Food Safety: How Food Handlers Can Contaminate Food
How People Can Contaminate Food
- Food handlers can contaminate food in several ways:
- Touching their face.
- Sneezing or coughing.
- Having a wound that contains a pathogen.
- Having contact with someone who is sick.
- Not washing hands after using the restroom (fecal-oral route of contamination).
- Having a foodborne illness or symptoms like diarrhea, vomiting, or jaundice.
- Some illnesses can be spread before symptoms appear (e.g., hepatitis A) or after symptoms end (e.g., norovirus).
- Carriers are people who carry pathogens and infect others without getting sick themselves.
Actions That Can Contaminate Food
- Specific actions that can cause foodborne illness:
- Scratching the scalp or running fingers through hair.
- Sneezing or coughing into hands.
- Wearing or touching dirty clothing or aprons.
- Rubbing an ear.
- Wiping or touching the nose.
- Touching a pimple or an infected wound.
- Spitting.
Managing Personal Hygiene Policies
- As a manager, you're responsible for food safety, including:
- Creating good personal hygiene policies.
- Revising policies periodically to stay updated.
- Training and retraining food handlers on these policies.
- Supervising food safety practices.
- Modeling correct behavior.
Handwashing
- Importance: Handwashing is the most important part of personal hygiene.
- Location: Hands should only be washed in a sink designed for handwashing, never in food prep or dishwashing sinks.
- Five-Step Process:
- Wet hands and arms with warm running water.
- Apply enough soap to build up a good lather, following the manufacturer's recommendations.
- Scrub hands and arms vigorously for 10 to 15 seconds, cleaning fingertips, under fingernails, and between fingers.
- Rinse hands and arms thoroughly under warm running water.
- Dry hands and arms with a hand dryer or a single-use paper towel.
- Use a paper towel to turn off the faucet and open the door to avoid recontamination.
- Action Needed: If food handlers aren't washing their hands correctly:
- Dispose of contaminated food.
- Clean and sanitize any utensils and equipment that may have been contaminated.
- Retrain or coach those food handlers.
When to Wash Hands
- Always wash your hands:
- Before preparing food or working with clean equipment and utensils.
- After using the restroom.
- After handling soiled items and before touching clean items.
- After touching your body or clothing.
- After handling raw meat, poultry, or seafood.
- After taking out garbage.
- After sneezing or coughing, blowing your nose, or using a handkerchief or tissue.
- After eating, drinking, chewing gum, or using tobacco products (including e-cigarettes).
- After handling money.
- After handling chemicals that can make food unsafe.
- After touching service or aquatic animals.
- After leaving the kitchen or food prep area and then returning to it.
- When changing tasks.
- Before putting on single-use gloves.
- After touching electronic devices.
- Food handlers should try to wash their hands every time they touch anything that could possibly contaminate them.
Hand Antiseptics (Hand Sanitizers)
- Hand antiseptics can reduce pathogens but are not a substitute for handwashing.
- Only use hand antiseptic after handwashing, never in place of it.
- Wait for the antiseptic to dry before touching food or equipment.
- Ensure the hand antiseptic complies with CFR and FDA standards.
Hand Care
- Fingernails:
- Keep nails short, clean, and filed to prevent pathogenAccumulation
- Nail polish and false fingernails should not be worn unless single-use gloves are used
- Wounds:
- Cover infected wounds, cuts, and boils to prevent pathogens from contaminating food.
- Wounds on the hand, finger, or wrist: use an impermeable cover (finger cot or bandage) and then a single-use glove.
- Arm wounds: cover completely with an impermeable cover.
- Wounds on other parts of the body: cover with a dry, durable, tight-fitting bandage.
Gloves
- Use gloves approved for food service.
- Ensure gloves are single-use only, never washed or reused.
- Provide a variety of sizes for staff.
- Consider providing non-latex gloves due to sensitivities.
How to Use Gloves
- Gloves are not a replacement for correct handwashing.
- Always wash hands before putting on gloves when starting a new task.
- Put gloves on carefully, holding them by the edge and avoiding touching the glove as much as possible.
- Do not blow into gloves or roll them up.
- Check gloves for rips or tears once they're on.
When to Change Gloves
- Change gloves:
- As soon as they become dirty or torn.
- Before beginning a different task.
- If you get interrupted during a task.
- After handling raw meat, seafood, or poultry, and before handling ready-to-eat food.
- After four hours of continuous use.
- Avoid touching ready-to-eat food with bare hands, especially if serving a high-risk population.
- Exceptions:
- Washing produce.
- Handling ready-to-eat ingredients for a dish that will be cooked to the correct internal temperature (at least 145∘F or 63∘C if the dish does not contain raw meat, seafood, or poultry).
- If the dish contains raw meat, seafood, or poultry, cook the food to the required minimum temperature of those raw items.
Personal Cleanliness and Hygiene
- Shower or bathe before work.
- Follow a dress code to minimize pathogens on clothing.
- Wear a clean hat or hair covering in food prep areas.
- Limit hair accessories to those that keep hair out of food.

Jewelry

- Some managers may require removing other jewelry like necklaces, earrings, and facial jewelry.
- Servers can wear jewelry if allowed by company policy.
Eating, Drinking, Smoking, and Chewing Gum or Tobacco
- Saliva contains pathogens that can cause foodborne illness.
- Eating, drinking, smoking, chewing gum, and using tobacco products can transfer pathogens to hands or food.
- Only do these things in designated areas.
- If drinking in food or food prep areas, use a container with a sip lid or a lid and straw.
