Microbiological Analysis of Meat and Their Control

Abstract

The current study was performed in order to check the microbial load of beef and chicken collected from the retail shops of an open area and market where that is available in preserved form. Objective: To compare the microbial load between the meat of an open market area and commercially preserved meat (chicken and beef). The antibiotic resistance profile of isolated pathogens was also checked. Methods: Ten samples of each meat specie (beef and chicken) were analyzed for the presence of different pathogens like Salmonella, Shigella, and pathogenic Escherichia coli mainly. The microbial load was approximately the same in beef as well as chicken. The obtained isolates were then subjected to antimicrobial resistance testing by disc diffusion method. Resistance to chloramphenicol, ampicillin and trimethoprim was determined most frequently. Results: In contrast, the bacterial isolates from beef samples were rarely tested resistant or simply non-resistant as compared to that off chicken samples. The bacterial isolates from chicken samples were tested highly resistant against chloramphenicol, trimethoprim and ampicillin. Conclusion: The significant importance of our findings is resistant rate against bacterial pathogens in chicken seems to be much higher than in beef samples found in variety of environment (different localities).
