The advantages of organic for produce are anywhere between dubious or marginal. I would have said there's it's better with animal products, but that's largely owing to the overlap with free range / grass-fed. I don't really care if the grain they happen to eat is also "organic".

In conventional farming conditions are so bad for pork that a large percentage of them die of disease, despite all the anti-biotics, before even heading to the butcher. I feel less inclined to touch that stuff unless it's from a local farm I know. Poultry and beef have their own set of problems.
