Can You Compost Meat Scraps? Safe Practices & Risks Explained

Composting is a win-win for gardeners: it transforms kitchen and yard waste into nutrient-rich soil while significantly reducing household garbage. But when it comes to meat scraps, confusion often arises. Since meat is organic matter, many assume it belongs in the compost pile. The reality is more nuanced.

Is Meat Compostable?

Technically, yes—meat is organic and will decompose. However, most home composting guides advise against adding meat, bones, and dairy. The reasons are practical: these materials attract pests (rats, raccoons, neighborhood dogs), create persistent foul odors, and can harbor dangerous pathogens like E. coli and Salmonella if the pile doesn't reach and sustain high enough temperatures (130–150°F) long enough to kill them.

Why Meat Causes Problems in Home Compost

• Pests: The smell of decomposing meat draws rodents, flies, and larger animals that can scatter your pile and spread disease.
• Pathogens: Home piles rarely maintain the consistent heat required to destroy harmful bacteria. E. coli can survive up to two years in cool compost.
• Odor: Anaerobic decomposition of protein produces putrid smells, especially if the meat isn't buried deep and the pile isn't turned frequently.
• Slow breakdown: Meat breaks down slower than vegetable matter, lingering as a hazard.

If You Still Want to Compost Meat

Some experienced composters do include small amounts of cooked meat (which breaks down faster and smells less) with strict protocols:

• Use a fully enclosed, rodent-proof bin (like a tumbler).
• Bury meat deep in the center of a hot, active pile.
• Keep meat under 5% of total pile volume.
• Turn the pile every 2–3 days to maintain aerobic conditions and heat.
• Monitor temperature daily with a compost thermometer; it must stay above 130°F for at least 3 days.

Commercial Composting: A Different Story

Municipal and industrial composting facilities are engineered to handle meat, bones, and even animal carcasses safely. They maintain sustained high temperatures, controlled aeration, and pathogen testing. The resulting compost is used on commercial crops (hay, corn, tree farms) but is generally not available to home gardeners.

Better Alternatives for Meat Scraps

Instead of risking your home pile, consider:

• Curbside organics collection (if your municipality accepts meat).
• Burying small amounts deep in garden soil (at least 12 inches) away from food crops.
• Using a dedicated anaerobic digester (like a Bokashi bin) that ferments meat waste safely before burying.
• Reducing meat waste through meal planning and freezing leftovers.

For most home gardeners, keeping meat out of the compost pile is the safest, simplest choice. Stick to fruit and vegetable trimmings, coffee grounds, eggshells, and yard waste for a trouble-free, productive compost system.
