MSc, BSc


Sarah Martz is a PhD candidate in the department of Population Medicine. Sarah holds an honours bachelor of science in ­­­­­­­­­­­biology and pharmacology from McMaster University, and a master’s of science in biomedical and molecular science from Queen’s University. Sarah also works at The Ontario Ministry of Agriculture Food and Rural Affairs (OMAFRA) as the Risk Identification and Management Coordinator in the Food Safety Inspection Delivery Branch. Her main role is to lead the development and implementation of food safety risk management programs for foods of plant origin. Prior to joining OMAFRA, she worked at the Public Health Agency of Canada and primarily focused on epidemiological surveillance and prevalence projects from human, animal and food origin across Canada.


Research Interests

Sarah's main research interest is antimicrobial resistance (AMR) in microbial communities. Foods derived from domestic animals (e.g., chicken, beef, pork) can be vehicles for transmission of resistant Salmonella, Campylobacter and other bacteria to humans, but less is known about the role of foods of plant origin (e.g. fruit, vegetables) as sources of AMR. A better understanding of fruits and vegetables and their environment as a potential source of AMR is critical for assessing the risk to public health. Sarah's seeks to characterize the importance of these foods, with a focus on those produced in Ontario and the surrounding environment, for transmission of AMR to humans in Canada.
