I've had very little problem with hog meat, except right on the immediate coastline of GA. The pigs there live in the tidal grass and feed in the salt creeks, digging for the little tiny crabs especially.
That mud has the most awful smell to it at low tide, and the pig meat smells JUST LIKE THAT mud when you cook it!!!! I won't even go down there to shoot pigs any more because of that.
As to big boars- I have had a couple pretty rank ones that were only fit for sausage but for teh most part I've never felt the meat was tainted to the ponit we couldnt use it- so far! Again, my hunting is limited in range...just SE GA and Southern South Carolina.
There's no doubt, though, that if you want to cook and eat a pig then take a herd pig, between 75 and 125 lbs and you won't find any better eating on the planet.
Shoot a big boar to get a trophy would be my advice.
I'll pass on the recipe we use if anyone is interested?
