It'd last however long the food lasted, more or less.
This assumes the zombies are not intelligent enough to take advantage of things like canned goods, but seems to me like once the larger amount of healthy humans to devour were gone (the healthy people learned to stay away from the zombies or government/military forces managed to quarantine the undead), then it would just end up being a matter of time until they turned on and ate each other. Then the problem takes care of itself. Food is everything, especially to a zombie.
