Meat Belongs in the Trash, Not Your Compost

No, you should not put meat in a home compost bin. Meat, fish, bones, and other animal proteins break down very slowly in a standard backyard compost pile and create serious problems before they decompose. They attract rats, raccoons, and other animals that will tear into your bin looking for food. They also produce strong odors that your neighbors will notice, and they can introduce harmful bacteria like E. coli and salmonella into your finished compost.

The core issue is temperature. A home compost pile typically reaches 130 to 150 degrees Fahrenheit at its hottest point—warm enough to break down plant material, but not hot enough to safely kill the pathogens that live on raw meat. Commercial composting facilities reach 160 degrees or higher and are actively managed to maintain those temperatures. Your backyard pile cannot do that.

Key Takeaways

  • Meat, fish, bones, and animal fats decompose too slowly in home compost and attract rodents and other wildlife to your bin.
  • Home compost piles do not reach the temperature needed to kill harmful bacteria found on raw meat and animal products.
  • Meat scraps create strong odors that persist for weeks and can cause complaints from neighbors.
  • If you have access to a commercial composting program in your area, those facilities can safely process meat and bones.

Why Meat Attracts Animals to Your Compost

Meat is a protein-rich food source that smells like food to wildlife. Rats can detect the scent of meat from up to 150 feet away, and raccoons will remember your bin as a reliable food source after one successful raid. Once they find meat in your compost, they will return repeatedly, often damaging the bin itself in the process.

Even if your bin has a lid, determined animals can pry it open or chew through plastic. Burying meat deeper in the pile does not solve the problem—rodents will dig down to find it. The only reliable way to prevent this is to not put meat in the bin at all.

The Bacteria Problem: Why Temperature Matters

Raw meat carries bacteria like Salmonella, E. coli, and Listeria. These pathogens die when exposed to sustained heat above 160 degrees Fahrenheit. A home compost pile rarely reaches that temperature throughout, and even when the center gets hot, the outer edges stay cool. Meat in the cool zones will not be sterilized.

If you use compost containing live pathogens on vegetables or herbs you plan to eat raw, you risk foodborne illness. Even if you only use it on ornamental plants, you are spreading harmful bacteria into your soil and potentially onto your hands when you garden.

The Smell Problem

Meat produces a distinctive, unpleasant odor as it begins to decompose. This smell intensifies in a compost pile and can linger for weeks, especially if the meat is buried but not actively decomposing. The smell travels—your neighbors will notice, and they have a legitimate reason to complain.

Plant-based compost produces an earthy smell that most people find neutral or pleasant. Meat-based compost smells like rotting food, because that is what it is.

What Happens to Meat in a Compost Pile

Meat does eventually decompose, but the timeline is measured in months or years, not weeks. During that time, it sits in your pile attracting pests and producing odor. The decomposition process is also anaerobic in the meat's when ready area—meaning it happens without oxygen—which produces methane and hydrogen sulfide, the gas that smells like rotten eggs.

By contrast, plant material like vegetable scraps, leaves, and grass clippings breaks down in weeks to a few months and does not attract the same level of pest activity or odor.

Bones and Dairy: Other Animal Products to Avoid

Bones take even longer to decompose than meat—sometimes years—and they are just as attractive to rodents. Dairy products like milk, cheese, and yogurt also belong in the trash. They decompose slowly, attract pests, and can introduce unwanted molds and bacteria into your pile.

Oils and fats from meat or dairy create a water-resistant coating in your compost that slows decomposition of everything around them and can make your finished compost clumpy and unusable.

If You Want to Compost Meat: Commercial Options

Some cities and towns run commercial composting programs that accept meat, bones, dairy, and other animal products. These facilities use industrial-scale equipment and active management to reach and maintain the high temperatures needed to safely process these materials. If your area has a commercial program, you can put meat scraps in a separate container and drop them off at the facility.

Check your city or county waste management website to see if a program exists near you. Some programs charge a small fee; others are free. If no program exists in your area, meat scraps should go in the trash.

Frequently Asked Questions

Can I compost cooked meat?

No. Cooked meat has the same problems as raw meat—it attracts pests, decomposes slowly, and can harbor harmful bacteria. Cooking does not make meat safe for home composting.

What about eggshells and fish emulsion?

Eggshells are fine—they are not meat and decompose without attracting pests. Fish emulsion (a liquid fertilizer) is processed and does not have the same problems as whole fish or fish scraps, so it is safe to use in compost.

Is it okay to bury meat deep in the center of the pile?

No. Rodents will dig down to find it, and the center of a home pile does not stay hot enough long enough to kill pathogens. Burying meat does not solve either problem.

What should I do with meat scraps if I do not have commercial composting?

Throw them in the trash. You can also check whether your city has a food waste collection program—some municipalities collect food scraps separately and send them to commercial facilities.

Can I compost meat if I use a hot composting method?

Hot composting (actively turning the pile to maintain high heat) gets hotter than passive composting, but home hot composting still rarely reaches 160 degrees throughout. Commercial facilities are the only reliable option for meat.
