AUSTIN, Texas - Texas agriculture officials are imposing stricter movement requirements on certain Mexican-origin cattle entering the state as New World Screwworm continues to spread in Mexico.

What we know: The Texas Animal Health Commission (TAHC) issued an emergency order on Monday requiring cattle of Mexican origin to have additional identification and health documentation before entering Texas, even if they first enter the United States through a port outside Texas.

Dig deeper: Under the new requirements, affected cattle must have an official radio frequency identification device (RFID), an electronic certificate of veterinary inspection (eCVI) and a Texas entry permit.
