38: 437-450. As a general guide, 3 to 5 cubic yards of co-composting material is required for every 1,000 pounds of carcass (Auvermann et al., 2006). Ithaca, N.Y.: Northeast Regional Agricultural Engineering Service (NARES). (NDSU photo). As per 2016 U.S. Department of Agriculture-HPAI response mortality composting guidelines, suitable carbon sources are key for proper windrow or pile preperatrion and maintaining a consistent temperature during composting. Complete destruction of pathogens and weed seeds occurs by maintaining thermophilic conditions during the active composting period. Factsheets in this series were prepared by, Masoud Hashemi, Stephen Herbert, Carrie Chickering-Sears, Sarah Weis, Carlos Gradil, Steve Purdy, Mark Huyler, and Randy Prostak, in collaboration with Jacqui Carlevale. (6) Incineration. NDSU Extension Service publication AS1781. Boston. 30: 376-386. Journal of Environmental Quality. Construct a windrow 10 feet wide by 4 feet deep of the dry manure and bedding mixture. Left untouched, an adult carcass will compost in five to six months. 2009. Resources from UMass Extension and the Center for Agriculture, Food and the Environment: ag.umass.edu/coronavirus. This publication serves as a reference for producers regarding options of carcass disposal. How much does that incinerator cost? In addition, rendering might not be an option for some producers, depending on location, type and volume of mortalities. Methods and processes of dealing with dead animals have always been and continue to be a concern in all animal production operations both large and small, slaughter plants, and other facilities that have animals. Carcasses can be added anytime but should be spaced about 4 feet apart. Placing a fresh (warm) carcass in a compost pile will help speed the decomposition process versus placing a cold carcass in the pile. But the challenges of disposal by burial may include identifying suitable on-farm burial sites due to the risk of groundwater contamination. Research Institution. Locate it on a solid spot where the ground slopes 1 to 2%. Soil contamination caused by emergency bio-reduction of catastrophic livestock mortalities. Therefore, selection and maintenance of a burial site is very important. Use a compost-style dial thermometer, ideally with a 30-inch long probe, to monitor the temperature. Glanville. Safe disposal of carcasses is an important issue for day-to-day, routine management of livestock and poultry mortalities to prevent disease transmission and to protect air and water quality. Windrows are aerated primarily via natural air movement or passive air movement (Rynk, 1992). Place the mortality on the base material. This document does not explain requirements that apply to veterinarians or commercial chicken or duck operations. Burning carcasses in a pit on the site is an acceptable method of disposal in North Dakota. The bulking material, such as cornstalks and tree trimmings, needs to provide porosity and structure to a compost pile; therefore, manure is not the ideal choice. Each of these options is described briefly in the following sections. Figure 3. For small- and medium-sized carcasses (for example, poultry, pigs, sheep) the active composting period (phase I) may be up to three months before the pile is turned (Keener et al., 2000). 2003. Procedures and equations for sizing of structures and windrows for composting animal mortalities. Site it lengthwise with the slope of the land so runoff and snow can’t puddle against the windrow. However, for a large carcass (mature beef and dairy cattle, horses or other large animals), the active composting phase may be up to six months (Auvermann, 2006). Animals and wildlife are good at finding access points into warm houses, basements, attics, and even cars, and this can create problems if the animal is sick, ill, or can't escape. Once you’ve placed a carcass (might want to puncture the rumen on cattle to avoid a gas buildup and possible explosion), cover it with at least 2 feet of the same manure and bedding mixture that is underneath the carcass. Feel free to use and share this content, but please do so under the conditions of our, Animal Carcass Disposal Options Rendering • Incineration • Burial • Composting, 5 easy steps for composting dead livestock. MA 02114. However, frequent turning of an active compost pile during a disease outbreak may increase the risk of generation and release of airborne particulates that can carry infectious microbes (Xu et al., 2009). The rendering market has changed in recent years because the price of meat and bone meal has decreased and the use of many rendered byproducts has been eliminated due to concerns