This has nothing to do with Unvc, but just something to chew on. My neighbor is the local funeral home owner. He claims they use, it was either 1/4 or a 1/3 less preservatives in the embalming fluid as they used to. Due to all of the preservatives we eat in our food.
We have a local bakery, which is phenomenal. The bread you buy there, goes bad in 3-4days, because of no preservatives. Store bought, lasts 2-3weeks. If you are really concerned with your health, just something to think about. I can't back up my neighbors words, so take this for what it's worth. Go Unvc and Glta!
