Ongoing Outbreaks: What We Can Learn from the Most Recent Carrot and Cucumber Outbreaks

Last month in our blog, we highlighted the recent E. Coli outbreak stemming from onions served at McDonald’s restaurants. In our blog, we highlighted some key considerations when serving fresh produce that often lacks the kill step that we have with most proteins. However, since that blog was published, we’ve had two more high profile outbreaks across the United States involving fresh produce.

In November, a recall was initiated by a company when their carrots, which were packed as both a standalone product (whole organic carrots) and in organic and conventional vegetable medley packages after it was suspected that they may have been contaminated with E. coli O121:H19. As of late November 2024, investigations by the FDA and CDC have linked contaminated carrots to over 39 illnesses, 15 hospitalizations, and one death.

Cases span the US, including states from Washington, Oregon, and California to states as far east as New York and Massachusetts. The carrots in question were distributed by a national brand and primarily sold at large retail chains. The FDA has issued a recall of the implicated products, urging consumers to check their purchases and discard affected items. The source of contamination appears to be linked to agricultural water used during irrigation.

Almost simultaneously, a Salmonella Typhimurium outbreak has been tied to fresh cucumbers distributed to 36 states. As of this writing in early-December 2024, the outbreak has resulted in 68 reported illnesses across 19 states, with 18 hospitalizations. While no fatalities have been recorded, the widespread nature of the contamination has prompted significant recalls, affecting not only whole cucumbers but also prepackaged salads and sushi products containing the cucumbers.

Retailers and distributors are cooperating with the FDA to remove affected products from store shelves. But for consumers and foodservice operators, it is recommended to avoid eating or serving cucumbers unless you can confirm their origin and safety.


…both of these outbreaks underscore the risk of cross-contamination during food handling and processing.


There isn’t much more that I can add to last month’s blog post related to handling fresh produce, but both of these outbreaks underscore the risk of cross-contamination during food handling and processing. While cucumbers are often considered low risk in terms of contamination, improper handling during washing and packaging can easily spread harmful bacteria. Many times our employees don’t always consider these as “potentially hazardous,” but we must ensure that we follow the same strict sanitation protocols that we require with meat products to prevent cross-contact between contaminated and uncontaminated products​.

These incidents underscore the importance of maintaining rigorous safety standards at every step of the food supply chain. From farming to processing and distribution, gaps in safety practices can lead to significant public health risks. Foodservice managers play a role in this system by staying informed about recalls and acting upon those recalls quickly.

As federal agencies continue to investigate these outbreaks, ongoing collaboration between regulators, producers, and foodservice operators is essential to preventing future incidents and ensure a safer food supply. Risk Nothing. 

 

Protecting Fresh Produce Post-Harvest, Integral to Safe Food

During the height of the summer, at least in the Midwest, farmers markets are in full swing and fresh produce is plentiful. Every backyard gardener is reaping the benefits of their work, with bountiful harvests of tomatoes and cucumbers. Everyone seems to have a neighbor who is trying to pawn off his or her over-production of cucumbers or summer squash during this time of year.  When picking up that produce at the farmer’s market or from your neighbor down the street, have you ever given any thought to the microbial safety of it?  Honestly, even in my position, it certainly is NOT the first thing that comes to my mind.  But, earlier this month, I came across a news story out of Wisconsin discussing a Salmonella outbreak associated with shelled peas sold at a local farmers market. Who would have thought shelled peas would be impacted?  The story noted, and it served as a great reminder, that most outbreaks associated with Salmonella in produce are due to mistakes made in handling or transportation of produce after harvesting.

Properly Cleaning and Sanitizing: The Right Chemical Mix to Maintain Ultimate Effectiveness

A few weeks ago, my family and I had the pleasure of setting sail on a cruise vacation. It is truly one of the only ways that I find that I am able to unplug from work and relax for a small spell. However, as I walked around the ship in our post-COVID world, I couldn’t help but admire all the extra cleaning steps the staff were undertaking to keep us all as safe as possible while in the middle of the ocean with 3,000 other vacationers. All of this cleaning and sanitizing had me thinking about how we each clean and sanitize our own operations and which chemicals we chose to use.

Proper Cooking Temperature: A Basic Food Safety Measure

Each summer, we see an increase in the incidence of foodborne illnesses. Perhaps this is because of the warmer temperatures making temperature control for Time/Temperature Control for Safety (TCS) food more difficult or perhaps it is the increased amount of people who are barbequing this time of year – it is National Picnic Month, after all!

Changing Climate: The Unseen Impact on Food Safety

In June, I was asked to participate in the Allinfoodz podcast, put on by a colleague, Dr. Amit Sharma, at Penn State University.  One of the points Dr. Sharma wanted to discuss was the impact of climate change on food safety, which is something I was certainly aware of, but not something I had done much research on.  However, when preparing for the interview and podcast, it was interesting to learn more about the relationship between the two.
