One Health: Policies, Practices and Priorities to Address Antimicrobial Resistance

iAMR Logo
iAMR is a nationwide team committed to the shared responsibility to understand and address antimicrobial resistance.

Antimicrobial resistance (AMR) is a critical human health issue worldwide. Although conversations about AMR causes and solutions often focus on the role of agriculture versus the role of human medicine, the reality is that there are many facets to consider when attempting to understand and address antimicrobial resistance. This session – curated by members of a nationwide team cooperating on a new outreach program titled iAMResponsible – will feature invited experts engaging in conversations about the shared responsibility among food producers and processors, consumers, policy makers and the medical community to understand and address antimicrobial resistance.

Interactive Panel

OneHealth and AMR in Agroecosystems

Dr. Lisa Durso, Research Microbiologist, USDA-ARS Agroecosystem Studies Unit (Lincoln, NE)

Antimicrobial resistance (AMR) is a complex issue with communication about it further confused by inconsistent use of terminology across human, animal and environmental systems. During her presentation, Dr. Durso will share her perspective on One Health terminology and “rich points” where differences in interpretations among groups can hinder effective problem solving. She will also discuss the current state of science and recent national and international policies relative to AMR to provide an overview of where we are now and what the future may hold.

Antimicrobial Resistance of Foodborne Pathogens – Are Food Processing Environment and Related Activities a Risk Factor?

Dr. Jovana Kovacevic, Food Safety Extension and Research, Oregon State University

This talk will explore antimicrobial resistance of foodborne pathogens in the context of food processing activities and environments. Special emphasis will be placed on the use of antimicrobials in the food manufacturing industry, selective pressures linked to emergence and spread of foodborne microorganisms with reduced susceptibilities to antimicrobials, and co-selection and cross-resistance phenomena.

Dr. Jovana Kovacevic is an Assistant Professor and Food Safety Extension Specialist at the Oregon State University’s Food Innovation Center (FIC) in Portland, Oregon. In her current role, Dr. Kovacevic directs the food safety program at the FIC focusing on Listeria research, FSMA-related food safety training, education and outreach activities, and she also co-directs and coordinates the USDA-funded Western Regional Center to Enhance Food Safety. Her research uses molecular methods and whole genome sequencing to trace, better understand and prevent contamination events in the food chain, with particular focus on Listeria monocytogenes, and sanitizer and antimicrobial resistance in the food chain.


Fostering Antimicrobial Stewardship in Veterinary Settings

Dr. Michael Murphy, Veterinary Medical Officer, Center for Veterinary Medicine (CVM), Food and Drug Administration (Rockville, MD)

Dr. Murphy will provide a brief summary of the Center for Veterinary Medicine within the U.S. Food and Drug Administration (FDA) and discuss past and future activities by the FDA to address antimicrobial resistance.

Antimicrobial Use and Resistance in United States Beef Production

Dr. John Schmidt, Research Microbiologist, USDA-ARS Meat Animal Research Center (Clay Center, NE)

Food-animals receive approximately 80% (by mass) of antimicrobials used in the United States (U.S.). Cattle account for about 43% of the medically important antimicrobials used during U.S. food-animal production. This presentation will summarize the findings from numerous studies performed by the U.S. Meat Animal Research Center (USMARC) examining the antimicrobial resistance impact of these uses throughout the farm-to-fork continuum.

John Schmidt

John W. Schmidt PhD is a Research Microbiologist with the Meat Safety and Quality Research Unit at the Untied States Department of Agriculture, Agricultural Research Service, United States Meat Animal Research Center (USMARC) located in Clay Center, Nebraska. Since joining USMARC in 2009 John has lead food safety research projects focused on Salmonella, Shiga-toxigenic E. coli, and antimicrobial resistance.  His current research is focused on determining the impact of agricultural antimicrobial use on the occurrence of antimicrobial resistance throughout the beef and pork production and processing continuums.
