Microbial Profile Of Suya Meat In Enugu State

Twenty (20) samples of suya meat in Enugu were collected randomly and analyzed microbiologically and the isolates were identified as Staphylococcus aureu (35%), Escherichia coli (15%), Streptococcus species (15%), Pseudomonas (35%). The most frequently isolated organisms were Staphylococcus and Pseudomonas. The total viable bacterial counts ranged from 1.9x  3.8x  cfu/g whereas, total coliform count ranged from 1.1x -3.0x  cfu/g on Nutrient agar and MacConkey agar  respectively. The result revealed that the hygienic condition of the meat was below acceptable standard for human comsumption.
