The Arizona Department of Agriculture confirmed the state's first New World screwworm case, found in a ranch dog in Cochise County. Local ranchers are on alert over the parasite's potential impact on livestock and the cattle industry.
A screwworm presence in Arizona, a cattle-producing state, raises the risk of livestock losses and movement restrictions, which could tighten feeder and live cattle supply. Any spread into herds would be bullish for cattle prices, though this single dog case is a limited early signal.
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.
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.
