African Swine Fever: Biosecure Carcass Disposal and Biosecurity on US Pig Farms

African swine fever (ASF) has never been detected in the United States, but it remains a serious biosecurity threat to American pig producers. The virus is endemic in the Dominican Republic and Haiti, it continues to spread in parts of Europe and Asia, and there is no approved vaccine for use in the US. The virus can persist in infected carcasses, pork products and contaminated materials, making the handling and disposal of dead pigs an important part of a farm's disease-prevention plan.

The USDA Animal and Plant Health Inspection Service (APHIS) maintains strict import safeguards, active surveillance of domestic and feral swine, and public outreach programs to keep ASF out of the national herd. Check current USDA APHIS updates for the latest situation.

For pig businesses, this is a practical reminder: biosecurity depends on multiple controls working together. Secure access, clean vehicles and equipment, safe feed practices, prompt mortality management and an approved disposal plan all matter. And when it comes to disposal, incineration is the option that most directly supports disease prevention. Thermal destruction destroys the ASF virus and reduces carcasses to inert ash on your own site, so there is no off-farm transport, no rendering truck at the gate and no long-term burial site to manage.

Why Carcass Disposal Is a Biosecurity Control Point

ASF can spread through direct contact with infected pigs and through contaminated blood, tissues, faeces, clothing, footwear, vehicles and equipment. Pigs may also become infected by eating contaminated meat or meat products. The virus can survive for long periods in pork products, including frozen and cured products, and infected carcasses can be a source of contamination.

That makes mortality handling more than a routine farm task. If carcasses are left accessible to animals, stored insecurely or moved without suitable controls, they can increase the risk of spreading disease around a unit or beyond it.

A planned disposal route helps you manage routine mortality securely and reduce unnecessary contact with outside collection vehicles. It should be part of a wider farm biosecurity plan, not treated as a substitute for one.

Why Incineration Stands Apart for Disease Control

The USDA APHIS carcass management guidance and university extension research consistently identify incineration as the most biosecure disposal method for disease control. The reasons are straightforward:

• Complete thermal destruction of the pathogen. High-temperature incineration destroys the ASF virus along with the carcass itself, reducing it to a small volume of sterile ash. Rendering, composting and burial do not achieve that on-site: they move, store or slowly process infectious material.
• The waste leaves your farm as inert ash, not as biomass. There is no finished compost, rendered product or buried material to monitor, and no secondary site that could become a contamination reservoir.
• Fewer disease movements, fewer disease vectors. Every renderer visit, haulage trip or shared burial site is a potential contact point between farms. On-farm incineration keeps carcass handling entirely inside your own biosecurity perimeter.
• Immediate disposal, on your schedule. Carcasses can be handled promptly rather than sitting in covered storage awaiting collection, which matters for both the 24 to 48 hour disposal expectations and the secure-storage requirements.
• No groundwater or scavenging risk. Burial carries long-term risks around water sources, cover integrity and scavenger access. Incineration avoids all three.

For disease-prevention value, nothing else matches destroying infectious material completely on the site where it occurs, which is why USDA APHIS identifies incineration among the preferred options in its ASF response planning for disease-control situations where on-site disposal is required.

How an AIS Swine Incinerator Fits Your ASF Prevention Plan

An approved on-farm system can support a controlled mortality-management plan and may reduce the need for routine carcass collection movements. It does not replace visitor control, vehicle cleansing, pest management, secure feed storage or veterinary advice. Nor does it give a farm permission to act outside disease-control instructions.

When considering a swine incinerator, assess daily mortality, peak volumes, the size of the heaviest animal, available operating hours, handling routes and the site's approval requirements. Your equipment must be correctly matched to your operation and maintained in line with applicable rules.

This is where we come in. Agri Incinerators designs, supplies, installs, commissions, maintains and repairs robust incineration systems for exactly this kind of operation, so you get a single accountable partner from system selection through to everyday operation. Here is how the right system strengthens your disease prevention:

• Complete disposal on your site. Mortality is destroyed by thermal treatment inside your own perimeter, which cuts the off-farm carcass movements that pose the highest disease-spread risk.
• High-temperature performance. Our systems are engineered for the complete combustion temperatures animal carcass disposal demands, destroying pathogens rather than storing or transporting them.
• Fuel-efficient, cost-effective operation. Robust monolithic concrete construction holds its heat and keeps fuel consumption down, so the disposal route is economical to run every day of the year, not just in an emergency.
• Built to last. Durable construction and a standard three-year warranty mean the system is ready when your operation needs it, season after season.
• Responsive engineering support. If a unit needs attention, our knowledgeable team provides prompt repairs and maintenance to get you back on track fast, because a disposal route that is down is a biosecurity gap.
• The correct solution, matched to your business. We assess your mortality volumes, pig sizes and operating pattern and recommend the incinerator that fits, maximising efficiency and the fastest possible return on investment.

Agri Incinerators supplies robust pig and swine incinerators for breeder, finisher and AI-stud units across the United States and internationally. Our systems feature robust monolithic concrete construction, fuel-efficient operation and a standard three-year warranty. We bring 40 years' experience in the agricultural industry and provide responsive engineering support for installation, commissioning, maintenance and repairs.

The correct animal carcass incinerator or dead animal incinerator depends on your mortality profile and operating needs. We work with you to match the system to your business, support maximum efficiency and help keep operations on track. Equipment selection and approval are separate matters, so always confirm the applicable regulatory requirements with your state animal health authority.

Build a Practical ASF Preparedness Plan

ASF preparedness is built into everyday farm routines. Set clear access controls, train staff, keep feed and storage secure, maintain vehicle and equipment cleaning procedures, and review how carcasses are handled during routine operations and disruptions.

For suspected disease, official instructions take priority. For routine mortality management, an appropriately approved animal incineration system may form part of a dependable on-farm plan. We offer practical advice, professional installation and ongoing service support, every step of the way.
