Srimad Bhagavatam Canto 10, Chapter 06, Text 33

SB 10.6.33

kalevaram parasubhis
chittva tat te vrajaukasah
dure ksiptvavayavaso
nyadahan kastha-vestitam
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
 
The inhabitants of Vraja cut the gigantic body of Putana into pieces with the help of axes. Then they threw the pieces far away, covered them with wood and burned them to ashes.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
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. Putana resembled a great serpent, and therefore the cowherd men took the same precautions by burning her body to ashes.
