Salmonellosis is one of the foodborne illness acquired by consumption of infected raw or undercooked eggs and causes major public health problem. The aim of this study was isolation and identification of Salmonella spp. from the eggshells and the egg contents samples.Methods: In this study, a total 350 eggs were randomly collected from five local stores in Duhok and Zakho city over a period of 6 months in summer of 2016.

The conventional culture method used for detection of Salmonella spp.Results: Out of the 350 eggs, seventeen (4.85%) samples of eggshells contaminated with Salmonella spp. and none of the egg content samples were contaminated with Salmonella genus. Out of 17 positive eggs, three different Salmonella serotypes were identified including; Salmonella enteritidis (10 strains), Salmonella typhimurium (5 strains), Salmonella typhi (2 strains).Conclusions: The results of the present study provide the recent dataset of the prevalence of Salmonella spp. in eggs sold at local stores in the city. All isolates showed resistant to tetracycline, oxacillin and sulphadimethoxazole due to the indiscriminate use of these antibiotics in chicken at sub-therapeutic level or prophylactic doses which promotes selection of antimicrobial resistant strains and also increases the human health risks associated with consumption of contaminated quail eggs. To the best of our knowledge, this is the first study in Zakho- Duhok city, investigating the occurrence of Salmonella spp. in eggshell and content egg sold at local stores.
