A salmonella outbreak has been linked to onions.

The CDC said, fresh whole onions are causing a large Salmonella outbreak in 37 states including Ohio and Pennsylvania.

According to the CDC, more than 600 people have become sick and more than 100 of those have been hospitalized.

They are advising people to throw away any unlabeled onions at home. Do not eat, sell, or serve red, white, or yellow onions imported from Mexico and distributed across the U.S by ProSource Inc.  If you can’t tell if an onion is from ProSource Inc., don’t buy or eat it, said the CDC.

ProSource Inc. indicated to the CDC that their onions were last imported on August 27, but these onions can last up to three months in storage and may still be in homes and businesses.
