So far, New York State has had four salmonella cases, according to Fox News. It is unclear what grocery stores these onions have been sold at. It is also unclear where the cases have occurred in New York State. Symptoms include diarrhea, fever, stomach cramps, and more. Recovery is expected without treatment, usually. If you suspect you have a salmonella infection, please contact your healthcare provider.
