Florida’s outbreak of listeria has so far led to at least one death, 22 hospitalizations, and an ice cream recall since January. Humans get sick with listeria infections (or listeriosis) from eating soil-contaminated food, undercooked meat, or dairy products that are raw or unpasteurized. Listeria can cause convulsions, coma, miscarriage, and birth defects. It’s the third leading cause of food poisoning deaths in the U.S.
