Detection and antimicrobial susceptibility of E. coli O157:H7 in the milk supply chain, milking environments and humans in Woliata Sodo, Ethiopia

This study confirmed the presence of multidrug resistant E. coli O157:H7 in the tested sample. Notably, the highest prevalence was detected in milk samples from collection centers, underscoring post harvest contamination as a critical point of intervention. Identification of the pathogen on milkers' hands, farm floors, and human stool samples highlights potential transmission pathways and suggests a tangible risk of foodborne infections. These findings emphasize the critical need for targeted public health strategies, including comprehensive education on hygienic practices and the implementation of effective contamination control measures, to reduce the risk of infection and protect consumer health.
