USDA Reopens Border to 700 Mexican Cattle a Day as Screwworm Fears Split Ranchers

3 articles · Updated · CNN · Aug 22

Summary

  • Douglas, Arizona, will reopen on Aug. 24 for Mexican livestock, with imports initially capped at 700 cattle a day under RFID tracking, inspections and chemical dipping despite a new screwworm case in Sonora.
  • USDA says Sonora’s controls and the lack of broader infestations justify moving ahead, while reserving the right to halt reopenings if the pest threatens the U.S. herd.
  • U.S. ranchers are split because record cattle prices have boosted their income, but the administration is under pressure to ease beef costs before the 2026 midterms; industry groups say more imports could depress domestic prices.
  • Mexican producers say the closure cost them up to $1,000 per animal and pushed more cattle into Mexico’s own supply chain, helping lift boxed beef exports to the U.S. by 22% and straining American meatpackers.
