S2E33 Afternoon Picnic: How Microbes Move Through a Summer Meal

It’s afternoon in our journey From Sunrise to Starlight, and we’re spreading out the picnic blanket. This week, we’re following the hidden microbial pathways running through a summer meal. From farms and kitchens to the cooler, the blanket, and eventually us. We’ll explore how foodborne pathogens such as Salmonella, Listeria, Cyclospora, and norovirus reach our food, what happens as the cooler warms, and how hands, utensils, flies, ants, and even a shared bag of chips can turn a picnic into a transmission network. Plus: Does the five-second rule work? Can ants actually contaminate your food? Is mayonnaise really the problem with potato salad? And when the picnic is over, which leftovers should come home? Pull up a corner of the blanket. Lunch is served. See companion blog post for citations. Subscribe to Field Notes to continue the conversation.
