A salmonella outbreak linked to precut onions has infected 73 people in 22 states in the past three months, although no deaths have been reported, the Centers for Disease Control and Prevention said Tuesday.

The illnesses started on dates ranging from Aug. 2 to Sept. 25, the CDC said. Of the 65 cases that the CDC has information for, 15 people have been hospitalized.

On Monday, Gills Onions of Oxnard, California, voluntarily recalled diced red onion, yellow onion, onion and celery, and mirepoix products sold in Arizona, California, Idaho, Montana, Oregon and Washington as a precaution, according to the Food and Drug Administration. The recalled products had August use-by dates, tracking with the beginning of the outbreak.

The recall was begun after the FDA let Gills Onions know that the products had been linked to a CDC traceback about the ongoing outbreak.

In addition to being sold in stores, the onion products were also sent to restaurants and institutions nationwide, the CDC said.

This spread the infection, specifically with the salmonella Thompson strain, to 16 additional states: Colorado, Texas, Wyoming, North Dakota, Iowa, Wisconsin, Michigan, Illinois, Indiana, Ohio, Kentucky, Tennessee, Georgia, Virginia, New York and Massachusetts.

The FDA urged consumers and others to throw away any frozen recalled onion products they may still have.

“Gills Onions has notified its customers who received the recalled product directly from the company and requested that they remove it from commerce,” the FDA said in its news release.

The CDC urges anyone with severe salmonella symptoms — including a fever over 102 degrees Fahrenheit, diarrhea lasting longer than three days, bloody diarrhea and vomiting to the point of not being able to keep down liquids — to contact a health care provider.
