is very unique. Unlike many pathogens that are mainly fecal bacteria, like E. Coli and Salmonella, Listeria can be found just about anywhere including soil, water, dust and animal feces, to name a few.

We are around Listeria all the time. For example, when moms encourage their children to play outside to enhance their immune systems, one of the bacteria kids are likely exposed to is Listeria. This kind of exposure is generally acceptable, as the vast majority of people that get sick from Listeria exposure typically ingest quite a bit of it. That’s why it is essential to get in front of Listeria to avoid ready-to-eat products from becoming contaminated.

Listeria is one of the few bacteria to survive freezing temperatures and grow, albeit slowly, in a refrigerator. The exact range for growth of Listeria is 39.2°F (4 °C) to 98.6°F (37°C). To successfully kill Listeria using temperature controls, it must be cooked at least at 165°F (73°C). Left at room temperature, the pathogen grows rapidly. If you have ready-to-eat food contaminated with Listeria and it is taken out of the fridge, left on the counter for a couple of hours, then eaten, it’s a recipe for disaster.

If you are healthy, the vast majority of the Listeria bacteria will be attacked and killed by the immune system, preventing the ability for infection to take hold. If the immune system is compromised by conditions such as cancer, AIDS, pregnancy, geriatrics, etc., then Listeria becomes an infection called Listeriosis—an invasive infection.

The FDA and the CDC published some facts about Listeriosis and foodborne illness in general, and the diagnosis is stark. The FDA estimates that 1 in 6 Americans or 43 million people will get a foodborne illness annually. Of those that get sick, the FDA estimates 128,000 will be hospitalized, and about 3,000 die.

In the United States, the CDC estimates that about 1,600 people will get Listeriosis each year, and of those cases, 1,500 will be hospitalized (94%), and 260 will likely die. Listeriosis has a mortality rate of 20-30%, according to the FDA. Unfortunately, these numbers indicate that if the doctor diagnoses you with Listeriosis, the chances of survival are low.

According to FDA research, you are 18 times more likely to contract a Listeriosis infection if you are pregnant, and 16–27% of all Listeriosis infections are in pregnant women. While most other adults show signs of gastrointestinal symptoms once contracting Listeriosis, the FDA says a pregnant woman experiences a fever for a few days, and about 20–30% will ultimately miscarry.

The unique thing about Listeria is the incubation period could last up to 70 days. A possible scenario could be a person eating cantaloupe from a farm with a known Listeria outbreak and then 70 days later showing signs of Listeriosis. This was a reality during the Jensen Farms outbreak, where people were terrified that they may have been infected from Listeriosis after eating cantaloupe. Still, they had to wait for six weeks for assurance they were safe.

What Steps Should Industry Take to Prevent or Mitigate the Presence of Listeria?

The first step is to kill Listeria and prevent it from contaminating food. To kill this particular pathogen, heat and/or sanitization is necessary. The best way to avoid contamination is by cooking food, but cleaning and sanitizing regularly is the next best measure if you can’t cook the product.

All food manufacturing facilities need a cleaning and sanitizing routine. Typically, when a Listeria outbreak occurs, it is because of a series of unfortunate errors in quick succession. Facilities need to practice regularly on finding the potential errors in a cleaning/sanitizing system and fix them immediately. This attention to detail and strategy help correct the problem before an issue arises.

The same is important for the kitchen of a restaurant. Keep raw products away from cooked products. Utilize different sections within the kitchen to prep food in various stages, use separate cutting boards and be sure to use different utensils on raw vs. cooked food. Also, have a solid cleaning and sanitizing routine to kill lingering Listeria in the facility.

The second step is a solid continual testing regimen. A testing rotation is an effective tool in the pathogen prevention arsenal. Every facility should utilize an environmental testing program that regularly looks for Listeria in the facility. While all use outside certified labs, some also have in-house labs looking, more frequently, for pathogens. For instance, few fresh produce companies test the wash water for pathogens in every lot. If they find even the smallest trace of any pathogen, including Listeria, they trash it.

Another effective testing technique is “search and destroy”. In the “Search” process your team swabs everything in the facility looking for Listeria in the facility. When you do find an area with Listeria then you swab everything within a radius starting with one foot, expanding to three feet, then even wider to six feet, etc. until you find every major contamination point. Flag those areas as hot spots for continual checks in your future testing rotation.

