Glove Polymers: The Unregulated Food Safety Threat

By Steve Ardagh

Various polymers are used in food contact applications that include food packaging and disposable gloves. More than 30 different types are used in packaging and up to six in disposables gloves. In terms of safeguards for the U.S. food supply as well as user safety, it is worth noting that 87% of the production of packaging polymers is based in the United States and subject to FDA regulation and monitoring. On the other hand, all (100%) of the 100 or more glove factories supplying the United States are based in Southeast Asia, according to a report by the British Medical Association and are not subjected to the same FDA monitoring or scrutiny.1

Packaging production is carefully overseen by the FDA, is included in FSMA, and covered in the HACCP process. Toxicology of food packaging is carefully prescribed and subject to strict enforcement action from production to storage.

Glove factories, however, are generally self-regulated, with FDA compliance required for a rough outline of the ingredients of the gloves rather than the final product. Few controls are required for glove manufacturing relating to the reliability of raw materials, manufacturing processes and factory compliance. A clear opportunity exists for accidental contamination within the glove-making process. More significantly, because of the geographic and economic implications in workforce and workplace conditions, intentional contamination potential is greatly increased. Polymer gloves utilized in food processing and service have been implicated in 15–18% of foodborne illness outbreaks in the United States.2

There is a striking difference in the requirements for these two different types of food contact polymers. Food packaging is extensively regulated, gets tested within the context of completed food product and has production primarily in the United States under close supervision. Disposable gloves, on the other hand, rely on self certification, often with testing results only on glove constituents, and little or no oversight of factory process and conditions. It seems as though this is a glaringly obvious but little accounted for risk to the U.S. food sector.

As a result, based on the root cause analysis of food cross contamination, a selection of tests and certifications, some of which are unique to the glove industry, are being implemented by one particular glove supplier. These tests ensure that their gloves coming into the United States are made in clean, well-run factories, free of any type of contamination and are consistent in material makeup to original food safe specifications. This glove fingerprint testing program consists of a number of proprietary risk reduction steps and targeted third-party testing methods, includes gas chromatography combined with mass spectroscopy (GC/MS, surface free energy determination, in vitro cytotoxicity analysis, and microbial viability-linked metagenomic analysis.

With a great deal of faith placed on a glove supplier’s ability to deliver disposable gloves sight unseen, I believe these tests are essential to further reduce the food safety risks associated with them. Objective…Zero surprises!

Lettuce

Although FDA is continuing its investigation into the source of the E.coli outbreak involving romaine lettuce grown in California, the CDC has declared the outbreak over. Contaminated romaine that caused illnesses should no longer be available, FDA stated in an outbreak update. Consumers will not need to avoid romaine lettuce, and retailers and restaurants do not need to avoid selling or serving the product, according to the agency. Suppliers and distributors need not avoid shipping or selling any romaine that is on the market either.

FDA has recommended that romaine lettuce is labeled with the harvest location and date, as well as whether it has been grown hydroponically or in a greenhouse. “ In case of future product withdrawals or recalls of romaine lettuce, this will help to limit the amount of product to be removed from the market and it will help consumers, restaurants and retailers determine that the romaine lettuce they are buying is from an unaffected growing region,” stated FDA. In addition, the detailed labeling should be available in stores, the agency states.

Food Safety Vs. Blockchain: Who Wins?

The jury is still out on how (and if) blockchain can contribute to a safer food supply. Whether or not there is a clear understanding of the technology, and its potential and pitfalls, is up for debate as well. “What is blockchain? This is the number one question that people have,” said Darin Detwiler, director, regulatory affairs of food and food industry at Northeastern University, who led a panel of experts as they deliberated over this hot topic during the 2018 Food Safety Consortium.

“Blockchain levels the playing field where we can connect people, resources and organizations in ways we’ve never done before to harness new ways of extracting value,” said Nigel Gopie, global marketing leader, IBM Food Trust at IBM.

What Is Blockchain?

