Purify Food and Water

With this spell the caster makes contaminated food or water pure and safe to eat or drink. Poison is neutralized and spoilage is reversed by this spell. The spell does not protect against future decay, however, nor does it affect magic potions (including, unfortunately, Potions of Poison). Unholy water, if it exists in your campaign, is ruined by the casting of this spell. The spell affects about 2 pounds of food and/or drink per caster level; note that a quart of water or similar drink weighs just over 2 pounds.
