The hog farm issue you mention, if I remember right, is that you cannot brings hogs from Mexico, alive or in meat form, because of a disease the Mexican hogs have that is fatal to hogs, not people. I have personally been busted when returning from Mexico by the USDA people at the Houston airport for bringing in chorizo, which is a well cooked, preserved sausage sort of like salami, which cannot be imported despite the fact that it is cured. They confiscated my chorizo, huge bummer.
That does suck, but the farm issue here is where to put it. They want to move a 52,000 + hog farm into these areas, and the environmentalists are losing it. They say it will hurt the area. OMG, this is the freaking desert, there is nothing here to hurt. The AG businesses around here want the farm for the cheap fertilizer, but the greenies are pitching a fit. I am trying to find a link I can use for the articles I have read. But this is a Imperial Valley issue here in AZ/CA. I'm sure it isn't something the Washington paper is interested in. It just seemed so coincidental to me.
wha about feral pigs? are they prevented from crossing
