At least 32 people, including 2 who developed hemolytic uremic syndrome, have been linked to an E. coli O157:H7 outbreak that was traced to salads and wraps in October and November of 2013.
According to the Centers for Disease Control and Prevention, 27 E. coli cases in California, 3 in Washington state, 1 in Texas and 1 in Arizona have been traced to salads and wraps sold by Trader Joe's, Walgreens and Whole Foods. The salads and wraps were manufactured by Green Onion Catering.
In an announcement, the CDC stated: "Epidemiologic and traceback investigations conducted by local, state, and federal officials indicate that consumption of two ready-to-eat salads, Field Fresh Chopped Salad with Grilled Chicken and Mexicali Salad with Chili Lime Chicken, produced by Glass Onion Catering and sold at Trader Joe’s grocery store locations, are one likely source of this outbreak of STEC O157:H7 infections."
On November 10, 2013, Glass Onion Catering voluntarily recalled numerous ready-to-eat salads and sandwich wrap products that may be contaminated with STEC O157:H7. Two lawsuits have been filed against Glass Onion Catering's parent company, Artherstone Foods, by Marler Clark.
