As a precautionary measure, ALDI is voluntarily recalling assorted peaches received from its supplier, Wawona Packing Company, due to possible Salmonella contamination.

–UPDATE AUGUST 31, 2020 — Prima Wawona has recalled bagged, bulk and loose peaches that were distributed nationwide to retailers that include ALDI, Food Lion, Hannaford, Kroger, Target, Walmart and Wegmans. As of August 28, the CDC reported the outbreak of Salmonella infections reached 78 cases across 12 states.

In addition, the recall of Prima Wawona peaches has extended to Canada, Singapore and New Zealand. FDA states that the products may have been shipped to Australia, Canada, China, Costa Rica, Ecuador, El Salvador, Guatamala, Honduras, Mexico, Panama, the Philippines, Singapore, Taiwan and the United Arab Emirates.

–END UPDATE–

Do not eat, sell or serve Wawona-brand bagged peaches from ALDI stores, says the FDA. ALDI issued a voluntary recall of two-pound clear plastic bags of peaches from Wawona Packing Company, LLC following a multistate outbreak of Salmonella Enteritidis that has been linked to the product. The peaches were sold in ALDI stores from June 1 until present, and as of August 19, the CDC reported 68 cases of Salmonella infections across nine states, with 14 hospitalizations. No deaths have been reported

“FDA’s traceback investigation is ongoing to identify the source of this outbreak and to determine if potentially contaminated product has been shipped to additional retailers,” the agency stated in an investigation update.

Learn more about food safety supply chain management & traceability during the 2020 Food Safety Consortium Virtual Conference SeriesThe FDA and CDC have been investigating a multistate outbreak of Cyclospora involving bagged salads from Fresh Express since June. Although the products were recalled and should no longer be available in retail locations, the CDC continues to report more cases. As of August 12, 2020, the CDC counted 690 people with laboratory-confirmed Cyclospora infections throughout 13 states. Thirty-seven people have been hospitalized, and no deaths have been reported.

As the FDA conducted its traceback investigation to find the source of the outbreak linked to the Fresh Express products, the agency was able to identify several farms. It analyzed water samples from two public access points along a regional water management canal (C-23) west of Port St. Lucie, Florida. Using the FDA’s validated testing method, the samples tested positive for Cyclospora cayetanensis. However, it is important to note that the Cyclospora found might not be a direct match to the pathogen found in the clinical cases.

According to FDA: “Given the emerging nature of genetic typing methodologies for this parasite, the FDA has been unable to determine if the Cyclospora detected in the canal is a genetic match to the clinical cases, therefore, there is currently not enough evidence to conclusively determine the cause of this outbreak. Nevertheless, the current state of the investigation helps advance what we know about Cyclospora and offers important clues to inform future preventive measures.”

The agency’s traceback investigation is complete, but the cause or source of the outbreak has not been determined. The investigation also revealed that carrots are no longer of interest at as part of the outbreak, but red cabbage and iceberg lettuce are still being investigated. FDA is also working with Florida and the area’s local water district to learn more about the source of Cyclospora in the canal.

–UPDATE: August 10, 2020 —

Last week USDA’s FSIS issued a public health alert concerning ready-to-eat meat and poultry products that contain the onions recalled by Thomson International, Inc. (see below news brief). The products have been distributed by retail establishments that include Walmart, Kroger, HEB and Amana Meat Shop & Smokehouse. The USDA has made available the full list of products subject to the public health alert.

–END UPDATE–

A multistate outbreak of Salmonella Newport has been traced back to red onions from Thomson International, Inc. a company based in Bakersfield, CA. As of July 31, 396 illnesses were reported in the United States, with 59 hospitalized across 34 states. In Canada, 120 cases have been confirmed, according to the Public Health Agency of Canada.

As a result, Thomson International is recalling all varieties of its onions (red, white, yellow and sweet) that “could have come in contact with potentially contaminated red onions”, according to an FDA alert.

The FDA, CDC, state and local agencies, as well as the Public Health Agency of Canada are investigating the outbreak. FDA recommends that consumers, restaurants and retailers refrain from eating, selling or serving any onions from Thomson International. The agency also states that any surfaces, containers or storage areas that may have come into contact with these products be cleaned and sanitized.

