Yeah, I'm guessing being Costco, they are marketing this to the average 2.5 kids and a dog family. Being dehydrated, once it's opened, just like oatmeal or similar, if you put a lid on it and store in a cool, dry place it should easily last half a year after opening. A fifty serving container would give four people twelve meals (12.5 actually, but the dog's gotta eat too :) ), so it wouldn't be sitting around too long anyway. Might be more problematic for just one person.
