Ouch. Hopefully not too much of a stinking mess. I saw a cool analog method of doing spot checks to guard against thaw and refreeze events that happen without your knowledge, which could be bad. Fill a 2 L soda bottle 1/3 of the way with water. Freeze it upright. Fill the rest with gravel. Cap it. Place upside down in freezer. Check periodically to see if the ice is still in place or if it has thawed and run into the gravel and refroze. Doesn’t help for total unit failure which would be obvious, but could give you a hint in other circumstances that the goods got sufficiently warm at some point that they should be suspect.
