Treatment

Infections by Yersinia enterocolitica are usually self-limiting and will resolve on their own in most patients who recover without any antibiotic treatment within a seven days to three weeks. Hydration is important in uncomplicated cases of diarrhea caused by the organism and will be sufficient treatment in the infection, however in severe or more complicated cases of infection antibiotic treatment may be necessary. The antibiotics commonly used are aminoglycosides, doxycycline, trimethoprim-sulfamethoxazole, or fluoroquinolones.

Prevention

Prevention of Yersinia enterocolitica infection is easy if one is aware of what to avoid. The most common mode of transmission is via poultry and livestock. Thus, avoid raw or undercooked meats. Make sure that milk products are pasteurized before consumption. If raw meat must be handled, clean hands thoroughly to avoid cross-contamination. Beware of cross-contamination in the kitchen by cleaning all surfaces and appliances with soap and hot water. Animal feces may also be contaminated so dispose of all animal waste properly.
