Abstract
Microbial contamination of food products is one of the main transmission routes of disease in the world today, which is responsible for about two-thirds of all food-borne disease outbreaks although the hygiene process was improved recently. Improving microbial safety and implementing a good food management system are important elements to reduce microbial contamination and improve food safety and security. To improve microbial safety, I conducted inactivation studies on food pathogens and further explored antibiotic resistant risks. Initial research evaluated the efficacy of commercial antimicrobials distribution by comparing electrostatic sprayer with conventional sanitization process. The antibiotics applied by electrostatic spraying achieved significant additional reductions on the foodborne pathogen and more economically feasible compare to the conventional spraying method. Further exploration was carried out building inactivation model analysis on foodborne pathogens under thermal dynamic conditions. Thermal kinetics of foodborne pathogen on moisture enhanced meat were determined and a potential surrogate of Salmonella was identified. Finally, an investigation of the knowledge and attitude of antibiotic resistant issues among local food processors was conducted and results provided suggestions regarding antibiotic risks for local government agencies policy improvement. These studies combined to identify and improve microbial safety on food products by using technologies and statistical analysis.
