USDA reports one active screwworm case remaining out of 48 confirmed US animal cases as of September 8. USDA's Economic Research Service left its 2026 beef and veal price forecast at +9.8% on August 25.
Contained disease levels support reopening trade, but the unchanged beef price forecast shows that tight cattle herd numbers, not screwworm, drive prices higher.
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.
