3.1 Handwashing & Hand Hygiene Standards

Quick Answer: Proper handwashing is the primary barrier against foodborne illness. Food handlers must wash hands in a designated handwashing sink using warm water (at least 100°F/38°C), apply soap, scrub vigorously for 10–15 seconds (total wash time at least 20 seconds), rinse thoroughly, and dry with a single-use paper towel or warm-air dryer. Hands must be washed before starting work, after using the restroom, after handling raw meat, and after any potential contamination risk.

Hand hygiene is the foundation of food safety in any commercial food establishment. Human hands are the primary vector for transferring biological pathogens—including viruses like Norovirus and bacteria like Salmonella and E. coli—onto food, equipment, utensils, and surfaces. A single contaminated touch can cause an outbreak affecting many customers. Knowing how, where, and when to wash hands, alongside proper sanitizer and single-use glove usage, is mandatory for every food handler.

The Complete 5-Step Handwashing Procedure

Handwashing must be performed as a precise, multi-step process to loosen and remove transient microorganisms, oils, and debris. Skipping steps or rushing drastically reduces effectiveness.

[1. Wet (≥100°F)] ➔ [2. Apply Soap] ➔ [3. Scrub Vigorously (10-15s)] ➔ [4. Rinse Thoroughly] ➔ [5. Dry (Paper Towel/Dryer)]
                                      └───── Total Wash Time: ≥20 Seconds ─────┘

Preventing Recontamination After Washing

Once hands are clean and dry, food handlers must avoid touching dirty surfaces that immediately recontaminate them:

• Use a clean single-use paper towel to turn off manual faucet handles.
• Use a paper towel to grip the restroom door handle when exiting.
• Avoid touching garbage cans, aprons, or clothing after drying.

Handwashing Sinks: Requirements & Dedicated Usage

Where food handlers wash their hands is just as vital as how they wash them.

Dedicated Handwashing Sink Rule

• ALWAYS wash hands ONLY in designated, approved handwashing sinks.
• NEVER wash hands in three-compartment warewashing (dishwashing) sinks, food preparation sinks, or utility/mop sinks.
• NEVER use handwashing sinks for food prep, dish rinsing, tool cleaning, or storing supplies.

Essential Requirements for Handwashing Stations

Every dedicated handwashing station must be accessible and stocked with five required items:

1. Hot and Cold Running Water: Supplied through a mixing valve or combination faucet delivering water at least 100°F (38°C).
2. Hand Soap: Liquid, powder, or foam soap dispensed from a clean container.
3. Approved Drying Device: Single-use paper towels OR a warm-air hand dryer. (Cloth towels are strictly prohibited).
4. Waste Container: A trash container located near the sink for paper towel disposal.
5. Handwashing Signage: Clear signs in all employee languages reminding staff to wash hands before returning to work.

When Food Handlers Must Wash Hands

Food handlers must wash hands immediately upon entering prep areas and after any activity that could contaminate hands:

• Before:

  • Starting a work shift or returning from a break.
  • Donning single-use gloves or changing tasks.
  • Handling ready-to-eat (RTE) foods, clean equipment, or sanitized utensils.

• After:

  • Using the restroom (wash in restroom AND wash again upon entering kitchen).
  • Touching face, hair, ears, nose, mouth, body, or clothing.
  • Coughing, sneezing, blowing the nose, or using a tissue.
  • Handling raw meat, poultry, seafood, or eggs.
  • Handling garbage, trash containers, or waste matter.
  • Clearing dirty dishes, wiping tables, or handling soiled linens.
  • Handling chemicals, cleaning solutions, mops, or brooms.
  • Eating, drinking, smoking, or chewing gum/tobacco.
  • Touching service animals or aquatic animals (e.g., live lobsters).
  • Touching money, POS touchscreens, cell phones, or door handles.

Proper Use of Hand Antiseptics (Sanitizers)

Hand antiseptics provide an extra layer of protection, but must meet regulatory standards:

• NEVER Replace Handwashing: Hand sanitizers are never a substitute for soap and water. Organic material and grease protect bacteria from antiseptic chemicals.
• Apply AFTER Washing: Antiseptics must only be applied after hands have been washed and dried.
• FDA Compliance: Only use hand antiseptics complying with FDA food contact standards.
• Drying Requirement: Allow antiseptic to air-dry completely before touching food or putting on gloves.

Single-Use Glove Standards

Single-use gloves serve as a physical barrier between hands and ready-to-eat foods. However, gloves become contaminated quickly if misused.

Core Rules for Single-Use Gloves

• Wash Hands First: Hands must always be washed before putting on gloves and when changing pairs.
• Select Proper Size: Gloves should fit correctly—neither too loose nor too tight.
• Never Wash or Reuse Gloves: Gloves are for single use only. Never wash, sanitize, or re-wear gloves.
• Avoid Bare Hand Contact: Use gloves, tongs, deli paper, or spatulas when handling ready-to-eat food.

Mandatory Triggers for Changing Gloves

Food handlers must discard current gloves, wash hands, and put on a fresh pair:

1. As soon as gloves become dirty or torn.
2. Before starting a different task (e.g., switching from raw poultry to slicing tomatoes).
3. After an interruption during food prep, such as answering a telephone or taking out trash.
4. After handling raw meat, poultry, or seafood, before handling ready-to-eat food.
5. After 4 hours of continuous use on the same task.
