Philippines' African swine fever calamity

Philippine President Rodrigo Duterte has declared a one-year nationwide state of calamity due to an outbreak of African swine fever (ASF), which has resulted in more than $A2.6 billion in industry losses.

In a proclamation signed on Monday, Duterte said ASF has spread in more than half of the Philippines, causing a "significant reduction in the country's swine population by around three million hogs" and an increase in retail prices of pork products.

The outbreak has resulted in losses of more than 100 billion pesos ($A2.66 billion) in the local pig sector and related industries, the proclamation noted.

"There is an urgent need to address the continued spread of ASF and its adverse impacts, to jumpstart the rehabilitation of the local hog industry, and to ensure the availability, adequacy and affordability of pork products, all for the purpose of attaining food security," it said.

Duterte directed all government agencies and local government units to mobilise resources to undertake measures to contain the spread of ASF, address the supply deficit in pork products, and reduce retail prices.

The state of calamity declaration will allow the national and local governments to tap funds for the response to the outbreak.

Since the first case was reported in 2019, ASF has been detected in 46 of 81 provinces in the Philippines, and new cases were still being reported despite high-level interventions, the government said.
