چکیده مقاله:
Background and aim: Listeria monocytogenes is an opportunistic human pathogen that affects food of animal origin and mainly immunocompromised people, the elderly, infants and pregnant women. The purpose of this study was to investigate the prevalence and antibiotic resistance of Listeria monocytogenes isolated from goat and sheep meat sold in Tehran city.
Materials and Methods: ۵۰ samples of goat and sheep meat were randomly isolated from supply centers in Tehran and transferred to the veterinary laboratory of Tehran University in the fall of ۲۰۲۳. Sampling was also done with swap in tools and equipment used in supply centers.
Results: The results showed that out of a total of ۲۵ samples of goat meat and ۲۵ samples of sheep meat, ۴ samples (۱۶%) of sheep meat and ۸ samples (۳۲%) of goat meat were infected with Listeria monocytogenes. There was a statistically significant relationship between the amount of coliform contamination in goat and sheep meat (p<۰.۰۵). The results of antibiotic resistance showed that the highest level of resistance was related to sulfamethoxazole and amoxiclav. Also, the highest and lowest level of contamination was in the refrigerator (۵۰%) and knife (۱۰%).
Conclusion: The high level of contamination and high antibiotic resistance for Listeria monocytogenes isolates indicates the poor health status in the meat product supply centers in Tehran, and it is necessary for the quality centers to make more efforts to establish strict regulations. Also, in case of gastroenteritis caused by Listeria monocytogenes, the use of antibiotics should be limited.
