Yersiniosis is a diarrhoeal illness caused by the bacteria Yersinia enterocolitica. Only a small number of cases are reported in Scotland each year.
The bacteria can be found in a number of animals, but it's most frequently associated with pigs.
Infection is through faecal-oral transmission through consumption of contaminated food or water, as well as by eating raw or undercooked pork.
Information about the symptoms and managing food poisoning is available on the NHS inform website.
