Abstract

Many researches have suggested a link between antibiotic administration in food animals and increase in bacterial resistance in human populations. In this cross-sectional study, the screening for antibiotic residues in kidneys was done using Microbial Inhibition six (6) plate method to provide baseline data for the prevalence of antibiotic residues in animals slaughtered in Abattoir and non- Abattoir slaughter house in Negeri Sembilan district areas. Basically, the agar diffusion method uses six media which have been separately cultured with different types of bacteria that are relatively susceptible and resistant towards specific antimicrobial at certain pH level. Forty one (41) kidney samples and another fourteen (14) samples were obtained from and non–abattoir and approved (Senawang, Negeri Sembilan Abattoir) slaughter houses respectively. Fourteen (34%) of the 41 kidney samples from non–abattoir slaughter houses and 1 (7%) of the 14 samples from non–abattoir slaughter houses were positive for antibiotic residues. The result of the study revealed significant association (p
