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).
…one in every six Americans experiences a food related illness…48 million people yearly!
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!
Foodborne Illness Myths & Facts
“It must have been something I ate.” That’s the typical statement when a person develops some relatively minor symptoms from food. Maybe not severe enough to go to the doctor so you choose to tough it out without medical care. Sudden onset of flu-like symptoms such as onset of stomach cramps, diarrhea, vomiting and fever could possibly mean you are the victim of a foodborne illness. The illness is sometimes referred to as “food poisoning”, but it’s often misdiagnosed.
Don’t Compromise: Clean and Sanitize
The subject is cleaning and sanitizing. Chefs, food service directors, managers and staff try to practice safe food-handling at every turn in the kitchen. Don’t let that effort go down the drain by slacking off on the many aspects of sanitation. That includes dish and ware-washing techniques (pots, pans, equipment), and cleaning all the areas that give us that “neat as a pin” appearance in your customers eyes. Customers seldom fail to bring that soiled silverware or glass with lipstick on it to the attention of the manager or wait staff. Improperly cleaning and sanitizing of food contact equipment does allow transmission of pathogenic microorganisms to food and ultimately our customer.
The Route to Safer Fresh Fruits and Vegetables
Although fruits and vegetables are one of the healthiest foods sources in our diet, we continue to have foodborne disease outbreaks of significance from produce, sometimes affecting large groups of people in multiple states because of their wide distribution. The CDC estimates that fresh produce now causes a huge number of foodborne illness outbreaks in the United States. Produce needs our continued food safety efforts at the restaurant level as well as at the stages in agricultural production. Occasionally, fresh fruits and vegetables can become contaminated with harmful bacteria or viruses, such as Salmonella, E. coli 0157:H7, Norovirus, and Hepatitis A. This contamination can occur at any point from the field to our table. If eaten, contaminated fruits and vegetables can cause foodborne illness.
Be Cool, Chill Out, Refrigerate Promptly!
The Cold Chain -- Keeping perishable foods at proper cold holding temperatures (between 28°F and 41°F maximum or 0°F for frozen food) from your food producers / manufacturers to your customers has to be one of our strongest links to safe food and high quality. Sometimes that is referred to in the food industry as “maintaining the COLD CHAIN”. Any slip ups in the cold chain, and we have a weak link. Most all of our state food regulations require 41°F as a cold maximum, but colder is a “best practice” policy to maintain.
