“quantities of intercepted bologna are so large that it’s hard to believe that there are any pigs left in the world”
There you’ve kinda glanced off the actual issue. Factory farming increases the likelihood of zoonotic illnesses, and more animal-friendly forms of animal husbandry are too big of a burden on the environment (assuming the same production volume). The only solution is to drastically lower meat consumption.
Obviously they’ll get more sophisticated in their future meat smuggling endeavors - changing form, packaging, etc. I for one welcome our bologna fry overlords.
