| Abstract: | The study has been carried out on 898 food samples of animal origin: bovin meat, ovin, porcin, rabbit, turkey and chicken in 1998 from auto-control food service of Chahed laboratory. II consisted in studying and identifying salmonella serovars and to determine the nature of the most contaminated meat products. The results of the study are as follows: 3.7% of meat product samples are contaminated by salmonella. On the 480 samples of bovin meat, 4.2% are contaminated by salmonella. 3.8% ovin meat is contaminated by salmonella, 1.7% turkey meat and 3.6% chicken meat. Rabbit meat are not contaminated by salmonella. As far as the products of a bovin origin are concerned the results are as follows: -2.7% of meat is contaminated by salmonella, 5.3% of mechanically separated meat and 7.7% of giblets are also contaminated. Therefore salmonella contaminates 4.3% of red meat and 2.6% of fowl. S. anatum, Corvallis, typhimurium, Braenderup, Zanzibar, Enteritidis, Livingstone are different detected serovars. S. anatum represents 40% of contamination whereas. S. typhimurium represents 12% Of contaminations. |
