Food Poisoning: Identifying a Foodborne Illness
Foodborne illness is no fun. It is likely that at some point in your life, you ate a food item and later became sick. Whether they knew it or not, it is estimated that every year one in every six Americans experiences a food related illness. While those of us in the biz refer to this sickness as a foodborne illness, a poll by NPR back in 2011 found that the general public calls it food poisoning. Whatever term is used, knowing the scope of the problem is the first step in solving it.
We’ve all heard the estimate that 48 million people in the U.S. experience foodborne illness. It is hard to confirm cases because folks may suffer in silence, self-diagnose themselves with the flu, don’t know where to report the illness, or fail to seek medical treatment. Even if they do seek medical care, not all healthcare providers recognize the need to order a stool sample (which is needed for confirmation of pathogen with the suspected food).
The investigation process begins with reporting to local health authorities by individuals, foodservices, or other food companies. Local agencies collaborate with state and federal authorities to gather information and trace back the point of contamination. For instance, if multiple people call in to a foodservice complaining of similar symptoms, there is a good chance that the operation is involved in transmission of the contaminated food. The food may have arrived at the facility already contaminated, or something happened in-house such as temperature abuse, improper preparation procedures, or handling by an infected worker. A confirmed case will show similar pathogen markers in both the food and the stool sample of those infected. The investigation process can be a challenge, but new technology is aiding in these investigations. Brenda Halbrook, is our speaker for the October 21st SafeBites Webinar about investigation of foodborne illness, and she will talk us through the process.
Another challenge in addition to non-reporting of illnesses is that often, the suspected food has been consumed so there is none left to test. School nutrition programs and healthcare foodservice operations retain sample trays for seven days or longer in order to have food available for testing, if needed. This is a good strategy because it can protect the organization from false claims. Further, not all pathogens that cause illness are the same. Different symptoms may be presented and incubation periods (the time from eating the suspect food and when symptoms appear) vary, with some as short as 30 minutes and others up to a week. Cathy’s experience with food poisoning happened 28 years ago after eating lukewarm rice at a restaurant – within 30 minutes symptoms appeared! Her latent self-diagnosis was bacillus cereus. Back then, she suffered in silence. Today, she would contact the restaurant, as well as the local health inspector. Foodservice operators should be prepared for when they receive a call from an unhappy guest. In our second blog for October, we will provide some recommendations to assist foodservices in being prepared to address complaints. Risk nothing!
Was that last 24 Hour “Bug” You Had Really a Foodborne Illness in Disguise?
Within this blog, I have discussed many foodborne pathogens: E. coli, Hepatitis, Salmonella, Listeria monocytogenes, and Campylobacter. But we’ve somehow managed to omit Staphylococcus aureus (S. aureus).
30 Years Later: The Foodborne Illness Outbreak that Changed Food Safety
In January, we hit a major anniversary. One I am betting snuck by many of you – including me! January marked 30 years since the deadly 1993 E. coli O157:H7 outbreak at Jack in the Box restaurants on the west coast. The anniversary wasn’t on any of the major news networks that I recall. It did make it into a few newspapers, at least one or two of the newspapers that are left. It wasn’t until late-February that I realized it.
Does Temperature Really Matter when Washing your Hands?
In January, I reviewed the changes to the 2022 Food Code in my blog (check out Part I and Part II), and one change to the food code that I had mentioned, but didn’t discuss in-depth, was the change that lowered the water temperature a hand sink was required to produce to 85°F, as noted in Section 2-202.12 of the code. This requirement has been in place since the publishing of the 2001 Food Code, which required a water temperature of 100°F. Prior to this, 110°F was required (see the 1999 Food Code). So why the change and does water temperature when washing your hands really matter?
Hand sinks: Often Taken for Granted, but an Essential Part to Effective Hand Hygiene
Late in January, I received a question about hand sinks in a foodservice operation. The question pertained to school staff (teachers and aides) who were using a hand washing sink in the school kitchen. The question came as a matter of who was allowed access to the kitchen to use the sink, but the question itself caused me to go down a rabbit hole of requirements for hand washing sinks in foodservice operations.
