How to Prevent Foodborne Pathogens in Your Production Plant

Foodborne pathogens, such as bacteria and parasites in consumable goods, can result in illnesses and deaths, wreaking havoc on residents of states and countries. The companies at fault often face severe damage to their reputation as people fear that continuing to do business with a brand is not safe. Moreover, if the affected enterprises do not take decisive steps to prevent the problem from happening again, they may receive substantial fines or closure orders.

Statistics from the U.S. federal government indicate that there are approximately 48 million cases of foodborne illnesses in the American food supply each year. Fortunately, there are proven steps that production plant managers can take to minimize the risk of foodborne pathogens. Being familiar with the preventative measures, and taking steps to implement them prevents catastrophes.

Engage with Suppliers about Their Efforts to Kill or Reduce Foodborne Pathogens

Foodborne pathogens can enter a production plant on items like fresh produce received from farm suppliers. Agricultural professionals commonly use chlorine to decontaminate goods before shipping them. However, researchers used a chlorine solution on spinach leaves to assess its effectiveness in killing common types of bacteria. The team discovered that, even after chlorine exposure, some bacteria remained viable but undetectable by industrial methods.

Foodborne pathogens can originate at farms for other reasons, too. Failing to take the proper precautions during animal slaughter can introduce contaminants into meats that end up in food production facilities. Water impurities can also pose dangers.

All production plants should regularly communicate with suppliers about the actions they take against foodborne pathogens. Food safety is a collective effort. Practicing it means following all current guidance, plus updating methods if new research justifies doing so. If suppliers resist doing what’s in their power to stop foodborne pathogens, they must realize they’re at risk for severing profitable relationships with production plants that need raw goods.

Consider Using Sensors to Maintain Safe Conditions

The Internet of Things (IoT) encompasses a massive assortment of connected products that benefit industries and consumers alike. One practical solution to enhance food safety in a production plant involves installing smart sensors that detect characteristics that humans may miss.

For example, the USDA published a temperature safety chart that explains what to do with food after a power outage. Most items that people typically keep in refrigerators become dangerous to eat if kept above 40o F for more than two hours.

Food production plants typically have resources like backup power to assist if outages occur. But, imagine a cooler that appears to work as expected but has an internal malfunction that keeps the contents at incorrect temperatures. IoT sensors can help production plant staff members become immediately aware of such issues. Without that kind of information, they risk sending spoiled food into the marketplace and getting people sick.

Researchers also developed a sensor-equipped device that detects the effectiveness of hand washing efforts. In a pilot program involving 20 locations, contamination rates decreased by 60% over a month. Most restrooms at food preparation facilities remind people to wash their hands before returning to work. What if a person takes that action, but not thoroughly enough? Specialty sensors could reduce that chance.

Install Germicidal Ultraviolet Lights

With much of the world on lockdown due to the COVID-19 pandemic, many people want to know if germicidal ultraviolet lights could kill the novel coronavirus. Researchers lack enough information to answer that question definitively. They do know, however, that germicidal ultraviolet lights kill up to 99.99% of bacteria and pathogens.

Plus, these lights are particularly useful in food production because they get the job done without harsh chemicals that could make products unsafe. Ultraviolet lights can damage the skin and eyes, so you must only run them when there are no humans in the room. However, it’s immediately safe to enter the environment after switching the lights off.

These specialized light sources do not eliminate the need for other food safety measures. Think about implementing them as another safeguard against adverse consequences.

Teach Workers about Safe Practices

Food contamination risks exist at numerous points along the supply chain. Mishandling is a major culprit that could make several parties partially responsible for a foodborne pathogen problem. For example, if a person does not wear the proper gear when handling food or stores items intended for raw consumption in places where meat juices touch them, either of those things and many others could cause issues with foodborne pathogens.

As you inform employees about which procedures to take to manage the risks, emphasize that everyone has an essential role to play in keeping products free from contaminants. If workers make ready-to-eat foods, such as packaged sandwiches, ensure they understand how to avoid the cross-contamination that happens when reusing cutting boards or utensils without washing them first.

The FDA requires domestic and foreign food facilities to analyze and mitigate risks. Employee training is not the sole aspect of staying in compliance, but it’s a major component. If a person makes a mistake due to improper or nonexistent training, that blunder could have significant financial ramifications for a food production facility.

Widely cited statistics indicate that food recall costs average more than $10 million, which is a staggering figure in itself. It doesn’t include litigation costs incurred when affected individuals and their loved ones sue companies, or the expenses associated with efforts to rejuvenate a brand and restore consumer confidence after people decide to take their business elsewhere.

