The verse in Leviticus 11:43 speaks about becoming unclean by eating "unclean" animals.
You shall not make yourselves abominable with any creeping creature that creeps, and you shall not defile yourselves with them, that you should become unclean through them.
How can one who ate unclean animal can get cleansed/purified from that eating (the eating itself, I am not talking about the uncleanness that comes by touching)? Will he be forever unclean?
Does this type of uncleanness prohibit him from eating sacrifices or entering the temple?
