I'm not 100% certain,(tissue!! Cut-up!!)but I'm gonna go for it, anyway:

1. Cysticercosis
2. Taenia solium
3. Ingestion of undercooked pork

I largely agree with Heather, although I too am not at all certain. If it is T. solium, my guess would be that this form of the disease probably results more often from ingestion of eggs via fecally contaminated food. Don't know what the extent autoinfection (i.e. ingestion of infected & undercooked pork - taeniasis - retrograde transit of gravid proglottid - oncosphere mucosal penetration - intermediate host sequalae) may be???
