Saeed,

Real deal. Actually nothing new, but a couple wet years in a row have blown up feral pig populations, and ground squirrels. Legislators have taken other rodent control methods away, so more diphacinone being used for that reason as well.

I've heard that's possible, but I think it's very localized to the area where the poison is being used (and left available to pigs). This morning I skinned a big boar for a client not terribly far south of that area (same county) in the article. It was very healthy and the fat and meat looked normal (but we don't have a lot of agriculture immediately around our hunting area).

Yeah, it's true.

Misuse of a pesticide is not unusual either. I know that we have had more or less the same problem, with pets, not with pise because Minnesota has no real feral pig populations to speak of. Mainly the problems here are from warfarin based pesticide like Decon.

They have to be wholesale killing off wild rodent populations and the pigs have to be getting into the rodenticide directly to be turning up that kind of blue.

I would guess that with that amount of rodenticide in the pigs that even a hit about anywhere with even a 22 lr would be fatal, though not necessarily quickly. Also, I would expect that the feral cat population and maybe the coyote populations to be declining as a result too.
