I assume it does not. I have a kit I bought 5-6 years ago, but never used it. It contains 1 oz of cure, which I assume is still safe to use. Correct?
1. It is hard to kill salt.
2. Does it have an expiration date??
If not I would use it unless it was opened and somehow contaminated..
Yea...that was kinda my thoughts as well. No expiration date...
