  • Food sanitation is more than just cleanliness. It included all practices involved in protecting food from risk of contamination, harmful bacteria, poisons and foreign bodies, preventing any bacteria from multiplying to an extent which would result in an illness of consumers; and destroying any harmful bacteria in the food by thorough cooking or processing. The primary tenet of food-service sanitation is absolute cleanliness. It begins with personal hygiene, the safe handling of foods during preparation, and clean utensils, equipment, appliances, storage facilities, kitchen and dining room. Control of the microbial quality of food must focus on the preparation of food itself, food handlers, facilities and equipment. The quality of food depends on the condition when purchased and the time temperature control during storage, preparation and service. Personal hygiene and cleanliness of the facilities and equipment also contribute to food safety.
  • When diners eat out, they expect safe food, clean surroundings and well groomed workers.When there is a disease outbreak in an establishment. It can be one of the reasons why an establishment is forced to closed
  • Wash hands and surfaces often
  • Food handlers are carriers of disease causing bacteria. Food service personnel can contaminate food.
  • FOOD SANITATION, SAFETY & HYGIENE - CHAPTER 1

    1. 1. CHAPTER 1Food Contaminants
    2. 2. What if.....After eating lunch in a cafeteria, halfof this class cannot come to classanymore because of the most of youare experiencing stomach ache,diarrhea, vomiting and fever.
    3. 3. Dangers of food borne illness• Individual – Food borne illness are the greatest danger to food safety. It could result to illness or diseases to an individual that would affect their overall health, work and personal lives.1.Loss of family income2.Increased insurance3.Medical expenses4.Cost of special dietary needs5.Loss of productivity, leisure and travel opportunities6.Death or funeral expense
    4. 4. Establishment – Food borne illness outbreak can cost anestablishment thousands of pesos, it can even be thereason an establishment is forced to closed. • Loss of customers and sales • Loss of prestige and reputation • Lawsuits • Increase insurance premiums • Lowered employee morale • Employee absenteeism • Increase employee turn over • Embarrassment
    5. 5. Definition of terms• Food – Any substance whether simple, mixed or compounded that is used as food, drink, confectionery or condiments.• Safety – is overall quality of food fit for consumption.• Sanitation – is a health of being clean and conducive to health.• Cleanliness – is the absence of visible soil or dirt and is not necessarily sanitized.• Microbiology - the branch of biology that deals with microorganisms and their effect on other microorganisms.• Microorganisms - organism of microscopic or submicroscopic size. (bacterium , protozoan).
    6. 6. • Food Infection - microbial infection resulting from ingestion of contaminated foods.• Food Intoxication - type of illness caused by toxins. Under favorable condition certain bacteria produce chemical compounds called toxins• Food Spoilage - means the original nutritional value, texture, flavor of the food are damaged, the food become harmful to people and unsuitable to eat.• Food borne Illness – A disease carried or transmitted to people by food.
    7. 7. Types of food contaminants:• Biological Contaminant• Physical Contaminant• Chemical Contaminant
    8. 8. Test your knowledge1. Fish that has been properly cooked will be safe to eat2. Cooking can destroy the toxins.3. Copper utensils can cause illnesses when used to prepare acidic foods4. Cleaning products may be stored with packages with foods5. Most biological toxins found in seafood, plants and mushrooms occur naturally , are not caused by the presence of microorganisms.
    9. 9. Biological contaminant - may cause a food borneillness (bacteria, viruses, fungi, parasites, biologicaltoxins)• Examples:• Sea food toxins• Mushroom toxins• Clostridium Botulinum• Salmonella bacteria
    10. 10. Preventing Biological contaminant• Purchase foods only on reputable supplier• Do not use wild mushrooms• Maintain good personal hygiene• Observe proper hand washing• Clean and sanitize equipment• Maintain clean and sanitize facilities• Control pests ** Cooking does not destroy toxins**
    11. 11. Physical Contaminant – any foreign object that accidentally find its way into food• Hair • Glass fragments• Staple wire • Insects• Dust • Extraneous vegetable• Metal shavings matter• Nails • stones• Earrings• Hair clips• Plastics• metal
    12. 12. Preventing Physical Contaminants• Wear hair restraint• Avoid wearing jewelry when preparing, cooking and holding foods (ring, earrings)• Do not carry pencil or pen• Do not wear nail polish or artificial nails when working with foods• Clean can openers regularly• Remove staple wire in the receiving area• Place shields on lights•
    13. 13. Chemical Contaminant – a chemical substance that cancause food borne illness. Substances normally found inrestaurant• Toxic metals• Pesticides• Cleaning product• Sanitizers• Preservatives
    14. 14. Preventing Chemical Contaminants:• Teach employees how to use chemicals• Store chemicals in original containers to prevent accidental misuse, as well as leakage into food• Make sure labels are clearly identify chemical contents of chemical containers• Always chemical according to chemical recommendation• Always test sanitizing solution• Wash hands thoroughly after working with chemicals• Wash foods in cold running water• Monitor pest control operator and make sure chemicals do not contaminate foods
    15. 15. Utensils and equipment containing potentiallytoxic metals:• Lead• Copper• Brass• Zinc• Antimony• Cadmium Highly acidic foods such as tomatoes or lemons can react with metals•
    16. 16. Activity 1: His name is BAC (bacteria) and he is on the attack. He is the invisible enemy and he can make you sick. But you have the power to Fight BAC!and keep your food safe.

