Because of this bacterium, Americans began to reconsider onion dip after a two-decade romance with salsa. In June, the Food and Drug Administration reported that at least 145 people had become sick from consuming a rare strain of salmonella called Salmonella Saintpaul, which got its name from a researcher in St. Paul, Minn., who isolated it in 1942. Initially the blame fell on raw tomatoes, and millions of Americans stopped buying the fruit (yes, it's a fruit).

They also said the offending peppers probably came from Mexico, not the U.S.
