Cooking over an open flame is a timeless tradition that evokes memories of camping trips, backyard barbecues, and warm summer nights. However, when it comes to cooking over treated wood, many of us are left wondering if it’s safe to do so. In this article, we’ll delve into the world of treated wood, explore the risks associated with cooking over it, and provide you with the information you need to make informed decisions about your outdoor cooking habits.
What is Treated Wood?
Treated wood is wood that has been infused with chemicals to resist rot, decay, and insect damage. The most common type of treated wood is pressure-treated wood, which is made by forcing chemicals into the wood under pressure. The chemicals used to treat wood can vary, but some of the most common include:
- Arsenic
- Chromium
- Copper
- Borate
These chemicals can help extend the life of the wood, making it a popular choice for outdoor construction projects such as decks, fences, and playgrounds.
The Risks of Cooking Over Treated Wood
While treated wood may be great for building outdoor structures, it’s not necessarily the best choice for cooking. When you cook over treated wood, there’s a risk of releasing toxic chemicals into the air and onto your food. These chemicals can come from the wood itself, as well as from the combustion process.
- Arsenic: Arsenic is a known carcinogen that can be released into the air when treated wood is burned. Exposure to arsenic has been linked to a range of health problems, including cancer, neurological damage, and reproductive issues.
- Chromium: Chromium is another chemical commonly used to treat wood. When burned, chromium can release toxic fumes that can cause respiratory problems and other health issues.
- Copper: Copper is generally considered to be a safer alternative to other chemicals used to treat wood. However, it can still release toxic fumes when burned, particularly if the wood is not properly seasoned.
The Science Behind Cooking Over Treated Wood
When you cook over treated wood, the heat from the fire can cause the chemicals in the wood to vaporize and release into the air. This process is known as volatilization. The chemicals can then be carried onto your food through the smoke and flames.
In addition to the chemicals in the wood, the combustion process itself can also release toxic compounds into the air. These compounds can include:
- Polycyclic aromatic hydrocarbons (PAHs): PAHs are a type of carcinogen that can be released into the air when wood is burned. They can bind to food and cause a range of health problems.
- Volatile organic compounds (VOCs): VOCs are a type of chemical that can be released into the air when wood is burned. They can cause a range of health problems, including respiratory issues and neurological damage.
Is Cooking Over Treated Wood Safe?
While the risks associated with cooking over treated wood are real, it’s worth noting that the science is not yet conclusive. Some studies have suggested that the risks of cooking over treated wood are relatively low, particularly if the wood is properly seasoned and the fire is well-ventilated.
However, other studies have suggested that the risks are more significant, particularly for people who cook over treated wood regularly. The bottom line is that cooking over treated wood is not without risk, and it’s up to each individual to decide whether the benefits outweigh the potential drawbacks.
Alternatives to Cooking Over Treated Wood
If you’re concerned about the risks of cooking over treated wood, there are several alternatives you can consider:

- Gas grills: Gas grills are a convenient and safe alternative to cooking over wood. They don’t release the same chemicals into the air, and they’re often easier to clean and maintain.
Best Practices for Cooking Over Treated Wood
If you do decide to cook over treated wood, there are several best practices you can follow to minimize the risks:
- Choose the right wood: Look for wood that has been treated with safer chemicals, such as copper. Avoid wood that has been treated with arsenic or chromium.
- Season the wood: Seasoning the wood can help reduce the amount of chemicals released into the air. Look for wood that has been properly seasoned and dried.
- Use proper ventilation: Proper ventilation can help reduce the amount of chemicals released into the air. Make sure your cooking area is well-ventilated, and consider using a fan to blow the smoke away from your food.
- Keep the fire small: Keeping the fire small can help reduce the amount of chemicals released into the air. Avoid building large fires, and keep the flames low and controlled.
Conclusion
Cooking over treated wood is a complex issue that requires careful consideration. While the risks are real, they can be minimized by following best practices and choosing safer alternatives.
