Wooden utensils have long been trusted companions in professional and domestic kitchens alike. Appreciated for their warmth, tactile quality and timeless design, they raise an essential question: are wood utensils safe for food contact?
The conversation around wood in the kitchen is often shaped by assumptions: some see it as a porous material that is easily contaminated, while others consider it to be inherently hygienic due to its natural antibacterial properties. In truth, the safety of wooden utensils depends on various factors, such as the type of wood, how it is treated and how it is used and maintained.
This guide will reveal what the science and regulations really say about wood and hygiene, how bacteria interact with wooden surfaces compared to plastic, and what brands need to know when designing or sourcing food-safe wooden components.
Wood behaves differently from synthetic materials when it comes to kitchen tools, especially in terms of how it interacts with moisture, food residues and bacteria. While some manufacturers may be concerned about its porous nature, scientific studies suggest that wood can offer surprising advantages when properly selected and treated.
Safety depends on three main factors:
One of the most cited studies on this topic examined how bacteria behave on wooden and plastic cutting surfaces. Dean O. Cliver and Nese O. Ak of the University of California, Davis, found that bacteria were more likely to survive on plastic than wood. Their findings challenge common assumptions: “On wooden surfaces, bacteria were often absorbed and subsequently died within minutes, while on plastic surfaces, they remained on the surface and often multiplied overnight”
These observations apply not only to chopping boards, but also to wooden utensils, especially those made from the same species of wood and treated with similar finishes.
One of the most debated aspects of wooden kitchen tools is porosity. At first glance, a porous material may appear less hygienic than a smooth, non-porous one. However, scientific research shows that the way wood interacts with bacteria is more complex (and often more favourable) than is commonly assumed.
Wood is made of microscopic capillaries that once transported water within the tree. When bacteria-laden moisture lands on the surface of a wooden utensil, these capillaries can draw the liquid inwards. This reduces the amount of free moisture left on the surface, which bacteria need to survive and multiply.
Once absorbed, microorganisms become trapped within the wood's structure, where they are deprived of nutrients and moisture. This leads to their gradual inactivation.
Controlled studies comparing wooden and plastic food-contact surfaces have demonstrated significant differences in bacterial survival.
A widely cited study published in the Journal of Food Protection observed that bacterial counts on hardwood surfaces dropped by 98–99.9% within hours under controlled conditions, with significant reductions evident within minutes of contamination. By contrast, plastic surfaces allowed bacteria to remain accessible and viable for longer.

When it comes to materials that come into contact with food, safety is strictly regulated. Both the European Union and the United States recognise wood as a suitable material for utensils, provided that it meets specific safety and hygiene criteria.
Under this regulation, any material that comes into contact with food must not:
This framework does not exclude wood. In fact, the regulation permits its use, provided it is properly treated and maintained in hygienic conditions. This includes ensuring that the wood can be cleaned, is non-toxic, and is suitable for repeated contact with food.
The European Food Safety Authority (EFSA) supports the use of wooden materials in food preparation, particularly if they are made from suitable hardwood species and finished with food-safe coatings. Countries such as Germany and France also provide national guidelines that permit the use of wooden tools in professional kitchens under regulated conditions.
In the United States, the Food and Drug Administration (FDA) acknowledges wood as a permissible food-contact material in certain applications. While the Food Code advises against the use of wood in some contexts involving high moisture levels (e.g. meat-cutting boards in commercial kitchens), it explicitly permits the use of hard maple and other close-grained hardwoods for utensils and chopping boards.
At Minelli, we have decades of experience in creating wooden components that are both beautiful and fully compliant with international food contact regulations. Every element, from kitchen tools to utensil handles, is engineered with safety, precision and design integrity in mind.
