African Swine Fever Found in Gyeonggi Province Feed Additives | ASF Update

Recent investigations in Gyeonggi Province, South Korea, have revealed the presence of the African swine fever (ASF) virus in some plasma protein feed additives, raising concerns about potential transmission routes for this highly contagious and devastating disease affecting pigs.

ASF is a viral disease that impacts both domestic and wild pigs, often with a mortality rate reaching 100%. While it poses no threat to human health, the economic and social consequences of ASF outbreaks are substantial. The virus is remarkably resilient, capable of surviving on various materials like clothing, boots, and vehicle wheels, and can persist in processed pork products such as ham and sausages. This durability contributes to the ease with which the disease can spread across borders.

The Global Reach of African Swine Fever

ASF has been a growing concern globally since August 2018, with reported cases across a wide range of countries in Asia and the Pacific. These include China, Mongolia, Vietnam, Cambodia, North Korea, Laos, Myanmar, the Philippines, South Korea, Timor-Leste, Indonesia, Papua New Guinea, India, Malaysia, and Bhutan. The spread of ASF has had a particularly detrimental effect on small-scale pig farms, which often serve as a crucial source of income and livelihood for families and contribute to upward economic mobility.

The World Organisation for Animal Health (WOAH) emphasizes the significant socio-economic burden imposed by ASF. Beyond the direct losses in pig populations and the disruption of the pork industry, the disease can limit access to essential services like healthcare and education for affected communities. Pork represents a substantial portion of global meat intake – exceeding 35% – making ASF a threat to food security as well.

Understanding the Virus and its Spread

The discovery of the ASF virus in feed additives highlights a potential pathway for the disease’s propagation. The virus’s ability to survive in various pork products, even processed ones, underscores the importance of stringent biosecurity measures throughout the entire pork supply chain. This includes careful sourcing of feed ingredients, thorough disinfection protocols, and strict controls on the movement of pigs and pork products.

The FAO (Food and Agriculture Organization) provides ongoing situation updates regarding ASF in the Asia & Pacific region, monitoring outbreaks and disseminating information to help countries respond effectively. These updates are crucial for coordinating regional efforts to contain the disease and mitigate its impact.

Impact on Livelihoods and Food Security

The consequences of ASF extend far beyond the immediate economic losses for pig farmers. As WOAH points out, the disease can destabilize rural economies and hinder progress in improving living standards. The loss of income from pig farming can force families to make difficult choices, potentially impacting their access to healthcare, education, and other essential resources.

the reduction in pork production due to ASF can lead to higher meat prices and reduced availability, affecting consumers and potentially exacerbating food insecurity, particularly in regions where pork is a staple food.

Current Situation and Future Strategies

The recent outbreak in South Korea, coupled with the discovery of the virus in feed additives, underscores the need for heightened vigilance and proactive measures to prevent further spread. Authorities are likely conducting thorough epidemiological investigations to trace the source of the contamination and implement appropriate control measures.

Ongoing research into ASF vaccines is a critical area of focus. While a fully effective and widely available vaccine remains elusive, advancements are being made in developing potential vaccine strategies. A successful vaccine would be a game-changer in the fight against ASF, offering a more sustainable and long-term solution for controlling the disease.

The situation remains dynamic, and continued monitoring, research, and international collaboration are essential to effectively address the challenges posed by African swine fever. Strict adherence to biosecurity protocols, responsible feed management practices, and ongoing surveillance are crucial for protecting pig populations and safeguarding food security.
