The old "jello has horses' hooves" story has been around forever. Interesting that the version current among Moslems is that it has pigmeat in it ~ not that there's anything wrong with pigmeat ~ pigmeat is good for you in fact, God's own gift to hungry mankind.
Lev 11:7 And the swine, though he divide the hoof, and be cloven-footed, yet he cheweth not the cud; he is unclean to you.
