re: Wild hogs chomp and stomp their way through $90 million worth of Louisiana crops

I read an article several years ago about an Alabama university developed a "poison" for hogs that was not harmful to anything else. I think it was a salt/sodium based stuff the pigs liver could not metabolize. It was super cheap and 100% effective. Pig basically went to sleep and never woke up.

Never heard about it again. My guess is it was too effective? Anyone else recall this?
