Antibiotic resistance patterns of Esetterichia coli isolated from farm families consuming home-raised meat.Am J Epidemiol102:319326, 1975.
Antimicrobial resistance patterns of Escherichia coli isolated from 14 Missouri farm families and their animals were examined for relationships with two typesof exposure: consumption of home-raised meat and animal contact. There was no associationbetween frequency of animal contact and similarity of antibiotic resistance patterns between humans and their cattle or their swine. When consumption of home-raised beef and home-raised pork were each analyzed separately, the observed number of bovine-human matches was significantly greater (p < 0.05) than expected if no association existed, and the number of swine-human matches was of borderline significance (p = 0.073). No association was present on farms where they raised cattleor swine but did not consume home-raised meat. Therefore human exposure to animal E. coli via home-raised meat was more plausible than animal contact as an explanation for interspecies crossover of transferable drug resistance on these farms.
