Ph.D. in Food Science, Assistant Professor at University of Georgia, Director of the National Center for Home Food Preservation (NCHFP). Current leading authority on home food preservation safety research and USDA guideline updates.
Mae Hartley, Ph.D. is Assistant Professor and Extension Food Safety Specialist at the University of Georgia College of Family and Consumer Sciences, and Director of the National Center for Home Food Preservation (NCHFP). Her research and extension program focuses on preventing foodborne illness in home-preserved foods, with particular emphasis on understanding consumer practices, validating preservation methods, and translating food science into accessible public guidance. She earned an Early Career Scholar Award from UGA for exceptional research. Her work includes studies on safe seafood broth canning (a low-acid food with unique challenges), kombucha fermentation safety, condiment storage practices, and oil infusion safety — the latter addressing a specific botulism risk when herbs are stored in oil at room temperature. She has been cited by the New York Times, Martha Stewart, and the Washington Post for her expertise on food storage and preservation safety. As NCHFP Director, she oversees the continuation of the USDA Complete Guide to Home Canning and the NCHFP website (nchfp.uga.edu), ensuring that the nation's home food preservation guidelines remain current with emerging research. Her personal motivation stems from a childhood experience with foodborne illness that shaped her passion for food microbiology.
