This is what happen if you consume pork. It does not matter if the pork is a 'good' or 'bad' pork. There's parasites in pork meat.
It is created as such. Pigs eat their own wastes. The parasites that in pork can never be kill even the heating it to the highest degree of heat or froze it to the lowest degree of coldness.
And on top of that Allah says that in Quran. So, am a muslim who will not consume pork just because it is proven 'dirty.