Gopie provided an introductory definition of blockchain: Simply put, it is a series of blocks of information attached together. Each block is a box of information that stores data elements, and this data could be almost anything. Each block has a digital fingerprint associated with it; this fingerprint allows you to know that the block is unique and can attach to other blocks. When new blocks come into the chain, each block has a new fingerprint—one that is unique to that block and of the block before it. This allows the connection to happen, and enables visibility into the origin of each block.

Blockchain enables one book of business and provides three important benefits, said Gopie:

  1. Digital transactions
  2. Distributed ledger with one version of truth throughout the network
  3. Data is immutable

IBM’s Nigel Gopie breaks down the basic meaning of blockchain for attendees at the 2018 Food Safety Consortium.

Although blockchain can help to start the process of solving food issues surrounding safety, freshness, reduced waste and sustainability, the technology is only the foundation. A series of other components are important as well, said Gopie, and the following are some insights that the expert panel shared during their discussion.

2018 Food Safety Supply Chain Conference, Blockchain
Is the Food Industry Ready for Blockchain? Check out a dynamic panel about the technology from the 2018 Food Safety Supply Chain Conference.

Can Blockchain Actually Impact Food Safety?

Jorge Hernandez, chief food safety officer at Wholesome International: “To me, it’s a fantastic new technology that would allow the food industry to do a much better job of finding, from seed to fork, all of the processes and things that happen to that product. And in the future, [it] allows us to identify problems first and solve [them]. My problem is it being sold to companies…and not able to deliver on the promise… It bothers me that we are looking at a future that may or may not be there.”

Angela Fernandez, vice president, retail grocery & foodservice at GS1 US: “We’ve been working on traceability and transparency for over a decade—you have to be capturing the data needed, [and] we’re still working on getting it right. We’re just not there yet. I think it’s a great place for us to strive to go towards, but we’re still early in the stages of accepting it as a community.”

David Howard, vice president of corporate strategy at Pavocoin: “Blockchain itself is simply a technology. We’re all here because we’re just trying figure out what application we can use in business. Blockchain is a technology that can help all of you improve operational efficiencies for your bottom line.”

Is Blockchain a Barrier or a Fast Lane to Heightened Liability Concerns?

Shawn Stevens, food industry lawyer and founder of Food Industry Counsel, LLC: “I think the starting point is to ask ourselves what makes food unsafe. It’s a lack of transparency…What blockchain can do is illuminate entire segments of the industry…From a reactive standpoint, blockchain can help us identify a problem [and] solve it. From a preventive standpoint, if I have access to all this information regarding attributes and quality of supplier, I can make better decisions that protect my company.”

“We want to know more and be better informed. Once you know more, you better react and do something. If you’re getting this line of sight and you don’t react to it, that’s what exposes you to liability.”

Darin Detwiler, director, regulatory affairs of food and food industry at Northeastern University: “We need to look at the balance between the reactive use of blockchain and the proactive use.”

What Barriers Does Industry Need to Anticipate?

Fernandez: “The barrier of the standards and interoperability piece—that’s a big question our community is asking us. Scalability… standards are vital…I think that opens up a different discussion when talking about private versus public blockchain.”

Hernandez: “What is my ROI? The issue I have with blockchain is not only the investment in my organization, but I have to bring my entire supply chain with me if I want to get any benefit. There’s a good value proposition, but it requires you to get everyone on board. When you’re a large organization, it’s probably not that hard to do. But a small organization like mine where my suppliers are an Amish community that sells us cheese, that’s a huge mountain to climb. They don’t have the background [or] the technology, and even if they wanted to do it, it’s a big change for them. You’re asking me to make a change in my relationship with my suppliers.”

“Take a look at it from the business continuity [perspective]. What are the changes you’re going to have to make? And that changes that have to be made by everyone who works with you? We should not stay static. We should continue to look for things. If this is the technology that is going to move us forward, let’s start getting prepared.”

