What is this yellow "fat" thing on my bacon Searching in google for yellow bacon fat returns nothing

I'm assuming it's fat, but have never seen a large yellow lump of it on any bacon I have had in the past.

Would this still be good to eat? (Already ate half the pack...)
That's a piece of the rind of the bacon, which is yellow because it was exposed to the smoke. The bacon shifted while being sliced, causing the strip to end up attached to that one piece rather than in bits on the others. It's fine to eat.
