A total of 223 produce samples and environmental swabs collected from various packaging sheds were examined by enumerating total aerobic plate count, total coliform, Escherichia coli and select bacterial pathogens; Bacillus cereus, E. coli, Listeria monocytogenes, Salmonella spp., and Staphylococcus aureus. B. cereus isolates were further screened for carbohydrate utilization, antibiotics susceptibility, and presence of pathogenic gene. Total aerobic plate, total coliform, and E. coli counts of fresh produce ranged from 4.6 to 6.6, 1 to 3.0, and less than 1 to 2 log CFU/g, respectively. The prevalence of pathogens for all samples was 21.5%, and 0.89% for B. cereus and S. aureus, respectively. However, no pathogenic E. coli, L. monocytogenes, and Salmonella spp. were detected. Most of the B. cereus isolates identified were susceptible to penicillin, polymyxin B, ampicillin, oxacillin, and cefotaxime, whereas none of the isolates were positive for emetic toxin, an indication that cleansing procedure at the packaging sheds was not effective. Thorough sanitation and aseptic handling of fresh produce through out the packaging facilities is accentuated.
