Prevalence and risk factors for Listeria monocytogenes contamination in Iranian broiler fl ocks
Seif, Saeed
Background: Microbiological safety and quality of broiler meat are equally important to producers, retailers and consumers. Listeriosis is one of the important emerging bacterial zoonotic infections worldwide. Among the different species of the genus Listeria, Listeria monocytogenes is known to cause listeriosis in humans and animals. Listeria monocytogenes is a causative agent of listeriosis, a severe foodborne disease associated with a high case fatality rate. Several food products have been linked with epidemics and sporadic cases of listeriosis, including meat, dairy, vegetable and fi sh products. To prevent product contamination with L. monocytogenes, it is essential to understand listerial contamination routes in the food processing industry. There are few published data concerning risk factors for L. monocytogenes contamination in poultry fl ocks. Information on the occurrence and distribution of Listeria monocytogenes and its risk factors is very limited both in the veterinary and public health sectors in Iran. The aim of this study was to investigate the prevalence and potential risk factors for Listeria monocytogenes contamination in Iranian broiler flocks.Materials, Methods & Results: In this study, farms were separated in two different zones (foothill area in west with less humidity compared with coastal area in north with high humidity). The prevalence of liste
