If you want to prevent cross contamination in your kitchen, the most effective setup is to use at least two separate chopping boards: one reserved for raw meat and fish, and one for ready to eat foods like bread, fruit and salads. In practice, a colour or material system works best, such as using a darker 45x35cm board for raw proteins and a lighter 38x28cm board for vegetables and cooked food.
Why separate chopping boards matter for kitchen hygiene
Cross contamination happens when bacteria from raw meat, poultry or fish spread to ready to eat food. A single board for everything makes this far more likely, even if you wash it between uses. Tiny knife marks can hold moisture and bacteria, and a quick wipe rarely reaches them all.
The most reliable way to cut the risk is to separate by task. At Deer & Oak we usually suggest:
- One larger board (around 45x35cm) for raw meat, poultry and fish
- One medium board (around 38x28cm) for fruit, veg, bread and cooked food
- Optional: a third board for strong flavours like onion, garlic and chilli
This is why our Bamboo Double Pack and our carbonised and acacia ranges are sized to work as clear, dedicated stations for different food types.
Wood vs plastic: which is best to prevent cross contamination?
Both wood and plastic can be safe if they are used and cleaned properly, but they behave differently.
Why many home cooks choose bamboo or acacia
- Less knife scarring than soft plastic so fewer deep grooves where bacteria can sit
- Gentle on knives which helps your blades last longer
- Natural look that can stay on the worktop as a prep station or serving board
Bamboo in particular is dense and light. Our Large Bamboo Board DNO-BCB-LG is 45x35cm but only 1.8kg, so it feels stable yet still easy to move to the sink. Acacia is a little heavier and richer in colour, which many people like to reserve for serving cooked meats or cheese.
When plastic might be better
- If you run your boards through a dishwasher at 60 to 75°C after every use
- If you want a very cheap, colour coded set purely for raw meat
For most home kitchens that prefer natural materials on show, a two or three board wooden system works very well, as long as you wash with hot soapy water and let the boards dry upright every time.
How to set up a simple anti cross contamination board system
Here is a practical layout that matches our most popular Deer & Oak sizes:
-
Raw meat and fish board
Use a darker or clearly designated board. Our Carbonised Bamboo Board DNO-CBB-LG in 45x35cm is ideal for this. The 1.9kg weight keeps it steady when trimming larger joints or whole chickens. -
Fruit, veg and cooked food board
Choose a lighter board, such as the Medium Bamboo Board DNO-BCB-MD at 38x28cm and 1.2kg. Use this only for salad, fruit, bread and cooked items. -
Optional carving or serving board
If you often rest roasts or slice bread at the table, a dedicated acacia board like the Large Acacia Board DNO-ACB-LG at 45x35cm can stay away from raw meat completely.
If you want everything in one go, our board sets combine these sizes so you can assign each one a clear role on day one.

Cleaning and care to keep bacteria under control
Even the best chopping board system only works if the boards are cleaned properly.
- Wash straight away in hot water with washing up liquid for at least 20 to 30 seconds per side
- Rinse well so no soap remains in the grain
- Dry upright so air can circulate around both faces
- Sanitise occasionally with a solution of 1 tablespoon of white vinegar in 500ml of water, wiped on and left for 5 minutes before rinsing
- Re oil every 4 to 6 weeks with a food safe mineral oil or board oil to keep moisture out of the fibres
All Deer & Oak boards arrive pre oiled so you can start using them straight away. With regular washing and oiling, a board can last 5 to 10 years in a busy family kitchen.

FAQ
Q: How many chopping boards do I really need to prevent cross contamination?
A: For most homes, two boards is the minimum: one for raw meat and fish, and one for fruit, vegetables and cooked foods. If you cook a lot, a third board for bread and serving can help keep smells and stains away from your prep boards.
Q: Which Deer & Oak board is best to use as my raw meat board?
A: The Carbonised Bamboo Board DNO-CBB-LG at 45x35cm works very well because its darker colour is easy to remember as the “raw” board. The 1.9kg weight keeps it steady when trimming joints or portioning chicken, and you can pair it with a lighter bamboo or acacia board for ready to eat foods.
Q: How often should I replace my chopping boards for hygiene reasons?
A: If you care for them properly, quality bamboo and acacia boards can last 5 to 10 years. Replace a board sooner if you see deep grooves, cracks or warping that you cannot sand out, as these areas are harder to clean thoroughly.
Q: Can I use one side of a board for meat and the other for vegetables?
A: You can, but it is easy to forget which side is which, especially on a busy evening. For better safety and less thinking, we recommend separate physical boards, such as the two sizes in our Bamboo Double Pack, clearly assigned to different food groups.
