Anything that was in effect is pretty much STILL in effect if not more. The whole of coastal Cameron Co is quarantined and licks of it now extend out as far as Rio Hondo and up FM 1420 into Willacy Co. The line as it stands now is some pastures East of 1420 are in but not every pastures up to FM 186. No ticks have been found along 186, but because of logistics some pastures are quarantined. If a tick is found, that pasture is quarantined, as are ADJACENT pastures. There are 5,000-8,000 ac pastures along the coast, or bigger; so it's become an unbelievable burden on a couple, if not one, large ranch. There's some cattle out there that deeply resent being worked 1x/yr & being on a 30-50 dipping day schedule is an insane pace that has been extremely hampered by the wet 2015.
Then there is the permanent zone along the Rio Grande river (Hidalgo/Starr) and actually parts of eastern Kleberg Co, I believe south of Vottman. That tick was traced, IIRC, from a Caneron Co cow that sold at Three Rivers last year.
TL;dr- it's not any better yet.