The extremely important step three is the cold chain. Cold chain systems help reduce the growth of foodborne pathogens. To minimize the growth of pathogens, including Listeria, it is important to keep products cold at all times possible. This includes harvesting, packaging, storing, distributing, and especially. Also, consumers can play a role in helping reduce contamination by keeping food cold and putting it in the refrigerator or freezer as soon as possible. Every minute a product is left at room temperature can mean massive bacteria growth.

Step four is knowing where your food comes from. In the food industry, we call this supply chain compliance and traceability. A relationship of trust between food producers, suppliers and consumers is vital for the food industry. Raw and finished food products are moving through the supply chain rapidly, so good communication is crucial so that contaminated products are removed quickly to contain an outbreak and save lives.

With these practices in place, we can keep the Listeria outbreaks to a minimum. However, extra care is recommended if you are pregnant, immunocompromised, or over the age of 65. In fact, the FDA has a list of foods to avoid or at least cook very thoroughly. These include deli meat, raw vegetables, and unpasteurized milk products, to name a few.

You Are What You Eat: Meeting the Demand For Sustainable Practices and Transparency

By Waylon Sharp
No Comments
Waylon Sharp, Bureau Veritas

A very volatile sector, there are always new trends, opportunities and challenges in the food space, as a multitude of factors—including global climate and geopolitical challenges—can cause supply chain disruptions. Sustainable audits are heightening in demand, in order to validate company claims and provide consumers with peace of mind, as the industry continues to evolve with new ingredients, processes and technologies in play.

Consumers Today Demand Sustainable Practices and Transparency

The shift towards sustainability has further been accelerated by COVID-19, as the pandemic has made for more ethical and conscious consumers. According to research from Forrester, 68% of highly empowered consumers plan to ramp up their efforts to identify brands that reduce environmental impact. While there are numerous audits to measure sustainability and social responsibility, trending focus areas in the food space today are around sustainable packaging, water usage and food waste.

Three Ways Food Processors and Manufacturers Can Reduce Their Footprint

Key players across the food industry are stepping up to the challenge and finding innovative ways to minimize their environmental impact. The following are three ways food processors and manufacturers can reduce their footprint.

  • Use Environmentally Friendly Packaging: Food packaging is a major source of waste and pollution. In fact, containers and packaging make up a major portion of municipal solid waste (MSW), amounting to 82.2 million tons of generation in 2018, according to the EPA. Unfortunately, most packaging is designed as single-use, and is typically thrown away rather than reused or recycled. Given the impacts of packaging on the environment, more manufacturers are looking into packaging options that reduce waste and boost sustainability, including wood- and paper-based alternatives. Other manufacturers are developing innovative alternative packaging from biodegradable materials. The same rings true for takeout and grocery delivery, as the demand for home consumption grows, retail and foodservice companies are considering utilizing more sustainable packaging or reduce the use of virgin plastics to offset their impact.
  • Increase Energy and Water Efficiency: Food processing and manufacturing are energy- and water-intensive. In fact, according to the World Resources Institute, the 1.3 billion tons of wasted food annually also includes 45 trillion gallons of water. Water conservation methods can be implemented throughout the entire food chain—from selecting more efficient crops, to using less water within processing facilities and ultimately reducing food waste on the backend of the chain.
  • Reduce Food Waste: According to the Food and Agriculture Organization of the United Nations (FAO), nearly one-third of food produced for human consumption gets wasted each year. In fact, the carbon footprint of food waste is greater than that of the airline industry. This also includes the waste of resources used to produce the food including water, soil, transportation and labor. By improving processing and manufacturing efficiencies, we can reduce waste and better manage resources. Implementing systems to categorize and assess food waste can help identify areas for improvement and enable your team to develop a plan to correct.

Value-Add of Sustainability

Sustainability provides benefits to the consumer, the manufacturer and society-at-large. The consumer feels better about making a purchase that is not only better for the planet, but that may also provide health benefits to themselves and their families. The Organic Trade Association’s 2021 U.S. Organic Industry Survey highlights this trend, as organic food has the reputation of being better for your health and more sustainable for the planet. Organic food sales were up 12% in 2020, the highest growth rate in this category in over a decade.

Intrinsically, manufacturers with sustainable programs in place feel better about the work they are doing, knowing that they are supporting a better world. Companies that publicize their green programs and back them up with the applicable certifications can also attract top employees, despite today’s talent wars. Employees are zeroed in on corporate social responsibility and desire to work for a company that aligns with their purpose.

