Actually, that got changed in the NT. V will be able to tell you where specifically but it's no longer bad.

(side note: back in the days of really poor sanitation... most of the things prohibited in the OT could get you really sick if not prepared right. This may have been more of a 'don't eat this shit... seriously' than a 'you're going to hell if you do')

That and a set-up for the arrival of Christ (but don't tell the Jews!)
