A healthy board shouldn't be wormy. The worms are an indication that the animal isn't healthy. Parasites shouldn't be harmful as long as you cook the mest properly, but yeah I can't say I'd be too interested in eating if I found a liver full of worms. I had always heard that raising any pigs on pasture would lead to very wormy pigs as well, especially in the southern US. We raised a pair of pigs on pasture last year and when we butchered them we found absolutely no parasites or signs of previous infection. They were pastured, fed extremely high quality food, but otherwise never medicated or vaccinated. We did feed them plenty of squash seeds when squash was in season, those work great for helping with parasites load. Purely anecdotal, but I absolutely believe that a wormy animal is a sick animal. I have to assume most people raising pigs on pasture have them on pastures that have been sprayed with pesticides and/herbicides and chemical fertilizers, and likely feed a high grain diet of GMO'd feed that was sprayed with glyphosate during harvest.
