Dead Animal Disposal in Wisconsin: The Statute, the DNR's Instruction, and Your City's Cart

Wisconsin has no single dead-animal disposal law. Three sets of rules apply, and which one you are under depends on what the animal was. The table sorts it. The sections below quote the statute, the code and the guidance behind each line.

One boundary matters more than any other. § 95.50(1)(a) defines a carcass as "the dead body, or any part of the dead body, of a livestock animal or other domestic animal." A dead raccoon or deer in your yard is not under that 24-hour clock on the face of the statute, and no Wisconsin agency has published a statement saying otherwise. Sites that quote the 24/48-hour rule as a homeowner wildlife deadline are quoting it wider than it reads.

Wis. Stat. § 95.50(3) reads: "No person who owns or controls a carcass, or who owns or controls the land on which a carcass is located, may leave the carcass exposed to access by dogs or wild animals for more than 24 hours during the months of April to November or for more than 48 hours during the months of December to March if the person knows or reasonably should know that the carcass is exposed." The duty falls on the landowner as much as on the animal's owner, and it is an exposure rule: a carcass covered and secured is not the same as one lying in the pasture.

The section lists no burial depth, no setback from a well and no approved method. It prohibits two things only: disposing of a carcass "in the waters of the state," and handling a diseased carcass "in a manner that creates a significant and foreseeable risk of transmitting disease to humans or animals." DATCP's Livestock Carcass Disposal page says "Rendering, burial, burning and landfilling have been the typical means of disposal" and "We recommend composting." It also says that putting a carcass "on the back 40 to rot and/or be eaten by scavengers" is not composting and "Is illegal." For a farmer, § 289.43(9) bars the DNR from regulating a carcass buried under § 95.50 on the farmer's own property. That exemption is written for farmers only; it says nothing about a homeowner's yard either way.

§ 95.99 is the only dollar figure on this page. A first offense carries a fine of "not more than $1,000," or, in its place, a forfeiture of "not less than $200 nor more than $5,000." A dog or cat is a domestic animal, so this is the section that reaches a pet; who to call for one is in the pet guide.

No Wisconsin statute sets a homeowner deadline or method for a dead wild animal. What the Wisconsin DNR publishes on its Wildlife Health page is practical: "To dispose of a wild animal carcass, use gloves or an inverted plastic bag to move it and either bury the carcass on your property or double-bag it in a garbage bag and place it in your trash. Do not handle dead wildlife with your bare hands."

Two things the page does not say. It gives no burial depth and no distance from a well or a lake, and it does not promise that your hauler will take the bag; that is a city rule, covered below. The DNR asks for a report only of "five or more sick or dead wild birds or three or more sick or dead wild mammals in one area," through the Wildlife Switchboard at 608-267-0866. A single carcass needs no report, and a report does not bring a crew: the DNR's own deer page says "in most cases, the department does not have the resources to remove dead animals, including deer."

For a raccoon or skunk you would rather not touch, or anything under a deck or in a crawl space, the yard removal page is the private route.

Deer are the one species with a full state regime. The DNR's Deer Carcass Disposal FAQ (PUB-WA-1881) says that "according to Wisconsin statute s. 289.01(33), deer carcasses are defined as solid waste," and that "landfilling is the preferred option for carcass disposal." The DNR's carcass page gives a non-hunting landowner four choices, in its words: "bury it on their property, utilize a deer carcass waste dumpster if during the fall season, leave it where it lays or contact their local municipality to request it to be picked up (this is not guaranteed)."

Burial is allowed for one carcass, where it died. The FAQ: "you may legally bury a single carcass on private property where the waste was generated with permission from the landowner. The carcass should be buried deep enough to prevent excavation by scavengers," and "Do not bury carcasses in wetlands or where they may cause a detrimental effect to surface or ground water." No depth in feet exists in any Wisconsin source; "deep enough to prevent scavengers" is the rule.

Landfills may take a carcass but are not required to. Wis. Admin. Code NR 506.07(1)(d) tells a landfill that "Putrescible materials such as spoiled foods and animal carcasses shall be immediately compacted and covered," and the prohibited-items list in NR 506.095 (lead-acid batteries, appliances, waste oil, yard waste, tires) does not include carcasses. Acceptance is set per facility; the DNR says plainly that "not all landfills and transfer stations accept deer carcass waste," so call the scale first. Two seasonal routes exist for hunters. Winnebago County's Deer Carcass Disposal Program at its Oshkosh landfill waives the scale fee October 1 through December 31 for "Winnebago County residents who process their own deer"; whether it takes a deer that died in a yard is not stated. The DNR's Adopt-a-Dumpster program places sponsored carcass dumpsters during deer season, mapped on the DNR's deer waste disposal page.

Three limits. The DNR "recommends not transporting whole deer carcasses to areas outside the county or adjacent county where the animal was harvested"; the current page words it as a recommendation. "It is illegal to dispose of carcass waste on public lands, roadways or private property without permission." And a deer killed by a vehicle must be registered with the DNR before it leaves the scene, which the roadkill guide covers. For a deer you cannot lift, the deer removal page is the private route.

Whether the bag goes in the cart is decided by your city and its hauler, not the state. The DNR says only that "Many communities accept single carcasses in curbside pickup for residents" and, for homeowners, "work with your waste hauler prior to placing deer waste in your bin." Here is what the nine launch cities publish, in their own words.

Local deadlines exist too. Milwaukee's code gives "any person owning or having charge or control of any dead animal" 12 hours to remove it from the city (s. 78-49); Appleton declares a carcass not buried or disposed of "within twenty-four (24) hours after death" a public health nuisance (Sec. 12-28). The Legislature's model town Public Nuisance Ordinance covers "unburied animal carcasses" and leaves the time limit blank for each town to fill in, so a rural township may have a clock of its own. It is a template, not law, until a town adopts it; ask the clerk.

If you haul a carcass on a public road, § 95.72(7)(b) applies to everyone: a dead animal may not be transported "unless it is transported in a closed vehicle or container or unless it is completely covered with a tarpaulin or other suitable material," and containers "shall be leakproof." The hauler license in the same section exempts "persons transporting dead animals for destruction or burial," so a homeowner making one trip does not need one.

Landfills and transfer stations set their own acceptance, hours and fees, and most Wisconsin counties publish nothing about carcasses. Two that do point in different directions: Dane County's landfill routes "Animal Carcasses" through a special-waste form, while La Crosse County's 2026 solid-waste guidelines list "Animal Remains" as unacceptable at the resource recovery facility that takes the county's household waste. Call before you load; the scale operator's answer is the one that counts.

Handling a small animal with gloves and a bag is what the DNR expects. The cases that are not that: a deer you cannot lift or drive, a raccoon or skunk you should not touch, anything under a deck, in a crawl space or in a chimney, or a smell whose source you cannot find. A carcass inside a finished wall is informational on this site; no operator here promises to open drywall.

Any private-property work in Wisconsin would be performed by an independent operator, if one is available for the address. Availability is checked on the call, and the price depends on the animal, where it is, access and disposal; it is quoted on the call and never on a page here. Where a city publishes a public route, none of the pages reviewed states a fee or calls it free, and the who-picks-up guide sorts road and curb cases by jurisdiction.
