  17. 17. Handling Melons  Avoid using whole melons that have visible signs of decay or damaged rinds due to the increased risk that harmful bacteria may have contaminated the melon  Wash the outer surface of melons thoroughly under running cool tap water  Scrub melons with a clean produce brush before cutting  Cut melons should be consumed within 7 days Source: NFSMI

Handling Tomatoes  Wash tomatoes in water that is at least 10 degrees warmer than the internal tomato temperature  Ensure whole tomatoes are free from obvious signs of soil and skin damage  Hold tomatoes at 41 degrees or below after cutting  Cut tomatoes should be consumed or discarded within 7 days of cutting Source: NFSMI
  19. 19. Handling Leafy Greens  Do not use leafy greens with visible signs of decay or damage because there is an increased risk of the presence of harmful bacteria  When in doubt about the use of decayed or damaged product, either remove the unusable portions or do not use the leafy greens  Do not rewash packaged produce labeled “ready-to- eat”, “washed”, or “triple washed” Source: NFSMI

  26. 26. Using Gloves  Wearing gloves does NOT guarantee food safety! • Gloves can become contaminated just as easily as your hands can! • Extremely important to change gloves often!  Key Point: Wash hands before putting on new gloves! Source: ESC 20
  27. 27. Why is Food Safety Important?  Millions of people are affected each year by a foodborne illness • Majority of cases are not reported (“stomach bug”) • 2011, Center for Disease Control and Prevention estimated 48 million cases occur each year in the United States. Of those, 128,000 are hospitalized and 3,000 die of foodborne illness Source: CDC

  29. 29. How Does Food Become Unsafe?  Purchasing food from unsafe sources  Poor personal hygiene  Time-Temperature Abuse • Not cooking food adequately or to the appropriate cooking temperature  Cross Contamination • Microorganisms transferred from one surface or food to another • Using contaminated equipment/food prep surfaces • Contaminated food drips onto cooked or ready-to-eat food Source: ESC 20
  30. 30. Potential Hazards  Biological Hazards • Microorganisms such as bacteria, viruses, parasites and fungi • Plant, mushroom and seafood toxins  Chemical Hazards • Pesticides, cleaning and sanitizing chemicals, toxic metals, polishes, glass cleaners  Physical Hazards • Any foreign object that accidentally gets into food • Hair, dirt, staple, broken glass • Naturally occurring as well: bones, cartilage Source: ESC 20

  36. 36. Personal Hygiene  Treat and bandage wounds and sores immediately • When hands are bandaged the employee must wear single-use gloves Source: ESC 20
  37. 37. Preparation  Make sure that food preparation areas are clean and sanitary  Avoid cross contamination Source: ESC 20
  38. 38. Cross Contamination  Occurs when microorganisms are transferred from one food or surface to another. • Food to Food • Hand to Food • Equipment to Food  Examples: • Using the same cutting board to cut raw chicken and vegetables. • Mopping the floor and then handling a cooking utensil. • Laying a knife onto an unsanitized counter. Source: ESC 20
  39. 39. Cross Contamination  Ways to prevent cross contamination: • Wash hands properly – most important thing you can do! • Separate raw animal foods from ready-to-eat foods • Only use equipment and utensils that have been cleaned and sanitized • Use only food-grade containers to store, transport, or hold food • Touch only the surfaces of equipment and surfaces that will not come into direct contact with food • Use proper procedures for tasting foods • Think before you act! Source: ESC 20
  40. 40. Time Temperature Danger Zone  Temperature range in which disease-causing bacteria grow best and may produce toxins • 41°- 135°F  Goal is to minimize time food is left in this temperature range Source: ESC 20
  41. 41. Time Alone as a Control  Time rather than temperature used to control bacteria growth.  Serve or discard ready to eat food within four hours after being removed from temperature control. • Food must be held at appropriate temperature prior to removing from temperature control. • Hot Foods: >135°F Cold Food: <41°F  Discard food not used within the four hours. Source: ESC 20
  42. 42. Serving Safe Foods  Good Serving Practices • Use clean and sanitized utensils • Use disposable gloves appropriately • Hold: • Plates by the edge or bottom • Cups by the handle or bottom • Utensils by the handles • Keep food at the proper temperature • Keep the serving line clean and attractive • Practice good personal hygiene Source: ESC 20
  43. 43. Serving Fresh Produce  Do not store produce in direct contact with ice or water while on display  Display cut produce for a maximum of 4 hours if not in refrigeration  Use clean and sanitized tongs, spoons, and ladles so bare hands do not touch food  Keep cold foods at or below 41 degrees  Teach children not to touch food with their hands Source: ESC 20
