ah, I've been getting the same messages from probably the same concerned citizen for months now. Judging by our back and forth he has no experience with high-meat I can tell you that. As a precaution, It might be good to stick with the standard protocol though. It might not be perfect, but at least you have some common ground to troubleshoot from. Honestly I wouldn't in any circumstance keep high meat in plastic (if I am interpreting correctly) and would at least experiment with refrigeration before I messed around with sun and heat exposure. I've left meats in plastic for many days past expiration and do not believe these to be healthy, whereas my 4 month old sludge (in glass/refrigerated) has caused no ill symptoms. I did have some intense reactions around the first times of trying high-meat, which I reported and think brought the concerned citizen to my life. I never even figured out 100% if it was the culprit. Either way, if it gets enough healthy oxygen, I wouldn't worry about it being fatal, although perhaps one cannot label it 100% safe?
