That's most likely it, but the bible doesn't go ahead and say "don't eat pigs." It says that as far as mammals go, we may only eat those which have split hooves and chew the cud. I don't know what chew the cud means, but pigs don't do it. Camels' hooves are only partially split.
Mammals: Leviticus 11:3 (Also, for cannibalism, Numbers 19:11 can be applied.)
Birds: doves, pigeons, and quails (they are allowed as sacrifices). Chickens, turkey, etc, are in the quail family, I guess. But ducks and such things are not allowed. Carnivorous birds are also not allowed. Eggs follow the rules of this.
Seafood: Leviticus 11:10 (And all that have not fins and scales in the seas, and in the rivers, of all that move in the waters, and of any living thing which is in the waters, they shall be an abomination unto you.)
Insects: Leviticus 11:20 (Even these of them ye may eat; the locust after his kind, and the bald locust after his kind, and the beetle after his kind, and the grasshopper after his kind.)
Blood/fat: Leviticus 3:17 (It shall be a perpetual statute for your generations throughout all your dwellings, that ye eat neither fat nor blood.)
Already dead animals: Leviticus 22:8 (That which dieth of itself, or is torn with beasts, he shall not eat to defile himself therewith: I am the LORD.)
