Abstract:
Tetracycline is the most commonly abused and misused antibiotic by layer poultry farmers in Maiduguri Metropolis. Lack of information on the residue of tetracycline prompted the need to ascertain the level of tetracycline residue in commercial eggs meant for human consumption.
Multistage sampling technique was used in selecting layer farms and retail outlets from 4 major districts within the city of Maiduguri Viz; Bolori, Gwange, Kyarimi Park and Shehuri North. Information on the sources of eggs were obtained from the commercial egg retailers. Tetracycline ELISATest Kits from Maxsignal South Africa was used for the analysis according to manufacturer's instruction.
One hundred and eighty-six table egg samples were collected for the study, 68 were sourced from 35 randomly selected layer farms and 118 were from 36 randomly selected retail outlets. Forty-one (60.29%) and Eighteen (15.25%)had detectable tetracycline residue,with overall mean residue concentration of 3.0 ug/kg and 3.18 ug/kg in layer farms and retail outlets respectively. The tetracycline residue is far below the standard of 400 ug/kg maximum residue level set by Codex Alimentarius Commission.