Q&A: Pandemic Puts Worker Health & Safety, Leadership Skills and Business Adaptability at Forefront

By Maria Fontanazza

Jennifer van de Ligt, Food Protection and Defense Institute, University of Minnesota

Issues with the health of frontline workers, supply chain disruptions, and changes in consumer behavior are just a few vulnerabilities that the food industry is experiencing as a result of COVID-19. Food Safety Tech recently had a conversation with Jennifer van de Ligt, Ph.D., director of the University of Minnesota Integrated Food Systems Leadership Program and Food Protection and Defense Institute about the hurdles that the industry is experiencing and where we go from here.

Food Safety Tech: What challenges is the food system facing in light of the COVID-19 pandemic? Where are the vulnerabilities?

Jennifer van de Ligt, Ph.D.: The food system is facing primary, secondary and tertiary challenges right now. I see two main drivers as disruptors as a result of COVID-19. The health and safety of employees is the first primary driver. As COVID-19 has more broadly spread through the U.S., ensuring the health and safety of employees in the food system has become essential; however, the pandemic has shown us the food system has struggled with that.

The other big primary challenge facing the food system has been the swift change in consumer behavior. Pre-COVID-19, nearly half of food was consumed away from home. When restaurants closed, and stay-at-home orders were in place, it put extreme amounts of pressure on our food retail segment, causing supply and demand issues.

Regarding the health and safety of employees: We’ve seen meat processing struggle with production demands because the health of their employees has been impacted by the virus. In mid-April, the beef and pork capacity in this country went down by over 40%. They are making great improvements and are approaching normal harvest capacity range for both [beef and pork production]. Meat cuts being produced are slightly different than normal, as this part of the meat plants are very labor intensive. This has really highlighted the need to make sure that we keep the health and safety of our food system employees front and center.

During the 2020 Food Safety Consortium Virtual Conference Series, Jennifer Van de Ligt will participate in a panel discussion on November 5 about Professional Development and Women in Food Safety | Register Now Now that the meat supply chain is beginning to recover, we’re also beginning to see increasing effects on non-meat supply manufacturing. This isn’t isolated to food manufacturing; as we experience broader community spread, COVID-19 will impact all aspects of our food system.

On consumer behavior: As consumers shifted to food retail, immense pressure was quickly put on our food supply chain logistics, manufacturing timing and processes, the speed to warehouses and delivery, etc.

One example that demonstrates a challenge in manufacturing and consumer demand is the difference in volumes for food services versus retail. I like to use the example of shredded cheese. At a grocery store, you’ll find a one-pound pack, but shredded cheese in food service might be in a 10-pound bag. There are not a lot of consumers who want to buy a 10-pound bag of shredded cheese. Well, why can’t cheese manufacturers just package bulk product into one-pound packs? There are several reasons that don’t allow producers to pivot quickly: They may not have the machinery or packaging to do that. Also, changing packaging from food service to retail requires different labels and regulatory approvals. Examples like this led to many of the spot outages consumers found in grocery stores. In the produce sector, it led to produce being plowed under in fields because they didn’t have the distribution channels to go into retail instead of into food service.

In the Integrated Food System Leadership (IFSL) program, we’ve recently discussed food equity and food injustice as a result of COVID-19. As food retail became stressed and unemployment increased, we saw a huge demand for our food assistance networks. Because food retail is one of the primary contributors to the food assistance networks, there wasn’t enough volume being donated. In addition, food service foods are not appropriately packaged to go into the food assistance networks and food banks, similar to the issue in moving to food retail. This led to tremendous pressure and innovative solutions to source and distribute food to a newly vulnerable population.

As we look ahead into the coming months, many of the vulnerabilities in the food system will be the same. We have to continuously monitor the health and safety of our employees to keep our food system as a whole functional. There’s a growing recognition that our primary agriculture workers are also at risk—the people in fields harvesting and planting. There are many groups providing recommendations on how to protect agriculture employees and communities where they work and reside.

We’ll see continued adaptation in the food system to the new reality of how restaurants and food service engage with their consumers with the shift in behavior to limited restaurant dining and increases in online ordering.

FST: In what areas do food manufacturers, processors or growers need to adapt moving forward in order to thrive?

Van de Ligt: There are several. First, I think this crisis has really brought worker health and welfare to the forefront, and there will be more emphasis on the essentiality of food system workers. They were previously a behind-the-scenes workforce. The issue of worker health and welfare is going to accelerate in many industries, but I also see a push to more automation. The human workforce is necessary, and people do a really wonderful job, but are there areas that might benefit from automation? I think those go hand in hand.

