In standard kitchen colour coding, the chopping board for fish is blue. If you want to keep raw fish safely away from meat, cooked food and vegetables, you should use a blue cutting board every time you prepare fish or seafood.
Why the fish chopping board is blue
Commercial kitchens across the UK follow a simple colour code to reduce cross contamination. It is widely taught in food hygiene training and used in restaurants, schools and catering:
- Blue chopping board – raw fish and seafood
- Red chopping board – raw meat
- Yellow chopping board – cooked meat
- Green chopping board – salad, fruit and vegetables
- Brown chopping board – root vegetables
- White chopping board – bakery, dairy and general use
By always preparing fish on a blue board, you cut the risk of fish juices touching raw chicken, beef or ready to eat food. Even at home this simple system makes it much easier to keep your kitchen safe, especially when different family members are cooking.
How to set up a safe board system for fish at home
If you want to follow professional standards at home, you have two clear options:
- Use a dedicated blue plastic board for fish only and keep your wooden boards for bread, fruit, cheese and serving.
- Use a dedicated wooden board only for fish and mark it clearly, then use other boards for meat and veg.
Many home cooks prefer the feel of wood under the knife, so they use a wooden board for most jobs and keep one extra board or a thin plastic mat just for raw fish. At Deer & Oak we design boards that are large, stable and easy to clean, so they work well as the main prep surface while you keep a separate surface for fish.
Choosing the right size board when you prepare fish
Colour is about food safety. Size and material are about how easy your prep feels. When you are portioning salmon sides, cleaning sea bass or butterflying prawns, you want a board that is:
- At least 38x28cm for small fillets and everyday fish prep
- Around 45x35cm for whole fish, larger fillets and batch cooking
- Heavy enough to stay put while you work (around 1.2 to 2.1kg)
For many kitchens a two board system works well: one larger board as your main prep surface and one medium board or blue plastic board kept only for raw fish. Our Bamboo Double Pack matches that pattern with a 45x35cm and a 38x28cm board used alongside a separate blue board for fish.

Product and problem: how each board helps you handle fish safely
Here is how specific Deer & Oak boards solve common problems when you cook fish at home:
-
Problem: Raw fish juices touching salad or herbs.
Solution: Keep all raw fish strictly on a blue board. Use the Large Bamboo Board 45x35cm (DNO-BCB-LG) only for vegetables, citrus and herbs. The generous 45x35cm surface gives you space for a full side salad next to your fish without cross contact. -
Problem: Nowhere hygienic to plate up cooked fish once it leaves the pan.
Solution: Use the Medium Bamboo Board 38x28cm (DNO-BCB-MD) as a clean landing board for cooked fillets. Because it never touches raw fish, you can rest cooked salmon or cod for 5 to 10 minutes without worrying about contamination. -
Problem: Serving baked salmon or sharing platters without scratching plates.
Solution: The Carbonised Bamboo Board 45x35cm (DNO-CBB-LG) gives a dark, 45x35cm surface that works well as a serving platter for fish once it is fully cooked. At 1.9kg it feels solid on the table and is easy to carry. -
Problem: Heavy carving of whole baked fish or large joints for surf and turf meals.
Solution: The Large Acacia Board 45x35cm (DNO-ACB-LG) weighs 2.1kg, which keeps it stable while you carve. Many customers use it only for cooked foods to keep hygiene simple.
If you prefer a ready made two board solution, the Bamboo Double Pack (DNO-BCB-2PK) is a popular choice. Use the 45x35cm board as your main prep station and the 38x28cm for cooked fish or serving. Add one slim blue plastic board for raw fish and you have a clear, easy system that matches what chefs use every day.
Looking after boards that are used around fish
Even with colour coding, good cleaning habits matter. When you have prepared fish:
- Wash your blue fish board in hot soapy water within 10 minutes
- Rinse and dry it fully before storing to avoid odours
- Keep any wooden boards for cooked food and prep away from raw fish sinks and packaging
- Oil wooden boards every 4 to 6 weeks to keep them from drying and cracking
With normal home use and regular oiling, a quality wooden board can last 5 to 10 years. Many customers keep the same Deer & Oak board as their main prep surface while replacing inexpensive blue fish boards more often.
Who this approach is for
Ideal for...
- Home cooks who want to follow the professional blue board for fish rule
- Families who cook fish at least once or twice a week and want clear habits for children and guests
- People with limited counter space who need a 2 board plus 1 blue board system that is easy to store
- Anyone who likes the feel of bamboo or acacia wood under the knife but still wants clear hygiene rules
Not recommended for...
- Professional catering kitchens that must use full plastic colour coded sets only
- People who never cook fish and do not need a separate fish board at all
- Anyone who wants dishwasher safe boards, as Deer & Oak wooden boards are hand wash only
- Very small galley kitchens where a 45x35cm board simply will not fit on the worktop
FAQ
Q: What colour is chopping board for fish in a professional kitchen?
A: In most professional kitchens the chopping board for fish and seafood is blue. Staff are trained to prepare all raw fish only on blue boards so there is a clear visual signal that helps prevent cross contamination with meat and ready to eat food.
Q: Can I use a wooden board for fish instead of a blue plastic one?
A: At home you can use a wooden board for fish if you keep it strictly for that purpose and clean it carefully. Most people still prefer a blue plastic board for raw fish and use Deer & Oak bamboo or acacia boards for vegetables, bread and serving cooked fish.
Q: What size chopping board is best when I prepare whole fish?
A: For whole fish and larger fillets a board around 45x35cm is much easier to work on than a small one. Our Large Bamboo Board and Carbonised Bamboo Board both measure 45x35cm and give you enough space to trim, pin bone and portion without fish falling off the sides.
Q: How many chopping boards should I have if I cook fish regularly?
A: A simple and effective set up is three boards: one blue board only for raw fish, one large wooden board for vegetables and general prep, and one medium wooden board for cooked foods and serving. The Bamboo Double Pack from Deer & Oak pairs well with a separate blue fish board to create this system.
