According to Haitian voodoo, there are several precautions people can take so that their deceased loved one can avoid being turned into a zombie:
1) Bury the body under heavy stones so they are harder to dig up.
2) Watch over the grave for 36 hours (after 36 hours, death is final and a bokor can no longer turn a dead body into a zombie).
3) Cut the head off the body.
Beware at ground zero, as Zombies have been known to "rise to the occasion" when visited.
