Should You Not Cook With Railroad Tie Wood
Burning or cooking with railroad tie wood exposes you to creosote and heavy metal residues that were never meant to meet food. So should you not cook with railroad tie wood? The short answer is no, you should not. These ties are treated industrial wood, not firewood, and the risks are real.
This guide explains what is inside railroad ties, what happens when you burn them, and safer wood choices for your grill or smoker.
What Railroad Ties Are Actually Made Of
Railroad ties are built to survive decades of rain, sun, and heavy trains. That job requires chemical treatment, not just plain wood.
Most ties fall into two groups:
- Creosote-treated ties. Creosote is a dark, oily preservative made from coal tar. It soaks deep into the wood to stop rot and insects.
- Chromated copper arsenate (CCA) ties. This treatment uses copper, chromium, and arsenic to protect the wood.
Both types are toxic by design. They are made to kill fungi, termites, and other pests. That same chemistry does not care whether the target is a bug or your dinner.
Creosote: The Main Concern
Creosote is a mix of hundreds of chemicals, including polycyclic aromatic hydrocarbons (PAHs). Many PAHs are known or suspected carcinogens.
When creosote burns, it does not simply disappear. It releases smoke and particles that carry those compounds into the air, onto your skin, and onto any food nearby.
Heavy Metals And Arsenic
Older CCA ties can contain arsenic, chromium, and copper. Burning does not destroy these metals. It concentrates them in the ash and sends some into the smoke.
That ash then lands on your grill grates, your food, and the ground around your fire pit. Metals do not break down. They build up.
Should You Not Cook With Railroad Tie Wood
No. Cooking with railroad tie wood is a bad idea for several clear reasons.
1. Toxic Smoke Coats Your Food
Grilling and smoking work by moving smoke over food. That is the whole point. But when the smoke comes from creosote-soaked wood, your food absorbs those chemicals along with the flavor.
You cannot rinse them off. The compounds settle into the surface and, in fatty foods, into the meat itself.
2. Ash Contaminates Everything It Touches
Railroad tie ash can hold heavy metals and arsenic. If you dump that ash in your garden or yard, it stays in the soil for years.
It can also cling to grill grates. The next time you cook, that residue can transfer to whatever you put on the grill.
3. Skin And Eye Irritation
Creosote is a known irritant. Handling treated ties or breathing the smoke can cause skin rashes, eye burning, and throat irritation.
Some people are more sensitive than others, but no one should be standing over a railroad tie fire breathing it in on purpose.
4. Long-Term Health Risks
Repeated exposure to creosote and PAHs is linked to skin, lung, and other cancers in occupational studies. Home cooks are not exposed the same way as railroad workers, but the risk is still avoidable.
Why take on any added risk when safe firewood is cheap and easy to find?
5. It Ruins The Taste Anyway
Even setting health aside, railroad ties make poor cooking wood. Creosote creates a harsh, bitter, chemical taste that no rub or sauce can hide.
You are spending money on meat only to flavor it like a tar pit. That is a waste.
What Happens When You Burn Treated Wood
Burning treated wood releases more than heat. It sends out:
- Toxic smoke and fine particles
- PAHs and other creosote compounds
- Heavy metals like arsenic, chromium, and copper
- Contaminated ash that lingers in soil
These pollutants do not just affect you. They drift into your neighbor’s yard and into the air your family breathes.
Safer Wood Options For Cooking
You have plenty of safe choices. Stick to untreated, seasoned hardwoods.
- Oak. A classic for grilling and smoking with a steady, mild flavor.
- Hickory. Strong and smoky, great for pork and beef.
- Apple and Cherry. Mild and slightly sweet, ideal for poultry and fish.
- Maple. A gentle, slightly sweet smoke that works with almost anything.
- Pecan. Similar to hickory but a bit milder.
Buy wood labeled for cooking or firewood use. Ask the seller if it was treated. If they cannot answer, walk away.
How To Spot Treated Wood
Before you burn any scrap wood, check for these signs:
- An oily or greasy feel on the surface
- A strong chemical or tar smell
- Dark, greenish, or unnatural color
- Stamps or markings like “creosote” or “CCA”
If it looks or smells like a railroad tie, do not burn it. Do not cook with it. Do not even store it near your grill.
What To Do With Old Railroad Ties
If you already have ties on your property, you do not have to panic. Just do not burn them.
- Use them for landscaping walls or garden borders if local rules allow.
- Check with your city or county about proper disposal.
- Never burn them in a fire pit, stove, or grill.
- Wash your hands after handling them.
Bottom Line
Railroad tie wood is treated with creosote or heavy metals to survive the outdoors. Those same chemicals make it unsafe for cooking.
Burning it releases toxic smoke, contaminates food, and leaves polluted ash behind. Safer, tastier options like oak, hickory, and apple wood are easy to find and cost very little.
So should you not cook with railroad tie wood? You should not. Choose clean, untreated firewood instead and keep your meals safe.