Ensuring that workers receive the necessary training may be especially tricky if a human resources professional hires a large batch of temporary employees to assist with rising seasonal demands. If a higher-up tells them that time is of the essence and the new workers must be ready to assume their roles on the factory floor as soon as possible, training may get overlooked. When that happens, the outcomes could be devastating. Efficiency should never get prioritized over safety.

Stay Abreast of Emerging Risks

Besides doing your part to curb well-known threats that could introduce foodborne pathogens, spend time learning about new problems that you may not have dealt with before.

For example, scientists have not confirmed the origin of COVID-19. However, since early evidence suggested live animal sales and consumption may have played key roles, Chinese officials cracked down on the wildlife trade and imposed new restrictions on what was largely an unregulated sector cloaked in secrecy.

Much remains unknown about COVID-19, and it’s but one virus for food producers to stay aware of and track as developments occur. The ongoing pandemic is a sobering reminder not to blame specific groups or ethnicities, and to avoid jumping to hasty conclusions. It’s good practice to dedicate yourself to learning about any production risks that could introduce foodborne pathogens. Read reputable sources, and don’t make unfounded assumptions.

A Collective and Constant Effort

There is no single way to combat all sources of foodborne pathogens. Instead, anyone involved in food production or supply must work diligently together and know that their obligation to prevent issues never ceases.

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

By Food Safety Tech Staff

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.

Using whole genome sequencing (WGS), FDA has confirmed 96 illnesses in 11 states that were caused by Salmonella Javiana. Thus far, traceback evidence indicates that a fruit mix from New Jersey-based Tailor Cut Produce is the possible source of the outbreak.

FDA provided its latest update about the ongoing investigation today: Of the 96 illnesses, 27 have been hospitalized, and no deaths have been reported. The highest number of illnesses have been reported in Delaware (39), Pennsylvania (34) and New Jersey (12). The agency stated its inspection at Tailor Cut Produce continues and it is collecting records to support a traceback investigation.

Tailor Cut Produce recalled the Fruit Luau fruit mix earlier in December, along with its cut honeydew, cantaloupe and pineapple products.

Lettuce

In the latest FDA update about the E. coli O157:H7 outbreak involving romaine lettuce, the agency has stated that consumers should not eat romaine lettuce that has been harvested from Salinas, California. Traceback investigations related to three different E. coli outbreaks (three different strains, all of which involve romaine lettuce) have pointed to a common grower located in Salinas. Frank Yiannas, deputy commissioner for food policy and response, called the identification of a common grower a “notable development” but also stated in a press announcement, “Because of the expansive nature of these outbreaks, our investigation remains a complicated work in progress, and it is too soon to draw definitive conclusions.”

FDA, CDC and California partners have sent out a team to conduct new investigations at ranches used by the grower as part of the process in finding the contamination source, according to an FDA update.

Thus far, 102 illnesses have been reported across 23 states, with 58 hospitalizations. No deaths have been reported. The last illness onset was reported on November 18.

Thus far Swedesboro, NJ-based Missa Bay, LLC has recalled more than 75,000 pounds of salad products because of a lettuce ingredient that might be contaminated with E. coli O157:H7. This lettuce was also found to be in packaged salad that the Maryland Department of Health said contained E. coli.

FDA states that thus far lettuce grown indoors has not been indicated in the outbreak.

The Value of a One Percent Improvement

During the past year, the headlines have been filled with stories of foodborne illness, product recalls, and consumers becoming sick from tainted food. In a Q&A with Food Safety Tech, Sean O’Leary, CEO at FoodLogiQ, talks food safety, traceability, and how small percentages can translate into big victories for the food industry and for the people they serve.

Food Safety Tech: From your perspective, what is the current sentiment of consumers with regard to food safety?

Sean O’Leary: Over the last few years, the consumer mindset has changed about food in general. We’ve watched fad diets come and go; however, the interest in healthy ingredients and the concern about where food comes from has graduated from a passing trend to a full shift into the public consciousness. Consumers are much more discerning about what they eat; they also demand to know where their food comes from, how it was produced, and how it got to their table. We are living in the age of transparency, and consumer expectations are high.

And who can blame them? CDC statistics tell us that approximately 48 million people get sick every year from foodborne illnesses—and that’s just in the United States; 128,000 of them end up in the hospital. When a person is admitted to the hospital, it affects more than just that one individual. If the patient is the sole breadwinner of their family, their illness affects the entire family. If the person who gets sick is a child, there can be long-term consequences that trickle down to his or her whole community. And when you consider that 3,000 people die every year from foodborne illness—that’s one 9/11 every year. That’s unacceptable, because this is a preventable issue, and unfortunately, these illnesses are an underreported public health problem.

My challenge to the food industry is simple: What if we made just a 1% improvement in the number of cases of foodborne illness? That seems like such a small percentage, but when you do that math, that’s 480,000 people who don’t get sick this year; 1,280 people who aren’t admitted to the hospital; and 30 people who don’t die. Those are significant numbers.

