Oh for heaven's sake. It was economics, politics and, to an extent, aesthetics.
Pigs don't graze and they can't be herded about like sheep or goats. They must be kept in pens.
Unlike grazers, they must be fed the same food people eat.
They cannot be ridden, they can't pull a plow. They don't lay eggs. They can't change grass to milk or wool.
They originated as northern European forest animals. They don't do well in hot climates. In hot climates they need lots of water -- a scarce resource -- plus mud to wallow in and shield their skin from the sun.
Confined in pens, the normally clean animals have no choice but to relieve themselves where they live, sleep and eat, soiling themselves, creating a massive stench, polluting water sources and generally being a public nuisance.
And they make rude sounds.
Thus pork was an expensive indulgence of the rich and a health hazard and annoyance to the general community. Naturally pig farms were resented and the pigs regarded as unclean. When they could, communities banned pork production.
The trichinosis theory is dubious, as the cysts weren't discovered till 1821, weren't recognized as pathologic for some years after and the route of transmission by undercooked pork not established till the 1860s
I've also read that in the ancient middle East you were more at risk of contracting diseases like brucellosis, listeriosis or campylobacteriosis from beef and poultry than trichinosis from pork.
