  • 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.
  • Transcript

    • 1. CHAPTER 1Food Contaminants
    • 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. 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. 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. 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. • 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. Types of food contaminants:• Biological Contaminant• Physical Contaminant• Chemical Contaminant
    • 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. Biological contaminant - may cause a food borneillness (bacteria, viruses, fungi, parasites, biologicaltoxins)• Examples:• Sea food toxins• Mushroom toxins• Clostridium Botulinum• Salmonella bacteria
    • 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. 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. 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. Chemical Contaminant – a chemical substance that cancause food borne illness. Substances normally found inrestaurant• Toxic metals• Pesticides• Cleaning product• Sanitizers• Preservatives
    • 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. 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. 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. Identify the hazards
    • 19. (3) Main Causes of Food Borne Illness• Cross- Contamination• Time-Temperature Abuse• Poor Personal Hygiene
    • 20. Cross contamination
    • 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. PreventingHand to food: Wash hands properlyCover cuts, sores and woundsKeep fingernails short, unpolished & cleanAvoid wearing jewelry, except for plain ring
    • 23. How to wash hands?
    • 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
