On serious side, most pork and poultry has parasites which is why they say to fully cook that. Most wild game has parasites, most microscopic that you do not see and usually in the organs. They defecate and urinate over the same areas they eat and that transfers eggs from animal to animal. Tapeworm survives from winter to winter so freezing obviously does not kill 100% and when weather warms up areas where they are mostly eradicated end up reinfected through predators, livestock and other sources. It does kill most of it to take the infection rate below the FDA "safe limits" but the eggs can go dormant and survive freezing which is the purpose of cysts. Keep in mind that most freezers are not at zero degrees or below. For freezing to be effective, experts suggest -4 degrees for at least 10 days followed by fully cooking the meat.
Organ meat (heart/liver) especially in areas where game meat with cysts on the organs are found should be froze at less than zero degrees for at least 10 days and cooked to an internal temp of 145 which is well done. Most of the time this is enough.
In the end, that meat is probably safe to consume if you trim the cysts off along with surrounding meat. Not really appetizing though. I used to see ring worm all the time when I was butchering domestic rabbits on the farm and just trimmed the infected area off. Another reason I wear disposable gloves handling raw meat and wash hands regularly.
