As if McDonalds wasn’t already unhealthy, they are no longer server tomatoes on their sandwiches because apparently they’ve been making people sick.

Spokeswoman Danya Proud said Monday the world’s largest hamburger chain has stopped serving sliced tomatoes on all of its sandwiches in the United States as a precaution until the source of the salmonella is known. The Centers for Disease Control and Prevention has said at least 23 people have been hospitalized, and no deaths have been reported.
