https://www.sfgate.com/central...firefox-newtab-en-us Is this just a California thing, or has this occurred in Texas, Florida, etc. I've never found any of the hogs I've shot with this indicator.

Interesting.

I had read the "blue meat" dye was a way to get poisoning for pigs approved. It was not so much the meat but the fat where the dye would accumulate. They were hoping that you would notice the blue fat before you ate the pork and died your self!

I have read the same thing as Live Oak--dye is a way to separate potentially harmful meat from good meat.

The poison is named “Kaput”, and it works. It also is supposed to leave blue indicator in meat as indicator pig was poisoned. Story and photo link below.

Horrors.

It doesn't always leave the blue coloring -- or at least not right away.

Poisoning this way is wreckless.

"Fish and Wildlife’s Wildlife Health Laboratory is advising hunters to not consume meat from any animals showing discoloration. Visible signs aren’t always reliable, however. “As demonstrated by findings of exposure in nongame animals, the discoloration is not always present and is not a reliable indicator of AR [anticoagulant rodenticide] residues in meat,” the 2018 study said."
