“Yersiniosis refers to the illnesses caused by Y. enterocolitica and less often by Y. pseudotuberculosis infections. Infection occurs most often in young children. Common symptoms in children are fever, abdominal pain, and diarrhea, which is often bloody.

Most people become infected by eating contaminated food, especially raw or undercooked pork, or through contact with a person who has prepared a pork product, such as chitlins. For example, babies and infants can be infected if their caretakers handle contaminated food and then do not wash their hands properly before handling the child or the child’s toys, bottles, or pacifiers.  People occasionally become infected after drinking contaminated milk or untreated water, or after contact with infected animals or their feces.  On rare occasions, people become infected through person-to-person contact. For example, caretakers can become infected if they do not wash their hands properly after changing the diaper of a child with yersiniosis.”
