A California company is voluntarily recalling one day’s production of diced and slivered onions and a mix of diced onion and celery because these products may be contaminated with Listeria monocytogenes. Gills Onions, LLC of Oxnard, CA issued the recall after it was notified by the U.S. Food and Drug Administration (FDA) that a random sample of diced yellow onions collected at a retail location had tested positive for Listeria. The company is recalling all foods processed the same day as the diced yellow onions on the same line as the contaminated sample. These products, packaged under the brans “Gill’s Onions,” were shipped between July 2 and 4, 2012 to retailers in Canada and in eight U.S. states, including California, Montana, Oklahoma, Oregon, Pennsylvania, Texas, Utah and Washington. The following is a chart detailing the recalled foods.
