California’s dead animal disposal laws put responsibility on the owner or custodian to dispose of a carcass promptly, using burial, cremation, rendering, or an accepting landfill, and following state rules on depth, setbacks, and transport. Get it wrong and you’re looking at administrative fines from $100 to $1,000, a possible misdemeanor for leaving a carcass near a road, and, if the disposal contaminates water, federal Clean Water Act penalties that dwarf everything else.
Who Has to Deal With It
The person who owns or has care or control of the animal is legally responsible for disposal. That covers pet owners, ranchers, boarding facilities, veterinary clinics, and shelters. If a horse dies at a boarding stable, the operator likely shares responsibility through their custodial role, though the split depends on the contract and local rules.
Public agencies take over on public roads. Caltrans removes carcasses from state highways under Streets and Highways Code 91.8, which authorizes removal regardless of whether the animal is domestic, wild, or protected.1California Legislative Information. California Streets and Highways Code 91.8 When practicable, Caltrans tries to notify the owner of a domestic animal and holds identification tags for 30 days. City and county public works or animal control handle local roads.
One common misconception worth clearing up: the California Department of Fish and Wildlife does not remove domestic animals or livestock from private or public property.2California Department of Fish and Wildlife. Living with Wildlife CDFW is a wildlife agency. If a dead dog turns up on your property, call local animal control.
Approved Disposal Methods
California recognizes four disposal methods, and the right choice depends on the animal, the location, and local rules.
- Burial on the property where the animal died, subject to the depth, setback, and groundwater rules described below. Not permitted everywhere; some cities ban it outright.
- Incineration through a permitted facility. Backyard burning of carcasses is prohibited in most jurisdictions, and cremation facilities operate under the California Air Resources Board and local air quality districts.
- Rendering, where the carcass is transported to a licensed plant. The rendering operation must hold a current CDFA license, and hauling dead animals without a valid license or registration is itself a violation.3Cornell Law School. Cal. Code Regs. Tit. 3, 1180.1 – Licensing and Registration Requirements
- Landfill disposal, but only at facilities that accept animal remains. Call ahead. Not every landfill takes carcasses, and large animals in particular are often refused.
The rules tighten for animals that died from a contagious disease. Food and Agricultural Code 9141 requires immediate cremation or burial,4California Legislative Information. California Food and Agricultural Code 9141 and Section 9142 bars transport anywhere except the nearest crematory, so the carcass cannot be trucked past neighbors and pastures on the way to a distant facility.5California Legislative Information. California Food and Agricultural Code 9142
Burial Depth, Setbacks, and Groundwater
If you’re burying on your own property, the numbers matter. CalEPA’s on-site burial guidance calls for at least three feet of soil cover, a minimum distance of 100 feet from any well, and a trench bottom that sits at least five feet above groundwater.6California Environmental Protection Agency. Emergency Animal Disposal Guidance Do not irrigate over the burial site; added water pushes decomposition fluids downward.
For cattle, CalEPA recommends burying mature animals no more than two deep in the trench and applying lime before covering with soil. Keep a record of what was buried, how many, the pit dimensions, and the location. That documentation matters if an inspector shows up.
Avoid floodplains, areas with a high water table, and highly permeable soils. Drainage should flow away from the trench.
Pet Disposal in Residential Areas
For a pet that dies at home, the options are burial, cremation, or interment at a pet cemetery, but local ordinances vary. The City of Los Angeles, for example, prohibits burying any animal except in an established cemetery, so backyard burial of a pet is not legal within city limits.7City of Los Angeles. Los Angeles Municipal Code 53.62 – Animals; Burial Of Check your city or county before assuming a yard burial is fine.
Where burial is permitted, the same depth and setback rules apply. Veterinary offices commonly offer cremation, either individual (with ashes returned) or communal. Individual cremation typically runs $100 to $550 depending on the animal’s size. Communal cremation is cheaper, and no ashes come back.