    18. 18. Identify the hazards
    19. 19. (3) Main Causes of Food Borne Illness• Cross- Contamination• Time-Temperature Abuse• Poor Personal Hygiene
    20. 20. Cross contamination
    21. 21. Cross Contamination- occurs when microorganisms are transferred from one surface or food to another. The bacteria can transfer from:1. Hand to food2. Food to food3. Equipment to food
    22. 22. PreventingHand to food: Wash hands properlyCover cuts, sores and woundsKeep fingernails short, unpolished & cleanAvoid wearing jewelry, except for plain ring
    23. 23. How to wash hands?
    24. 24. How to wash hands?• 1) Use the hand washing sink with running at approximately 100°F and liquid soap.• 2) Lather hands and exposed arms• 3) Rub hands for at least 20 seconds• 4) Wash hands thoroughly, paying attention to fingernails• 5) Rinse in clean running water. Turn off the faucet with paper towel in your hands• 6) Dry hands using paper towel or air dryer. Not cloth or apron

When to wash hands?Before:• Beginning food preparation • Using handkerchief or• Putting on disposable gloves tissue• Serving customers • Handling inventory • Handling raw foods • Touching or scratching aAfter:• Arriving at work and after part of the body break • Coughing, sneezing• Using the restroom, washing • Handling garbage sinks• Eating, drinking, smoking, • Touching dirty surfaces chewing tobacco and gums• Using the telephone• Using handkerchief or tissue
    26. 26. Food to Food Contamination• - When harmful organisms from one food contaminate other foods. (raw meats, thawing meat on top of the shelf where it can drip on the other foods)
    27. 27. Preventing food to food contamination• Store cooked foods that will not be cooked in the refrigerator on a higher shelf than raw foods.• Best to practice mix left over foods with fresh foods• Wash fruits & veg, in a cold running water• Do not let raw meat and raw vegetables be prepared on the same surface at the same time
    28. 28. Equipment to Food Contamination• How to prevent:• Use separate cutting boards for different foods (meat- veg)• Prepare raw foods in separate area from fresh and ready to eat foods• Clean & sanitize equipment, work surfaces & utensils after preparing each foods• Use specific containers for various food products.• Make sure cloth and paper towel use for wiping spills are not used for any other purposes
    29. 29. Time Temperature Abuse
    30. 30. • TIME TEMPERATURE ABUSE – happens when the food is exposed to Temperature Danger Zone (41⁰F - 140⁰F) for more than 4 hrs.
    31. 31. Time Temperature Abuse occur when:• Food is not stored, prepared or held at a required temperature• Food is not cooked or reheated to temperature high enough to kill harmful microorganisms• Food is not cooled low enough fast• Food is prepared in advance and not set to a safe required internal temperature while the food is on hold
    32. 32. Preventing Time Temp. Abuse• Never expose the food to Temperature danger zone: 41°F - 140°F• Not to exceed 4 hours, except cool-down• Document temperatures & time• Includes receiving, storage, preparation, holding, serving, cooling, and reheating• Pass food through danger zone quickly
    33. 33. Keep hot foods hot. Keep cold foods cold Don’t keep the food at allInternal temperature should be 140°F to prevent harmful microbes from growing
    34. 34. Poor Personal Hygiene
    35. 35. Stay home if someone is sufferingfrom these illnesses:• Hepatitis A• Shigella• E-Coli Infection• Salmonella• * Sick employees must not work with foods*
    36. 36. Keeping Good Personal Hygiene• Medicines should be kept inside the locker and away from foods• Clean and cover cuts and wounds• Never use bare hands when handling ready to eat foods• Disposable gloves should be used once• Take a bath everyday• Wear appropriate attire• Refrain from wearing jewelry, make ups, and nail polish• Observe proper hand washing procedures at all times
    37. 37. POTENTIALLY HAZARDOUS FOODS• Food most likely to become unsafe typically has the following characteristics:• Water activity level of .85• Ph level 4.6 to 7.5• High protein content
    38. 38. • Fish • Sea foods• Meat (beef, pork, lamb) • Sprouts & raw seeds• Milk & milk products • Sliced melons• Cooked rice, beans • Eggs• Textured Soy Protein • Baked/boiled potatoes• And meat alternatives • Garlic in Oil Mixture• 6. Poultry
