USDA has confirmed 99 New World screwworm animal cases in Texas, New Mexico and Arizona since June, including nine new infestations since Monday. Of these, 42 cases are active, and detections rose sharply in October after a quiet August and September.
A rapidly growing screwworm outbreak in US cattle country raises risk of movement restrictions and herd losses, which could tighten cattle supply and support live and feeder cattle prices.
