How to wash your hands

The kitchen was spotless. Staff wore gloves, hairnets, and clean uniforms. Yet a routine inspection traced a foodborne illness outbreak back to this very place. The cause wasn’t spoiled ingredients or dirty equipment it was hands. More specifically, the belief that gloves alone were enough. That belief is one of food safety’s biggest sacred cows.

The Sacred Cow: “Gloves Are Safer Than Clean Hands”

In many food environments, gloves are treated as a substitute for handwashing. They are not. Gloves become contaminated just as easily as bare hands and, when not changed correctly, can spread bacteria faster because workers feel “protected” and touch more surfaces. Proper handwashing before putting on gloves and between tasks is non-negotiable. Gloves are a barrier, not a cure.

Why Handwashing Matters

Hands are the main vehicle for transferring harmful microorganisms such as E. coli, Salmonella, and Norovirus. In food handling, a single lapse—after using the toilet, touching raw food, handling waste, or using a phone can contaminate dozens of meals.

Effective handwashing:

Removes visible dirt and grease
Reduces harmful bacteria and viruses
Breaks the chain of cross-contamination

Proper Handwashing: The Food Safety Standard

From a food safety standpoint, handwashing must be:

Done with running water and soap
Last at least 20 seconds
Include palms, backs of hands, between fingers, thumbs, and under nails
Finished with proper drying using a clean towel or air dryer

Wet hands spread microbes more easily than dry ones, making drying an essential step—not an optional one.

When Hands Must Be Washed

Food handlers should wash hands:

Before starting work
Before handling ready-to-eat food
After using the toilet
After handling raw food
After touching waste, phones, money, or surfaces
After coughing, sneezing, or touching the face
Before and after wearing gloves

Hand Sanitizers: Useful but Limited

Alcohol based hand sanitizers can reduce microbes but do not replace handwashing, especially when hands are visibly dirty or greasy. In food safety systems, sanitizers are a backup not the main defense.

Hygiene Is a System, Not a Symbol

Clean uniforms, gloves, and shiny kitchens look good, but food safety is built on behavior. Handwashing remains the single most effective, low-cost control measure in preventing foodborne illness. Challenging sacred cows like overreliance on gloves—is essential for truly safe food.
