Wooden cutting boards have been part of kitchens for centuries. Their durability, natural appearance and pleasant tactile qualities have made them a trusted choice for both home cooks and professional chefs.
At the same time, questions about hygiene and food safety continue to surface whenever wood is discussed as a food-contact material. How safe are wooden cutting boards? Can bacteria survive on its surface? What do scientific studies and food-contact regulations actually say?
The answers are often more interesting than many people expect.
When properly designed, manufactured and maintained, wooden cutting boards offer a combination of performance, longevity and food-contact suitability that continues to make them one of the most widely used kitchen surfaces worldwide.
In this guide, you'll discover what research reveals about wooden cutting board safety, how different wood species influence performance and what brands should consider when developing products intended for food-contact applications.
Are wooden cutting boards really less hygienic?
Many people assume that wooden cutting boards are less hygienic because wood is a porous material. The logic seems simple: if a surface absorbs moisture, it should also retain bacteria more easily.
Yet scientific research has repeatedly challenged this assumption.
Over the past several decades, studies investigating the behaviour of foodborne bacteria on cutting boards have found that certain hardwoods can create surprisingly unfavourable conditions for microbial survival. In controlled laboratory tests, researchers observed bacterial reductions on wooden surfaces that contradicted the long-held belief that wood represents a higher hygiene risk.
This does not mean that every wooden cutting board is automatically safe, nor that maintenance becomes less important. Material selection, manufacturing quality and proper care remain essential factors.
What the evidence does suggest is that the traditional perception of wood as the less hygienic option deserves a closer look.
What science says about wooden cutting boards
The perception that wooden cutting boards are inherently unhygienic is not fully supported by scientific literature.
A 2020 review examined decades of research on the antimicrobial properties of wood and the methods used to evaluate its hygienic safety. The authors noted that concerns about wood often stem from its porous and hygroscopic nature, which has led many people to question its suitability for food-contact applications. However, the review also highlights that several studies have demonstrated antimicrobial activity in commonly used wood species.
According to the authors, wood has traditionally been used for food preparation, cutting, fermentation and packaging and a growing body of research supports its use as a safe material for food-contact surfaces under appropriate conditions. The review specifically states that some commonly used wood species exhibit antimicrobial properties and can be considered suitable for hygienically important environments, including food-contact applications.
The paper also emphasizes that the behaviour of microorganisms on wood is influenced by multiple factors, including the wood species, the characteristics of the material, environmental conditions such as humidity and temperature and the type of microorganism involved. As a result, hygiene performance cannot be evaluated based solely on the fact that wood is porous.
Rather than viewing wood as a passive material, researchers increasingly examine the interaction between wood surfaces and microorganisms, investigating how specific wood characteristics may contribute to microbial survival or reduction.

Does the type of wood make a difference?
Not all wooden cutting boards behave in the same way.
The safety, durability and overall performance of a cutting board are influenced by the characteristics of the wood species used to manufacture it. Density, grain structure, moisture movement and natural extractives can all affect how a board performs throughout its lifecycle.
For this reason, hardwoods are generally preferred for food-contact applications. Species such as maple, olive, walnut and beech are widely used in kitchenware because they combine durability with good dimensional stability and an attractive appearance.
Research reviewed in the scientific literature suggests that antimicrobial behaviour can also vary between wood species. According to Munir et al. (2020), factors such as the type of wood, the part of the tree and the environmental conditions may influence the antimicrobial properties observed during testing.
The review also highlights that wood extractives (naturally occurring compounds found in certain species of wood) have been associated with antimicrobial activity in various studies. Consequently, researchers are increasingly evaluating individual wood species rather than treating all wood materials as a single category.
What the regulations say about wooden cutting boards
The safety of a wooden chopping board is not determined solely by the material it is made from. Rather, regulatory frameworks focus on the final product's suitability for food-contact applications.
In Europe, wooden chopping boards are subject to the general requirements of Regulation (EC) No. 1935/2004 governing food-contact materials. The Council of Europe provides additional guidance for food-contact materials through Resolution CM/Res(2020)9, which complements the European regulatory framework and supports the safe use of materials intended to come into contact with food.
We can therefore conclude that food safety depends on the entire development process, including material selection, manufacturing practices, surface treatments and quality control.
Consequently, when evaluating a wooden chopping board, it is necessary to consider not only the material itself, but also how the product has been designed, produced and intended to be used.
Why choose wood for a cutting board?
Choosing wood for a cutting board is rarely a matter of aesthetics alone.
The material offers a combination of characteristics that directly influence how a product performs throughout its lifecycle. Strength, dimensional stability, repairability and tactile comfort all contribute to the experience of daily use.
Unlike many materials, wood evolves rather than simply wears out. Minor surface marks can often be maintained, refinished or incorporated into the natural ageing process of the product. This allows a cutting board to retain its functionality and character over time rather than being treated as a disposable item.
Wood also offers exceptional versatility from a design and manufacturing perspective. Different species provide different visual identities, grain structures and performance characteristics, allowing products to be tailored to specific positioning strategies, from professional kitchen tools to premium serving collections.
Perhaps most importantly, wood creates an immediate connection between the user and the product. Its warmth, texture and visual depth transform a cutting board from a simple kitchen accessory into an object people enjoy using every day.
This combination of performance, longevity and material experience helps explain why wood continues to be one of the most trusted choices for cutting boards across both professional and domestic environments.
The Minelli Group approach to wooden cutting boards
A cutting board may appear to be a simple product. In reality, however, its performance depends on a series of decisions made long before it reaches the kitchen.
The wood species selected, the grain orientation, the dimensional stability, the manufacturing precision and the food-contact finishes all contribute to the final result. When all these elements are considered together, the cutting board becomes a product designed to perform consistently over time.
At Minelli Group, product development starts from this holistic perspective. By combining material expertise, industrial manufacturing capabilities and co-design support, we transform ideas into wooden components and finished products that are tailored to the needs of modern kitchenware brands.
