Abstract :

Salmonella is one of the most important and common infectious diseases of humans and animals that is caused by Salmonella bacteria and causes the death of many people from human and animal populations annually. Salmonella-infected poultry meat is the primary cause of infection transmission, so identifying the prevalence of Salmonella infection in poultry flocks is a necessary step in taking appropriate control measures to prevent the transmission of infection to human communities. For random sampling, 100 chicken livers were purchased from supermarkets in Malayer city, then sent to the laboratory to evaluate the level of Salmonella infection.After performing bacterial tests, Salmonella serotype was determined using PCR method.In the present study, it was found that 2% of chicken liver was infected with Salmonella bacteria. It should be noted that 2% of the samples had bacterial contamination. It was also found that the predominant salmonella serotype in chicken livers of Malayert city is Salmonella enteritidis. According to the results of the present study, it can be concluded that food of animal origin is a good source for the growth of Salmonella in the country and it is recommended that to prevent bacterial contamination, strict health measures to prevent Contamination of water and food should be done and other livestock products should be cooked enough.
