An onion recall from a Southern California grower and food processing firm has led to a cascade of subsequent recalls spanning multiple products and states.

Gills Onions LLC initially issued a voluntary recall of a single day’s production of onions on July 18 due to possible listeria monocytogenes contamination.

The list of recalled items was expanded July 26 to include diced, slivered and whole-peeled onions and diced onion and celery mix with use-by dates on or before Aug. 3, which were shipped to multiple states including California, Arizona, Colorado, Illinois, Montana, New York, Oklahoma, Oregon, Pennsylvania, Texas, Utah and Washington.

Following the expanded recall, a number of products containing the onions as an ingredient have also been recalled.  The list of recalled products includes:

-Various Whole Foods Market prepared foods in Florida

-Trader Joe’s salsa, balela and barbecue chicken salad in Florida, Georgia, North Carolina, South Carolina, Tennessee and Southern region of Virginia

- Cool Creations, LLC bean dips and salsas in Arkansas, Iowa, Kansas, Missouri and Oklahoma

-Various Wegman’s prepared foods at three Pennsylvania stores

-Various GH Foods CA, LLC, products in California, Arizona, Nevada and Utah

Listeria is an organism that can cause serious or fatal infections in children, the elderly and people with compromised immune systems. Otherwise healthy people may suffer symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea.  No illnesses have yet been linked to the recent recalls.
