McDonald’s fast-food outlets in Canada have temporarily removed tomatoes from their menu options, after news south of the border that salmonella food poisoning first linked to uncooked tomatoes has spread to 16 U.S. states.

McDonald’s said in a letter to consumers that it has not experienced any problems to date but consider the move a “precautionary measure."

Below is a news clip from a New Mexico television station about what local restaurants are doing in the wake of 145 sick people in 16 states, and a national advisory from the Food and Drug Administration not to eat certain types of fresh tomatoes.
