Are wooden cutting boards safe?

Wood, plastic, bamboo: what science says

Cutting board safety is a common concern in the kitchen. Wood, plastic, bamboo—each material has its advantages, but wooden cutting boards remain among the safest options when properly maintained.

Wood vs. plastic — what really happens

Contrary to popular belief, plastic cutting boards are not more hygienic. Over time, knives create deep micro-grooves where bacteria can accumulate and resist cleaning. These cuts also release microplastics that can end up in food.

Wood, on the other hand, has natural properties: bacteria tend to be absorbed into the wood fibers, where they survive for a much shorter time than on the surface of plastic.

The case of bamboo: popular, but imperfect

Bamboo is often seen as an eco-friendly alternative, but it is very hard on knives and made of thin strips bonded with industrial glue. The result: blades dull more quickly, and long-term durability is reduced.

Which woods are best for a cutting board?

For a safe cutting board, choose tight-grain hardwoods such as:

• Maple 🍁

• Black walnut 🪵

• Cherry 🍒

These species are durable, stable, gentle on knives, and widely recognized as food-safe.

Care and hydration: the key to a safe board

A wooden cutting board should be washed by hand, dried thoroughly, and hydrated regularly. Food-grade mineral oil is a good option, but a wood butter containing beeswax is even more effective (such as Humble Artisan wood butter).The oil penetrates and nourishes the wood deeply, while the wax creates a light protective barrier against moisture. This keeps the board more stable, longer-lasting, and safer to use.

A simple solution for extra caution

To further reduce the risk of cross-contamination:Use one board for raw meats that will be cooked (chicken, seafood, etc.) and another for foods eaten raw or lightly cooked (vegetables, fruits, bread, cheese). Ask Alex from Humble Artisan about low-cost options for side cutting boards by sending him a message.

In summary

When properly chosen and well maintained, wooden cutting boards are safe, durable, and healthy. They’re kind to knives, avoid issues related to microplastics, and offer a natural, reliable solution for everyday cooking.
