FSIS began monitoring the outbreak Oct. 29. On Nov. 6, the Food and Drug Administration notified FSIS that California public health authorities reported infected patients had eaten prepackaged salads with grilled chicken. FSIS said the patients were sick with "indistinguishable E. coli O157:H7 PFGE (genetic fingerprint) patterns with illness onset dates ranging from Sept. 29, 2013 to Oct. 26, 2013". Fifteen infected people reported eating ready-to-eat pre-packaged salads before getting sick. A trace-back investigation led to Richmond, Calif.-based Glass Onion Catering as the supplier of the implicated products.

FSIS said it is uncommon to find E. coli O157:H7 in poultry products, however the agency is advising consumers to destroy products subject to the recall.
The affected products are being recalled in conjunction with other foods regulated by the Food and Drug Administration (FDA), according to FSIS. The Atlanta-based Centers for Disease Control and Prevention (CDC), FDA, the California Department of Public Health, the Washington State Department of Health, and the Arizona Department of Health Services and FSIS are all investigating the outbreak.
