I looked at the ingredients & nothing looked "foreign". At my ex-job they would sometimes get in the fake cheese, but it had a lot of wax in it & that wasn't listed.
Besides, at least wax would've melted!
I ended up shredding string cheese! lol, not an easy task...oh, and I got my shredder there, too. As well as 3 packs of good white socks for my DD, that's a good deal.
