Purport: 

It is the practice that after a snake has been killed, its body is cut into various pieces for fear that it may come to life again simply by interacting with air. Merely killing a serpent is not sufficient; after it is killed, it must be cut to pieces and burned, and then the danger will be over. Pūtanā resembled a great serpent, and therefore the cowherd men took the same precautions by burning her body to ashes.
