Couldn’t say about the precooked stuff.
If the ingredients list any nitrates, I’d avoid it because I don’t know how it was cooked.
That said, I wouldn’t eat it all that often. So, to have it just once in a while, I wouldn’t worry about it.
Uncured is fine in this context. It lacks the chemicals of concern.
But it’s technically not bacon. It’s pork belly.
So, depending on how you cook it, it’s no more risk than that of a pork chop.
And pork belly is also awesome, by the way.
My wife brought home a big butcher pack yesterday.
