A total of 50 confirmed cases of E. coli were identified. Forty cases had visited the farm or had contact with goats from the farm and 6 had contact with someone who had visited the farm. Eleven cases were hospitalized. Three cases developed HUS. The outbreak strain of E. coli O157 was isolated in 28 out of 61 environmental samples collected.

The farm did not have hand washing stations or signage to inform visitors of potential disease risks.
