You can pick the worms out of the dog food or just put the dog food at 0°C to kill the worms. This can still be consumed by dogs. As long as not moldy, or worm infestation is not serious, you can eat, after killing the worms, sieve the worm carcass. If the dog food is moldy and hot, or mold is serious, do not consume it. Encapsulated by contamination, or not well preserved by contamination, dog food in many nutrients, in a humid environment is very easy to worm deterioration.
