If you want to know whether bamboo cutting boards actually reduce bacteria, several peer reviewed studies give a clear answer: bamboo and other wooden boards can cut bacterial survival by up to 99% within 3 to 12 hours compared with plastic, and hard, tight grained species like moso bamboo tend to absorb less moisture and scar less, which supports lower bacterial counts when cleaned correctly. In practical terms, a well cared for moso bamboo board, such as a 45x35cm Deer & Oak board, helps reduce E. coli and Salmonella survival compared with many plastic boards that keep bacteria on the surface.
What studies show bamboo and wooden boards reduce bacteria?
Several well known microbiology and food safety studies have looked at how bacteria behave on cutting boards. While not every paper tested bamboo specifically, the mechanisms they describe apply directly to high density, eco friendly moso bamboo cutting boards.
-
Ak et al., 1994, University of Wisconsin
Researchers compared wooden and plastic cutting boards contaminated with raw chicken bacteria, including Salmonella and Listeria. On many wooden boards, bacterial numbers fell by more than 99% within 3 hours, while plastic boards often kept high counts until they were thoroughly scrubbed and disinfected. -
Park & Cliver, 1996
This follow up work showed that bacteria on wood tend to move into the surface structure and quickly lose viability. On plastic, bacteria stayed on the surface and remained recoverable for longer. This supports using a hard, dense, low porosity wood or grass like moso bamboo. -
Food Standards and EFSA guidance
European food safety guidance allows both wood and plastic for professional kitchens, as long as boards are kept in good condition and cleaned above 60°C or with food safe sanitisers. Dense wooden or bamboo boards that avoid deep knife grooves are preferred for easier cleaning. -
Bamboo specific findings
Published material testing shows that moso bamboo has a Janka hardness of around 1,380 lbf, which is harder than many common timbers. Harder, tighter grained boards resist deep knife scars, which are known to trap bacteria. Lab tests on bamboo composites have also shown reduced bacterial adhesion compared with softer woods and low quality plastics when washed with standard detergent.
So while not every paper uses the word “bamboo” in the title, the science is consistent: a dense, well finished moso bamboo board that is washed promptly and dried upright will usually harbour fewer live bacteria over time than a heavily scarred plastic board left damp on the counter.
Why moso bamboo cutting boards help reduce bacteria
Moso bamboo is a fast growing, eco friendly grass that behaves like a hardwood once it is laminated into a board. Several specific features make it well suited to reducing bacterial build up in day to day use.
1. Hard, tight structure
Moso bamboo is harder than beech and many acacias. That means:
- Fewer deep knife grooves where raw meat juices can collect
- A smoother surface that is easier to scrub clean with hot water and washing up liquid
- Less fibre tear out, so bacteria have fewer hiding places
2. Controlled moisture absorption
Unlike cheap plastic boards that can stay wet on the surface, bamboo absorbs a thin film of moisture, then dries out. Several wood hygiene studies show that when boards dry fully within 12 hours, bacterial survival drops sharply.
3. Naturally low odour retention
Users often notice that raw onion or garlic smells fade more quickly from bamboo than from soft plastic. That is a useful practical sign that residues are not clinging to the surface, which is consistent with lower long term bacterial build up when the board is washed correctly.
4. Eco friendly and food safe
Moso bamboo grows to harvest height in about 5 years and can be cut without killing the root system. That makes a bamboo board a more eco friendly choice than many tropical hardwoods. Deer & Oak boards are finished with food safe mineral oil rather than lacquers, so there is no peeling coating to trap dirt.
How to use bamboo cutting boards to keep bacteria low
The studies are clear on one thing: material alone is not enough. How you use and care for your board is just as important as what it is made from.
-
Separate raw and ready to eat foods
Use one board for raw meat and poultry, and another for bread, fruit and cooked food. The Deer & Oak Bamboo Double Pack gives you a 45x35cm board and a 38x28cm board so you can dedicate each to a different task. -
Wash within 10 minutes of use
Rinse off juices, then wash with hot water and standard washing up liquid. Scrub for at least 20 seconds. This simple routine removes the vast majority of bacteria before they dry onto the surface. -
Dry upright, not flat
Stand your board on its edge so air can circulate. Most bacterial survival studies assume the board is allowed to dry. Leaving it in a puddle on the worktop keeps it damp and slows that natural die off. -
Oil every 4 to 6 weeks
Apply a thin coat of food safe mineral oil to keep the bamboo from drying and cracking. A smooth, well sealed surface is easier to clean and less likely to hold onto residues. -
Replace if deeply scarred
If a board has many deep cuts you cannot clean easily with a brush, it is time to sand it back or replace it. This applies to plastic and wood alike.

Who this is for (and who it is not for)
Ideal for:
- Home cooks who want a more eco friendly board that supports lower bacterial survival when cleaned well
- Families preparing raw meat several times a week who need clear separation between raw and ready to eat foods
- People who sharpen knives and want a surface that is kinder to edges than glass or ceramic
- Anyone who prefers the warm feel of natural materials over plastic in a visible kitchen space
Not recommended for:
- Users who insist on putting boards through a 70°C dishwasher cycle every day, as this can warp bamboo and wood
- Commercial kitchens that are required to use colour coded plastic systems by local regulations
- People who do not want to oil a board at all, even every 4 to 6 weeks
- Anyone needing a disposable, ultra light board for camping or one off use
FAQ
Q: Are bamboo cutting boards really safer than plastic for bacteria?
A: Studies on wood versus plastic show that many wooden boards reduce recoverable bacteria by up to 99% within a few hours, while plastic can keep bacteria on the surface until it is disinfected. Moso bamboo behaves like a hard wood, so when it is washed promptly and dried upright, it can support lower bacterial survival than a heavily scarred plastic board.
Q: Can I put a moso bamboo board in the dishwasher?
A: It is not recommended to put bamboo or any wooden board in a dishwasher, as repeated high heat and steam can cause warping and cracking. Hand wash with hot water and washing up liquid for at least 20 seconds, then dry the board on its edge so air can circulate around both faces.
Q: How long will a Deer & Oak bamboo cutting board last?
A: With normal home use, washing after each session and oiling every 4 to 6 weeks, a moso bamboo board can last around 5 to 10 years. If the surface becomes heavily scarred, you can lightly sand it and re oil to extend its life before considering a replacement.
Q: Which size bamboo board should I choose for hygiene and ease of use?
A: For most kitchens a 45x35cm board gives enough space to keep raw and cooked items apart during prep, while a 38x28cm board suits smaller worktops or side tasks. Many households use a double pack so one board is reserved for raw meat and the other for bread, fruit and cooked foods.
Which Deer & Oak bamboo board should you pick?
If your priority is reducing bacteria while keeping prep practical, start with a moso bamboo board at 45x35cm. The Deer & Oak Large Bamboo Board (DNO-BCB-LG) at 1.8 kg gives you stable space for raw meat, vegetables and carving, while its density helps resist deep knife grooves. Pair it with the Medium Bamboo Board (38x28cm) or choose the ready made Bamboo Double Pack so you can clearly separate raw and ready to eat foods.
If you prefer a darker finish, the Carbonised Bamboo Board uses carbonised bamboo with similar hygiene benefits and a richer colour. For heavier carving or serving joints of meat, some cooks like to add a thicker butcher style board, such as the Deer & Oak option available on Amazon.
You can see the full range of bamboo and acacia boards on the Deer & Oak website under chopping boards or explore curated sets in the board sets collection. Choose the size that fits your worktop, keep it clean and dry, and you will be using the same science that underpins those wood versus plastic studies in your own kitchen every day.
