There are dozens, however I'm not sure they'll make any difference to some of you.
My Sophie is destined for an ugly demise after reading some of them, as I'm not as vigilant a mother as some of you, obviously, and don't want to put anything in my baby's hands that could feasibly stop her breathing quite so quickly and easily. My DSis's child had a very near miss with another toy years ago and we could have lost her very easily if we hadn't noticed and reacted quickly. I do think some of these toys should carry specific warnings to parents, and this is one of them.
