USDA data show more than 40 New World screwworm cases confirmed so far in November, the worst month since the pest first appeared in Texas earlier this year. Total animal cases reached 128, with 65 currently active, and the most recent detection was a horse in Otero County, New Mexico.
Rising screwworm cases raise concern over US cattle movements and feeder cattle imports from Mexico, adding supply uncertainty to an already tight cattle herd and supporting live and feeder cattle prices.
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.
