Yersinia pseudotuberculosis symptoms
Yersinia pseudotuberculosis causes stomach cramps and symptoms that mimic appendicitis, such as tummy pain on the right-hand side. Rashes and joint pain are common. You can also get diarrhoea, but this is rare.
Yersinia pseudotuberculosis has a 3 to 21 day incubation period.
How you can be exposed to Yersinia
Yersinia pseudotuberculosis is usually spread by eating or drinking contaminated food or water, particularly raw produce. Person-to-person spread is uncommon.
How you can avoid infection
Follow good food safety practices, most importantly:
- wash hands with soap and water before eating and preparing food
- wash fresh fruit and vegetables before eating
- don't eat raw or undercooked meat.