As it relates to the bottom line, the common misconception is that the sustainable choice will cost more. However, as sustainable supply increases due to consumer demand, companies are able to source sustainable inputs more affordably. Furthermore, they can communicate their commitments via certification bodies, through public forums and by labeling products based on their certifications. These approaches help reach and educate consumers at different levels—from their initial research of products to purchases from the store shelves.

Key Certifications and Auditing Technology

To reduce their environmental footprint throughout the value chain and implement more sustainable business practices, food companies can move toward a circular economy business model. By renewing, reusing and recycling materials at every stage of the food supply chain, companies can preserve the critical resources that allow their business to flourish.

There are a wide range of services help food producers make the transition to a more sustainable business model. This includes the GHG emissions verification, and management system auditing and certification or training to standards like ISO 14001 (Environmental Management System), ISO 24526 (Water Efficiency Management System), AWS (Alliance for Water Stewardship), ISO 50001 (Energy Management System) and SA8000 (Social Accountability standard), as well as SMETA (Sedex Members Ethical Trade Audit) audits. There are also a range of food sustainability-related product certifications including Organic, MSC, ASC and RSPO.

Auditing technology supports a range of requirements and helps teams set achievable targets. It can be used to analyze packaging materials, categorize and assess food waste, and monitor water usage. Newer auditing technology is now blockchain enabled to assess raw materials and packaging, and to ensure third party partners are also socially responsible. This information is packaged into a blockchain solution so that food companies can be confident that the auditing information is correct and secure. Furthermore, this technology provides the added visibility into their network should they have a recall.

How To Initiate or Ramp Up Your Sustainable Programs

For companies interested in kicking off a sustainability program, or branching into new levels of sustainability, a great place to start is training, in order to understand the audit standard. Early on in this process, ensure all parties are onboard and aware of the certification process and related costs—from managers who will be implementing the program daily to board level executives providing the final sign off. Doing this helps allocate sufficient time and resources and avoids surprises down the road.

It’s helpful to work with a third-party consultant through this process, as they are able take a birds-eye-view look to identify gaps in the program and help you achieve specific certification requirements that meet your unique food product needs. If your team works with a consultant to put together a plan that includes auditing, testing, inspection and certification, the right partner can verify that the program meets all the requirements necessary for the certification.

To keep your program running efficiently, arrange regular trainings for employees to stay up to date on the latest requirements and fill any gaps. For more specialized programs, it’s also a good idea to set aside standalone training sessions to avoid information overload.

As the industry continues to innovate, there will be more ways to reduce waste throughout the entire supply chain and build more efficient business models that are better for the company, consumers and the planet. Looking ahead to next year and beyond, the trend towards sustainability and transparency will press on. Ultimately, companies that take the extra steps to be more sustainable are setting a higher standard for industry and supply chain partners and building a pathway for long-term success.

Billions of Dollars Lost to Food Waste, Tech Exists to Reduce It

By Scott Deakins
No Comments
Scott Deakins, Deacom

Food waste is a massive global problem led by the United States. According to the USDA, an estimated 30–40% of the country’s food supply ends up in landfills—most of it at the retail and consumer levels. This amounted to approximately 133 billion pounds and $161 billion worth of food wasted in 2010 alone, which prompted the USDA and the Environmental Protection Agency to launch the U.S. Food Loss and Waste 2030 Champions initiative in 2016. Businesses and other organizations can join the ranks as champions by committing to a 50% reduction of food loss and waste by 2030.

That’s a noble goal, but those businesses will only be able to achieve their objective with technologies that reduce food waste in production and the supply chain. Food lost in this medium is hardly insignificant. At least 10%—or billions of pounds of food—is wasted in acts as small as over-ordering or in transport. This is, in short, the result of errors in resource planning.

After an extremely difficult year, food process manufacturers can no longer afford to generate that level of waste. Fortunately, technologies already exist to help the industry regain control of its production, storage and forecasting, and can facilitate leaner businesses and less waste.

Eliminate Human Error and System Inconsistencies

There have been a lot of changes in the way food is grown, harvested, delivered and sold over the last few decades, yet little progress has been made when it comes to unnecessary waste. The Commission for Environmental Cooperation reports that food loss and waste can occur post-harvest due to inaccurate supply and demand forecasting, grade standards for size and quality, and deficiencies in refrigeration. Even the packaging can cause problems if it is inefficient or ineffective.