How the Government Shutdown Affects Food Safety

By Food Safety Tech Staff
No Comments
Alert

–UPDATE —January 9, 2019 – Today FDA Commissioner Scott Gottlieb, M.D. gave an update about food inspections in the context of the government shutdown. He chose Twitter to deliver his statement. He said FDA is expanding the scope of food safety surveillance inspections that are occurring during the shutdown to ensure that high-risk food facilities are address (31% of domestic inspections are high risk). He added that the agency continues to conduct all foreign food inspections.

“We assess risk based on an overall, cross-cutting risk profile. The primary factors contributing to a facility’s risk profile include: the type of food, the manufacturing process, and the compliance history of the facility. Commodities deemed high risk include, but aren’t limited to: modified atmosphere packaged products; acidified and low acid canned foods; seafood; custard filled bakery products; dairy products including soft, semi-soft, soft ripened cheese and cheese products, unpasteurized juices; sprouts ready-to-eat; fresh fruits and vegetables and processed fruits and vegetables; spices; shell eggs; sandwiches; prepared salads; infant formula; and medical foods.” – Scott Gottlieb, M.D., FDA

–END UPDATE–

As the third-longest government shutdown in U.S. history continues, businesses across industries are concerned about what resources are available.

At FDA, “All our work is important, but only some of our work is permitted to continue during a lapse in funding,” according to an agency statement. This work includes any activities that are considered “mission critical”:

  • Maintaining core functions that handle and respond to foodborne illness outbreaks
  • High-risk food recalls
  • Screening foods imported into the United States
  • The pursuit of civil and/or criminal investigations when the agency believes that the public health is at risk

At USDA, FSIS will continue much of its food safety activities Field inspection of meat, poultry and egg products will continue, as well as regulatory enforcement and product testing in labs. The agency will also continue its enforcement and food safety surveillance and investigations, which includes recall initiation, traceback/traceforward investigations.

“The agency must ensure adequate senior level management and coordination of the agency’s public health responsibilities during a shutdown. Excepted activities include responding to intentional and unintentional food safety events. A small number of individuals will support these activities for the duration of the shutdown, while others will be available on call if such an event occurs, including recall staff, scientists; recall communication specialists, significant incident specialists.” – USDA

In addition USDA/FSIS personnel at the agency’s three field labs are considered “excepted” during the shutdown. A full breakdown of FSIS activities that will continue are available on the USDA’s website.

How Supply Chain Digitalization and Data Helps Prevent Costly Recalls

By Gisli Herjolfsson
No Comments
Gisli Herjolfsson, Controlant

Recalls are something that food brands plan for but hope to never experience. They are an important public safety issue, but they also have a significant economic impact as well. At best, a product recall is a benign mistake that causes little more than aggravation and inconvenience for a few angry customers. At worst, the consequences can be tragic, both in terms of human and financial impact.

Industry research conducted by the Food Marketing Institute and Grocery Manufacturers Association places the average cost of a single recall at $10 million. That calculation includes only the direct costs of a recall. For the full, long-term costs, including direct and indirect liabilities, you’d need to further account for the immediate loss in sales, litigation costs, as well as any long-term damage caused from a loss in consumer confidence in your brand.

Consumers’ relationship with food is ever changing. They demand transparency about its contents, origin and safety, and for good reason. The World Health Organization estimates that nearly 1 in 10 people are sickened yearly from eating contaminated food, leading to 420,000 deaths. Consumers have long memories for businesses that poison them. The larger the size of your company and the more attention it receives, the potentially greater impact on your long-term business prospects. With the recent E. coli outbreaks tied to romaine lettuce, food safety is top of mind for consumers, and it is impacting entire market segments.

One of the easiest ways to prevent recalls associated with perishable foods is to ensure that food and beverage products are safely produced and continually kept at the right temperatures. Sounds easy, right? In reality, it is far from it.
Gaining end-to-end supply chain visibility can help you prevent costly recalls altogether. Data that today’s technology provides will be important for mitigating risk and protecting a brand’s reputation.

