Studies have shown that Solanum can still inhabit the body of a terminated zombie for up to forty-eight hours. Exercise extreme care when disposing of undead corpses. The head in particular possesses the most serious hazard, given its concentration of the virus. Never handle an undead corpse without protective clothing. Treat it as you would any toxic, highly lethal material. Cremation is the safest, most effective way of disposal. Despite rumors that a pile of burning corpses will spread Solanum in a cloud of smoking plague, common sense would dicatate that any virus is unable to survive intense heat, to say nothing of an open flame.
