Hog raisers warned vs ASF spread

As rainy season starts

MANILA, Philippines — Local hog farmers should prepare for the possible spread of African swine fever (ASF) during the onset of the rainy season, the Bureau of Animal Industry said.

The BAI’s National African Swine Fever Prevention and Control Program (NASFPCP) said hog raisers must secure their livestock during heavy rainfall.

It stressed that prolonged exposure to damp and cold conditions may risk the spread of respiratory illnesses, skin infections as well as ASF.

The BAI said rigorous biosecurity, including thorough disinfection and restricted access, are essential to prevent outbreaks.

In line with the threat of further ASF spread, hog farmers are urged to inspect the roofing and walls for leaks and ensure that pig pens are checked to avoid flooding.

Raisers must also maintain proper drainage systems to avoid clogging in the canals, as part of proper biosecurity measures.

“Following intense downpours, livestock owners are advised to inspect their animals immediately,” the BAI said.

Hog raisers must also report any unusual clinical signs observed in their pigs to local authorities or veterinarians to help contain the disease within a limited area and prevent the spread throughout the country.

ASF can spread rapidly from an outbreak location and poses a severe threat to the country’s swine industry, although it does not pose risk to human health.

The virus’ environmental resilience allows it to stay in soil and water and can stay in contaminated pens for up to one month. Transport vehicles, biological vectors like ticks and wild boar populations can also act as virus spreaders.

It can also spread rapidly through direct contact and the ingestion of contaminated food waste or carcasses. The handling of infected pork products and farm equipment may accelerate transmission.

“The spread disrupts the supply chains and affects thousands of Filipino hog raisers who depend on pig farming for their livelihood,” the BAI said.
