If you wash your boards properly after every use, plastic chopping boards are not automatically more hygienic than wooden ones. In fact, several food safety studies show that quality hardwood and bamboo boards can hold fewer live bacteria after 12–24 hours than heavily scored plastic boards, because wood absorbs moisture and traps bacteria away from the food surface.
Plastic vs wooden chopping boards: what actually keeps your kitchen safer?
So what is the best chopping board for a hygienic kitchen? For most home cooks in the UK, a large wooden or bamboo board for dry foods and a separate plastic board for raw meat and fish is the most practical and hygienic mix.
The key is not just the material but how you use it:
- Separate boards for raw meat, cooked food and fruit or bread
- Hot water and washing up liquid after every use
- Replacement of badly scored plastic boards every 1–2 years
- Oiling wooden boards every 4–8 weeks so they stay sealed and smooth
In everyday kitchens, a well cared for wooden board is often more hygienic after 12–24 hours than an old plastic board with deep knife grooves that are hard to clean.
How bacteria behave on plastic and wooden cutting boards
To decide between plastic and wooden chopping boards, it helps to understand what actually happens to bacteria on the surface.
Plastic chopping boards
- Easy to sanitise on day one: New plastic boards can be scrubbed very clean and even put in a dishwasher at 60–70°C.
- Knife marks build up quickly: After a few months of daily use, especially with heavy chef knives, plastic boards can develop hundreds of knife grooves.
- Grooves trap food and moisture: Those tiny cuts can hold raw meat juices and bacteria that ordinary washing sometimes misses.
- Needs frequent replacement: For busy home kitchens, a heavily used plastic meat board often needs replacing every 12–18 months.
Wooden and bamboo chopping boards
- Natural antibacterial effect: Studies on hardwoods and bamboo show that bacteria on the surface often die off within a few hours as moisture is drawn into the board.
- Self healing to a point: Good quality boards made from Moso bamboo or acacia close up light knife marks better than soft plastic.
- Need hand washing: Wood should not be soaked or put in the dishwasher, but can be washed with hot water and washing up liquid.
- Can last 5–10 years: A 45x35 cm wooden board that is oiled regularly can stay safe and smooth for many years.
The result? Plastic can be easier to disinfect on day one, but after a year of heavy use, a well maintained wooden board is often the more hygienic choice for most foods.
How to keep your chopping boards hygienic every day
Whether you choose plastic, bamboo or acacia, these simple habits matter more than the material alone.
1. Use colour or material coding
- Keep one dedicated plastic board for raw meat and fish.
- Use a wooden or bamboo board for bread, fruit, veg and cooked foods.
- Never use the same board for raw chicken and ready to eat salad without washing it thoroughly in between.
2. Clean immediately and thoroughly
- Wash boards within 10 minutes of use so food does not dry on.
- Use very hot tap water with washing up liquid and a stiff brush or sponge.
- Rinse well and stand upright to dry fully on both sides.
3. Deep clean and refresh surfaces
- Once a week, sprinkle coarse salt on wooden boards, scrub with half a lemon, leave for 5 minutes and rinse.
- For plastic, check for deep cuts; if you can feel a groove with your fingernail, that area is harder to clean.
- Replace plastic boards as soon as they are badly scarred or stained.
4. Oil wooden boards regularly
At Deer & Oak we pre oil our boards so they arrive ready to use, but they still need simple care.
- Every 4–8 weeks, apply a thin layer of food safe mineral oil or board balm.
- Use a soft cloth, leave for 20 minutes, then wipe off any excess.
- This helps seal the surface, reduces water absorption and keeps the board smoother and easier to clean.

FAQ: are plastic chopping boards more hygienic than wooden?
Q: Are plastic chopping boards always more hygienic than wooden boards?
A: No. New plastic boards are easy to disinfect, but once they have deep knife marks they can trap bacteria. Quality wooden and bamboo boards, such as Moso bamboo and acacia, draw moisture away from the surface, which can reduce live bacteria after a few hours if the board is washed and dried properly.
Q: How often should I replace my plastic cutting board for hygiene?
A: If you use a plastic board daily for raw meat, check it every few months and replace it roughly every 12–18 months, or sooner if it has deep grooves you can feel with your fingernail. Those cuts are difficult to clean fully and are the main hygiene concern with older plastic boards.
Q: Are bamboo chopping boards safe for raw meat?
A: Bamboo boards can be used for raw meat if you scrub them straight away with hot water and washing up liquid and let them dry fully. Many people still prefer a dedicated plastic board for raw meat and use bamboo for veg and cooked foods, which is a simple way to reduce cross contamination in a busy kitchen.
Q: How long will a wooden chopping board last if I look after it?
A: A well made 45x35 cm wooden or bamboo board that is washed by hand and oiled every 4–8 weeks can last 5–10 years of regular home use. That is much longer than most plastic boards used daily for meat, which often need replacing after 1–2 years for hygiene reasons.
So, which chopping board should you choose?
If your priority is hygiene, the answer is not "plastic or wooden" but how you combine and care for both.
