A total of 301 strains of E. coli were isolated from dressed pork carcasses. Drug sensitivity testing of these strains to seven antibiotics was performed. Among the 301 strains of E. coli tested, 195 strains (64.8%) exhibited drug resistance. Isolation rates of drug-resistant strains at various stages in processing were 74.1% after halving, 53.4% after cleaning, 57.9% befor grading and 65.6% in refrigeration. Strains isolated from visceral fluid samples were 91.7% drug-resistant. No E. coli was isolated from the hot water used for dehairing. The highest resistance found among the antibiotics tested was to CTC (51.5% of strains), SA (35.5%) and SM (29.2%). This same order of resistance was found in all samples. Forty six patterns of resistance were observed, ranging from single-agent to seven-agent resistance. The number of patterns of resistance decreased as the carcasses advanced through processing. For all strains isolated, 29.7% were resistant to one agent, 17.4% to two agents, 18.5% to three agents and 16.9% to four agents. Strains resistant to more than two agents were most commonly isolated from carcasses after halving.
