This spell has the same effect as prevent spoilage, but in a much larger area of effect with an increased duration. In addition to that it also prevents food from being spoiled even if it is dropped into a sewer - if it is washed or rubbed off even slightly, the filth will be removed and the food will be as good as it had been at the day of the spell casting. Obviously, if it is cast on already rotten food, it will not change its quality into good, but it will prevent further decomposition. Both prevent spoilage spells may be applied to easily decaying plant (or even mineral) poisons - if they are treated with this spell they will be untarnished by time. Once this spell runs out, the previously protected material will start to decay at its normal pace again.
The material components are the holy symbol of the priest and a piece of a grain storage sack which has somehow survived over one hundred years without magical prevention of its decomposition.
