    Study Notes

    Food Hygiene Principles (WHO)

    • Prevent contamination: Contamination of food by pathogens from people, pets, and pests must be avoided.
    • Handwashing: Wash hands before handling food and frequently during preparation, and after using the toilet.
    • Surface Sanitation: Wash and sanitize all food preparation surfaces and equipment, particularly cutting boards.
    • Pest Control: Protect kitchen areas and food from insects and animals.
    • Separate Raw and Cooked: Separate raw and cooked foods to prevent cross-contamination. Use separate utensils and cutting boards for raw foods. Store raw foods below cooked items to avoid contact.
    • Cook Thoroughly: Cook food to appropriate temperatures to kill pathogens. Use a thermometer to ensure proper internal temperatures.
    • Refrigeration: Refrigerate cooked and perishable foods promptly to slow or stop microbial growth.
    • Avoid Room Temperature: Do not leave cooked foods at room temperature for more than 2 hours.
    • Hot Storage: Keep hot foods at a temperature above 60°C before serving.
    • Water and Raw Materials: Use safe water and select fresh, wholesome raw materials.

    Internal Meat Temperatures

    • Beef, Veal, Lamb (whole/pieces):
      • Medium-rare: 63°C
      • Medium: 71°C
      • Well-done: 77°C
    • Pork: 71°C
    • Poultry (chicken, turkey, duck):
      • Whole birds: 74°C
      • Pieces: 82°C
    • Eggs: 74°C
    • Fish: 70°C
    • Shellfish: 74°C
    • Hot dogs/Leftovers: 74°C
    • Ground Meat: 74°C
    • Wild Turkey, Duck, Partridge:
      • Whole: 82°C
      • Breast: 74°C
      • Thighs/Wings: 74°C
      • Stuffing: 74°C

    Six Essential Nutrients

    • Carbohydrates: (e.g., grains, legumes, fruits, vegetables) Main function: provide quick and long-term energy.
    • Proteins: (e.g., meat, fish, eggs, cheese, beans, dairy) Main function: building blocks for growth and repair.
    • Fats: (e.g., butter, oil, cheese, meat, some dairy): Main function: energy storage, cell membranes, hormone formation, vitamin absorption.
    • Vitamins: Essential micronutrients for bodily functions (digestion, repair, defence). Types include fat-soluble (A, D, E, K) and water-soluble (C, B-complex).
    • Fiber: Part of plant foods not digestible. Types include soluble (lowers cholesterol) and insoluble (adds bulk to stool) and aids digestion.
    • Water: Crucial for bodily functions, nutrient transport throughout organs and cells.

    Food Allergies vs. Food Intolerances

    • Food Allergy: Immune system response to food. Triggers allergic reaction (mild: hives, itching; severe: anaphylaxis). Common allergens: peanuts, tree nuts, shellfish.
    • Food Intolerance: Digestive system inability to break down food. Usually less severe than allergies. Common example: lactose intolerance. Can be tolerated in small amounts.

    Foodborne Illnesses

    • Listeriosis: Bacteria in contaminated food or water. Symptoms: fever, nausea, cramps, diarrhea, vomiting, headache. Prevention: cook thoroughly, reheat leftovers well, wash food.
    • Salmonella: Bacteria in contaminated food (e.g., raw poultry, eggs). Symptoms: chills, fever, nausea, diarrhea, vomiting. Prevention: thoroughly cook food, wash hands.
    • Botulism: Toxin in contaminated food (e.g., improperly canned foods). Symptoms: fatigue, weakness, difficulty breathing. Prevention: avoid dented/leaky cans, pressure-can low-acid foods.
    • Clostridium perfringens: Bacteria in contaminated food. Symptoms: abdominal pain, diarrhea, nausea. Prevention: keep food out of danger zone, proper hygiene.
    • E. coli: Bacteria in contaminated food (e.g., raw meat). Symptoms: severe stomach cramps, diarrhea, vomiting. Prevention: fully cook food, wash fresh produce.

    Factors Affecting Food Choices

    Include economical, cultural, familial, social, geographic, and consumer factors. Consider Fair trade, organic supply/demand, packaging and lifespan stages.

    Factors Affecting Food Inequality

    Factors that result in unequal access to food, including ethnicity, gender, culture, age.

    Food Digestion

    • Digestion starts in the mouth with amylase, breaking down carbohydrates.
    • Food travels down the esophagus, then the stomach, where it mixes with digestive juices creating chyme.
    • Chyme passes into the small intestine.
    • Villi in the small intestine absorb nutrients into the bloodstream.
    • The liver, gallbladder, and pancreas aid digestion by producing enzymes and bile.
