We were in NYC where I am pretty sure many of the kisses varieties we previously had used had a "manufactured on same equipment as almond" or similar. I know for sure the caramel ones are no longer labelled safely for us, and we use to be able to get them all the time. Pretty sure the cookies and creme ones did too. But I think it is a recent shift and other packages are still around.
FWIW, my dd is PA and TNA, and we have never avoided shea. Not saying anyone should or not, but just that there are varied comfort levels with it. It was never mentioned to us, and seem to crop up after some years of her being diagnosed(the shea discussion).
