Monday's culling was witnessed by representatives from the Food and Agricultural Organization (FAO), the the World Health Organization (WHO), animal welfare observers, Bulacan Gov. Joselito Mendoza and Pandi Mayor Roberto Oca. The slaughter has been estimated to cost 16 million Philippine pesos (₱), which include hog farm owners' compensation and the cost of culling for five to seven days.

"As of late Tuesday the depopulation teams have culled 2,663 pigs, compared to 442 on Sunday, 795 on Monday and 1,426 on Tuesday; as of early afternoon on Wednesday, the numbers have reached 3,482," said Dr. Davinio Catbagan. According to Agriculture Secretary Arthur C. Yap, the culling team has slaughtered 2,078 pigs, bringing the total to 4,741 on Wednesday. The number of hogs had increased to 6,500 from 6,000 as some mother pigs gave birth amid the depopulation.

But according to Dr. Joy Gomez, provincial public health officer of Bulacan, six members of the depopulation team at the Pandi "Win Farm" have complained of fatigue, headache and dizziness, and have been closely observed by a team of doctors.

The state will compensate the farmers, however "it cannot be [100% of the market price.] A range of about 25%-50%, but it has to be discussed [with the farm owner]. At 25%-50%, the government may pay the farm owner ₱6.28 million-15.625 million, plus the cost of animal culling operations," said Yap.
