ABSTRACT
The use of antibiotics in livestock production is of food safety concern due to hazards of their residues and transfer of resistant bacteria along the food chain. There are few reported quantitative assessment of meat-borne antibiotic residues and resistant pathogens in southwestern Nigeria. Antibiotics usage in food animal production, antimicrobial residues screening, prevalence of Escherichia coli O157:H7 and levels of oxytetracycline residue in chicken and beef from Lagos, Ibadan and Akure were investigated. A semi-structured questionnaire was administered to 30 poultry and 20 cattle producers purposively selected from the study areas to obtain data on types and sources of antibiotics used, knowledge of disease recognition and practice of withdrawal periods in food animals. Two hundred and fifty samples each of kidney, liver and muscles of slaughtered cattle from one abattoir and 200 samples each of breast muscle and liver from chicken markets and broiler farms in each study area were collected between January 2006 and December 2009. The samples were screened for antimicrobial residues using rapid microbial inhibition assay. Oxytetracycline residue levels were determined by high performance liquid chromatography. Escherichia coli O157:H7 was isolated and screened by culture and latex agglutination respectively. Antibiotics susceptibility of the isolates was performed using multi-disc diffusion method. Data were analysed using descriptive statistics and ANOVA at p
