African Swine Fever (ASF) is one of the most destructive livestock diseases affecting pig producers in South Africa. While the disease poses no risk to human health, it spreads rapidly through infected animals, contaminated equipment, vehicles, footwear, clothing and feed, often resulting in widespread culling and significant financial losses.
Recent outbreaks in Gauteng, where more than 69,000 pigs have reportedly been affected, demonstrate why proactive biosecurity remains the most effective defence against disease transmission.
Ecowize partners with producers, agricultural businesses and industry stakeholders to strengthen biosecurity through hygiene risk assessments, scientifically validated cleaning and disinfection programmes, staff training and operational support. These proactive measures help reduce contamination risks and improve resilience against disease outbreaks.
Understanding African Swine Fever
African Swine Fever is a highly contagious viral disease that affects both domestic and wild pigs. Unlike Swine Influenza, ASF cannot be transmitted to humans, and pork products remain safe to consume when sourced through regulated supply chains.
The challenge facing producers is that there is currently no effective treatment for infected animals, and disease control relies heavily on strict biosecurity, surveillance, movement controls and, where necessary, humane culling. Once the virus enters a farm, containing its spread becomes significantly more difficult and considerably more expensive than preventing its introduction in the first place.
This is why biosecurity should never be viewed as a response to disease. It must be embedded into everyday farming operations.
Every Entry Point Is a Biosecurity Risk
Many producers think of biosecurity as disinfecting vehicles or installing footbaths, but effective disease prevention requires a far more comprehensive approach.
African Swine Fever can be introduced through contaminated equipment, delivery vehicles, visitors, contractors, feed, wildlife, pests or employees moving between production areas. Each movement presents another opportunity for pathogens to spread.
Drawing on decades of experience across South Africa’s agricultural and food production sectors, Ecowize develops practical biosecurity programmes that address these risks through controlled access procedures, hygiene zoning, cleaning verification, vehicle sanitation, pest management and structured operational controls. By reducing opportunities for contamination at every stage of production, farms can significantly improve their resilience against disease outbreaks.
Cleaning Alone Does Not Prevent Disease
One of the biggest misconceptions about biosecurity is that cleaning alone is sufficient. In reality, effective disease prevention depends on following a structured cleaning and disinfection process.
Organic matter such as manure, soil and feed residues can protect viruses from disinfectants if surfaces are not cleaned correctly. Only after these contaminants have been removed can disinfectants perform effectively.
Ecowize applies scientifically validated cleaning methodologies based on the principles of the Sinner Circle, ensuring the correct balance of chemistry, mechanical action, temperature and contact time. Chemical concentration verification (CCV), appropriate disinfectant selection and routine verification further strengthen hygiene performance and help ensure cleaning programmes consistently achieve the required standard.
Biosecurity Depends on People
Even the most advanced biosecurity programme will fail if people do not understand or follow established procedures.
Employees, contractors and visitors all influence disease prevention through everyday activities such as vehicle movement, equipment handling, PPE use and personal hygiene. Consistent training, supervision and clearly documented procedures help reduce human error and strengthen operational discipline.
Ecowize works closely with businesses to develop practical training programmes, hygiene audits and risk assessments that build a culture of biosecurity across every level of the operation. Rather than reacting to disease outbreaks, producers can identify opportunities for improvement before they become costly operational failures.
Building More Resilient Farming Operations
The recent African Swine Fever outbreaks in Gauteng highlight the importance of reviewing biosecurity programmes before disease reaches the farm gate. Every producer should regularly evaluate access controls, hygiene procedures, equipment sanitation, pest management, staff training and cleaning verification to ensure biosecurity measures remain effective.
Proactive investment in hygiene not only reduces disease risks but also protects productivity, animal welfare, operational continuity and long-term business sustainability.
Biosecurity Is an Investment, Not a Cost
African Swine Fever continues to present a significant challenge for South Africa’s pig industry, but outbreaks are not inevitable. Well-designed biosecurity programmes, supported by effective hygiene management, validated cleaning and disinfection, and operational discipline, remain the strongest defence available.
Ecowize partners with agricultural businesses to implement practical, science-based biosecurity solutions, including proven products such as Agrisan Extra for effective cleaning and Virucidal WP for broad-spectrum virucidal disinfection. Combined with robust hygiene protocols and expert operational support, these solutions help protect livestock, strengthen disease resilience and safeguard the future of farming operations.
Protecting livestock begins long before disease is detected. If your business wants to strengthen biosecurity through validated cleaning programmes, operational risk assessments, hygiene audits and staff training, speak to the Ecowize team about developing a practical biosecurity solution tailored to your operation.
Frequently Asked Questions
1. What is African Swine Fever (ASF)?
African Swine Fever (ASF) is a highly contagious viral disease that affects domestic and wild pigs. It does not infect humans but can cause severe illness and high mortality rates in pigs, making it a major threat to the pork industry.
2. How does African Swine Fever spread?
The virus spreads through direct contact with infected pigs, contaminated equipment, vehicles, clothing, footwear, feed and pork products. Strict biosecurity measures are essential to prevent the virus from entering or spreading within a farm.
3. Is there a vaccine or treatment for African Swine Fever?
There is currently no widely available vaccine or effective treatment for African Swine Fever in South Africa. Disease control relies on strong biosecurity, early detection, movement controls and the humane culling of infected animals where required.
4. Why is biosecurity important for preventing African Swine Fever?
Biosecurity reduces the risk of disease entering or spreading within a farming operation. Effective measures include controlled site access, cleaning and disinfection, staff training, vehicle sanitation, pest management and ongoing hygiene monitoring.
5. How can Ecowize help protect agricultural operations?
Ecowize partners with producers, agricultural businesses and industry stakeholders to strengthen biosecurity through hygiene risk assessments, scientifically validated cleaning and disinfection programmes, staff training and operational support. These proactive measures help reduce contamination risks and improve resilience against disease outbreaks.
