What is salmonella?

Page last updated 28 February 2019

Salmonella is a bacteria that can cause an illness called salmonellosis, which affects millions of people each year. People with salmonellosis may experience nausea, diarrhoea, vomiting, abdominal cramps between 12 to 24 hours after infection, which can last up to a week. Most people recover without treatment, but some people may have diarrhoea so severe it causes dehydration. The bacteria can sometimes spread to other parts of the body where it can cause serious complications.
