Where do Christians stand on the topic of consuming "unclean" animals?

I am currently ordering a batch of exotic meats from a wholesaler. The meat includes Buffalo, Wild Boar, Kangaroo, Horse, Venison, Zebra, Crocodile, Elk, Ostrich, Reindeer, Frog, Rabbit, Snail, Pigeon, Squirrel, Camel. The problem is that I can't get my mother to agree to eat any of it, as she says that the Bible explicitly prohibits people from eating unclean animals (Deut 14:3-10, Lev 11:3-4).