These and other problems lead to waste—some up front before the product is ever sold to consumers, others down the line after an item has been purchased, leading to a recall. If inventory records are anything less than 100% accurate from formulation through shipment, additional challenges will follow. Though it is not heavily considered in an FDA audit, manufacturers still need the ability to instantaneously report on any aspect of their inventory history, regardless of the ERP software from which data is pulled. ERP systems with bolt-on modules often fail in this regard. If functionalities of the sub-systems are not designed for strict lot tracking, or if those sub-systems are not designed exactly the same, errors are inevitable.

Workarounds can be implemented, but they cannot account for processes that still need to be performed manually, which increases the likelihood that lot tracking accuracy will fall short. Inefficiencies are further exacerbated by sub-systems that handle actions differently, but the challenges don’t end there.

Problems can also develop when data has to be shared across more than one module, database or even system, which may inspire the use of outside solutions, such as an Excel spreadsheet, compounding the issues at hand. Makeshift solutions increase the risk that an incorrect lot number will be entered or that someone will forget to delete a number after a lot was de-issued and re-issued. Any of these cracks in the operational foundation will inevitably deduct from the 100% inventory accuracy that’s necessary for a smooth recall process—anything less will lead to a greater impact on the business.

The only real solution is to eliminate the potential for human error and system inconsistencies altogether—and that can only be accomplished with a configurable ERP solution that handles all business processes from one system and one database and can easily adapt to changing regulation and recipes. Without it, true strict lot control—meaning 100% inventory accuracy with perfect record keeping and the ability to instantly report on any aspect of the inventory history—cannot be achieved.

Reduce Inventory Variance and Grow without Unnecessary Expansions

There are aspects of food waste that can be controlled, including inventory variance, which occurs when items are lost, misplaced or miscounted. This is particularly problematic for packaging and ingredients, causing issues at the production level—finished products cannot be made if there aren’t enough items to complete the process, which is also bad for the bottom line. Inventory variance may occur if deliveries are not verified to confirm that ordered ingredients were actually received or may happen if items are entered incorrectly or simply misidentified.

Variance is more than a nuisance—it can be quite costly. For example, Silver Spring Foods encountered this firsthand when it discovered that its inventory variance commonly reached between $250,000 and $300,000. The company, which debuted in 1929 when founder Ellis Huntsinger started growing horseradish and other vegetable crops, now produces the number-one horseradish retail brand in the United States. With more than 9,000 acres of prime Wisconsin and Minnesota farmland, Silver Spring realized that it had outgrown its outdated ERP solution.

The company initially thought that it had reached capacity and could only grow further by physically expanding its building with an additional manufacturing line that would require new hires to come aboard. In reality, the company needed an ERP solution that could keep up with its impressive level of growth.

More specifically, Silver Spring Foods wanted an ERP system that could tie together several elements, including customer service, accounting, manufacturing, purchasing and shipping within a single tool. The company needed a solution that offered strong data mining and reporting functionality, as well as strong sales reporting, sustainable tech support capabilities and would not exceed ERP budget allocations. It was equally important to have an ERP solution that was configurable without customization, prioritizing speed and efficiency while offering predictable quality and cost of ongoing IT support and maintenance.

After upgrading to a solution that met all of its requirements, Silver Spring Foods was able to gather all data in one system that brought together multiple software integrations, including CRM. This allowed the firm to fine-tune its material purchases to match current production needs, sales forecasts and production schedules. More importantly, inventory variance was reduced to $90,000 during the first year and now falls within a range of just $1,800 to $2,500. By improving inventory management, unearthing new efficiencies and proving that Silver Spring had not yet reached capacity, the company was now able to grow without adding additional square footage.

Don’t Let Waste Cut into Productivity

Food growers, processors and supply chains cannot afford to let waste cut into their productivity or their bottom line. They need to be able to keep track of everything, achieving true strict lot control to limit the damage caused by a recall. They also need to be able to improve food management and reduce inventory variance. These and other advantages can only be attained with the right ERP technology, however, so businesses must choose wisely before making an investment.

Key Trends Reinforce Food Allergen Testing Market Across North America

By Saloni Walimbe

Allergens

The food allergen testing industry has garnered considerable traction across North America, especially due to the high volume of processed food and beverages consumed daily. Allergens are becoming a significant cause for concern in the present food processing industry worldwide. Food allergies, which refer to abnormal reactions or hypersensitivity produced by the body’s immune system, are considered a major food safety challenge in recent years and are placing an immense burden on both personal and public health.

In 2019, the most common reason behind recalls issued by the USDA FSIS and the FDA was undeclared allergens. In light of this growing pressure, food producers are taking various steps to ensure complete transparency regarding the presence of allergenic ingredients, as well as to mitigate risk from, or possibly even prevent contact with, unintended allergens. One of these steps is food allergen testing.

