Cattle futures rose to their highest in more than three weeks after screwworm was detected in Nuevo León, about 70 miles from the U.S. border. USDA confirmed the northernmost detection of the parasite.
Mexico's Agriculture Ministry said the larvae were in an early phase before becoming flies.
Proximity to the U.S. border raises the risk of further import restrictions, pushing up live and feeder cattle futures on expectations of tighter supplies.
After 148 past bullish disease events, Live Cattle moved a median +0.4% over 5 sessions (62% higher; middle half -0.5% to +1.2%), and +1.4% over 20.
After 122 past bullish disease events, Feeder Cattle moved a median +0.4% over 5 sessions (60% higher; middle half -1.0% to +1.6%), and +2.0% over 20.
