Listeria Bacteria Suspected from Onions in Packaged Foods

iStockphoto/Thinkstock(NEW YORK) -- Barbeque sauce, chicken salad and bean dip -- all pre-made products with onions on the ingredient list -- are now reported to be at risk of containing the bacteria known as listeria following a series of recalls earlier this summer from a California-based onion supplier.

Gill's Onions, located in Oxnard, Calif., announced its latest recall last week, the third of the summer.  Included were diced and slivered red and yellow onions, diced celery/onion mix and whole onions.  So far, no illnesses have been reported.

"Our priority right now is to carry out this recall effectively and efficiently in order to reduce the risk to public health," said Steve Gill, president of Gill's Onions.  "We've identified the problem, and we are taking aggressive actions, in addition to our normal food safety measures."

However, the recalled items include more than just diced onions.  Grocery stores across the nation, including Whole Foods, Trader Joe's, Wegmans, Weis and Publix have all recalled products containing onions from Gill's Farms.

"Take something as simple as an onion and realize that a company distributes these onions quite far and wide," said Michele Simon, a public health lawyer and president of Eat, Drink, Politics, a public health advocacy firm.  "They could be contained in products you don't even think about."

Recalled products range from shrimp salad, beet dressing and pre-made corned beef sandwiches in Whole Foods stores in Florida to wingless buffalo blue cheese dip and veggie pizza at Wegman's Food Market stores in Pennsylvania, according to company press releases.

GH Foods CA, Trader Joe's, Huxtable's Kitchen and Simmering Soup brands, Cool Creations, Ken's Foods Inc. and Garden Fresh are other brands that have recalled products containing the possibly-contaminated onions.

Products containing the onions have been distributed to stores in the following states: Alabama, Arizona, Arkansas, California, Florida, Georgia, Illinois, Iowa, Kansas, Kentucky, Missouri, Mississippi, North Carolina, Nebraska, New Mexico, Nevada, Pennsylvania, Ohio, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Washington and Wisconsin.

A full list of recalled food products can be found here.  All recalled products should be discarded and not consumed, the Food and Drug Administration said.

Listeria is a food borne disease-causing bacteria that, according to the FDA, "may cause serious and sometimes fatal infections in young children, frail or elderly people and others with weakened immune systems."  Listeria can also cause miscarriages and stillbirths in pregnant women.  Otherwise healthy individuals may suffer only short-term symptoms, such as high fever, headaches, nausea and diarrhea.