Sean O'Leary, FoodLogiQ
Sean O’Leary joined FoodLogiQ as CEO in January 2019 with more than 25 years of experience in the technology industry.

FST: To help shed additional light on this subject, FoodLogiQ conducted a national survey to tap into how U.S. consumers feel about issues related to food transparency. What did you learn from those consumer responses?

O’Leary: We polled more than 2,000 people to gauge their sentiment around food traceability and their expectations for food companies regarding foodborne illness and product recalls. The survey also posed questions around consumer preferences regarding their food sources and how they are identified on food labels and menus. The results were enlightening, to say the least.

We learned that a brand or restaurant will pay a high price in terms of customer loyalty if they experience a food recall due to consumer illness. And those customers have some strong opinions regarding how quickly the brand or restaurant should address a food safety issue.

  • 35% of survey respondents told us they would avoid an affected brand or restaurant for a few months, and maybe they would return after the issue had been resolved. Meanwhile, nearly 25% admitted they would never use the brand or visit the restaurant again.
  • Of the respondents who say they care about the quality of the food they eat, 55% say they expect a recall to be executed within 24 to 48 hours.

In reality, it sometimes takes weeks for a product to be pulled from the store or restaurant. This is frequently due to communication issues, since everyone along the supply chain—the grower, supplier, packing and distribution centers, corporate office, and the retailer or restaurant—all must be notified, and a recall plan must be set in motion. Unfortunately, that communication process takes time. When that communication takes place via email or by phone call, the people responsible for pulling product may not have the information they need or may have received misinformation. This can result in lag time, and potentially unsafe product can still get into the hands of consumers.

The faster a food company can address a recall situation and return to business as usual, the faster customers will come back. But comprehensive supply chain transparency is needed to be able to make swift, accurate decisions during this time of crisis. By having a robust end-to-end traceability program and technology that provides real-time data and visibility, companies facing a recall can isolate and surgically withdraw the tainted product out of the supply chain without recalling more items than necessary. That limits the disruption and the waste of good food, which saves the company money.

FST: You recently attended the FDA’s “A New Era of Smarter Food Safety” public meeting in Maryland. What do you think this new campaign will mean for the food industry?

O’Leary: FoodLogiQ was honored to have the opportunity to share our intricate knowledge of the food supply chain, as well as best practices regarding whole chain traceability during this monumental meeting with the FDA with more than 250 food industry leaders.

In retrospect, one thing is clear—we’re in the midst of a pivotal time of change for the world’s food supply chain. In the United States, the food industry remained status quo for decades, but the introduction of FSMA has brought increased scrutiny and accountability; I think it’s made every food company pause and evaluate where they are with regard to food safety, and that’s a good thing. And now, with the launch of the “New Era” campaign, we’re coming together in a collaborative fashion to map out how technology tools, prevention measures, new business models, and an evolving culture of food safety can be merged as a framework for a long term food safety solution. I agree with the FDA; ‘Smarter Food Safety’ is people-led, FSMA-based, and technology-enabled. It will take all of us working together to reach that goal.

If You Think Plague Is a Thing of the Past, Think Again

Rodents are vectors of more than 50 pathogens, including plague.1 While plague may be considered a problem of the past, according to the World Health Organization, between 2010 and 2015, there were 3,248 cases of reported plague worldwide and 584 deaths. While it is clearly not the 1300’s when the plague killed millions, the CDC confirms, “plague occurs in rural and semi-rural areas of the western United States, primarily in semi-arid upland forests and grasslands where many types of rodent species can be involved.” While the fact that plague is still lurking is a bit surprising, it should be no surprise that rodents can spread more than 50 diseases. Not the least of these diseases is Salmonella braenderup, the cause of recall of approximately 206,749,248 eggs in 2018. The good news: In the age of IoT, new technology can enable an immediate response to help prevent infestations from growing out of control.

With rodent populations on the rise due to climate change and the resultant public health issues in major cities across the United States, public health officials and pest managers face unimaginable challenges in staying ahead of rapidly growing and spreading rodent infestations. Earlier this year, Los Angeles had a typhus outbreak that resulted from a rat infestation near an encampment for those experiencing homelessness. The unsanitary conditions created a harborage for rats that spread the flea-borne illness. Cases of typhoid have doubled in the area since 2012. When and where will the next pathogen outbreak from rodent activity hit?

If that’s not frightening enough, it is important to highlight that once an infected, flea-carrying rodent enters a facility, eliminating the rodent does not always necessarily mean eliminating the presence of plague pathogens. The World Health Organization explains that once vectors have been introduced through rodents and their fleas, it is not enough to eliminate rodents. Vector control must take place before rodent control because “killing rodents before vectors will cause the fleas to jump to new hosts.”

