A salmonella outbreak caused by onions is expanding and has infected 640 people from 43 states. At least 85 of them have been hospitalized, the Centers for Disease Control and Prevention (CDC) said.

“If you don’t know where your onions are from, don’t eat, serve, or sell them or any food prepared with them,” the CDC said Friday.
