A dangerous, flesh-eating parasite is prompting changes to import rules. The goal is to protect livestock from this threat. Tighter requirements are being implemented for cattle originating from Mexico.

This move aims to safeguard state livestock from the parasite, known as New World screwworm. Further information on these new import rules and the parasite is available from the source. Details on the specific requirements and their implementation have not been outlined here, but the change is intended to address the spread of the parasite.