Get Proactive

The idea of prevention is paramount to FSMA. It’s clear that the FDA expects that once a producer or supplier discovers that something has gone wrong, they go back and figure out exactly what happened so that they can put measures in place to prevent it from happening again.

While current FDA guidelines and various EU safety regulations generally require that food can be tracked one step up and one step down the supply chain, this remains a very siloed approach to traceability and is open to risks—risks that producers, food retailers and restaurant brands cannot afford to take.

For USDA-regulated products, HACCP employs a similar process. Prevention is key, and if your monitoring measures miss an issue that could compromise food safety, you’ll need to go back and determine the root cause of the problem.
A cold food manufacturer can do a lot to control risks under its own roof, but how do you avoid costly recalls with ingredients or with temperature abuse after a product leaves the facility? Regulations or not, knowing where your ingredients and food products come from and being assured of their safety is critical in protecting your brand and company from the financial and reputational damage caused by a food recall.

Looking forward in the supply chain, maintaining the cold chain is necessary for many products, including fresh produce, frozen and deep frozen foods, and also those that must be kept at room temperature but still require temperature control. Even if you and your suppliers are incredibly careful and practice prudent safety measures, you may not have full visibility over who else is handling your products. If temperature mishandling by someone else necessitates a food recall or results in a food safety incident, it is still associated with your brand, even if you weren’t the direct culprit.

For many food retailer and restaurant chains, it is common practice for them to share their internal food safety guidelines with their suppliers and partners, and require that they prove a product’s source of origin, lifespan, how those products are stored and transported from point A to point B, as well as the environmental conditions in which foods are kept. Allowing suppliers and logistics partners to self-manage their supply chain does nothing to proactively ensure that they and a food brand aren’t in the headlines due to a food safety incident.

Digitally Connect the Supply Chain

This is where technology and data can play a critical role in managing your temperature-controlled food and beverage products. More and more food enterprises are utilizing Internet of Things (IoT) technologies that talk to the internet so they can collect supply chain data into dashboards and access it on demand.

IoT can be considered as a central nervous system for the supply chain. Through IoT, you can track shipments or trace temperature, moisture or other factors that can have an impact on food quality. Not only can you discover problems more rapidly with this technology, you can narrow the scope of recall. For businesses transporting temperature-sensitive products, this means they can manage product movement data in real-time and respond to issues before they lead to a food safety incident or product waste.

From a food production standpoint, IoT solutions can substantially reduce recalls from issues like labeling, processing and contamination. One of the primary causes of a food recall is microbiological in nature, with the majority of cases involving fruits and produce. IoT data can help detect issues further upstream in the supply chain and, since products will change hands several times before they reach a consumer, it can give you a complete picture of the product’s lifecycle—something that cannot be done with clipboards and ad hoc or periodic inspections.

Through cloud technology, food businesses can connect their end-to-end supply chain, analyze data, discover trends, illuminate weak points and directly respond to them to improve their overall processes.

Track and Trace Everything

Continuous and consistent tracking and tracing through technology not only simplifies recalls, it helps prevent them altogether. The only thing worse than being faced with a food recall is not knowing which products are affected or where exactly they are located.

Real-time temperature monitoring and product movement traceability technology can give you the confidence that foods are continuously kept at their required temperatures and remain safe for consumption. When you need to track and trace an ingredient or product, time is often of the essence. Delays may mean more resources and efforts are spent in producing something that may be rejected, or worse, recalled, or that the potentially impacted product isn’t isolated in time.

The digital integration of suppliers and other partners is vital if a food enterprise wants to have more control over its cold chain. Consumer demand for social responsibility and ethical business operations means that businesses need to provide greater visibility and transparency into the origins of their products. With today’s supply chains, having data—essentially, a horizontal IT layer that lets people share and access data—removes the barriers of communication among stakeholders.
IoT serves as a tool to remove the barriers to collaboration between food manufacturers, food logistics businesses, restaurant and food retail chains, regulatory agencies, and the end consumer. It increases the transparency of information and helps to deliver better products throughout the food supply chain.