I also think the global food system needs to rethink how it remains resilient. In the past, there’s been a focus on resilience and efficiency through economy of scale. That still exists and may look different moving forward. Using the meat industry as an example, that economy of scale was also its biggest weakness that had gone unrecognized. Going forward, I think there are many companies that are going to consider alternative supply chains. Should multiple, smaller plants be utilized instead of one large plant to provide a more resilient framework for production? Other companies are going to think about installing equipment or processing lines that could more quickly pivot between food service and food retail. There’s also a huge opportunity now for local and smaller markets to really make an impact as people look for alternative supply chains and sources. We found that many of the local food markets and co-ops, especially those that provided into food service, pivoted pretty quickly to pop-up online marketplaces to provide food direct to consumer. I think we’ll see that trend increase as well.

In order to feed billions of people worldwide, it’s essential that the food industry take a broader systems approach versus the siloed approach path we’ve been using. The pandemic has highlighted how the food system is an intricately functioning balance and requires collaboration. Our food system will only be able to move forward faster with less disruption when we have food system leaders who understand the intricacies and the ripple effects of the challenges we face. Leaders who understand the impacts of decisions outside of their sphere will be essential to plan for impacts from natural disasters, another pandemic, etc.—and to create a more responsive and resilient food system in the future.

FST: Where does this leave folks who are either beginning or rising in their careers in food safety? Do you think the pandemic has changed food safety careers as they’ve historically functioned?

Van de Ligt: I like to say that ‘what got us here is not going to get us there.’ In general, if you think about where food safety careers have been in the past, the roles have been all about consistency, understanding regulations, making sure we do everything precisely right all of the time so we don’t have a food safety outbreak.

The focus on doing things precisely right all of the time will absolutely continue. What I think will shift is the need for food safety professionals to think more broadly than just the regulations that are required for compliance. Food safety professionals need to understand more about the system that is happening outside their facility; the impact of their work going backwards and forwards in the supply chain.

How things have worked historically in a food safety role has been having a consistent supplier network that provides the same type of product every time; you know what to expect, how to produce and distribute safe food for the customers you serve. In a situation like COVID-19, because of the disruptions from farm to fork, the suppliers you need to work with may be different and you need to quickly make decisions spontaneously as supply shifts. Having the knowledge and skills to navigate changes is essential to ensure the quality and safety of your product.

A highly technical focus that many professionals have when they start their career is often too narrow and won’t be enough for emerging food system leaders. Leadership skills are vital as well. In the IFSL program we teach food system professionals how to explore proactive viewpoints, not just managing people or responsibilities. Managers make sure things are done things correctly; leaders make sure we do the right thing. In order to learn how to do the right thing, we teach skills and tools on how to navigate uncertainty; practicing active listening, constructive feedback; and understanding the concerns of a supplier or customer are examples.

We emphasize and teach in the IFSL program that food system professionals and leaders need to be much more proactive. This means equipping them with the food system knowledge and leadership skills so they can predict and prepare for how decisions affect upstream and downstream. Having a broader viewpoint is critical to adaptivity, which will build resilience and help limit disruption.

Coronavirus, COVID-19

View the complimentary webinar, “Instant Replay & Update: Is Your Plant COVID-19 Safe?”A lawsuit filed yesterday against OSHA alleges that the agency did not protect meat packing plant workers during the COVID-19 pandemic. Three workers from Pennsylvania-based Maid-Rite Specialty Foods are suing OSHA for putting workers in “imminent danger” as a result of hazardous working conditions, according to The Washington Post. The lawsuit stated that Maid-Rite did not:

  • Implement social distancing measures on the processing lines
  • Provide acceptable personal protective equipment
  • Address sick workers safely by not separating them
  • Tell all workers who may have been in close contact with sick workers

Maid Rite is also accused of incentivizing sick employees to report to work with bonuses.

Both OSHA and Maid Rite have not yet commented on the lawsuit as of yet.

For months, COVID-19 outbreaks at meat and poultry processing plants have been a problem, with more than 11,000 infections being reported.

Coronavirus and Food Security

The novel coronavirus (COVID-19) has been quickly spreading across the globe, which triggered most affected countries to officially declare a state of public health emergency. The World Health Organization (WHO) has labeled this rather fast outbreak as pandemic. Food companies were urged to apply proper hygiene practices such as regular handwashing and surface cleaning to keep the risk of contagion at its lowest level.1 At the moment, there are many ongoing clinical trials evaluating potential treatments for COVID-19 but no specific vaccine or medicine have been publicly made available, as of this writing.

