Prior to joining GMA in 2004, he worked for the USDA/ARS where he was involved with researching hydrodynamic pressure processing to control pathogens in meat. Richard also served as a senior scientist at the research and development department of a food ingredient company in Wisconsin for more than five years. There he developed microbial starter cultures, antimicrobial agents for meat products and significantly reduced the cost of production through process optimization. He has published numerous articles in scientific journals on the subject of pathogenic bacteria control in food products, especially meat.
Dr. Podolak earned his Ph.D. in food science from Kansas State University.
Regina Hildwine, senior director, science policy, labeling and standards is the GMA liaison between the industry and government agencies on food labeling technical and policy subjects and joined GMA in 1982. Ms. Hildwine answers numerous questions from GMA members about labeling regulations, and many in the food industry consider her a point source of information on food labeling rules. In the international arena, she has participated on the U.S. delegations to three Codex Alimentarius committees and has participated for nearly 20 years on the Codex Committee on Food Labeling.
Ms. Hildwine is a Phi Beta Kappa, cum laude graduate of Trinity University, Washington, DC, and holds an M.A. from the University of Maryland, with further graduate study at Princeton University.
Lloyd Hontz, senior director, science policy, compliance and inspection is responsible for providing guidance on technical, scientific, regulatory and legislative issues affecting the meat and poultry industry. Mr. Hontz’s work has focused on United States Department of Agriculture/Food Safety and Inspection Service (FSIS) policies and procedures. He serves as liaison between GMA’s meat and poultry processing members and FSIS on a wide range of inspection issues. He has for over 20 years functioned as staff secretary for the GMA Meat, Poultry and Egg Products Committee, which recently expanded its scope to deal with FDA regulatory issues and changed its name to the Regulatory Inspection and Compliance Committee. He has served the Association and its members for over 34 years.
A native of North Carolina, Mr. Hontz holds a BS in food science from North Carolina State University and an MSPH in environmental science from the University of North Carolina. He first joined the National Canners Association in 1969; served three years in the US Army in the early 1970’s stationed at Natick Laboratories; obtained his master's degree; and returned to the Association in 1977.
Melinda Hayman, Ph.D., director, microbiology is a food microbiologist specializing in Food Safety. Melinda received her Ph.D. in Food Science from the Pennsylvania State University and a B.S. Hons in Microbiology and Biochemistry from the University of Sydney. Melinda joined GMA in 2012 as Director of Microbiology. In this role she oversees critical food safety research, supports membership through technical and laboratory services and interacts with many segments of the food industry, as well as the academic and food regulatory communities, in order to track and interpret food safety issues and deliver effective solutions.
Prior to joining GMA, Melinda was the Director of Technical Services at Food Safety Net Services, where she managed Laboratory Quality Systems, Training, Method Validation, and Special Projects. In addition, Melinda worked as a Food Microbiologist for the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Sydney, Australia.
Ai Kataoka, associate scientist, microbiology is responsible for conducting scientific research projects in the area of microbiological food safety/stability and laboratory services such as food microbiology testing related to quality control issues and foodborne pathogen screening analysis.
