Occurrence: mainly in pigs but humans can also be carriers.
Incubation: 3-7 days.
Symptoms: abdominal pain, cramping, bloody diarrhea, vomiting and fever. Reiter's syndrome and reactive arthritis have occurred as a secondary disease.
Reason for outbreaks: the most probable cause of outbreaks is food that is not heated correctly or raw, but contamination has occurred even after heating. The bacteria can survive in refrigerator temperatures and long expiration dates make this problem worse.
Prevention: heat the food properly, good hygiene, adequate fridge storage as well as fresh food.
