If I find any ground hugging snake on my land (i.e. garter, black, indigo, pigmy-timber-diamond rattler, red-yellow rat, coral, etc.), then I know I have no hogs. Hog noses can locate the snake musk, which they eradicate like cotton candy. There were times when I was concerned about driving my equipment in fields as the many irregular holes they dig while rooting for food could easily break a tractor axle. I shoot them in the head and they are DRT.
The meat in a 200# pig that has eaten a smidgen of whole kernel corn (yeah I know that is encouraging them) over about a 2 week period loses the grey mesentery in its viscera, which is replaced by a thin yellow layer of fat, and the meat is quite good to eat - provided you drop them in their tracks. Hogs straight off of the flood plain, meh, the meat isn't as good, with a sort of muddy taste since they eat a lot of dirt, but is still edible. I would have deer if there were no pigs, coyotes, bear, cougars, or poachers. In the meantime, I'll take what I can get and I have passed on pigs while hunting deer.
Like habitat, food conditions vary greatly. Here there is abundant omnivore food and a rich and diverse riverine habitat. TX, IDK, but certainly a different habitat and food source, so the meat will vary. None here EVER found with worms, sores, or diseased (by eye - microscopic notwithstanding).
After 30+ years of hunting them on small acreage, and eating them, I'm still standing!
