For comparison, last year I was eating a packaged slice of ham and bit something hard, a rock or bone or something. Didn't hurt me or anything, but still odd. It was small and white, but could have been anything. I threw it out.

Later that day I wrote the company just to let them know, thinking if others had similar issues they could investigate.

They wrote me back saying it's impossible their packs would have bones in them, and it's possible my own tooth broke/chipped and that's what I was biting, and attached a coupon for something like 35 cents off one pack.

I found the reply to be really bizarre - I'd probably rather they not responded at all.