Allergen detection tests are a key aspect of allergen management systems in food processing plants and are executed at nearly every step of the process. These tests can be carried out on work surfaces, as well as the products, to detect any cross contamination or allergen presence, and to test the effectiveness of a food processing unit’s cleaning measures.
There has been a surge in awareness among consumers about food allergies and tackling the risk of illnesses that may arise from consuming any ingredient. One of the key reasons for a higher awareness is efforts to educate the public. In Canada, for example, May has been designated “Food Allergy Awareness Month”. It is estimated that more than 3 million people in Canada are affected by food allergies.

The size of the global food allergen testing market is anticipated to gain significant momentum over the coming years, with consistent expansion of the dairy, processed food and confectionary segments.

Understanding the Prevailing Trends in Food Allergen Testing Industry

Food allergies risen nearly 50% in the last 10 years, with a staggering 700% increase observed in hospitalizations due to anaphylaxis. Studies also suggest that food allergies are a growing health concern, with more than 250 million people worldwide estimated to be affected.

Although more than 170 foods have been identified as causing food allergies in sensitive consumers, the USDA and the FDA have identified eight major allergenic foods, based on the 2004 FALCPA (the Food Allergen Labeling and Consumer Protection Act). These include eggs, milk, shellfish, fish, peanuts, tree nuts, soybean, and wheat, which are responsible for 90% of allergic reactions caused due to food consumption. In April 2021, the FASTER (Food Allergy Safety, Treatment, Education, and Research) Act was signed into law, which categorized sesame as the ninth major food allergen.

This ever-increasing prevalence of allergy-inducing foods has presented lucrative opportunities for the food allergen testing industry in recent years since food processing business operators are placing a strong emphasis on ensuring transparency in their products’ ingredient lists. By testing for allergens in food products, organizations can accurately mention each ingredient, and thereby allow people with specific food allergies to avoid consuming them.

Several allergen detection methods are used in the food processing industry, including mass spectrometry, DNA-based polymerase chain reaction (PCR) as well as ELISA (enzyme-linked immunosorbent assay), to name a few. The FDA, for instance, created a food allergen detection assay, called xMAP, designed to simultaneously identify 16 allergens, including sesame, within a single analysis, along with the ability to expand for the targeting of additional food allergens. Such industry advancements are improving the monitoring process for undeclared allergen presence in the food supply chain and enabling timely intervention upon detection.

Furthermore, initiatives, such as the Voluntary Incidental Trace Allergen Labelling (VITAL), created and managed by the Allergen Bureau, are also shedding light on the importance of allergen testing in food production. The VITAL program is designed to support allergen management with the help of a scientific process for risk assessment, in order to comply with food safety systems like the HACCP (Hazard Analysis and Critical Control Point), with allergen analysis playing a key role in its application.

ELISA Gains Prominence as Ideal Tool for Food Allergen Testing

In life sciences, the detection and quantification of various antibodies or antigens in a cost-effective and timely manner is of utmost importance. Detection of select protein expression on a cell surface, identification of immune responses in individuals, or execution of quality control testing—all these assessments require a dedicated tool.

ELISA is one such tool proving to be instrumental for both diagnostics as well as research). Described as an immunological assay, ELISA is used commonly for the measurement of antibodies or antigens in biological samples, including glycoproteins or proteins.

While its utility continues to grow, ELISA-based testing has historically demonstrated excellent sensitivity in food allergen testing applications, in some cases down to ppm (parts per million). It has a distinct advantage over other allergen detection methods like PCR, owing to the ability to adapt to certain foods like milk and oils, where its counterparts tend to struggle. The FDA is one of the major promoters of ELISA for allergen testing in food production, involving the testing of food samples using two different ELISA kits, prior to confirming results.

Many major entities are also taking heed of the growing interest in the use of ELISA for food allergen diagnostics. A notable example of this is laboratory analyses test kits and systems supplier, Eurofins, which introduced its SENSISpec Soy Total protein ELISA kit in September 2020. The enzyme immunoassay, designed for quantitative identification of soy protein in swab and food samples, has been developed by Eurofins Immunolab to measure residues of processed protein in various food products, including instant meals, chocolate, baby food, ice cream, cereals, sausage, and cookies, among others.

