According to press reports, the St. Louis County Department of Public Health announced Tuesday that it is finalizing its investigation into an E. coli outbreak linked to multiple events catered by Andre’s Banquets and Catering.

According to the health department, there have been a total of 115 cases, including 13 hospitalizations. Two people remain hospitalized, and three people have been diagnosed with Hemolytic Uremic Syndrome, or HUS, a rare but serious disease that can occur as a complication of an E. coli infection.

Genetic testing confirmed 25 cases linked to Andre’s through Whole Genome Sequencing, the health department said in a press release. Additional cases with matching WGS profiles have been reported in several states, including Kansas, Illinois, North Dakota, South Dakota, Ohio and Indiana. 

The health department said the genetic data and food histories suggest “leafy greens” as an exposure factor and have “consistently emerged as a key factor” across all states. 

The events under investigation include two Rockwood High School band events, two funerals, and a veterans event, all catered by Andre’s Banquets and Catering between Nov. 6-9.
