An article recounts the decades-long US effort to eradicate the screwworm, a flesh-eating parasite, using sterilized male flies released via radiation. Weekly aerial drops of 14.7 million sterilized screwworms now form a barrier over the Panama-Colombia border.
Screwworm control keeps cattle movements and exports open; an outbreak would restrict livestock trade and tighten cattle supplies, supporting feeder and live cattle prices.
After 69 past neutral disease events, Live Cattle moved a median -0.1% over 5 sessions (42% higher; middle half -0.8% to +0.6%), and +0.9% over 20.
After 29 past neutral disease events, Feeder Cattle moved a median +0.6% over 5 sessions (62% higher; middle half -1.5% to +2.2%), and +1.0% over 20.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
