The pathogen poses risk of environmental degradation and health to the inhabitants. A total of 2162 fecal samples were collected per rectum from a representative sample of cattle on 27 dairy farms. The samples were investigated for the presence of <jats:italic>E. coli O157:H<\/jats:italic> by initially enriching using a bacteriological media and detection of the pathogen using real\u2010time polymerase chain reaction technique. <jats:italic>Escherichia coli<\/jats:italic> O157:H7 was detected in 74% of the herds in the target population and in 3.7% of samples collected. An additional 54 animals were identified that were infected with O157 non\u2010H7 strains of <jats:italic>E. coli<\/jats:italic> among 15 farms. Several putative risk factors were associated with the detection of the pathogen on the enrolled farms included age, housing calves indoors, group housing for calves, housing calves in the calf barn, presence of dogs on the farm, and housing post\u2010weaned calves in a cow barn or heifer barn versus a greenhouse. In conclusion, <jats:italic>E. coli<\/jats:italic> O157:H7 was present on the dairy farms of Delaware County and may pose a threat to the people that live and work there. The risk associated with the detection of this pathogen could be reduced by adjusting management factors that were identified in this study.<\/jats:p>","DOI":"10.1002\/jeq2.20494","type":"journal-article","created":{"date-parts":[[2023,5,18]],"date-time":"2023-05-18T07:38:51Z","timestamp":1684395531000},"page":"829-836","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["The
