Thesis Abstract

The present study was carried out to determine the bacteriological quality of pasteurized liquid milk samples sold at different shops in students market located at Imo state University front gate. A total of four samples were collected. The samples were examined to determine the total heterophilic bacterial count and total coliform count. Results revealed that two of the samples (1 and 2) yielded no growth on both Nutrient agar and MacConkey agar hence, were tagged satisfactory. Sample 2 and 3 yielded growth that ranges from 7.0X104 – 9.0 X104, 1.3 X105 – 1.3 X105 respectively. Further identification test carried out showed the presence of Escherichia coli and Enterobacter spp. in sample 3 and 4 hence they were tagged unsatisfactory. The presence of coliform bacteria shows the possibility of pathogenic bacteria and could cause disease.
