Mexico's agriculture authorities and cattle groups in Sinaloa have launched a preventive plan against screwworm to protect more than one million head in municipalities including Guasave, Mocorito and Mazatlán. Sterile fly dispersal in the state is due to begin in January.
Cattle groups also rejected a request from industry to raise the duty-free beef import quota to 150,000 tonnes for 2027, while the price of live calves has fallen 13.3%.
A larger duty-free beef import quota would add supply to Mexico's market and pressure domestic live cattle prices, which are already falling. The screwworm threat adds risk to herd health and therefore to supply.
After 70 past bearish disease events, Live Cattle moved a median +0.0% over 5 sessions (51% higher; middle half -1.7% to +1.0%), and +0.4% over 20.
