    Study Notes

    Food Microbiology Introduction

    • Food microbiology studies microorganisms (bacteria, viruses, fungi, protozoa) that affect, contaminate, or spoil food
    • It's vital for food safety and quality

    Key Areas in Food Microbiology

    • Foodborne Illness: Understanding causes, prevention, and control of foodborne illnesses
    • Food Preservation: Methods to maintain food safety and quality over time
    • Food Spoilage: Investigating microbial processes causing food degradation

    Factors Affecting Microbial Growth

    • Temperature: Microorganisms thrive within optimal temperature ranges
    • pH: Food acidity or alkalinity impacts microbial growth
    • Moisture: Microorganisms need a certain water activity level for growth
    • Oxygen: Some need oxygen, others don't
    • Nutrients: Microorganisms need nutrients for growth and reproduction

    Importance of Food Microbiology

    • Public Health: Protecting consumers from foodborne diseases
    • Food Safety: Guaranteeing food safety for consumption
    • Food Quality: Maintaining food's sensory qualities and nutritional value
    • Food Industry: Providing scientific knowledge for food processing, packaging, and storage

    Common Foodborne Pathogens

    • Bacteria: Salmonella, E. coli, Listeria monocytogenes, Staphylococcus aureus
    • Viruses: Norovirus, Hepatitis A
    • Parasites: Toxoplasma gondii, Trichinella spiralis

    Food Intoxication

    • Staphylococcus aureus is a common cause of food intoxication

    Food Poisoning Symptoms (Examples)

    • E. coli: Watery diarrhea (sometimes bloody), low fever, loss of appetite, nausea, vomiting, stomach pains, and cramps, fatigue
    • Food poisoning symptoms vary depending on the specific pathogen

    Preventing Hepatitis A

    • Vaccination
    • Wash fruits and vegetables
    • Cook food thoroughly
    • Cool food promptly
    • Clean dishes
    • Wash hands
    • Use clean drinking water
