    Study Notes

    Foodborne Hazards

    • Foodborne hazards are primarily categorized into chemical, physical, and biological hazards.

    Chemical Hazard

    • Consists of toxic substances from natural or added sources during food processing.
    • Common contaminants include pesticides, fertilizers, cleaning compounds, food additives.
    • Can cause severe poisoning and allergic reactions if food is contaminated.

    Physical Hazard

    • Involves foreign objects in food leading to injury or illness.
    • Sources include glass, metal, toothpicks, jewelry, human hair, and dirt.
    • Naturally occurring objects like fish bones also fall under this category.

    Biological Hazard

    • Refers to pathogens that cause illness when consumed.

    Risk

    • Defined as the probability and severity of adverse health effects due to food hazards.
    • Types of risks include business, non-business, and financial risks.

    Causes of Business Risks

    • Natural Causes: Natural disasters impacting operations.
    • Human Causes: Negligence, strikes, mismanagement.
    • Economic Causes: Effects of recession on the business.

    Potential Risks in Hospitality and Tourism

    • Innovation risks associated with technological advancements and cybersecurity threats.
    • Safety risks related to food safety, slips and falls.
    • Reputational risks due to reliance on online customer reviews.
    • Natural disasters, including volatile weather events and disease epidemics.

    Risk Management

    • Involves preemptively identifying, analyzing, and mitigating potential risks.

    Bacteria

    • Ubiquitous presence; undetectable by sight, smell, or taste.
    • Rapid growth occurs under optimal FAT TOM conditions:
      • Food
      • Acidity
      • Temperature
      • Time
      • Oxygen
      • Moisture

    Temperature Control for Safety (TCS) Food

    • Includes dairy, eggs, cut vegetables, fish, shellfish, and cooked grains; conducive to bacterial growth.

    Acidity

    • Ideal growth occurs in low-acid foods; pH scale from 0 (highly acidic) to 14 (highly alkaline), with 7 being neutral.

    Temperature

    • Growth thrives in the Temperature Danger Zone (40°F to 140°F).
    • Some bacteria can multiply at refrigeration temperatures, while freezing (0°F) or cooking (above 145°F) is recommended for safety.

    Time

    • Bacteria need time within the TDZ to grow; significant risk after four hours.

    Oxygen Requirements

    • Certain bacteria thrive on oxygen (aerobic), while others grow without it (anaerobic).
    • Some can survive in both environments.

    Moisture

    • High moisture levels favor bacterial growth; water activity (aw) needed ranges between 0.0 to 1.0.

    Common Foodborne Illness-causing Bacteria

    • Salmonella Typhi: Linked to ready-to-eat foods and beverages; prevent through hygiene and cooking practices.
    • Nontyphoidal Salmonella: Found in poultry, meat, dairy; prevention through cooking and avoiding cross-contamination.
    • Shigella spp.: Contaminated by human feces, affects salads and produce; hygiene and controlling staff illness are key.
    • Shiga toxin-producing E. coli: Linked with raw ground beef and produce; requires strict hygiene and proper cooking.

    Viruses

    • Dependent on hosts for growth; do not multiply in food but can remain infectious.
    • Major viruses include Hepatitis A and Norovirus, both affecting ready-to-eat foods and shellfish.

    Prevention of Viruses

    • Critical measures include excluding infected staff, proper handwashing, and avoiding bare-hand contact with food.

    Parasites

    • Require hosts for survival and reproduction; sourced from seafood and contaminated water.
    • Prevention includes purchasing from reputable suppliers and ensuring proper cooking temperatures.

    Fungi

    • Includes yeasts, molds, and mushrooms; some produce toxins.
    • Moldy food should be discarded unless it’s a natural part of the food; purchase mushrooms from approved suppliers.
