DENVER (KDVR) — Federal officials say Colorado is one of 34 states affected by a multi-state outbreak of salmonella poisoning. The Food and Drug Administration reports there have been a total of 396 people sickened, with 10 of those in Colorado.

The FDA has identified a company based in Bakersfield, California and states, “Although the investigation has determined that red onions are the likely source of this outbreak, Thomson International, Inc. has notified FDA that it will be recalling all varieties of onions that could have come in contact with potentially contaminated red onions, due to the risk of cross-contamination. The onion recall will include red, white, yellow and sweet onions.”

Red, yellow, white and sweet yellow onions are included in the recall among Thomson’s 11 brands, including: Thomson Premium, TLC Thomson International, Tender Loving Care, El Competitor, Hartley’s Best, Onions 52, Majestic, Imperial Fresh, Kroger, Utah Onions and Food Lion.

The FDA is working with the Centers for Disease Control and Prevention, along with state and local partners during this investigation.

The CDC is advising, “consumers, restaurants, and retailers not to eat, serve, or sell any onions from Thomson International, Inc., or food made with these onions.”

According to health officials, symptoms include diarrhea, fever, and stomach cramps after being exposed to the bacteria. If you believe you may be infected, you are urged to call your doctor.