Livestock and Farm Operations
Rendering is the workhorse option for large animals, and it requires a facility with a current CDFA license.8California Legislative Information. California Food and Agricultural Code 19300 One practical limit: many renderers refuse animals euthanized with barbiturates, because the drugs contaminate the rendered product.
On-farm composting is not yet broadly authorized. The C.A.T.T.L.E. Act (AB-411), introduced in the 2025–2026 legislative session, would permit on-farm composting of livestock carcasses from routine mortality events if the operation follows best management practices for groundwater protection, public health, and food supply safety.9California Legislative Information. Compare Versions – AB-411 Livestock Carcasses: Disposal Until it passes, composting sits under existing waste management rules and generally requires coordination with your county and the Department of Resources Recycling and Recovery.
When rendering service breaks down or heat drives up mortality, CDFA operates a rendering disruption hotline at 916-900-5261.10California Department of Food and Agriculture. Emergency Animal Mortality Preparedness Rendering Service Disruption in the Central Valley Large or unexplained mortality events also trigger the CDFA Animal Health Branch, which investigates to rule out foreign animal diseases. Call before disposing; premature disposal can interfere with the investigation.
Roadkill and Wildlife Salvage
Carcasses on state highways go to Caltrans, which prioritizes removal from travel lanes for safety.11Caltrans. Chapter D1 Litter, Debris, and Graffiti In some regions, Caltrans contracts with local animal control for injured, dying, or dead animals along state routes. On city and county roads, contact your local public works or animal control office.
California also runs a wildlife salvage pilot program. If you unintentionally strike and kill a deer, elk, pronghorn antelope, or wild pig, or come across one already dead on the road, you can legally recover and keep the edible portions by obtaining a wildlife salvage permit under Fish and Game Code 2000.6.12California Legislative Information. California Fish and Game Code 2000.6 Salvage must be done safely and in line with Vehicle Code rules on stopping.
Protected Birds Are Not Trash
A dead hawk in the yard is not a simple disposal question. The Migratory Bird Treaty Act makes it illegal to possess, transport, or sell any migratory bird, including parts, nests, or eggs, without authorization.13Office of the Law Revision Counsel. 16 USC 703 – Taking, Killing, or Possessing Migratory Birds Unlawful Most native species fall under this protection, and picking one up to throw it in the trash technically violates the statute.
Eagles have their own channel. Contact the U.S. Fish and Wildlife Service’s National Eagle Repository at 303-287-2110 or repository@fws.gov. A 2024 final rule allows individuals to salvage eagle specimens and turn them in to the Repository or a federal, tribal, or state wildlife agency, but the Repository must be contacted immediately after salvage.14Federal Register. Regulatory Authorizations for Migratory Bird and Eagle Possession by the General Public, Educators, and Government Agencies If the bird was possibly killed illegally, or if you find five or more dead birds at once, notify the Service’s Office of Law Enforcement before touching anything.
Penalties for Improper Disposal
State enforcement runs on two tracks. Administrative penalties under the Food and Agricultural Code’s animal health provisions range from $100 to $1,000 per violation, tiered as minor ($100 to $300), moderate ($301 to $500), and serious ($501 to $1,000).15Cornell Law School. Cal. Code Regs. Tit. 3, 839 – Administrative Penalty Schedules
Criminal exposure comes through Penal Code 374d, which makes it a misdemeanor to leave a dead animal within 100 feet of any street, alley, or public road.16California Legislative Information. California Penal Code 374d Standard California misdemeanor penalties apply: up to six months in county jail and a fine of up to $1,000.
The biggest risk is the one most people don’t see coming. If improper disposal contaminates waterways, the Clean Water Act authorizes civil penalties of up to $68,445 per day per violation under the current inflation-adjusted schedule.17eCFR. 40 CFR 19.4 – Statutory Civil Monetary Penalties, as Adjusted for Inflation Burying a large carcass too close to a creek is enough to put federal jurisdiction on the table.