Get Started

Acknowledging that most food companies have limited resources, food brands can still face their efforts only on the suppliers and customers that are of the greatest concern. Often this means looking at the combination of “high-risk product” with “high-risk supplier/partner” and prioritizing that part of the supply chain. This prioritization will help food brands allocate their resources and focus their time and money on the highest risks to their customers and brand. Once they’re able to reap the benefits of a preventive food safety program, they’re better able to justify allocating additional resources to other parts of the cold chain.

While IoT, cloud monitoring and traceability technology has been around for some time, real-time data is now becoming standard. Traditionally, the cost of IoT technology and data infrastructure could be quite expensive. However, different business models like subscription are on the rise, which lower the cost of entry for new prospects and can connect a broader range of products, not only high-value goods.

Although many food brands already have some proactive food safety programs in place, it only takes one incident to lead to a major food recall—even if it isn’t your company’s product—and it can negatively impact your business.
As an industry, food brands need to continue raising the bar in terms of what is considered standard and “best practice” when building an effective, proactive food safety strategy. Utilizing best-in-class technology can ensure the delivery of safe foods to the market, prevent recalls, protect business interests, and most importantly, protect consumers.

Method Acting: Comparing Different Analytical Methods for Allergen Testing and Verification

By Gabriela Lopez-Velasco, Ph.D.

Gabriela Lopez, 3M Food Safety

Every day, food industries around the world work to comply with the food labeling directives and regulations in place to inform consumers about specific ingredients added to finished products. Of course, special attention has been placed on ensuring that product packaging clearly declares the presence of food allergens including milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soy, sesame and mustard. (Additional food allergens may also be included in other regions.)

But labeling only covers the ingredients deliberately added to foods and beverages. In reality, food manufacturers have two jobs when it comes to serving the needs of their allergic consumers:

  1. Fully understand and clearly declare the intentional presence of allergenic foods
  2. Prevent the unintended presence of allergenic foods into their product

Almost half of food recalls are the result of undeclared allergens, and often these at-fault allergens were not only undeclared but unintended. Given such, the unintended presence of allergenic foods is something that must be carefully considered when establishing an allergen control plan for a food processing facility.

How? It starts with a risk assessment process that evaluates the likelihood of unintentionally present allergens that could originate from raw materials, cross-contact contamination in equipment or tools, transport and more. Once the risks are identified, risk management strategies should then be established to control allergens in the processing plant environment.
It is necessary to validate these risk management strategies or procedures in order to demonstrate their effectiveness. After validation, those strategies or procedures should then be periodically verified to show that the allergen control plan in place is continually effective.

In several of these verification procedures it may be necessary to utilize an analytical test to determine the presence or absence of an allergenic food or to quantify its level, if present. Indeed, selecting an appropriate method to assess the presence or the level of an allergenic food is vitally important, as the information provided by the selected method will inform crucial decisions about the safety of an ingredient, equipment or product that is to be released for commercialization.

A cursory review of available methods can be daunting. There are several emerging methods and technologies for this application, including mass spectroscopy, surface plasmon resonance, biosensors and polymerase chain reaction (PCR). Each of these methods have made advancements, and some of them are already commercialized for food testing applications. However, for practical means, we will discuss those methods that are most commonly used in the food industry.

In general, there are two types of analytical methods used to determine the presence of allergenic foods: Specific and non-specific methods.

Specific tests

Specific methods can detect target proteins in foods that contain the allergenic portion of the food sample. These include immunoassays, in which specific antibodies can recognize and bind to target proteins. The format of these assays can be quantitative, such as an enzyme-linked immunosorbent assay (ELISA) that may help determine the concentration of target proteins in a food sample. Or they can be qualitative, such as a lateral flow device, which within a few minutes and with minimum sample preparation can display whether a target protein is or is not present. (Note: Some commercial formats of ELISA are also designed to obtain a qualitative result.)

