It won't go bad.. You are supposed to keep in the fridge so it stays fresh and you keep the contents vital longer over the life of the bag. Having it out for the day is not going to do any damage to it. Its not going to turn or go bad, its like storing your vitimins in a cool dark place, its just to keep them fresh! The flax seed, in oil form can go rancid if it gets warm, so be careful not to leave it out in higher temps or outside in the sun, for any of us who feed it to our larger dogs who might eat on the porch.? The Missing Link formula does contain flax but its not heavy in oil so I would not be overly concerned by it. If it was rancid, YOU"D KNOW! Its not a nice smell! lol
