A Sonoma County woman sickened with E. coli infection after eating a salad made by Glass Onion Catering filed a lawsuit against the company on Thursday. The lawsuit was filed in Sonoma County Superior Court by Seattle-based food-safety law firm Marler Clark and San Diego-based Gordon & Holmes, which are representing Nancy Gruchawka. (Marler Clark underwrites Food Safety News.) This is the first lawsuit filed against Glass Onion Catering, the company whose salads and wraps have been identified as the source of an E. coli outbreak among residents of three states. According to the complaint, Gruchawka consumed a salad manufactured by Glass Onion Catering on Oct. 15, 2013. She fell ill with symptoms of E. coli infection on Oct. 18 and was admitted to Santa Rosa Memorial Hospital for treatment on Oct. 30. Her attorneys assert that a stool sample obtained while she was hospitalized tested positive for a strain of E. coli O157:H7 that was an indistinguishable match to the Glass Onion Catering outbreak strain. Although Gruchawka was released from the hospital after one day of treatment, the complaint alleges that she continues to suffer from the symptoms of her E. coli infection. As of Nov. 12, the Centers for Disease Control and Prevention had received reports of 26 E. coli cases traced to Glass Onion products, with 22 of those cases reported among California residents. Glass Onion Catering has recalled its salads and wraps sold at Walgreens, Trader Joe’s and Whole Foods stores.
