Is It Safe to Cook Over a Fire Made from Treated Wood?

Chemical Contamination and Health Risks

When treated wood is burned, it releases volatile organic compounds (VOCs) into the air. These chemicals can then be absorbed by food when it’s cooked over the fire. Some common chemicals released from treated wood include pentachlorophenol (PCP), dioxins, and furans, all of which are known carcinogens. Cooking without a pot or lid can increase the risk of contamination, as oils and moisture from the food can interact with the toxic chemicals in the air and transfer them to the food.

Cooking Techniques for Safer Meals

If you’re in a situation where you need to cook over a fire made from treated wood, use a metal or cast-iron pot with a tight-fitting lid to minimize the risk of contamination. The lid will help to prevent VOCs from entering the pot, and metal or cast-iron can help to contain any chemicals that do penetrate. Additionally, always cook with a windbreak to reduce the amount of toxic chemicals released into the air.

Alternative Fuel Sources

If possible, it’s always best to find alternative fuel sources for your fire, such as dead branches or other natural materials. When using natural materials, make sure to choose dry, well-seasoned wood to minimize smoke and emissions. If you’re in a survival situation, look for branches that are at least 1 inch in diameter and 3-4 feet long for optimal burning efficiency. Avoid burning green or damp wood, as this can produce more smoke and toxic fumes.
