The safest cutting boards are made of nonporous materials like plastic or well-maintained wood, provided you separate boards by food type and replace worn surfaces.
Wondering what the safest cutting boards are made of usually comes from a real kitchen concern: raw chicken juice touching tonight’s salad. The materials themselves matter less than how you use them. Both the FDA and USDA say wood and nonporous surfaces are acceptable for raw meat and poultry. The real safety factor is keeping raw proteins away from ready-to-eat foods and knowing when a board has outlived its usefulness.
Here’s what the federal guidance actually says about materials, cleaning, and the mistakes that cause most problems.
Which Materials Are Safest for Cutting Boards?
Food-safety agencies do not crown a single “safest” material. Instead, they group boards into two broad camps: nonporous surfaces like plastic, glass, marble, and pyroceramic, and porous-but-acceptable surfaces like wood and bamboo. The FDA notes that plastic or other nonporous boards can be run through the dishwasher, which makes sanitation simpler.
The property that matters most is a hard, smooth, nonporous surface. Bacteria have fewer places to hide on a smooth board than on a deeply scored one, regardless of what it’s made from. Wood is a perfectly acceptable food-contact material in federal guidance, but the official advice emphasizes thorough washing and drying rather than claiming wood is inherently safer than plastic.
Bamboo appears in extension guidance as a common option, though no federal agency has issued a safety ranking that compares bamboo against wood or plastic directly.
How Should You Clean and Sanitize a Cutting Board?
The cleaning method matters more than the material. Michigan State University Extension, which publishes USDA-linked food-safety guidance, recommends washing boards with hot, soapy water after each use. For a deeper sanitizing step, mix 1 tablespoon of unscented liquid chlorine bleach into 1 gallon of water, let the solution sit on the board for several minutes, then rinse and air-dry or pat dry.
One caveat from the same guidance: laminated boards may crack or split over time, which creates seams where bacteria can collect. Nonporous boards like plastic handle the dishwasher fine, but boards that develop deep grooves or warping need replacing.
What Mistakes Make a Cutting Board Unsafe?
Two errors cause most cutting-board problems. The first is using one board for everything. The FDA recommends keeping one board for produce and another for raw meat, poultry, and seafood. If you only have one board, the FDA says to prepare fruits and vegetables first, then handle raw proteins — never the reverse.
The second mistake is keeping a board with deep knife scars. Over time, cutting creates grooves that harbor bacteria even after washing. Once a board shows deep scoring, it’s time to retire it. This applies to wood and plastic alike.
The table below summarizes how each common material stacks up for home use.
| Material | Safety Profile | Best Practice |
|---|---|---|
| Plastic | Nonporous; dishwasher-safe | Replace when grooves appear |
| Wood | Acceptable per USDA; sanitize regularly | Air-dry fully after washing |
| Bamboo | Common option; no federal ranking | Treat like wood; watch for cracks |
| Glass | Nonporous; easy to sanitize | Can dull knives quickly |
| Marble / Pyroceramic | Nonporous; smooth surface | Heavy; can dull knives |
| Laminated | May crack or split | Watch seams; replace if damaged |
Does the Material Matter for Raw Meat?
For raw meat and poultry, the USDA says consumers may use wood or a nonporous surface like plastic. The key is consistent sanitation, not the material’s origin. The FDA’s guidance for produce preparation reinforces the same point: use one board for produce and another for raw proteins to avoid cross-contamination.
After handling raw meat, wash the board with hot soapy water, then apply the bleach sanitizing solution described above. Let it sit, rinse, and dry. This routine works for both wood and plastic surfaces.
The Michigan State guidance on cutting boards and food safety lays out these steps in detail for home kitchens.

Can You Put Any Board in the Dishwasher?
No. The FDA specifically says plastic and other nonporous boards can go in the dishwasher, but wood boards should be hand-washed. High heat and prolonged moisture can warp or crack wood, creating new hiding spots for bacteria. Laminated boards also carry a cracking risk, so hand-washing is the safer choice for those too.
The practical rule: nonporous boards get the dishwasher, wood and laminated boards get the sink. Either way, the bleach sanitizing step keeps surfaces safe.
FAQs
How often should you replace a cutting board?
Replace any board once it develops deep grooves, cracks, or warping that won’t wash clean. Boards with heavy scoring — generally after a few years of daily use — can harbor bacteria even after sanitizing. When in doubt, run your fingernail across the surface; if it catches in a groove, the board needs retirement.
Is a wood or plastic cutting board safer for raw chicken?
Both are acceptable under USDA guidance, so the deciding factor is your cleaning routine. Plastic is dishwasher-safe, which makes sanitation convenient. Wood requires hand-washing plus a bleach sanitizing solution. Either works if you clean thoroughly after handling raw chicken and keep that board separate from produce.
What’s the right way to sanitize after cutting raw meat?
Wash the board in hot, soapy water first. Then mix 1 tablespoon of unscented liquid chlorine bleach into 1 gallon of water and let the solution sit on the board for several minutes. Rinse well, then air-dry or pat dry. This method applies to both wood and nonporous surfaces.