COVID-19 belongs to a family of viruses that cause respiratory issues and can be passed on directly through contact with an infected person’s body fluids (i.e, cough or sneeze discharge) and indirectly, through contact with contaminated surfaces.2 But can the virus be transmitted through edible goods?

Coronavirus Transmission through Food
According to the CDC, there is no current indication to support the transmission of COVID-19 through food since, in general, it needs a living host on which to grow. However, sharing food and beverages, especially in public places, is discouraged. Moreover, good food safety practices are highly recommended, including refrigerating, keeping raw and cooked goods separated and heating food at suitable temperature (around 75 ̊ C).3

If the consumed food is hypothetically contaminated with the virus, the stomach acid (due to its acidic nature) will immediately inactivate it. In addition, COVID-19 cannot affect the body internally via the intestines. One rare exception to the previous statement occurs when the virus gets in contact with a specific type of respiratory cells.

According to food safety experts, foodborne illnesses are generally caused by bacterial cells that have the ability to grow in food and multiply rapidly within a short amount of time. On the other hand, viruses are dormant particles floating around living cells; only when they successfully breaks into the aforementioned cells, the multiplication process can take place.1,3

General Food Safety Advice for Food Businesses

Food manufacturers must follow good hygiene and safety practices to help ensure the consistent quality and safety of their products:4,5,6

  • Purchase raw material from reputable sources
  • Cook food thoroughly and maintain safe holding temperatures
  • Clean and sanitize surfaces (such as cooking boards, refrigerators handles, etc.) and equipment
  • Properly train staff in taking extreme hygiene measures
  • Employees showing signs of infectious illness must not attend work
  • Implement appropriate risk management strategies (e.g,. encourage social distancing and endorse online meetings when applicable)
  • Number of staff in a kitchen or food preparation area should be kept to a bare minimum
  • Space out workstations and food preparation areas, when possible

Revolutionary Rapid Testing for Listeria Monocytogenes and Salmonella

The Golden Age of Bacteriology: Discovering the Unknown in a Farm-to-Market Food Supply.

The last quarter of the 19th Century was both horrific and exciting. The world had just emerged from four decades of epidemic in cholera, typhoid fever and other enteric diseases for which no cause was known. Thus, the great scientific minds of Europe sought to find understanding. Robert Koch integrated Pasteur’s Germ Theory in 1861 with the high technology of the day: Mathematical optics and the first industrialized compound microscopes (Siebert, Leiss, 1877), heterocycle chemistry, high-purity solvents (i.e., formaldehyde), availability of engineered glass suitable as microscope slides and precision-molded parts such as tubes and plates in 1877, and industrialized agar production from seaweed in Japan in 1860. The enduring fruit of Koch’s technology integration tour de force is well known: Dye staining of bacteria for sub-micron microscopy, the invention of 13 cm x 1 cm culture tubes and the invention of the “Petri” dish coupled to agar-enriched culture media. Those technologies not only launched “The Golden Age of Bacteriology” but also guided the entire field of analytical microbiology for two lifetimes, becoming bedrock of 20th Century food safety regulation (the Federal Food, Drug and Cosmetic Act in 1938) and well into the 21st century with FSMA.

Learn more about technologies in food safety testing at the Food Labs / Cannabis Labs Conference | June 2–4, 2020 | Register now!Blockchain Microbiology: Managing the Known in an International Food Supply Chain.

If Koch were to reappear in 2020 and were presented with a manual of technical microbiology, he would have little difficulty recognizing the current practice of cell fixation, staining and microscopy, or the SOPs associated with fluid phase enrichment culture and agar plate culture on glass dishes (still named after his lab assistant). The point to be made is that the analytical plate culture technology developed by Koch was game changing then, in the “farm-to-market” supply chain in Koch’s hometown of Berlin. But today, plate culture still takes about 24 to 72 hours for broad class indicator identification and 48 to 96 hours for limited species level identification of common pathogens. In 1880, life was slow and that much time was needed to travel by train from Paris to Berlin. In 2020, that is the time needed to ship food to Berlin from any place on earth. While more rapid tests have been developed such as the ATP assay, they lack the speciation and analytical confidence necessary to provide actionable information to food safety professionals.

