I do not know of any catfish species that have poisonous whiskers. The whiskers are for feeling and tasting stuff on the bottom of the lake, pond or ocean. However, most catfish do have spines on dorsal (top) and side fins. It is possible to hold a catfish without getting stabbed by one of these sharp fins. If a catfish does happen to fin you and break skin, make sure you wash the wound thoroughly, especially if the catfish was a freshwater variety. If it is a saltwater catfish and you get finned by one, though it may hurt, wash your wound with ocean water.
If the wound from a fin is deep, go to the ER and have them take a look to make sure the catfish did not injure any important parts of your body.
Catfish whiskers are called barbels.

Barbels

Although catfish have what looks like whiskers, they are actually barbels. The barbells have taste receptors on them, so a catfish can find food in it's natural, murky habitat.
