3.3 Handwashing & Proper Glove Use

Handwashing is the single most effective barrier against transferring pathogens from hands to food. The procedure taught for food manager certification follows the FDA (Food and Drug Administration) Food Code standard:

1. Wet hands and exposed forearms with warm running water
2. Apply soap
3. Vigorously scrub hands, between fingers, and under fingernails for at least 20 seconds
4. Rinse thoroughly under clean running water
5. Dry hands with a single-use paper towel or a hand dryer

Skipping any step — especially the scrub time — reduces the effectiveness of the wash and leaves pathogens on the hands.

When Handwashing Is Required

Handwashing is required at specific points, not just whenever it seems convenient. A food employee must wash hands:

• Before starting work
• After using the restroom
• After handling raw meat, poultry, or seafood
• After touching hair, face, or body
• After eating, drinking, or smoking
• After handling garbage
• After handling money
• Before putting on gloves, and between glove changes
• After any other activity that could contaminate the hands (coughing, sneezing, touching a phone, cleaning a surface, and similar)

Designated Handwashing Sinks

Handwashing must happen at a sink designated for that purpose only. A handwashing sink may not be used for food preparation or for washing dishes and equipment, and a food-prep sink or three-compartment sink may not be used as a substitute for handwashing. This separation exists because food-prep and dishwashing sinks accumulate food debris and chemical residue that would defeat the purpose of a hand wash.

The Food Code also requires each handwashing sink to supply water at a temperature suitable for effective handwashing (commonly at least 100°F/38°C) and to be stocked with soap and a means of drying hands at all times. A posted sign or poster reminding food employees to wash their hands must be placed at each handwashing sink used by employees, so the requirement stays visible during a busy shift rather than only during training.

No Bare-Hand Contact With Ready-to-Eat Food

The FDA Food Code prohibits bare-hand contact with ready-to-eat (RTE) food — food that will be served without any further cooking step capable of killing pathogens. Instead, employees must use one of the following barriers:

• Suitable utensils (tongs, spatulas, deli spoons)
• Deli paper or single-use tissue
• Single-use gloves

This rule exists because even well-washed hands can still transfer pathogens such as Norovirus or Hepatitis A virus onto food that will never be cooked before a customer eats it.

Proper Glove Use

Gloves are a useful barrier, but they are not a substitute for handwashing, and misusing them can create a false sense of safety that is worse than using clean bare hands with utensils. Key rules:

• Wash hands before putting on gloves — contaminated hands contaminate the inside, and quickly the outside, of the glove
• Change gloves between different tasks, for example switching from handling raw chicken to plating a ready-to-eat salad
• Change gloves immediately after any contamination event, such as dropping a glove, touching a non-food surface, or handling garbage
• Change gloves at least every 4 hours during continuous use on the same task, or per a stricter timeframe set by the local regulatory authority
• Never wash and reuse single-use gloves — they are designed for one use, and washing does not reliably remove contamination or restore the glove's integrity

Glove Material Matters

Not every single-use glove is appropriate for every kitchen. Latex gloves can trigger allergic reactions in employees and, through cross-contact, in customers with latex sensitivities, so many operations standardize on nitrile or vinyl gloves for food-contact tasks instead. A manager should know what glove material the establishment stocks, why it was chosen, and whether any staff member has reported a latex sensitivity that needs to be accommodated.

Hand Sanitizer Is Not a Substitute

Alcohol-based hand sanitizer can supplement, but never replace, proper handwashing. Under the Food Code, a hand antiseptic may only be applied after hands have already been washed correctly; it is not an approved alternative when a required handwash has been skipped, and it does nothing to remove visible soil or organic debris from the hands.

Common Exam Traps

Two mistakes show up repeatedly in real kitchens and on the exam:

• Treating gloves as a substitute for handwashing — gloving over unwashed hands, or never changing gloves between raw and ready-to-eat tasks
• Using the wrong sink — quickly rinsing hands in the three-compartment sink or the food-prep sink instead of walking to the designated handwashing station

A manager who observes either of these should treat it as an immediate coaching moment, not a minor inconvenience, because both create a direct path for pathogens to reach ready-to-eat food.