It can be argued that leading up to 2020, there has been an significant paradigm shift in the understanding of microbiology (genetics, systems based understanding of microbial function), which can now be coupled to new Third Industrial Age technologies, to make the 2020 international food supply chain safer.

We Are Not in 1880 Anymore: The Time has Come to Move Food Safety Testing into the 21st Century.

Each year, there are more than 48 million illnesses in the United States due to contaminated food.1 These illnesses place a heavy burden on consumers, food manufacturers, healthcare, and other ancillary parties, resulting in more than $75 billion in cost for the United States alone.2 This figure, while seemingly staggering, may increase in future years as reporting continues to increase. For Salmonella related illnesses alone, an estimated 97% of cases go unreported and Listeria monocytogenes is estimated to cause about 1,600 illnesses each year in the United States with more than 1,500 related hospitalizations and 260 related deaths.1,3 As reporting increases, food producers and regulatory bodies will feel an increased need to surveil all aspects of food production, from soil and air, to final product and packaging. The current standards for pathogenic agriculture and environmental testing, culture-based methods, qPCR and ATP assays are not able to meet the rapid, multiplexed and specificity required to meet the current and future demands of the industry.

At the DNA level, single cell level by PCR, high throughput sequencing, and microarrays provide the ability to identify multiple microbes in less than 24 hours with high levels of sensitivity and specificity (see Figure 1). With unique sample prep methods that obviate enrichment, DNA extraction and purification, these technologies will continue to rapidly reduce total test turnaround times into the single digit hours while simultaneously reducing the costs per test within the economics window of the food safety testing world. There are still growing pains as the industry begins to accept these new molecular approaches to microbiology such as advanced training, novel technology and integrated software analysis.

It is easy to envision that the digital data obtained from DNA-based microbial testing could become the next generation gold standard as a “system parameter” to the food supply chain. Imagine for instance that at time of shipping of a container, a data vector would be produced (i.e., time stamp out, location out, invoice, Listeria Speciation and/or Serovar discrimination, Salmonella Speciation and/or Serovar discrimination, refer toFigure 1) where the added microbial data would be treated as another important digital attribute of the load. Though it may seem far-fetched, such early prototyping through the CDC and USDA has already begun at sites in the U.S. trucking industry, based on DNA microarray and sequencing based microbial testing.

Given that “Third Industrial Revolution” technology can now be used to make microbial detection fast, digital, internet enabled and culture free, we argue here that molecular testing of the food chain (DNA or protein based) should, as soon as possible, be developed and validated to replace culture based analysis.

Broad Microbial Detection

E. Coli Outbreaks Linked to Salinas-Grown Romaine Lettuce Over, Deputy Commissioner Yiannas Releases Statement

By Food Safety Tech Staff
No Comments
FDA

Yesterday the CDC reported that the E.coli outbreak linked to romaine lettuce grown in the Salinas, CA growing region is over. The contaminated lettuce should no longer be available, and FDA states that consumers do not need to avoid romaine lettuce from Salinas. The agency will continue its investigation into the potential factors and sources that led to the outbreak.

The FDA did identify a common grower link to the E.coli O157:H7 contamination as a result of its traceback investigation. However, a statement released yesterday by FDA Deputy Commissioner for Food Policy and Response Frank Yiannas points out that “this grower does not explain all of the illnesses seen in these outbreaks.”

To be specific, the FDA, CDC and other public health agencies were tracking three outbreaks involving three separate strains of E.coli O157:H7 linked to romaine lettuce. During the course of the investigation FDA, CDC, the California Department of Food and Agriculture and the California Department of Public Health conducted sampling of the water, soil and compost of several of the fields in the lower Salinas Valley that were connected to the outbreak. “So far, sample results have come back negative for all of the three outbreak strains of E. coli O157:H7. However, we did find a strain of E. coli that is unrelated to any illnesses in a soil sample taken near a run-off point in a buffer zone between a field where product was harvested and where cattle are known to occasionally graze,” Yiannas said in the agency statement. “This could be an important clue that will be further examined as our investigation continues. However, this clue does not explain the illnesses seen in these outbreaks.”

Finding the contamination source(s) is critical, as it will aid romaine growers in putting safeguards in place to help prevent future contamination.

As for the final case count (with last illness onset on December 21, 2019) of this outbreak, there were 167 total illnesses and 85 hospitalizations across the United States. No deaths were reported.
