Im bringing Pork Beef Buns but for you I can bring some mini-matzo balls and gefilte fish. I'll get the local Rebbe who is Shochet to bring brisket for the BBQ.

Because at that time pork had the risk of trichinosis. So no longer applies (in reasonably clean areas). That is true but is only one of many reasons why pork is forbidden

Some of my notes:
pig principles: environment, not very mobile dont need big pastures like cattle or sheep ideal for raising in a settlement or city eat human trash but makes them poorly suited for pastoral and nomadic lifestyles, society, pig husbandry in cities is often associated with lower socio economic status, settlement, pigs are useful for people to settle a new area since they can reproduce quickly new herds can be established quickly with just a few starter animals, economy, pigs can be harder to regulate than other domesticated animals for two reasons their litter sizes can vary drastically 12 - 14 piglets but usually much less they dont produce secondary products like wool or milk which are also valuable sources of taxes and institutional wealth in pre industrial societies so governments encourage raising other animals like goats sheep cows, health, pigs carry disease and are susceptible to parasites like tape worms that can be transmitted to humans. pigs only take a year to mature and eat your trash.
