In mid-2007, an outbreak of classical swine fever or hog cholera had affected the Central Luzon region of the Philippines, particularly in the provinces of Bulacan and Pampanga, as confirmed by the Department of Agriculture.
Bulacan, which lies immediately north of Metro Manila, is the center of hog raising in the Philippines.
Bartolome also dismissed the cases of foot-and-mouth disease in the province, and the hog cholera only affected about 3,000–5,000 sows.
