The FDA adds the potentially affected red, yellow, and white onions from ProSource Inc. were imported between July 1, 2021 through August 27, 2021. Descriptions of these onion types include, but are not limited to, jumbo, colossal, medium, and sweet onions.

Because onions can last up to three months if stored in a cool, dry place, restaurants, retailers, and consumers who purchased these onions may still have them in storage. Nobody should not eat, sell, or serve them, and they should be thrown out immediately.

The bottom line is you should throw out any whole red, white or yellow onions that don't have a sticker or packaging because you simply can't be sure where they originally came from.
