The Food and Drug Administration is warning consumers not to eat Evergreen Produce brand alfalfa sprouts or spicy sprouts because they may be linked to 20 cases of salmonella poisoning.

The Idaho-based company has not recalled the sprouts though they are possibly linked to illnesses in Idaho, Montana, New Jersey, North Dakota and Washington state.

The FDA warned consumers not to eat sprouts labeled “Evergreen Produce” or “Evergreen Produce Inc.” The sprouts were distributed in Idaho, Montana and Washington state.
