Case: FDA Policy Effects on Antimicrobial Resistance in Salmonella Dublin Isolates

Assessing FDA policy effects on antimicrobial resistance in Salmonella Dublin isolates

Angelica Collins & Casey Cazer

Department of Population Medicine & Diagnostic Sciences, Cornell University College of Veterinary Medicine

In 2012 the Food and Drug Administration (FDA) prohibited the extra-label use of cephalosporin class antimicrobials in food-producing animals to reduce the risk of cephalosporin-resistant zoonotic bacteria. The objective of this study is to assess the prevalence of antimicrobial resistant (AMR) Salmonella enterica serotype Dublin before and after this policy change. We have analyzed Salmonella Dublin isolate antimicrobial susceptibility data collected by the National Antimicrobial Resistance Monitoring System at the slaughter stage between 1998 and 2017. Internationally accepted breakpoint values were used to determine if the isolates were resistant or susceptible. Chi-square tests were performed to compare the proportion of resistance before (2006-2011) and after (2012-2017) implementation of the policy. Survival analysis was used to assess shifts in MIC distributions; growth inhibition is used as the event and concentration of the antimicrobial that inhibits growth is used as the time.
