2 Contamination from Employees Employees can: 1.Harbor disease in body with or without symptoms 2.Carry disease on body or personal items 3.Become contaminated in the work environment

3 Food Handlers Carrying Disease Organisms with or without Symptoms From respiratory tract through coughing and sneezing From open sores, cuts, or boils From intestinal tract through hands soiled with feces Food prepared Food eaten Illness occurs

5 Employee Health 2005 Food Code require reporting, exclusion and/or restriction of employees exhibiting: Vomiting, Diarrhea, Jaundice, Sore throat with fever, or A exposed lesion containing pus such as a boil or wound

6 Employee Health Listeriosis symptoms include: Nausea* Vomiting* Headache Fever* Chills Backache *Reportable symptoms

7 Education & Awareness Employees should: Understand consequences of working when ill Be aware of symptoms that may be associated with foodborne illness Feel empowered to report illness

9 Employee Hygiene Hand hygiene Personal cleanliness Uniforms or dress codes Avoiding unsanitary actions

10 Hand Hygiene A 1993 study found that 7% of food workers carried LM on their hands

11 Hand Hygiene Key Controls Proper hand washing No bare hand contact w/ RTE food Proper hand maintenance

12 Handwashing Factors influencing effectiveness Friction to physically dislodge bacteria Water which washes bacteria from the surface and down the drain Soap or detergent to loosen the bacteria Temperature – hot water is more effective than cool water

13 Most Frequently Missed Areas During Handwashing

14 Handwashing 2005 Food Code Clean hands & exposed portions of arms Clean for at least 20 seconds Use a handwashing sink or approved automatic handwashing facility NOT in food preparation sinks or warewashing sinks

15 Handwashing Protocol 1.Rinse under clean running warm water 2.Apply recommended amount of cleaning compound (soap or detergent) 3.Rub hands together vigorously for at least 10 to 15 seconds 4.Thoroughly rinse with warm water 5.Dry hands

16 Handwashing While rubbing hands together Ensure soil is removed from underneath fingernails Create sufficient friction Ensure finger tips and areas between fingers are rubbed

17 Clean hands for at least 20 seconds

18 Handwashing When drying use one of the following methods Individual disposable towels Continuous towels systems supplying user a clean towel A heated air hand dryer

19 enterprises.net/HAND%2 0DRIER.htm Hot air dryers Benefits: Effective when operating properly and cycle is sufficiently long Less waste Drawbacks: Users may only partially dry and then wipe hands on clothes Wet hands more easily picks up microorganisms from environment

20 Paper towels Benefits: Considered most sterile of methods Friction during drying further reduces transient microorganisms from hands Can be used as barrier when turning off water and exiting door Drawbacks: Dispensers with cranks, buttons, or levers not recommended Monitoring of waste required

21 Handwashing To avoid recontamination: Use a paper towel or similar clean barrier when touching surfaces Manual faucets Handles on restroom doors

27 Bare Hands Contact Prohibited for RTE foods Prevents transfer of skin bacteria to food if properly used Use Gloves Utensils tongs, single use deli papers

28 Considerations May find their way into food product Moist and warm conditions inside glove promotes rapid bacterial growth which may escape if torn May promote complacency about adhering to good hygienic habits Gloves

29  Wear gloves that are correctly sized.  Use gloves only for their designated use.  Remove gloves whenever leaving a workstation or walk-in refrigerator.  Change gloves between handling an unclean surface or raw ingredients  Change gloves whenever contaminated  Remember gloves are not a substitute for washing hands.
