Quick Summary

Yersinia enterocolitica is a gram-negative bacterium that can cause yersiniosis, an acute gastrointestinal infection in humans. This bacterium is widespread in domestic animals like pigs and cattle, as well as in birds and aquatic species.12

Yersiniosis symptoms include fever, diarrhea (sometimes bloody), and abdominal pain. It can also lead to a temporary rash and arthritis. The infection is often acquired through contaminated food, water, or unpasteurized milk. Raw or undercooked pork products are a significant source of infection, as Yersinia enterocolitica can grow even at refrigerator temperatures. While most people recover without treatment, those with weakened immune systems or excess iron may require antibiotics if the infection spreads. Proper sanitation is crucial for prevention.2
