As of November 19, 2013, a total of 32 persons infected with the outbreak strain of E. coli O157:H7 have been reported from four states.
The number of ill persons identified in each state is as follows: Arizona (1), California (27), Texas (1), and Washington (3).
32% of ill persons have been hospitalized. Two ill persons have developed hemolytic uremic syndrome (HUS), and no deaths have been reported.
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 E. coli O157:H7 infections.