related to transmissible bovine spongiform encephalopathies (BSE or mad cow disease). Phone (617) 626-1700. This is a step-by-step look at the composting pile construction procedure: laying the straw base and measuring the perimeter after laying carcass. However, large distances between rural areas and rendering plants and the lack of a timely pickup service of dead animals from farms are the biggest challenges for using rendering as a mortality disposal method. The turning operation mixes the composting materials and enhances passive aeration. Northeast Regional Agricultural Engineering Service. (A) Incineration of dead animals shall be accomplished in an approved incineration facility, or by a mobile air curtain incinerator at a site approved by the Executive Director. Alternatives include natural disposal, burying, landfills, incineration, and composting. The Food and Drug Administration (FDA) requires removal of brain and spinal cord specified risk material (SRM) from rendered products intended for animal food. Typically, a minimum 12- to 16-inch layer of co-composting material around all sides of the carcass will discourage predators, control odors and eliminate flies. How Can You Eliminate the Odor of a Dead Animal? Once you’ve placed a carcass (might want to puncture the rumen on cattle to avoid a gas buildup and possible explosion), cover it with at least 2 feet of the same manure and bedding mixture that is underneath the carcass. Next, treat the area with a disinfectant, odor neutralizer, or masking agent and ventilate the site with a fan (preferably one that forces stagnant air out the windows). The following is a brief discussion of each disposal option. Use a long-handled shovel to pick up the dead animal and place it into a plastic bag. 198: 285-295. Thomas. Rynk, Robert, et.al 1992. Place the carcass on a bed of wood chips 2 feet deep, then cover it to a depth of about 4 feet, with at least 2 feet on the sides. Open-pit or open-pile burning should be a method of last resort. Burial must be at least 100 feet from a private well, 200 feet from a public well, 50 feet from an adjacent property line, 500 feet from a residence and more than 100 feet from a stream, lake or pond. 2007. 5 Burning dead animals. When the air temperature is above 50 degrees and the pile is turned when its temperature drops below 120 degrees, the soft tissue in a 1,500-pound cow will finish composting as quickly as two to three months. Overview of Animal Feeding Operations Iowa has two types of DNR-regulated animal feeding operations (AFOs): confinements and open feedlots. In the process of rendering, the carcasses are exposed to high temperatures (about 130 C or 265 F) using pressurized steam to ensure destruction of most pathogens. Suitable carbon sources vary, but may include straw, waste feed/hay, sawdust, poultry litter or finished compost. Disposal of dead animals on a farm should . Website: www.mass.gov/agr. Carcasses are ground up before chemicals or steam is introduced. 5 easy steps for composting dead livestock. This publication has been funded in part by the Massachusetts Department of Agricultural Resources and the Massachusetts Farm Bureau Federation, Inc. UMass Research and Education Center Farms, Conservation Assessment Prioritization System (CAPS), Extension Risk Management/Crop Insurance Education, North American Aquatic Connectivity Collaborative, Civil Rights and Non-Discrimination Information. This FDA regulation is aimed at protecting against the transmission of transmissible spongiform encephalopathies such as BSE, but rendering facilities charge additional fees for the processing requirement. Hao, X., Chang, C., Larney, F.J., and Travis, G.R. Composting of carcasses is recognized as an effective method by the biosecurity agencies in the U.S. and other countries to manage routine and emergency management of mortalities (Wilkinson, 2007). "Basically, it looks like a pile of mulch," he said. 2007. The cover material may settle or be disturbed by wind, so be sure to check the pile periodically. Cooperative Extension. Also, it's probably not a great idea to go around reading articles called things like Do not touch the animal. AgriLife Extension Bulletin, Texas A&M University, B-6209. In many areas, the numbers of rendering facilities are limited and in many cases are declining due to increased costs and biosecurity risks associated with transporting mortalities (Glanville et al., 2009). The Missouri Dead Animal Disposal Statute was passed by the 86th General Assembly and … This is a step-by-step look at the composting pile construction procedure:  breaking up a round straw bale. Rendering is the process of converting dead