African Swine Fever: Characteristics, Spread, and Containment Solutions Through Carcass Incineration
Introduction to African Swine Fever
African Swine Fever (ASF) is a highly contagious viral disease that affects both domestic and wild pigs. It poses a serious threat to the global swine industry. Although the disease is not zoonotic (i.e., it cannot be transmitted to humans), its economic and environmental impact is devastating. ASF spreads rapidly through direct contact between infected and healthy animals, as well as through environmental vectors such as contaminated food, equipment, and vehicles.
Characteristics of the African Swine Fever Virus
The African Swine Fever virus belongs to the Asfarviridae family, genus Asfivirus. It is a large DNA virus characterized by exceptional resilience in the external environment. The virus can survive for weeks or even months in pork products and tissues of deceased animals, making the prompt and safe management of infected carcasses essential.
Symptoms of ASF
The most common symptoms of ASF in pigs include:
• High fever
• Internal hemorrhages
• Skin lesions
• Respiratory distress
• High mortality rate, up to 100% in affected farms
Currently, there are no effective vaccines or treatments for ASF, making preventive measures and containment strategies essential.
Modes of Transmission of African Swine Fever
ASF spreads primarily through:
• Direct contact between infected and healthy pigs.
• Indirect contamination via materials, vehicles, and people.
• Infected pork and pork products that are not properly treated.
• Movement of wild animals, such as wild boars, which act as natural reservoirs of the virus.
In many countries, including Italy, ASF has widely affected wild boars. To address the emergency, government authorities are promoting the construction of new incineration plants to ensure the safe disposal of carcasses and reduce the risk of infection.
Solutions for Managing Infected Carcasses
One of the Most Effective Solutions to Contain ASF: Safe Disposal of Infected Carcasses
Safe disposal of infected carcasses is one of the most effective measures to contain African Swine Fever (ASF). This process prevents the spread of the virus by completely eliminating contaminated biological material.
Dangers of Burying Infected Carcasses
Burying infected carcasses is a practice that poses significant environmental and health risks. While it may seem like a quick and cost-effective solution, it comes with several major disadvantages:
• Soil and groundwater contamination: Liquids from the decomposition of carcasses can seep into the ground, contaminating underground water sources.
• Virus persistence: The ASF virus can survive for a long time in buried carcasses, keeping the threat of new outbreaks alive.
• Wild animal access: Wild boars and other animals can dig up and bring infected carcasses back to the surface, facilitating virus spread.
• Emission of harmful gases: The anaerobic decomposition of carcasses produces gases that are potentially hazardous to the environment and public health.
A report by EFSA (European Food Safety Authority) highlights that carcass incineration is one of the most effective solutions to prevent the spread of ASF.

Carcass Incineration: The Safest Solution
Carcass incineration is a highly secure method for eliminating the ASF virus. There are two main types of incineration:
1. Static Incinerators
Fixed furnaces are permanent structures located at authorized facilities for the disposal of biological waste.
Advantages of Static Incinerators:
• Large-scale management: Capable of handling large quantities of carcasses.
• Emission control: Advanced filtration systems to protect the environment.
• Efficient processes: Monitored to ensure safety and regulatory compliance.
2. Mobile Incinerators
Mobile furnaces are versatile solutions that can be transported directly to infection sites.
Advantages of Mobile Incinerators:
• Quick intervention: Eliminates risks associated with carcass transportation.
• Flexibility: Ideal for remote or hard-to-reach areas.
• Immediate efficiency: Enables rapid response to outbreaks.
