Ground beef pathogen dynamics and the current scope of the impact of foreign materials on meat and pet food products


This thesis provides an overview of ground beef consumption and the state of microbial testing of ground beef. The study focuses on understanding dynamic growth relationships between pathogenic and non-pathogenic bacteria in ground beef and how this information might be used to predict the presence of pathogens or the onset of microbial spoilage. Additionally, this thesis examines current United States Department of Agriculture Food Safety Inspection Service (USDA-FSIS) and the Food and Drug Administration (FDA) regulations around foreign material adulterated meat and pet food. The review looks at the challenges between the two regulatory bodies and provides guidance for improvement.