animal bodies to pathogen-free useful byproducts such as protein for agricultural feed. Greenhouse gas emissions during co-composting of calf mortalities with manure. Burial is a common method of carcass disposal to manage mortalities, but it poses a groundwater contamination risk if the burial site is not selected and managed properly. However, during mortality composting, piles are left undisturbed during the first stage of composting (phase I) to ensure soft tissue is decomposing properly. Minicomposters are used for small-carcass (for example, poultry) composting and are not suitable to handle large volumes of animal mortalities. Incineration is a preferred method for managing small carcasses (for example, poultry and swine), but often large carcasses and/or a large number of mortalities cannot be handled due to the small incineration capacities (mostly are limited to less than 300 pounds per head) of most on-site farm incinerators. Materials are turned using a bucket loader. Virginia Coperative Extension. Department of Agricultural & Biosystems Engineering, ISU. At least three bins usually are in operation at any time. Composting is the preferred method of carcass disposal because it can be implemented rapidly on farms at minimum cost. A layer of 6 to 12 inches of soil can be placed between layers of carcasses. Step One. Composting is a naturally occurring process in which the dead animal is broken down into basic elements (organic matter) by microorganisms, bacteria and fungi. Journal of Applied Microbiology. Producers must take special precautions with the disposal of diseased animals because states may have stricter and different mortality handling and disposal requirements pertaining to certain infectious diseases. Small and medium-sized carcasses can be composted in a three-sided enclosure (for example, a bin) constructed on compacted clay soil or a concrete floor (Figure 2). Burning is not recommended as livestock are attracted to any remaining ash or carcass which can spread the disease and cause multiple stock deaths. 45: 6.19 - 6.25. Or they can be left in the pile. Composting has been shown has a viable means of disposing of dead livestock, horses and birds. Manure may be used if enough bedding is incorporated with it. Here are some simple steps on how to safely dispose of a dead animal. The Burn Easy Incinerator has a patented, thermostatically controlled system that shuts the burner down when the chamber reaches the desired level. Anthrax. For more information visit the UMass Extension Crops, Dairy, Livestock and Equine Program They need to think about mortality management before a death occurs to avoid having problems after the fact.

The biosecurity of on-farm mortality composting. For burning, Akdeniz says mortalities should be incinerated according to EPA guidelines. Carcass composting is considered one of the best disposal options due to its greater affordability, better biosecurity and low inputs and investment requirements, but composting needs proper management for complete decomposition and to ensure that objectionable odors are not generated. Therefore, carcass disposal remains one of the major problems facing livestock and poultry producers. NDSU Extension publication V561. Transporting carcasses for offsite disposal Deep burial pits should be constructed following the guidelines provided earlier in this document. Ames. The Massachusetts Department of Environmental Protection, for instance, does not require a permit. When you see no more soft animal parts, you can spread the compost or leave it in place.

If at all possible, don't touch a dead animal or at least wear gloves. Suite 500. Proper composting techniques will destroy most disease-causing bacteria and viruses. Typically, compost thermometers (36- or 48-inch stem length) or wireless/wired temperature probes should be inserted at an 45-degree angle to 18 and 36 inches in depth in the compost piles for monitoring pile temperature above and below the carcasses layer. Maintain a stockpile of the material for covering. The vertebral column and spinal cord of cattle 30 months and older are considered to be SRM. On-farm composting of dead animals generated on the same farm as the composting facility is exempt from having a permit if operated in compliance with the Massachusetts Department of Agriculture regulations. Put on gloves before handling the plastic bag. For instance, if you bury an animal, make sure vultures can't get to it, especially if the animal was at risk for a disease. In North Dakota, in the case of any infectious or contagious disease, a carcass must be disposed of within 36 hours or transferred to a licensed rendering plant.
