New World Screwworm Update-
We’re going to try and simplify this…
Unless you are in the yellow zone, you can move livestock as you wish.

If you are traveling with livestock from outside the yellow(infested zone), you may drive through without any paperwork. You will have to tell the checkpoints where you are coming from and where you are going. You can’t not stop in an infested zone for more than a couple hours.
You may take livestock into a yellow zone without paperwork. But they will then be classified the same as the cattle in the yellow zone (infested area).
When you want to take livestock out of the yellow (infested zone)- you will need call Texas Animal Health for an inspection.
(737) 292-9983
They will perform a visual inspection. The cattle must then be treated with Dectomax injectable or Exholt Pour on. Also given an EID Tag. They will then give you a permit to move that livestock 72 hours later. You then have 48 hours after the 72 hours to move them. If you do not get that done, you will need a re inspection(not another treatment if you are within the drug’s efficacy).
If you are sending cows or bulls to market or slaughter, they will perform a visual inspection and release them to those destinations. You will not be required to treat these animals. These animals typically are going to slaughter and there is no medication they can have that won’t have a withdrawal to harvest.
If they do not sell to slaughter- the market will require an inspection by TAHC and a treatment given to them. They can then be released to their destination.
You can move cattle within the yellow (infested zone) without Inspections or treatments. BUT is highly recommended to let them inspect your cattle and verify there are no infected cattle.
Horses- will need to inspected and sprayed by TAHC if leaving an infested zone. If you are going in and out (day working, going to rodeos, etc) they are relying a little more of an honor system. They are trusting you are watching your horses and inspecting regularly. Do not move any horses if there’s any question, call TAHC to inspect them! Lots of vague variables on horses, there’s not many treatment options at this time.
The Blue Additional Surveillance Zone- They request you schedule an inspection on those movements out to help with containment. This area is not restricted and you do not have to treat to come out. Also you won’t need EID tags to move these cattle.
Remember, these are movement restrictions, NOT a quarantine! We can still move livestock and continue business, just need to follow a few protocols!
