Potential contributors for ARMs include the widespread use of antimicrobials in humans and animals, as well as the presence of antimicrobials in the environment. It has been suggested (with limited data) that farming practices play a critical role in the rise of ARMs at the preharvest level. Through this research we seek to investigate this hypothesis to dissect the source the antimicrobial resistance contamination in our beef cattle herds. There are compounds and conditions produced in the environment can be selective pressures on neighboring organisms depending on environmental factors such as geography, vegetative cover, soil type, organic-matter content, temperature, available nutrients, and the presence of toxic materials. We will seek to investigate the effects of these conditions on the prevalence of antimicrobial resistance in pre-harvest beef cattle.
