    Foodborne Diseases

    • Methods to detect emerging foodborne pathogenic bacteria from contaminated foods
    • Application of molecular biology techniques (nanotechnology) for rapid detection of pathogenic bacteria in food and environment
    • Effective detection and control methods of foodborne pathogenic viruses
    • Transmission potentials of prion diseases from food animals to humans

    Factors Associated with Antibiotic-Resistant Pathogens

    • Factors contributing to the increase in antibiotic-resistant pathogens in food

    Foodborne Pathogens

    • Adherence of foodborne pathogens on food and equipment surfaces
    • Mechanisms of pathogenicity of foodborne pathogens

    Epidemiology Study of Foodborne Diseases

    • Effective methods for epidemiology study of foodborne diseases

    Food Microbiology and Food Microbiologists

    • Food microbiology is an applied science involving microbiological quality control of food
    • Disciplines include microbiological aspects of food spoilage and foodborne diseases, bioprocessing of foods, and microbial ecology, physiology, metabolism, and genetics

    Food Safety

    • Importance of proper handling, cooking, and storage of food to prevent bacteria multiplication
    • Parasites, viruses, toxins, and chemicals can contaminate food and cause illness

    Symptoms of Food Poisoning

    • Vary with the source of contamination
    • Include diarrhea, nausea, abdominal pain, vomiting, dehydration, and low-grade fever
    • High-risk groups include older adults, infants, people with chronic diseases, and pregnant individuals

    Food Fermentation and Probiotics

    • Development of strains with desirable metabolic activities by genetic transfer among strains
    • Development of bacteriophage-resistant lactic acid bacteria
    • Metabolic engineering of strains for overproduction of desirable metabolites
    • Sequencing genomes of important lactic acid bacteria and bacteriophages for better understanding of their characteristics

    Food Spoilage

    • Identification and control of new spoilage bacteria associated with current changes in food processing and preservation methods
    • Spoilage due to bacterial enzymes of frozen and refrigerated foods with extended shelf life
    • Development of molecular methods (nanotechnology) to identify metabolites of spoilage bacteria and predict potential shelf life of foods
