How to Sanitise a Kitchen Properly After Raw Chicken

Raw chicken is one of the highest-risk food items handled in a domestic kitchen. It carries Campylobacter and Salmonella — the two most common causes of foodborne illness in Australia — at significant rates. The risk is not theoretical: approximately 220,000 Australians experience campylobacteriosis annually, and contamination from raw chicken is a leading source.

What makes raw chicken particularly challenging is how far the contamination spreads during handling. Most people clean the chopping board and the knife and consider the job done. But contamination from raw chicken is deposited on a much wider area — and on much higher-touch surfaces — than most people realise.

This guide covers exactly what needs to be sanitised, why, and the correct sequence.

Understanding the Contamination Spread

Before covering the method, it's worth understanding what actually happens when raw chicken is handled in a kitchen.

When you handle raw chicken, the bacteria from the surface transfer to your hands. Every surface your hands subsequently touch becomes contaminated: the bench around the chicken, the tap handles when you wash your hands, the dishwashing liquid bottle you squirt, the drawer handles you open for the knife, the door of the bin you open to dispose of packaging.

Research has demonstrated that raw chicken handling can contaminate 6–12 surfaces in a typical kitchen preparation sequence — many of which are then touched repeatedly during the rest of meal preparation and during serving.

The kitchen cloth or sponge is a particular risk. Using a cloth to wipe the bench after raw chicken handling, then using the same cloth elsewhere in the kitchen, spreads Campylobacter to the next surface it touches.

The Correct Post-Chicken Kitchen Sanitisation Sequence

Step 1: Dispose of Packaging Immediately

Chicken packaging is often the most heavily contaminated surface. Dispose of it immediately in the bin — don't set it on the bench while you deal with other things.

Once the packaging is in the bin, close the bin lid.

Step 2: Wash Hands Thoroughly

Before touching anything else, wash hands with soap and warm water for at least 20 seconds. This is not a quick rinse — it's a thorough scrub of every surface of the hands including between the fingers and under the nails.

Dry with a clean paper towel or a clean, dedicated hand towel. Don't use the general kitchen cloth.

Step 3: Clean the Primary Contamination Zone

The chopping board, knife, and immediately surrounding bench area are the primary contamination zone. Clean these first.

Chopping board: Wash the board in hot soapy water, scrubbing all surfaces. Then sanitise with a food-safe sanitiser (a diluted bleach solution — 1 teaspoon of bleach in 1 litre of water — or a TGA-registered food surface sanitiser spray). Leave the sanitiser on for 1–2 minutes, then rinse thoroughly with water. Bleach must not be left on food contact surfaces without rinsing.

A separate, dedicated board for raw meat is the most effective prevention — it prevents cross-contamination with vegetables and ready-to-eat foods regardless of how well the board is cleaned between uses. Colour-coded boards (red for raw meat) are the food service standard.

Knife: Wash in hot soapy water or the dishwasher (dishwasher sanitising temperatures kill bacteria more effectively than hand washing). If hand washing, wash the blade carefully to avoid injury.

Bench surface: The immediate area around where the chicken was prepared — including any splatter area — needs to be:

1. Cleaned with hot soapy water and a clean cloth or paper towel
2. Sanitised with food surface sanitiser or diluted bleach solution
3. Left for the required contact time (check the product — typically 30–60 seconds)
4. Rinsed if using bleach; no rinsing required for most spray sanitisers

Step 4: Sanitise the Secondary Contamination Zone

This is the step most people miss entirely. Identify and sanitise every surface your hands touched after handling the raw chicken:

Tap handles: Both hot and cold. These are touched immediately after handling chicken — before washing hands — in most preparation sequences. Wipe with sanitiser.

Dishwashing liquid bottle (or soap dispenser): Touched to squeeze soap. Wipe with sanitiser.

Sink basin surround: The area around the tap and the sink basin edge.

Bin lid/pedal: If you lifted a lid or pressed a pedal.

Any drawer or cupboard handles opened to get tools.

The refrigerator handle: If you returned items to the fridge during preparation.

Any other surface touched between starting to handle the chicken and completing the hand wash.

This secondary sanitisation is what's almost universally skipped, and it's why cross-contamination from raw chicken preparation is so common in domestic kitchens.

Step 5: Deal with Cloths and Sponges

Any cloth or sponge used to clean after raw chicken should not be reused in the kitchen that evening without being laundered or replaced.

Best practice: Use paper towels for the initial clean-up after raw chicken, dispose of them, and then sanitise the surface. This avoids the sponge/cloth contamination problem entirely.

If using a cloth: Wash in the hottest cycle of the washing machine after the kitchen clean-up. Do not leave the cloth in the kitchen overnight.

Kitchen sponges: Sponges are among the most contaminated objects in most kitchens because they are porous, retain moisture, and are rarely cleaned or replaced frequently enough. Research consistently shows that kitchen sponges carry high bacterial loads. After raw chicken clean-up, either replace the sponge or microwave it damp for 60 seconds (this kills most bacteria in the sponge — research from the University of Florida and others has validated this approach, though it doesn't eliminate all strains). Replace kitchen sponges at least monthly.

Step 6: Wash Hands Again

After all the cleaning and sanitising, wash hands thoroughly again. The cleaning process itself involves handling contaminated surfaces.

What Actually Kills Campylobacter and Salmonella

Heat: Both pathogens are killed by heat — this is why fully cooking chicken is non-negotiable. Cooking to an internal temperature of 75°C throughout kills both.

Bleach: A diluted bleach solution (1 teaspoon per litre of water) is highly effective. Must be used at correct dilution — too weak is ineffective; residue at high concentration is harmful.

Commercial food surface sanitisers: TGA-registered food surface sanitisers (quaternary ammonium compound based, or similar) are effective and don't require rinsing on food contact surfaces. These are what commercial kitchens use.

Dishwasher: Dishwasher temperatures (typically 60–70°C in the wash cycle) kill both Campylobacter and Salmonella. Items that can safely go through the dishwasher are well-sanitised by doing so.

What doesn't kill them reliably:

• Cold or lukewarm water alone
• Vinegar (has antibacterial properties but is not a registered disinfectant for this purpose)
• Essential oil-based "antibacterial" sprays
• Air drying (bacteria survive on dry surfaces for hours)

Cross-Contamination: The Bigger Picture

Raw chicken cross-contamination in the kitchen is the source of a significant proportion of Australian foodborne illness. The prevention principles:

Dedicated boards: Separate boards for raw meat and everything else.

Wash hands every time before touching something new: During any meat preparation, assume your hands are contaminated and wash each time you shift tasks.

Never defrost chicken on the bench: Defrost in the refrigerator (overnight) or in cold water in a sealed bag. Bench defrosting allows bacteria to multiply in the outer layers of the chicken while the centre is still frozen.

Refrigerate chicken correctly: Below 4°C. The temperature between 5°C and 60°C is the "danger zone" for bacterial growth.

Cook to temperature, not colour: A chicken breast that looks cooked may not have reached 75°C in the thickest part. Use a meat thermometer.
