Hmmm. Unless you are just ripping the lard off the animals back, last time I checked trichinosis was the result of undercooking meat.
Also, I should hope that the farmer is using some form of dewormer. There are plenty of proven organic herbal supplements you can give livestock that drastically reduce the parasite load of your average farm animal. I'm using a two-step wormwood-based dewormer and also supplement my animals' diets with garlic powder.
Its a result of diet too. The feed those factory pigs irradiated insanity, which has other debatable negative outcomes, but it does not have the same population of bacteria leading to this kind of infections.
