It isn't a treifa but it's still prohibited on account of sakana 
(Yoreh Deah 60:2).
That we don't add to the list of 70 treifot is in the Rambam Hilchot 
Shechita 10:12.
There is a machkloket whether the 70 treifot are halacha l'Moshe mi'Sinai (Pri
Megadim) or based on svara of Chazal on the general 8 categories (and 18
sub-categories) of treifot (Kreiti u'Pleiti).
