Abstract:

The levels of some heavy metals and pathogenic bacteria were analyzed in 60 samples of raw chicken meat sold in three major markets (Effurun, Ekpan and Ugborikoko) within Delta State using standard techniques. The heavy metals concentrations were 49.11 %, 27.5 % and 23.4 % for each market respectively, and in the order Zn > Pb > Mn> Ni > Cu > Cd. Only lead was above permissible limits of FAO/WHO. Effurun samples had the highest counts for Staphylococcus aureus (4.92 log10 CFU/g), while Escherichia coli counts (4.01 log10 CFU/g) were highest in Ugborikoko and Salmonella counts (1.87 log10 CFU/g) were highest in Ekpan samples. The antibiotic resistance was 41.1 % in E. coli, 33.9 % in S. aureus and 25.0 % in Salmonella sp. The contaminations could be linked to gross unhygienic handling and poor environmental sanitation practices. The presence of Pb above permissible limit and multi-drug antibiotic-resistant isolates calls for a greater public awareness for improved environmental sanitation, proper use of antibiotics in poultry farms, use of clean processing water, strict hygienic handling practices and proper thermal treatment to prevent chemical and microbial hazards.
