美国-墨西哥对新世界螺旋藻的边界封锁切断了墨西哥牛的进口,加剧了历史性的牛肉短缺,并迫使大片饲料点关闭。 A U.S.-Mexico border closure over New World Screwworm has cut Mexican cattle imports, worsening a historic beef shortage and forcing major feedlot shutdowns.

美国-墨西哥边界因新世界螺旋虫而长期关闭,严重扰乱了牛肉业,切断了墨西哥饲料牛进口,并加剧了历史上牛的短缺。 A prolonged U.S.-Mexico border closure due to New World Screwworm has severely disrupted the beef industry, cutting off Mexican feeder cattle imports and worsening a historic shortage of cattle. 美国农业部数据显示, 料库存处于75年来的最低水平, USDA data shows feedlot inventories at a 75-year low, with placements down 5% in January. 封锁始于2024年,已迫使德克萨斯州50 000头主要饲料区Lubbock饲料厂关闭,70年后对当地经济和供应链产生影响。 The closure, initiated in 2024, has forced the shutdown of Lubbock Feeders, a major 50,000-head feedlot in Texas, after 70 years, impacting local economies and supply chains. 牛的高价格、销售的减少和牛群规模的减少继续给生产带来压力,工业领导人警告说,牛肉产量损失高达10亿磅。 High cattle prices, reduced marketings, and declining herd sizes continue to strain production, with industry leaders warning of up to one billion pounds in lost beef output. 严格的生物安保措施防止了螺丝虫的传播,但危机凸显了美国牛肉供应链中持续存在的脆弱性。 Strict biosecurity measures have prevented screwworm spread, but the crisis highlights ongoing vulnerabilities in the U.S. beef supply chain.
