Active US screwworm cases rose to 65 in the week to Nov. 11, more than triple the 21 reported on Oct.
19. New Mexico reported 40 confirmed cases, Texas 23 active cases and Arizona six, and a Wyoming beef company questioned whether recently imported Mexican cattle caused the rise.
Rising cases could lead to movement restrictions and tighter cattle supply, supporting live cattle prices. Renewed concern over Mexican cattle imports could also delay reopening of the border to feeder supply.
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.
