If you want to know how bamboo cutting boards compare to plastic for bacteria, controlled kitchen studies show that hard bamboo can hold up to 2 to 3 times fewer live bacteria on the surface after washing than heavily scored plastic boards. In everyday terms, a well cared for moso bamboo board is usually the safer long term option for bacteria than a scratched plastic board, as long as you clean and dry it properly.
How bamboo cutting boards behave with bacteria
Bamboo is a grass with a naturally dense structure. Moso bamboo in particular has a Janka hardness of around 1,380 lbf, which is significantly harder than many plastic boards. That hardness matters for bacteria because it means:
- Fewer deep knife grooves where bacteria can hide
- Less moisture absorption when the board is properly oiled
- Faster surface drying, which bacteria dislike
Several food hygiene tests have found that when both boards are scrubbed and dried in the same way, plastic starts off similar to bamboo. The difference appears after a few months of use. Plastic boards collect knife scars that are hard to clean. In those scars, bacterial counts can remain 10 to 100 times higher than on smoother bamboo or wooden boards.
Our Deer & Oak moso bamboo boards are pre oiled to slow moisture absorption and help the surface dry evenly. A dry surface is one of the simplest ways to make your board less friendly to bacteria.
How plastic cutting boards behave with bacteria
Brand new plastic boards are non porous and easy to disinfect. On day one, they can be very hygienic. The issue is what happens after 6 to 12 months of regular chopping.
- Knives leave visible grooves that you can feel with your fingers
- Those grooves trap raw meat juices and food particles
- Even with washing, bacteria can remain alive deep inside the cuts
In lab tests, heavily scored plastic boards often retain viable bacteria even after thorough washing, while smoother bamboo or wood boards show far fewer survivors. This does not mean plastic is unsafe, but it does mean you may need to replace plastic boards more often to keep bacterial levels low.
Moso bamboo vs plastic: eco friendly and hygiene together
There is a second question many people ask alongside bacteria: is bamboo more eco friendly than plastic? With moso bamboo, the answer is usually yes.
- Moso bamboo can grow up to 90 cm in a single day and reaches harvest size in about 5 years
- It is a renewable grass, not a slow growing hardwood
- It avoids the long term waste issues of plastic chopping boards
Our Deer & Oak moso bamboo range, including the Large Bamboo Board (45x35 cm, 1.8 kg), uses responsibly sourced bamboo. When cared for, a bamboo board can last 5 to 10 years, which means fewer replacements than thin plastic mats that may need changing every 6 to 18 months.
Simple hygiene habits that matter more than material
Material choice is important, but daily habits decide how many bacteria stay on your board. Whether you use bamboo or plastic, follow these steps:
-
Hot water and washing up liquid after every use
Scrub both sides for at least 20 to 30 seconds. For raw meat, wash immediately, not later. -
Stand the board to dry
Drying upright allows air to circulate. Aim for the board to be fully dry within 2 hours. Bacteria thrive on damp surfaces. -
Use separate boards
Have one board for raw meat and fish and another for bread, fruit and ready to eat foods. Our Bamboo Double Pack is designed exactly for this, with a 45x35 cm and a 38x28 cm board. -
Disinfect occasionally
For bamboo, use a mild solution of white vinegar and water or a food safe sanitiser. For plastic, you can sometimes use diluted bleach, but always follow the manufacturer’s instructions. -
Oil bamboo boards every 4 to 6 weeks
Use food grade mineral oil. A well oiled board absorbs less moisture and dries faster, which helps keep bacterial numbers down.

Product and problem: matching boards to how you cook
To choose between bamboo and plastic, start with the main problem you want to solve.
Problem: worried about bacteria from raw meat
If you mostly worry about raw chicken and mince, you need a surface that resists deep cuts and dries quickly. A Large Bamboo Board (45x35 cm) or Carbonised Bamboo Board (45x35 cm) gives you enough space to keep raw meat separate from other ingredients.
- Why bamboo helps: fewer deep grooves, easier to scrub clean, dries within a few hours
- How to use: keep one bamboo board only for raw meat and fish, another for veg and bread
Problem: limited space but still want eco friendly hygiene
For smaller kitchens, the Medium Bamboo Board (38x28 cm, 1.2 kg) provides a compact surface that still benefits from the hardness of moso bamboo. It is easier to lift and wash in a small sink than a large plastic board of similar area.
Problem: serving and food safety in one board
If you like to prepare and serve on the same board, both carbonised bamboo and acacia give you a smart look with solid hygiene. The Deer & Oak chopping board range includes boards that work for both daily prep and weekend platters.

- People who often leave boards soaking in water or sitting wet in the sink
- Those who never want to oil or maintain a board and prefer to replace cheap plastic frequently
FAQ
Q: Are bamboo cutting boards really safer than plastic for bacteria?
A: When both are new and cleaned well, they perform similarly. Over time, plastic often develops deep grooves that can hold 10 to 100 times more bacteria than the smoother surface of a well maintained bamboo board. With good cleaning and drying habits, moso bamboo usually offers better long term hygiene than a heavily scarred plastic board.
Q: How often should I replace a bamboo cutting board for hygiene?
A: With regular cleaning and oiling every 4 to 6 weeks, a quality moso bamboo board can last 5 to 10 years. Replace it if you see deep cracks, warping or stains that do not scrub out, as those areas can shelter bacteria.
Q: Can I put a bamboo cutting board in the dishwasher?
A: No, bamboo should not go in the dishwasher. High heat and long soaking can cause swelling, cracking and warping, which then create spaces where bacteria can hide. Hand wash in hot soapy water and dry upright instead.
Q: Should I have separate bamboo boards for meat and vegetables?
A: Yes, it is wise to use at least two boards, one for raw meat and fish and one for bread, fruit and vegetables. Our Bamboo Double Pack combines a 45x35 cm and a 38x28 cm board so you can clearly separate raw and ready to eat foods and keep cross contamination to a minimum.
Which Deer & Oak board should you choose?
If your main concern is bacteria and you want an eco friendly upgrade from plastic, the Large Bamboo Board (DNO-BCB-LG, 45x35 cm, 1.8 kg, moso bamboo) is the most practical starting point. Pair it with the Medium Bamboo Board (DNO-BCB-MD, 38x28 cm, 1.2 kg) or choose the Bamboo Double Pack to keep raw and ready to eat foods completely separate.
If you prefer a darker finish with the same hygienic benefits, the Carbonised Bamboo Board offers a 45x35 cm surface with a subtle caramel colour. For those who also want the option of a heavier serving board, our bestselling chopping boards include acacia and butcher’s block styles that balance food safety with presentation.
Whichever size you choose, pairing moso bamboo with sensible cleaning habits gives you a clear, practical step up from tired plastic boards when it comes to everyday kitchen bacteria.
