You should only cold smoke cured meat. I'm originally from Lumberton,NC I learned how to cure and cold smoke from my dad and grandpa. If you want to cure and cold smoke leaving it in the smoke house then there are some things you got to know. For instance a Ham or shoulder. You will have to use enough curing salt until the meat is hard. If you can press(with your finger) it making a dimple then it not enough cure. This is what we call "Country Ham". You will have to soak it before cooking it as the salt content is very high. You'll have to smoke it about two weeks(that was our rule anyway)... remember these old timers were preserving meat that would last years. The next thing is making a paste to protect the meat from (skippers) this is a tiny fly which will lay eggs in your meat, then it will have worms. So, we used brown sugar, black pepper and borax (not even sure if you can buy borax anymore) ... but you can do without it. Black pepper, red pepper and brown sugar boiling it all together until thick. Coating the meat and top it off with black pepper at a 1/8in thick. This will protect the ham. I know what the summers are like around the Piedmont... It does get pretty hot... When I say smoke house, I talking about a real smoke house that during summer temperatures the inside temp is at least 72 degrees. Now, If you can do all that, then your hams will keep as long as 7 years. This is funny cause who could let a nice country ham hang for 7 years? Thats exactly right no one! but it would keep if needed.
We did it this way on the farm because we had big families and had to produce our own meats. It was just our way of life. It's good to know how to preserve meat in this way, but not a must such as it was with us. I cure and cold smoke hams, shoulders, bacon and fatback, pork loins but none of it last long enough to go bad, so I always try to use the minimum curing salts. In the summer months I hang the meat in the keller (cellar) which is about 72 degrees. If I can be of anymore help let me know.... Happy smoking
