Department of Agriculture Administrative Order number 9 signed by Secretary Proceso Alcala removes ' the use of carbon monoxide coming from vehicle exhaust fumes' as a legal procedure of euthanizing animals. Only "carbon monoxide in cylinders may be used."
The AO was a result of CAW Resolution Number 1 Series of 2011 citing that the DA Secretary asked the Committee on Animal Welfare (CAW) to review the request of PAWS regarding AO 13 on the use of tambucho (vehicle exhaust fumes) to kill dogs and cats. The Resolution sustained the result of the August 24, 2010 meeting (deletion of tambucho) and invalidated the result of a re-voting on April 12, 2011 which was mainly pushed by Dr. Karlo Gicana of the Philippine Society of Animal Science.
