It is illegal to poison hogs and other animals in Texas. There was a big problem in Eastland County last year (2009).

*Exception for targeted rodents and such.
Yes, exactly because of the reasons I noted above and that were also mentioned in the link you provided. It’s near impossible to target poison the wild hog.
I did not know about the specific incident mentioned in the link, but our place is in Stephens County and I was all over Eastland county attending colleges there. And hearing the part about peanut farming sounds right since that’s a fairly big thing down there. They have the soil for it.
