    Study Notes

    Preventing Chemical Contamination

    • Store chemicals in clearly labeled containers to prevent mix-ups and accidental exposure.
    • Avoid storing food in containers that previously held chemicals to prevent cross-contamination.
    • Follow manufacturer instructions for chemical usage to ensure safety and effectiveness.
    • Isolate chemical storage from food preparation areas to minimize accidental contamination.
    • Do not mix chemicals randomly; improper mixtures can create dangerous reactions.
    • Dispose of chemicals as per manufacturer's guidance to ensure environmental safety.
    • In case of chemical ingestion, contact poison control, consult safety data sheets, and inform a supervisor.
    • Utilize personal protective equipment (PPE) when handling chemicals to reduce risk of exposure.

    Physical Hazards

    • Solid materials in food that can cause harm are classified as physical hazards.
    • Common examples include glass, metal shards, staples, and toothpicks.

    Food Allergens

    • Food allergies occur when the body reacts to a typically harmless protein as a threat.
    • It is vital for foodservice staff to prevent cross-contact between allergenic and non-allergenic foods.
    • Gluten intolerance, while less life-threatening, must still be managed with care.

    Mold

    • Mold can grow on a wide variety of foods under many conditions.
    • Most molds are non-toxic, but some produce harmful toxins.
    • Mold can be killed at temperatures exceeding 140°F (60°C), but toxins may remain, so discard any moldy food.

    Parasites

    • Parasites are organisms that live off their hosts for nourishment.
    • Trichinella spiralis can result from undercooked game meats; it is eradicated by cooking to 160°F (71°C).
    • Fish can harbor parasites like anisakis and tapeworms, which are killed by cooking to 140°F (60°C) or freezing at -31°F (-35°C) for 15 hours or -4°F (-20°C) for seven days.

    Fish Toxins

    • Certain species of fish contain naturally occurring poisons.
    • Ciguatera toxin is linked to red snapper, grouper, and barracuda; Scombroid poisoning is associated with tuna and mackerel.
    • Always procure fish from trusted suppliers to avoid toxin exposure.

    Chemical Hazards

    • Chemical hazards in kitchens include metals from cookware and fish from polluted waters, agricultural chemicals, and cleaning supplies.

    Biological Hazards

    • Biological hazards are pathogens that can cause foodborne illnesses and often go unnoticed (invisible, odorless, tasteless).
    • Types of biological hazards include bacteria, viruses, fungi, parasites, and fish toxins.

    Bacteria

    • Bacteria are a leading cause of foodborne illnesses, thriving on water, food, and favorable temperatures.
    • Implement time and temperature controls for Safety (TCS) foods to deter bacterial growth.

    Control of Bacterial Growth

    • Bacterial proliferation can be limited by managing food source, pH, temperature, time, atmospheric conditions, and moisture levels.

    Viruses

    • Viruses are microscopic agents that can invade cells but cannot reproduce without a host.
    • Hepatitis A and Norovirus are significant viruses of concern in foodservice.

    Preventing Viral Contamination

    • Promote rigorous personal hygiene, clean vegetables, and avoid shellfish from polluted waters to reduce contamination.

    Fungi

    • Edible mushrooms are beneficial in kitchens, but toxic varieties can lead to food contamination.
    • Yeast and mold are common fungi that can spoil food.

    Yeast

    • Yeast ferments sugar, producing alcohol and carbon dioxide.
    • Contamination indicators include slime, color changes, bubbles, and abnormal odors.
    • Yeast is killed at temperatures above 136°F (58°C).
