Some are. But many will only cause injury with their hollow barbed fins, which can deliver a stinging protein. But some species, such as the striped eel catfish, can deliver a toxic mucus that may be fatal to humans. The edible portions of catfish do not contain any toxins.
A recent study suggests that about half of the 3000 known species of catfish are poisonous. Only a few species are poisonous enough to hurt humans (none in North America). The rest cause about the same amount of discomfort as bee stings. National Geographic also states that as the catfish grow, the venom glands shrink, indicating the venom glands are meant for defense while the fish is young.
The venom comes from glands near the pectoral fins. When the fins are grabbed the glands are ripped, releasing the venom.
The majority of catfish species have poisonous barbs located within their dorsal (top) and lateral (side) fins. If stuck with one of these, they can inject a toxin which causes a painful sting which usually resolves on its own after time. However, like any wound, it can get infected and it is advisable to clean and treat it. Only a select few of catfish species (located in areas of Southern Asia and India) have stings which could cause serious complications, or very rarely, death.
The catfish toxin is protein-based (like bee stings) and thus is treatable with meat tenderizer. Ammonia and vinegar will not be very effective, as they are alkali (base) treatments, to be used for acid-based toxins.

Are catfish whiskers poison?
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.
Is anything poisonous about catfish?
No, but they can inflict a wound that can become enflamed or infected. If you are ever finned by a catfish, make sure to clean the wound. If you are fishing in the ocean, use ocean water as a temporary cleaner. When you get home clean the wound. If you are fishing in fresh water, try to clean it with bottled water temporarily until you can get home to clean it properly. If you get finned so badly that the bleeding won't stop. Go to the nearest Emergency Room. The fin might have hit a blood vessel.
