Abstract

The contamination of foodstuffs with different bacteria such as Listeria spp. is important from the viewpoint of public health. Therefore, this study was conducted to check the presence and occurrence of Listeria species in Cattle meats from abattoirs and butcher shops located in Chaharmahal and Bakhtiary province. Two hundred and fifty-five of meat samples were collected. The total Prevalence of Listeria spp. was equal to 12. 94%. The highest (16. 4%) and the lowest (8%) Prevalence of Listeria spp. was found in samples from Farrokhshar abattoir and Shahrekord butcher shops, respectively. Among the six species of Listeria, Listeria innocua was the most prevalent (7. 4%) species; while Listeria seeligeri and Listeria ivanovii were the least prevalent (0. 4%) species. The highest percentage of Prevalence (6. 7%) of Listeria monocytogenes was detected in meat samples from the Hafshejan butcher shops. In the current study, none of the samples was contaminated by Listeria welshimeri. Of the ten isolates of Listeria monocytogenes, the most prevalent (40%) Serotypes were 1/2a and 4b. In addition, the Prevalence of serotype 1/2b was 20%. The results indicated that, due to the presence of Listeria contamination, improvement of sanitation principles in abattoirs and butcher shops is a guarantee of public health safety.
