Yersiniosis

• Diarrhea (often bloody)
• Abdominal pain, which can mimic appendicitis
• Fever
• Nausea and vomiting
• Skin rash (erythema nodosum) or joint pain (reactive arthritis) can occur post-infection

Yersiniosis primarily spreads through the fecal-oral route, often by consuming raw or undercooked pork, contaminated unpasteurized milk, or untreated water. Direct contact with infected animals, especially pigs, or their feces can also lead to transmission, as can person-to-person spread in household settings or childcare centers.

• Thoroughly cook pork and other meats.
• Wash hands with soap and water before eating, after handling raw meat, and after contact with animals.
• Avoid consuming unpasteurized milk and untreated water.
• Prevent cross-contamination of food in the kitchen.
• No vaccine is available for Yersiniosis.
