In the Fall, we bought a bag of fish food. Some of it appeared to have mold, so we didn't use it. What's the best way to discard it? I didn't know if it would harm wildlife if we just threw it in the trash can and it was taken to the dump. Would it be better to bury it? I think it was a 25 lb bag. It wasn't convenient to return to the store and wasn't the expensive feed. Thanks in advance for any suggestions.
