In Administrative Order (AO) 22 signed on Feb. 5, President Rodrigo R. Duterte ordered all concerned government agencies and offices to “strictly implement and ensure compliance with the ‘National Zoning and Movement Plan for the Prevention and Control of African swine fever (ASF), as contained under DA Administrative Circular No. 12 (s. 2019)” to control and contain the spread of the fatal disease.
On Dec. 10, 2019, the DA issued Administrative Circular, which formally orders the establishment of zones across the country, depending on the level of risk in relation to ASF.
