ROXAS, Isabela: Two towns in Isabela have confirmed cases of African swine fever (ASF) as agriculture and local government officials have initiated checkpoints at the entry and exit points in the province. The Department of Agriculture Cagayan Valley confirmed ASF cases in Mallig and Quirino towns, two areas near the ASF-affected Tabuk City in neighboring Kalinga province. Regional Director Narciso Edillo said they deployed law enforcement teams at the entry and exit points to and from Isabela. These are situated at the boundaries of Kalinga, Ifugao and Benguet provinces. Edillo also said they have been probing claims that the hogs were affected by ASF-infected pigs from Kalinga. A fumigation was also conducted in the affected areas in the said towns.
