Pathogenic Microbial Contaminants from Roasted Pork Sold in Uyo Metropolis, Nigeria and Public Health Implications

Abstract

- Isolation of pathogenic microbial contaminants from roasted pork sold in Uyo metropolis, Nigeria was conducted using standard microbiological techniques. Pathogenic microorganisms isolated were Escherichia coli, Staphylococcus aureus, Salmonella spp, Enterobacter spp, Vibrio spp, Penicillium spp and Aspergillus spp. Total heterotrophic counts (THBC) for freshly prepared and exposed roasted pork (FPERP) samples ranged from 2.0x104 CFU/g #x2013; 4.2x104CFU/g while for dried and exposed roasted pork (DERP) samples ranged from 5.3x104(CFU/g) to too numerous to count (TNTC). The total enterobacteriaceae count (TEC) and total coliform counts (TCC) values were higher in DERP. Total Vibrio count (TVC) and total mycological count (TMC) were recorded only in DERP. The high microbial counts and diversity of these contaminants from these pork samples is an indication of its low microbiological quality. Thus, proper hygienic condition is recommended before and after preparation of the pork to prevent it from being a potential source of infections to the public.
