Happened to me this year too. I threw out two packs that were in the door (stuck a temp probe in the meat and didn't like what i saw). Anyway, we refroze everything and have been eating it ever since. Deer, turkey, bear. I have an alarm but the damn thing had been silenced for some reason. I also have a thing plugged into the outlet that will constantly beep if that circuit trips. While on vacation, I'll live stream the garage camera at least once a day to see if I hear the beeping noise indicating a breaker tripped for some reason. Last summer it had tripped and I called a buddy to reset it.
