Pork doesn't have to be frozen. I have fed it fresh many times. Parasites are going to be in intestines which you aren't feeding anyway.
Wild boar is another story. Parasites boar into muscles as well as intestines, and while you can freeze it to potentially kill those parasites, the freeze temperature has to be much lower than the average persons freezer. Around -20 degrees.
Tapeworm larvae will be in the flesh of all pork meat if present in the host animal; it's only the adult worms that are in the intestinal tract. Larvae has even been known to burrow into the brains of infected animals. If you're going to raw feed, at least know the risks and don't wave them away when others have a legitimate question.
Pork must be frozen for an extended period (3+ weeks) or cooked before feeding. Humans who eat under-cooked pork meat (not wild boar) are at risk for trichinosis and ingested larvae can cause seizures in humans and animals.
Some of the dietary ideas for humans and dogs circulating around the internet make me believe humanity is going backwards into the caveman era. We've known for millennia that the benefits of cooking food vastly outweighs the risks, and yet, people are disregarding what humanity has understood for thousands of years and feeding a species inappropriate diet to dogs, feeding them like obligate carnivores and omitting the cooked meats and carbohydrates mostly from grains that dogs evolved on and adapted quite well to. Dogs in the care of humans never ate a carbohydrate free raw meat diet, and this is imperative to understanding canine nutrition because dogs evolved to be the species that they are today directly because of that same human intervention and adaptability to an omnivorous diet. Just as humans cannot look to our closest genetic relative and eat like chimpanzees, it is ludicrous to disregard the evolutionary history of dogs and feed them in a way they have not eaten for over 15,000 years, if ever.
