High-Risk Groups for Foodborne Illness: Who They Are—and How to Protect Them

Some people can eat leftover pizza from the counter and walk away unscathed (we’re not recommending it)—but for many others, a single bite of improperly handled food can lead to hospitalization or worse. Foodborne illness doesn’t affect everyone equally, and as culinary professionals, food handlers, and caretakers, it’s our responsibility to protect those most at risk.

In this edition of SafeBites© by My Food Service License, we highlight the most vulnerable groups, share preventative strategies, and explore the simple truth: proper food safety saves lives.

🚨 Cautionary Tale: A Family Reunion Gone Wrong

It was a beautiful July afternoon in rural Tennessee. A large family reunion buzzed with laughter, lawn games, and a long buffet table filled with home-cooked favorites. One proud aunt brought her “famous” potato salad—prepared early that morning and left out on the table for hours.

By the next day, more than a dozen family members—including two toddlers and an elderly uncle—fell violently ill. Several ended up in the hospital. The cause? Staphylococcus aureus, a toxin-producing bacteria that thrives in food held within the "danger zone" of 41°F to 135°F. The well-intentioned aunt simply didn’t realize that even in a casual setting, unrefrigerated food becomes a health hazard, especially for the most vulnerable.

This incident was a painful reminder: food safety isn’t just a professional standard—it’s a personal responsibility.
