The Foundational Rule: Master Proper Handwashing

Handwashing is the single most important action you can take to prevent the spread of foodborne illness. Germs can survive in many places and are easily transferred to food and kitchen surfaces from hands. Knowing when and how to wash your hands correctly is critical.

When to Wash Your Hands

  • Before you start preparing or handling any food.
  • After handling raw meat, poultry, seafood, or eggs.
  • After using the toilet, smoking, sneezing, coughing, or touching your face or hair.
  • After handling garbage, dirty dishes, or cleaning chemicals.
  • After touching pets or livestock.
  • Before eating or serving food.

How to Wash Your Hands Properly

Follow these steps to effectively remove germs:

  1. Wet your hands with clean, warm, running water and apply soap.
  2. Lather hands by rubbing them together with the soap. Make sure to lather the backs of your hands, between your fingers, and under your nails.
  3. Scrub your hands for at least 20 seconds.
  4. Rinse your hands well under clean, running water.
  5. Dry your hands using a clean, single-use paper towel or a heated-air hand-drying device. If in a professional setting, use the designated handwashing sink.

The Cross-Contamination Conundrum: Separate for Safety

Cross-contamination is the transfer of bacteria from one food, surface, or piece of equipment to another. This is one of the most common causes of food poisoning, but it is entirely preventable with careful personal practices.

In the Kitchen: Tools and Surfaces

  • Use separate cutting boards: Designate one cutting board for raw meats, poultry, and seafood, and a different one for ready-to-eat foods like fruits, vegetables, and bread. Many professional kitchens use color-coded boards for this purpose.
  • Wash utensils thoroughly: Knives, tongs, and other utensils used with raw ingredients must be washed with hot, soapy water before being used with cooked or ready-to-eat foods.
  • Clean as you go: Immediately clean and sanitize any surface that has come into contact with raw food or its juices.

In the Refrigerator: Proper Storage

  • Store raw below ready-to-eat: Always store raw meat, poultry, and seafood in sealed containers on the bottom shelf of your refrigerator to prevent juices from dripping onto other foods.
  • Keep covered: Use airtight containers to store leftovers and ready-to-eat items to prevent contact with raw ingredients.

Table: Safe vs. Unsafe Food Handling Practices

Action Safe Practice Unsafe Practice
Hand Hygiene Washing for 20 seconds with soap and water A quick rinse with water only
Equipment Use Using separate, color-coded cutting boards for raw and cooked foods Using the same board for raw chicken and fresh salad without cleaning
Storage Keeping raw meat in a sealed container on the bottom fridge shelf Storing raw meat above fresh vegetables or cooked leftovers
Managing Illness Staying home for 48 hours after symptoms of vomiting/diarrhea cease Handling food while experiencing symptoms
Personal Appearance Tying back hair and wearing a clean apron Hair hanging loose over food preparation surfaces
Touching Items Using a towel to turn on faucets after washing hands Touching phones or other personal items before returning to food prep

The Personal Factor: Fitness to Handle Food

Your physical health and appearance are crucial components of personal hygiene for food safety. Knowing when you are well enough to handle food and maintaining clean clothing and hair are basic yet vital practices.

If You Are Sick

If you are suffering from symptoms like vomiting or diarrhea, you should not handle food. Inform your supervisor if you work in a food business and avoid returning to work until you are symptom-free for at least 48 hours to prevent contaminating food with pathogens.

Cleanliness and Attire

  • Hair and Nails: Always tie back or cover long hair and keep fingernails short and clean. Avoid false nails or nail polish.
  • Clothing: Wear clean clothes and a clean apron dedicated to food preparation. Do not wipe your hands on your apron or clothes.
  • Jewellery: Remove all loose jewellery, as it can harbor bacteria and potentially fall into food.

The Mindful Chef: Behavioral Hygiene

Beyond the basic physical actions, personal hygiene extends to your behavior and awareness while in the kitchen.

The "Don't Touch" List

  • Avoid touching your face, hair, or skin while preparing food. If you do, wash your hands immediately.
  • Never eat, chew gum, or smoke over food or food preparation surfaces.
  • Avoid sneezing or coughing over food. If you must, turn away and cover your mouth and nose, then wash your hands thoroughly.
