Screwworm Crisis Hits Global Livestock Markets: Panama Canal Panic and Beef Supply Chains on the Brink
A silent biological invasion is rattling global supply chains as the New World screwworm—a flesh-eating pest—spreads across Central America, triggering emergency livestock quarantines and threatening a collapse in beef exports from the region. Panama has deployed 200 million sterile flies per week in a desperate containment effort, but farmers from Costa Rica to Texas are on high alert: infected cattle can die within days if untreated. With the pest now identified in previously clean zones, logistics giants are rerouting livestock shipments away from the Panama Canal corridor, raising costs by 15 percent overnight. CEOs of food conglomerates are quietly hedging against a potential price spike, as the screwworm outbreak underscores the vulnerability of just-in-time meat supply to microscopic threats. The bottom line: this is not a biology problem—it is a boardroom liquidity risk.
