2011 Snohomish County Petting Zoo
At least 6 people who visited the Forest Park Petting Zoo in Everett, Washington, in June 2011 became ill with E. coli O157:H7 infections. The Snohomish County Health Department investigated the E. coli outbreak and determined that there was a "clear association between disease and being in the open animal interaction area of the forest Park Animal Farm." Investigators determined that direct interaction with calves, and indirect exposure to contaminated surfaces were both associated with E. coli infection.
Recommendations made to the Forest Park Petting Zoo following the E. coli outbreak included:
- Remove calves from the open animal interaction area.