Controlling the spread of pathogens via rodents is becoming increasingly important, particularly in sensitive environments like food processing and manufacturing facilities. Effective management begins with early and accurate detection and sustained through continuous monitoring. However, the traditional method of manual rodent inspection by its very nature cannot provide facility and pest managers with either early detection or continuous monitoring.

Thanks to IoT, monitoring systems can now be used in a wide variety of rodent monitoring devices inside and outside a facility. The systems transmit messages in real time over wireless networks and provide pest managers, facility management and public health officials with 24/7 visibility of rodent activity in a monitored location, which will enable more timely responses and help improve the effectiveness of mitigation efforts. Digital IoT technologies are rapidly becoming the modern proactive tool used to help predict and control rodent issues before they occur in an age when traditional, reactive methods are insufficient.

Northfork Buffalo Burgers, recall

Northfork Bison Distributions, Inc. has issue a voluntary recall of its Bison Ground and Bison/Buffalo Burgers following a multistate outbreak of E. coli O121 and E. coli O103 linked to its ground bison. The ground bison was produced between February 22, 2019 and April 30, 2019, and has expiration dates through October 8, 2020.

Thus far, 21 people have become ill, and eight have been hospitalized, with cases reported in Connecticut, Florida, Mississippi, Missouri, New Jersey, New York and Pennsylvania.

The FDA regulates bison meat, as the authority is not assigned to USDA’s FSIS. Several images of the affected products have been posted on the agency’s website.

During the investigation, the FDA and CDC used traceback and epidemiological information to link to affected ground bison to Northfork Bison, which the agency noted was quick to initiate the recall.

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.

Alert

Following an expanded recall issued this week, JBS Tolleson, Inc. has now recalled about 12,093,271 pounds of non-intact raw beef products over concerns that they may be contaminated with Salmonella Newport. The initial recall of nearly 7 million raw beef products occurred just two months ago. The Class I recall announced today involves an additional 5,156,076 pounds of raw beef products that were produced and packed between July 26 and September 7, 2018, according to USDA’s FSIS . The recalled products have the establishment number “EST. 267” inside the USDA mark of inspection.

According to the CDC, there are currently 246 reported Salmonella Newport illnesses across 25 states, with 59 hospitalizations. No deaths have been reported. FSIS and CDC have been working with case patients who have provided receipts or shopper card numbers to conduct traceback investigations. The agencies are urging consumers to check their freezers for any recalled product.

(UPDATE) CDC Alert: Do Not Eat Romaine Lettuce, Throw It Out

By Food Safety Tech Staff
No Comments
Alert

–UPDATE– November 26, 2018 —

FDA has issued a release stating that the E. coli outbreak is likely linked to romaine lettuce grown in California during the fall timeframe. The agency’s traceback investigation is in progress, and it is looking at shipping records and invoices in order to trace the romaine lettuce supply from places in which ill people have been exposed to where the product was grown. Thus far this information has been connected to romaine lettuce harvested in the Central Coast growing regions located in northern and central California. Locations outside of California have not been linked to this particular outbreak, and thus the FDA is not recommending that consumers or retailers avoid romaine lettuce that has been grown outside of these California regions. The agency has not found evidence of any outbreaks linked to romaine that was grown hydroponically or in a greenhouse.

“During this new stage of the investigation, it is vital that consumers and retailers have an easy way to identify romaine lettuce by both harvest date and harvest location. Labeling with this information on each bag of romaine or signage in stores where labels are not an option would easily differentiate for consumers romaine from unaffected growing regions.” – FDA

As a result, FDA stated that romaine lettuce entering the market will be labeled with a harvest location and date to help consumers distinguish unaffected growing regions.

–END UPDATE–

Just when we thought the E.coli O157:H7 outbreak involving romaine lettuce was over: Today CDC issued a Food Safety Alert informing consumers not to eat ANY romaine lettuce. Retailers and restaurants shouldn’t serve any either.

Wait, wasn’t the outbreak declared over in June? What happened?

“Thirty-two people infected with the outbreak strain of Shiga toxin-producing E. coli O157:H7 have been reported from 11 states.

Illnesses started on dates ranging from October 8, 2018 to October 31, 2018.
Thirteen people were hospitalized, including one person who developed hemolytic uremic syndrome, a type of kidney failure. No deaths have been reported.” – CDC

The agency is urging against the consumption of romaine lettuce because they haven’t been able to identify a common grower, supplier, distributor or brand.

Could we be in for another widespread outbreak? Just last week during a panel discussion at the Food Safety Consortium, the FDA and CDC said that when the last outbreak occurred they knew it would get bad really quickly.

The investigation is ongoing.
