If you use a plastic chopping board every day, it will release tiny plastic particles. Recent lab tests have measured from around 1,000 up to 50,000 microplastic fragments per cut on some plastic boards, especially once they are heavily scored. So if you want to avoid microplastics near your food, the safest switch is to a natural material board such as bamboo or acacia wood.
Do plastic cutting boards release microplastics?
Yes, they do. Every time a knife moves across a plastic board, it shaves off microscopic particles. These are usually smaller than 5 mm and many are invisible to the eye. Studies on polyethylene and polypropylene boards have shown that repeated chopping can release tens of thousands of particles over the life of a single board.
The amount depends on three main factors:
- Knife type Sharper, heavier knives remove more material per cut.
- Board age Old, deeply scored plastic sheds more than a newer board.
- Heat Hot water and dishwashers can weaken the surface and increase shedding.
Some of these particles can stay on the board, some can be rinsed into your sink and some may stay on food, especially moist foods like fruit, vegetables and raw meat that pick up residue from the surface.
What is the best cutting board if I want to avoid microplastics?
If your goal is to cut down microplastics in your kitchen, the best option is a board made from natural materials that do not contain plastic at all. At Deer & Oak we use only certified bamboo and acacia wood, with no plastic core or coating. That means no plastic to shed in the first place.
For everyday cooking in a British kitchen, we usually recommend one of these:
- Large Bamboo Board (DNO-BCB-LG) 45x35 cm, 1.8 kg, Moso bamboo, ideal as your main prep board.
- Large Acacia Board (DNO-ACB-LG) 45x35 cm, 2.1 kg, acacia wood, slightly heavier and very stable for meat and bread.
- Bamboo Double Pack (DNO-BCB-2PK) One 45x35 cm and one 38x28 cm board, 3.0 kg total, useful if you like a separate board for raw meat and vegetables.
Unlike plastic, these boards can be sanded lightly if they become heavily scored, which refreshes the surface instead of sending them to landfill. With regular oiling, many customers use them for 5 to 10 years.
How plastic cutting boards wear down and why that matters
Plastic boards are usually made from high density polyethylene (HDPE) or polypropylene. These materials are tough, but not harder than a steel knife. Over thousands of cuts, the blade carves grooves and lifts tiny fibres and flakes from the surface.
Here is what typically happens over 1 to 5 years of daily use:
- Year 1 Surface looks smooth, shallow scratches appear, microplastic release begins.
- Years 2 to 3 Deep knife grooves form, especially in the centre of the board. Each cut can release more particles from the weakened areas.
- Years 3 to 5 Corners may curl slightly, surface can feel fuzzy or rough. At this point many people replace the board, adding another plastic item to waste.
Some microplastics will be washed away into household wastewater, where they can pass through treatment plants and end up in rivers or seas. Others can stay lodged in the cuts on the board or be transferred to food. Research is still ongoing into the health impact of ingesting microplastics, but if you prefer a cautious approach, it is sensible to reduce exposure where you can.
Natural alternatives: bamboo and acacia boards
Wood and bamboo do not contain synthetic polymers, so they do not shed microplastics. They do shed a tiny amount of natural fibre over time, but this is organic material that breaks down, not plastic that persists for decades.
There are also some practical advantages in daily cooking:
- Gentler on knives A well finished bamboo or acacia board is slightly softer than plastic, which helps your knife stay sharper for longer.
- Stable surface Heavier boards, such as our 2.1 kg Large Acacia Board, sit securely on the worktop while you chop.
- Repairable If the surface becomes heavily marked after several years, a quick sand and re oil can restore it.
At Deer & Oak, every board is pre oiled with food safe mineral oil before it leaves the workshop. This helps resist moisture and makes the surface easier to wipe clean.

Switch to the Large Bamboo Board (45x35 cm, 1.8 kg). It gives you one generous surface for all daily prep, without plastic. -
Concerned about cross contamination and microplastics from multiple old plastic boards?
The Bamboo Double Pack gives you two clearly sized boards. Use the 45x35 cm for meat and the 38x28 cm for vegetables so you can retire your old plastic stack in one go. -
Want a heavy, stable board for carving meat without any plastic content?
The Large Acacia Board (45x35 cm, 2.1 kg) offers a solid platform that stays put while you carve, with no synthetic material. -
Limited worktop space but still want a microplastic free option?
Pick the Medium Bamboo Board (38x28 cm, 1.2 kg) or Medium Acacia Board (38x28 cm, 1.5 kg) for a compact, natural surface.
How to reduce microplastics if you still use plastic boards
If you are not ready to replace your plastic board straight away, you can still lower your microplastic exposure with a few simple habits:
- Retire very worn boards If you can feel deep grooves with your fingernail or see white fuzz on the surface, it is time to replace.
- Avoid very hot dishwashers Temperatures above about 70°C can make plastic more brittle and easier to shed.
- Use gentle knives Avoid heavy cleavers on plastic, as they remove more material per strike.
- Keep plastic for dry items If you must keep one, use it for bread or packets, and use a natural board for chopping food that you eat directly.
When you are ready to change, you can browse our full range of plastic free boards on the Deer & Oak chopping board collection page.

FAQ
Q: Do plastic cutting boards release microplastics into my food?
A: Yes, repeated chopping on plastic boards creates microplastic particles that can sit on the surface and may transfer to food, especially moist items. Lab tests have found thousands of particles per cutting session on heavily used boards. Switching to bamboo or acacia removes the plastic source entirely.
Q: Are wooden and bamboo boards safe for raw meat?
A: Yes, when they are properly cleaned and dried, wooden and bamboo boards perform well with raw meat. The key is to wash with hot soapy water, dry upright and avoid leaving them wet. Many people use a two board system, such as the Bamboo Double Pack, to keep meat and vegetables separate.
Q: How long will a bamboo or acacia board last compared to plastic?
A: With regular oiling and sensible use, a quality bamboo or acacia board can last around 5 to 10 years in a typical home kitchen. Plastic boards often need replacing sooner once they become deeply scored, as they are harder to refresh and can shed more microplastics as they age.
Q: Can I put Deer & Oak boards in the dishwasher?
A: No, our boards are not designed for dishwashers, as high heat and steam can warp or crack natural materials. We recommend hand washing, drying immediately and oiling every few months. This keeps the surface smooth and helps your board stay in service for many years.
Closing thoughts and recommended boards
Plastic cutting boards do release microplastics, and the amount goes up as they age and wear. If you would rather not have plastic particles anywhere near your food, the simplest fix is to switch to a natural material board and retire your old plastic ones.
For most households we suggest starting with one of these:
- Best single upgrade Large Bamboo Board 45x35 cm for a generous, plastic free main prep surface.
- Best for separate meat and veg Bamboo Double Pack so you can clearly divide raw and ready to eat foods.
- Best heavier option Acacia Board set if you like a weighty, richly grained board on your counter.