To date, ELISA assays have become a method of choice for detection and quantification of proteins from food allergens by regulatory entities and inspection agencies. For the food industry, ELISA can also be used to test raw ingredients and final food products. In addition, ELISA is a valuable analytical tool to determine the concentration of proteins from allergenic foods during a cleaning validation process, as some commercial assay suppliers offer methods to determine the concentration of target proteins from swabs utilized to collect environmental samples, clean-in-place (CIP) final rinse water or purge materials utilized during dry cleaning.

ELISA methods often require the use of laboratory equipment and technical skills to be implemented. Rapid-specific methods such as immunoassays with a lateral flow format also allow detection of target specific proteins. Given their minimal sample preparation and short time-to-result, they are valuable tools for cleaning validation and routine cleaning verification, with the advantage of having a similar sensitivity to the lowest limit of quantification of an ELISA assay.

The use of a specific rapid immunoassay provides a presence/absence result that determines whether equipment, surfaces or utensils have been cleaned to a point where proteins from allergenic foods are indiscernible at a certain limit of detection. Thus, equipment can be used to process a product that should not contain a food allergen. Some commercial rapid immunoassays offer protocols to use this type of test in raw materials and final product. This allows food producers to analyze foods and ingredients for the absence of a food allergen with minimum laboratory infrastructure and enables in-house testing of this type of sample. This feature may be a useful rapid verification tool to analyze final product that has been processed shortly after the first production run following an equipment cleaning.

Non-Specific Tests

While non-specific testing isn’t typically the best option for a cleaning validation study, these tests may be used for routine cleaning verification. Examples of non-specific tests include total protein or ATP tests.

Tests that determine total protein are often based on a colorimetric reaction. For example, commercial products utilize a swab format that, after being used to survey a defined area, is placed in a solution that will result in a color change if protein is detected. The rationale is that if protein is not detected, it may be assumed that proteins from allergenic foods were removed during cleaning. However, when total protein is utilized for routine verification, it is important to consider that the sensitivity of protein swabs may differ from the sensitivity of specific immunoassays. Consequently, highly sensitive protein swabs should be selected when feasible.

ATP swab tests are also commonly utilized by the food industry as a non-specific tool for hygiene monitoring and cleaning verification. However, the correlation between ATP and protein is not always consistent. Because the ATP present in living somatic cells varies with the food type, ATP should not be considered as a direct marker to assess the removal of allergenic food residues after cleaning. Instead, an analytical test designed for the detection of proteins should be used alongside ATP swabs to assess hygiene and to assess removal of allergenic foods.

Factors for Using One Test Versus Another

For routine testing, the choice of using a specific or a non-specific analytical method will depend on various factors including the type of product, the number of allergenic ingredients utilized for one production line, whether a quantitative result is required for a particular sample or final product, and, possibly, the budget that is available for testing. In any case, it is important that when performing a cleaning validation study, the method used for routine testing also be included to demonstrate that it will effectively reflect the presence of an allergenic food residue.

Specific rapid methods for verification are preferable because they enable direct monitoring of the undesirable presence of allergenic foods. For example, they can be utilized in conjunction with a non-specific protein swab and, based on the sampling plan, specific tests can then be used periodically (weekly) for sites identified as high-risk because they may be harder to clean than other surfaces. In addition, non-specific protein swabs can be used after every production changeover for all sites previously defined in a sampling plan. These and any other scenarios should be discussed while developing an allergen control plan, and the advantages and risks of selecting any method(s) should be evaluated.

As with all analytical methods, commercial suppliers will perform validation of the methods they offer to ensure the method is suitable for testing a particular analyte. However, given the great diversity of food products, different sanitizers and chemicals used in the food industry, and the various processes to which a food is subjected during manufacturing, it is unlikely that commercial methods have been exhaustively tested. Thus, it is always important to ensure that the method is fit-for-purpose and to verify that it will recover or detect the allergen residues of interest at a defined level.

