Abstract Distribution of pathogens in retail pork and beef from Beijing supermarkets and markets were investigated by
selective culture and 16S rRNA sequencing. The antibiotic resistant phenotypes of all the isolates were detected, including
7 common antibiotics. Meanwhile, two common erythromycin resistance genes and seven common tetracycline genes were
detected among all the isolates. The results showed that the drug resistance of bacteria isolated from meat samples collected
from markets was more serious; both the isolates from pork and beef showed serious drug resistance; among all the isolated
bacteria, Escherichia/Shigella and Aeromonas genus, which contained some opportunistic pathogen species, showed the
most serious drug resistance. Meanwhile, we also found that the majority of the isolates were non-susceptible (resistant and
intermediate) to several kinds of antibiotic, and some of the isolates carried more than one antibiotic resistance genes (ARGs).
The above evidence showed that drug resistance was common and serious among bacteria isolated from commercial meats.
Both regulators and consumers should pay more attention to it.
