President Rodrigo Duterte declared a nationwide state of calamity in the Philippines due to African Swine Fever (ASF) that has hit the local hog industry and push up pork products prices.
It is stipulated on Presidential Proclamation No. 1143 that the country is placed under the state of calamity for a year, unless lifted or extend as announced by the Malacañang on Tuesday, May 11.
The declaration authorizes the use of sufficient funds, including the Quick Response Fund, by national and local governments to contain ASF.
An ASF case was first reported in September 2019 and has since spread to 12 regions, 46 provinces, and 493 cities and municipalities in the country, with new cases being continuously reported despite government interventions.
The said disease which is not transmittable to humans, has caused the country’s swine population to drop by about 3 million hogs, resulting in more than P100 billion in losses and an increase in inflation.
