Abstract

Swabs from 20 beef and 30 pork carcasses in Shah Alam abattoir indicated presence of various species of organisms. The contamination by h coli was 20% and 25% in pork and in beef respectively. The most common isolated organism from pork carcasses was Staphylococcus aureus (70%) whereas from beef, it was Streptococcus species (70%). Among the 61 strains of E. coli, Klebsiella pneumoniae, Staphylococcus aureus and Streptococcus species isolated, 32 were found to be antibiotic resistant. Among them, 50\ were monoresistant and 50% were resistant to 2 to 3 antibiotics, while only one isolate (a strain of S.aureus) was resistant to 4 antibiotics. None was found to be resistant to all the 6 antibiotics. Resistant E. coli from pork was more common compared to beef. E. coli in pork was found to be resistant to ampicillin, kanamycin, streptomycin and tetracycline, while in beef this organism was only resistant to ampicillin. In pork, most of the organism were resistant to tetracycline and streptomycin beef. Resistance pattern of staphylococci was similar in pork and Resistance to erythromycin, methicillin, penicillin and streptomycin was observed both in beef and pork carcasses. However, resistance to tetracycline was seen in pork but not in beef. Streptococcus species showed little resistance in both beef and pork carcasses.
