To the best of my understanding, gluten is a protein composite found in foods processed from wheat.  I am emphasizing 'wheat' because I have a question about this.

I was in the supermarket yesterday. While walking through the Meat Dept., I noticed in the refigerated shelves they had packaged sliced ham listed as "gluten-free".  Yeah, last time I looked, pretty much all pork products didn't come from wheat.

So, I guess I'm wondering why any non-wheat product like pork, beef, etc, etc, that is obviously not  a wheat product be listed as 'gluten-free'.

Can someone please exzplain this? Thanks in advance. :)
