Yersinia enterocolitica is a bacterium which causes ~87,000 human cases of foodborne illness (yersiniosis) and 1,100 hospitalizations annually in the United States. Consumption of contaminated dairy products (milk and ice cream), water and vegetables (tofu) have caused human illness. Eating contaminated raw/undercooked pork is a major risk factor for infection. Yersiniosis results in diarrhea, fever and abdominal pains, mimicking appendicitis.
