Escherichia coli is an important zoonotic bacterium that significantly impacts one health concept. E. coli is normally detected in the gut of warm-blooded animals, but some serotypes can cause diseases in humans and animals. Moreover, it can continue for a long time in different environments, replicate in water, and survive outside different hosts. In this study, 171 samples collected from 10 different types of poultry hatcheries (automatic, semiautomatic, and manual “traditional” types) were examined for the prevalence of E. coli. PCR was applied to verify the E. coli isolates via 16S rRNA gene-specific primers. From the gathered samples, 62 E. coli isolates were recovered (36.3%). The highest prevalence was met with the manual “traditional” hatcheries (57.1%) with no significance difference (P = 0.243) in the 3 types of hatcheries. The incidence of E. coli varied significantly in different tested avian types and breeds. The prevalence was 35.7% in duck hatcheries and 37% in chicken hatcheries, with significant differences between breeds of both species (P = 0.024 and 0.001, respectively). The identification of zoonotic E. coli serotypes in this study is concerning, highlighting the need for collaborative efforts across various sectors, including social, environmental, and governance, to promote the adoption of the one health principle in the chicken business. Periodical surveillance, biosecurity measures at the hatcheries and farm levels, and boosting the immunity of birds were recommended to limit the risk of E. coli spread from avian sources to humans.
