Prevalence of Coliform contamination in meat products: Implications for food safety in Katsina metropolis

Abstract

This study assessed the prevalence of Coliform contamination in meat products (chicken, beef, and sausage) sold in Katsina metropolis, Nigeria. A total of 17 samples were analyzed using standard microbiological methods, including serial dilution, spread plate technique, and biochemical characterization. Results revealed Coliform contamination in 40% of chicken, 24% of beef, and 30% of sausage samples, with total coliform counts ranging from 1.2×10² to 1.2×10⁵ CFU/g. Biochemical tests identified Escherichia coli, Klebsiella pneumoniae, and Enterobacter spp. as the predominant contaminants. The findings underscore poor hygiene practices during handling, processing, and storage, highlighting the need for stringent food safety measures. Recommendations include improved hygiene training, regular microbiological monitoring, and implementation of Hazard Analysis and Critical Control Points (HACCP) systems to mitigate public health risks.
