Totally possible, though I always just assumed it was because pork in general carries so many diseases if improperly cooked (as do some sea-fish, hence their prohibition as well) that it's easier to just blanket-ban them than deal with the consequences.
(By the way, reading about how pig-borne diseases killed huge numbers of Indians in de Soto's wake got me wondering if a similar holocaust happened in the Middle East before ancient Israel was established, thus leading to the Judeo-Islamic prohibition of pork...)