Notable Outbreaks and Recalls of 2018

By Maria Fontanazza

sad face

As stated by CDC’s John Besser, Ph.D. last month at the Food Safety Consortium, “It’s been quite a year for outbreaks.” Here’s a not-so-fond look back at some of the noteworthy outbreaks and recalls of 2018.

Romaine Lettuce –E.coli O157:H7

2018 was not a good year for romaine lettuce. In the spring, a deadly multistate outbreak of E.coli O157:H7 was linked to romaine lettuce that came from the Yuma, Arizona growing region. “We knew right away that this was going to get bad and that it would get bad quickly,” said Matthew Wise, deputy branch chief for outbreak response at the Outbreak Response and Prevention Branch of the CDC at the 2018 Food Safety Consortium. Although the CDC declared the outbreak over at the end of June, the total number of illnesses had reached 210, with five deaths.

Then in November it was revealed that contaminated lettuce was coming from growing regions in northern and central California. According to the latest update from FDA, there have been 59 reported illnesses, with 23 hospitalizations, across 16 states. No deaths have been reported. Earlier this month Adam Bros Farming, Inc. recalled red leaf lettuce, green leaf lettuce and cauliflower, because it may have come into contact with water from the reservoir where the E. coli outbreak strain was found.

Raw Beef Products – Salmonella

At the beginning of the month, JBS Tolleson, Inc. expanded a recall of its non-intact raw beef products due to concerns of contamination with Salmonella Newport. More than 12 million pounds of product have been recalled. The latest CDC update put the reported case count at 333, with 91 hospitalizations across 28 states.

Shell Eggs – Salmonella

In April, Rose Acre Farms recalled more than 206 million eggs after FDA testing determined that eggs produced from the company’s farm were connected to 22 cases of Salmonella Braenderup infections. A total of 45 cases were reported across 10 states, with 11 hospitalizations, according to the CDC.

Pre-cut Melon – Salmonella

In June Caito Foods recalled its pre-cut melon products after a multi-state outbreak of Salmonella Adelaide infections were traced back to the products. A total of 77 cases across nine states, with 36 hospitalizations, were reported.

Vegetable Trays – Cyclospora

In July, Del Monte recalled its vegetable trays that contained broccoli, cauliflower, carrots and dill dip following confirmed cases of cyclosporiasis in people who consumed the products. The CDC declared the outbreak over in September, with a final case count at 250 people across four states.

Salad Mix – Cyclospora

Fresh Express salad mix served at McDonalds was linked to a multistate outbreak of cyclosporiasus. The outbreak was declared over in September, with the final illness count at 511, and 24 hospitalizations.

Raw Turkey – Salmonella

Just before Thanksgiving an outbreak of Salmonella linked to raw turkey products was announced. Jennie-O Turkey Store Sales recalled more than 255,000 pounds of raw ground turkey products, however the CDC has not identified a single, common supplier that can account for this outbreak. As of the agency’s latest update on December 21, 216 cases have been reported across 38 states. The outbreak is responsible for 84 hospitalizations and one death.

Honey Smacks Cereal – Salmonella

The early summer outbreak of Salmonella Mbandaka linked to Kellogg’s Honey Smacks cereal got a lot of press, and it didn’t help that even though the company recalled the product, many retailers continued to keep the cereal on their shelves. The last illness onset was reported at the end of August. A total of 135 people were reported ill, with 34 hospitalizations.

Duncan Hines Cake Mix – Salmonella

The company recalled four varieties of its cake mixes after a retail sample tested positive for Salmonella Agbeni.

Johnston County Hams – Listeria monocytogenes

The company recalled more than 89,000 pounds of RTE deli loaf ham products over concerns of adulteration with Listeria monocytogenes.

Other outbreaks involving Salmonella this year included dried and frozen coconut, pasta salad, chicken salad and raw sprouts.
