摘要：This study was carried out to assess the microbiological quality of fresh raw meats sold at butcher open shops in Ibadan metropolis, Oyo State, Nigeria. 16 samples of pork, goat, beef and chicken meats were obtained from 4 market locations and analyzed using standard microbiological techniques. The total viable count, total staphylococcal count, total enteric count, and total fungal count ranged from 1.0 x106 to 4.6 x 108, 5.0 x 104 to 1.0 x 107, 1.0 x 103 to 1.96 x 108, and 6.0 x 103 to 5.0 x 105 respectively. The percentage of microbial genera isolated from the meat samples were; Salmonella (7.45%), Shigella (6.21%), Staphylococcus (10.56), Micrococcus (17.39%), Enterococcus (1.24%), Streptococcus (4.35%), Yersinia (0.62%), Proteus (16.15%), Escherichia (7.45%), Paracolons (2.49%), yeast (9.94%), Klebsiella (5.59%), Enterobacter (1.86%), and Lactic acid bacteria (8.70%). 2.49% of the isolates obtained from goat meat showed heamolytic positive while 1.24%, 2.49%, and 0.62% of the isolates obtained from chicken, beef, and pig respectively, were able to lyse blood cells. This study confirmed the presence of probable pathogenic organisms in the raw meats sold in some parts of Ibadan metropolis. It significantly points to the great need to evaluate and monitor the occurrence rate of pathogenic organisms in livestock sold in Nigeria. There is also the need for proper and adequate cooking of food of animal origin prior consumption.
