Campylobacter is considered one of the most common causes of bacterial gastroenteritis worldwide, and due to its high potential for contamination and transmission through food, especially red meats, it has garnered significant attention. The present study aimed to assess the prevalence of Campylobacter bacteria in beef samples collected from Urmia County. In this research, 30 beef samples were randomly collected from various butcher shops in Urmia County in the year 2023 and subjected to molecular testing. DNA was extracted from the analyzed beef samples, and to identify the genus Campylobacter, the Nested-PCR method based on the 16S rRNA gene was employed. This technique allowed us to accurately identify the presence of Campylobacter bacteria and differentiate between its various species. The results indicated that out of the 30 beef samples tested, 4 samples (equivalent to 13%) were contaminated with Campylobacter bacteria. These findings suggest that beef can play a significant role in the epidemiology and prevalence of Campylobacter in Urmia County. The relatively high prevalence of Campylobacter in beef supports the notion that these animals act as potential reservoirs for the bacteria, and therefore, greater attention must be directed towards sources of contamination and routes of transmission to humans. Since Campylobacter is primarily transmitted through the consumption of undercooked meats and contamination resulting from a lack of hygiene during meat processing, these results underscore the necessity for broader studies focused on identifying and controlling this bacterium. Furthermore, implementing appropriate strategies for controlling and preventing Campylobacter-related diseases in the community can help reduce the incidence of gastroenteritis and improve public health. Ultimately, achieving successful outcomes in this regard requires interdisciplinary collaboration and consideration of the health, environmental, and economic aspects of this issue.
