E N D
Microorganisms • The major cause of a foodborne illness • Cannot be felt, seen or tasted • Can multiply very quickly in potentially hazardous foods • Most of the foods we eat contains one or more types of microorganisms
Potentially Hazardous Foods A food capable of supporting the rapid and progressive growth of harmful microoganisms
Types of Microorganisms • Bacteria • Virus • Parasite • Fungus • Two groups of food contaminates • Pathogen (cannot see or smell or taste) • Spoilage (can be seen or smelled or tasted)
How do Microorganisms Grow • FAT TOM • Food (potentially hazardous foods) • Acid (pH slightly acidic or neutral) • Temperature (danger zone 41-135) • Time (Less than four hours) • Oxygen (presence of) • Moisture (water helps growth)
Foodborne Illness • Caused by bacteria • Salmonellosis • Shigellosis • Vibrio Gastroenteritis • Hemorrhagic Colitis • Staphylococcal Intoxication • Botulism • Caused by virus • Hepatitis A
Restrictions from Work • If you or a worker is experiencing • Sore throat • Running nose • Diarrhea • Fever • Vomiting BEST PRACTICE IS TO GO HOME
Cross Contamination • A foodservice worker handles the food contact area of a plate or glass • Preparation of cooked food where raw food had been without proper cleaning and sanititation
Types of Hazardous Substances • Physical • Hair, bandages, dirt, metal items, fingernails • Biological • Bacteria, viruses, parasites, toxins • Chemical • Cleaning products, toxic metal residue, pesticides
Ways Food Can Become Contaminated • Poor Personal Hygiene • Leading cause of foodborne illnesses • Improper handwashing • Dirty work clothes • Temperature and Time Abuse • 41 to 135 degrees F is the danger zone • No more than four hours in the danger zone • Cleaning and Sanitizing
Basics of Good Hygiene • Good personal grooming • Wearing clean clothes • Proper use of aprons • Hair restraints • Jewelry should be removed • Fingernails trimmed and clean
Proper Handwashing • Rinse hands in warm water (~105ºF) • Apply hand soap • Scrub hands and exposed arms for 20 seconds (don’t forget between fingers and under rings) • Rinse hands • Use a single serve towel or air dryer • Apply hand sanitizer (optional)
Proper Handwashing • At no time should you wash your hands in a prep sink or dishwashing sink. • Hands should be washed in a designated hand washing station.
When to Wash Hands • After using the bathroom • After touching bare body parts • After coughing, sneezing, using tissues • After eating, drinking, smoking • After handling soiled equipment or utensils • After food preparation • After clearing table or dishes • After removing/disposing of trash
Proper Use of Gloves • Gloves can contaminate as well, do not rely on gloves to feel you are safe. • Gloves need to be changed: • After completing a task and beginning a new task • If they become dirty • After handing raw meat, poultry, or fish • Before handling ready-to-eat or cooked food
Proper Care of Cuts, Burns, Sores or Infections • Report to supervisor • Cover with a clean dry bandage • May need to be reassigned to non-food contact duties • Wash before putting bandage on each time you change the bandage
Four Methods of Thawing Food • In refrigerator at 41ºF or lower, on the bottom shelf and in a container which will hold thawing liquid • Under potable (drinking) running water that is 70ºF or lower • In the microwave if it is to be cooked immediately • In the regular cooking process
Temperature Danger Zone • 41ºF to 135ºF • Must be either cooked or stored below 41ºF within 4 hours
Cold Foods 41ºF or lower Hot Foods 140ºF or higher Correct Temperatures for Holding Food
Proper Minimum Internal Cooking Temperature • Poultry • 165ºF for 15 seconds • Ground Meats • 155ºF for 15 seconds • Pork & Beef (Steak or Chops) • 145ºF for 15 seconds • Fish • 145ºF for 15 seconds • Reheat all food to an internal temperature of 165ºF
Serving Food Properly • Hold plates by the bottom or at the edge • Never touch the food contact surface • Hold cups by bottom or handle • Never put fingers on the rim of the glass, inside the glass • Hold silverware by the handle • Never touch the food contact surface • Use long handled utensils such as tongs, scoops for one food only • Your hands should never come in contact with the food • Scoop ice with proper utensil not a cup
Cooling Foods • Two Stage Method of Cooling • Stage 1 – cool food from 140ºF to 70ºF within two hours • Stage 2 – cool food from 70ºF to 41ºF within four hours • Methods to Cool Food • Ice Bath • Divide food in shallow pans, then refrigerate • Blast Chiller
Accepting or Rejecting Food Delivery • Use the senses (smell, sight, & touch) when inspecting a food delivery. • Reject food when: • Notice signs of pests • Ice crystals in box or package of food • Torn, broken or damaged boxes, packages, or cans • Expiration/use by date has passed • Dry foods are damp
Receiving Temperature of Foods • Meat – at 41ºF or lower • Poultry – at 41ºF or lower • Fish – at 41ºF or lower • Eggs – at an air temperature of 45ºF or lower • Dairy products – at 41ºF or lower • Shellfish – at 45ºF or lower and alive • Packaged Food – at 41ºF or lower • Produce – no temperature requirements
Proper Use of a Thermometer • Clean and sanitize stem of thermometer prior to each use with alcohol • Insert thermometer into the thickest part of the food • Do not allow thermometer to touch the base of the pan • Wait a minimum of 15 seconds after the needle stops moving to take the temperature reading • Wipe thermometer stem in between foods
Calibration of a Bimetallic Stemmed Thermometer • Fill a container with ice, add drinkable water • Place thermometer stem into ice water making sure it is submerged. • Allow 30 seconds from the time the needle stops moving • Locate adjusting nut and hold securely • Rotate until needle reads 32ºF (do not remove thermometer from water while adjusting)
Storage of Food • FIFO – first in, first out • Store foods in original packaging whenever possible • Clearly label all foods with date • Don’t overload shelves or store food on floors or against walls • Store all foods a minimum of 6 inches above the floor on clean shelves or racks • Store food only in protected areas, never in rest rooms or utility rooms
Definitions • Cleaning • Involves the removal of food, residues, dirt, and grease • Sanitizing • Reduces harmful microorganisms to a level that is safe through the use of chemical sanitizing solution.
