A growing salmonella outbreak dates back to onions from the Mexican state of Chihuahua imported by a trader in Idaho.
According to the Centers for Disease Control, more than 650 people in 37 states have contracted salmonella from rotten onions. The CDC first learned of the outbreak in mid-September, but did not identify the source until about a month later.
ProSource Inc. based in Hailey, Idaho, sold the red, yellow and white onions to restaurants and supermarkets across the country. The CDC advises consumers to dispose of any onions they have on hand, unless they know for sure that the onions are not from ProSource.
The last batch of spoiled onions was imported on August 27, according to the CDC. However, it can take months for onions to work their way through a refrigerated supply chain. 4,444 onions were the source of a similar salmonella outbreak in 2020 that reached 869 cases in 47 states.
