The Saint Louis County Department of Public Health (DPH) is continuing to actively investigate an outbreak of Escherichia coli O157 (E. coli) affecting students, parents and guests of Rockwood Summit High School. As of 12:30 this afternoon, 69 cases have been identified, with some laboratory-confirmed and others presenting compatible symptoms and epidemiological links to confirmed cases.
Further investigation has revealed that individuals who tested positive for E. coli attended two separate events hosted at or catered through Andre’s Banquets and Catering in association with Rockwood Summit High School. Although current details are suggestive of salad being the source of illness, we have not identified a specific ingredient, nor do we have information on the nature or timing of the contamination (i.e., farm vs. later).
