Thesis Abstract

Ten (10) samples of suya meat in Enugu were collected randomly and analyzed microbiologically and the isolates were identified as Staphylococcus aureus (35%)Escherichia coli (15%) Streptococcus species (15%) Pseudomanas (35%) . The most frequently isolated organism was Staphylococcus and Pseudomonas. The total viable bacterial counts ranged from 1.9x 3.8x cfu/g whereas, total coliform count ranged 1.1x-3.0x cfu/g on MacConkey and Nutrient agar respectively. The result revealed that the hygienic condition of the meat have fallen below acceptable standard for human comsumption.