In essence, food allergens continue to prevail as high-risk factors for the food production industry. Unlike other pathogens like bacteria, allergenic proteins are heat resistant and stable, and cannot easily be removed once present in the food supply chain. In this situation, diagnostic allergen testing, complete segregation of allergenic substances, and accurate food allergen labeling are emerging as the ideal courses of action for allergen management in the modern food production ecosystem, with advanced technologies like molecular-based food allergy diagnostics expected to take up a prominent role over the years ahead.

Ask the Expert: ImEPIK Discusses Supply Chain Controls and PCQI Responsibilities Under FSMA

Kathryn Birmingham, ImEpik

Dr. Kathryn Birmingham, one of ImEPIK’s PCQI training experts, provides guidance to Juan, a future PCQI in a plant that receives ingredients for ready-to-eat energy bars.

Juan: I’m new on the food safety team at a small company and the next person to be trained as a PCQI. Our team wants to make sure we are meeting the requirements in our food safety plan under the Preventive Controls for Human Food Rule in FSMA. There are a lot of players along our ingredients supply chain. Who is ultimately responsible for product safety?

Kathryn Birmingham: As you know Juan, if you manufacture, process, hold or pack an ingredient or food product, food safety is your responsibility. For all of the players along the supply chain FSMA focuses on risk assessment and identifying hazards and preventive controls when required. Your team must have a plan and implement verification activities for the supply chain preventive controls for the food ingredients with hazards you have identified needing a control.

Juan: So, we are sourcing chocolate from a number of suppliers or our bars. They all provide COAs with the shipment that tell us the chocolate is manufactured to be free of pathogens like Salmonella. Usually we get a laboratory report on the sample testing for vegetative pathogens from the supplier for each shipment. We put that in our food safety plan to verify that the hazard was controlled by the supplier. But one of the suppliers has not provided sample testing results we requested. We have finished product to get out the door, but we have to ensure our product doesn’t harm consumers. On top of that, we can’t risk a costly product recall.

Kathryn: Right, Juan. That Certificate of Analysis may not be enough to verify that your chocolate supplier is effectively controlling for the hazard of Salmonella. For your product process flow the chocolate will never have a kill step to mitigate the hazard. If you cannot be sure that the hazard has been significantly minimized or prevented before receipt of the chocolate – per section 117.410 in the PCHF Rule – you have some choices to make. If you are using a foreign supplier there are considerations if the supplier is or is not in compliance with the FDA’s Foreign Supplier Verification Program.

Juan: So it looks like we may have to take on the cost and additional time of sample testing?

Kathryn: Remember, supplier approval is based on performance. If your supplier does not give you the evidence for verification you may need to conduct an onsite audit, perform sampling and testing and review other supplier records. You decide if the supplier meets your Supply Chain Control Program or Foreign Supply Chain Control Program.

Juan: My team members need to learn more about what we need to do to comply with FSMA and the PCHF Rule. Tell me about what we can learn through PCQI training.

Kathryn: Preventive Controls Qualified Individuals are trained in a methodical process for decision-making on hazards and preventive controls. The best training fosters a positive food safety culture and includes practice on team scenarios.

A PCQI must be able to identify hazards associated with a product and process, determine the appropriate preventive controls and develop associated monitoring and corrective actions for hazards that are identified. PCQIs must also establish and implement appropriate verification activities for the application of preventive controls. All of that is included in the food safety plan they oversee.

Juan: What choices do we have for online PCQI training?

Kathryn: First choose your food safety team members. If your company is registering with the FDA you are required to have at least one PCQI at each facility. Most companies train multiple or back up employees for the PCQI role to ensure they are covered during vacations, sick time, various shifts or employee turnover.

Look for courses that include the FDA’s standard curriculum, like ImEPIK’s PCQI Online. The PCHF Rule does not require that PCQIs hold a specific training certificate, but FDA inspectors want to see that the PCQI has been successful in a training with the requisite learning objectives and content. There are many PCQI training options on the market. Some providers claim that their training is the only accepted training – that’s simply not true.

Look for courses that have a multiple of scenarios with different food products and challenge situations for practice and wider breadth of learning.

ImEPIK’s PCQI Course is interactive and 100% online. The ten-module training is entirely self-paced thus does not require travel or scheduling on-line webinars or sessions. You simply log in, work through the course as you have time, and earn your completion certificate to document in your food safety plan. If you take a break, the work you have done will be saved, and you pick up where you left off when you return to the course. This allows for reflection and practice in the workplace as you move through the modules.

It’s an ever changing environment for the food safety professional and quality training makes a big difference in keeping up with changes and staying regulatory compliant. Take PCQI Online and position yourself and your facility for food safety success.
