“Livestock Brand Commission personnel investigate all agricultural crime in Louisiana including livestock thefts (cattle, equine, hogs, emus, ostriches, turtles, sheep, and exotics), farm machinery and equipment; maintain brand records and publishes a book of brands every 5 years. All enforcement personnel are commissioned by Louisiana State Police and have full police powers in the performance of their duties.”

“Freeze! Drop the turtle!”

They even have a nice PDF to let you register your own brands, and a brand book so you can get ideas.

its not that big these days but there used to be an edible turtle meat industry in Louisiana and the south that canned turtle meat was a real thing … i have a cookbook from the 60s with pictures of the cans for reference …

And the big cattle and sheep states also have various versions of the same thing although i think hanging a thief that was caught red-handed was finally banned
