墨西哥牧场主准备在蝇蛆病控制下恢复对美出口

墨西哥北部索诺拉州的牧场主即将恢复对美国的牲畜出口，这标志着因新大陆蝇蛆病疫情引发的为期一年多的进口禁令即将解除。1美国计划从8月24日起在亚利桑那州道格拉斯口岸重启墨西哥牲畜进口，但将实施严格的分阶段控制措施。1根据新规，首周每天仅允许700头牛通关，第二周增至900头，最终逐步提升至1300头。1

禁令期间，墨西哥牧场主收入大幅下滑。1进口禁令前，墨西哥每年向美国出口约120万头牛。1禁令实施期间，国内售价较美国市场低40%，导致行业收入下降40%。1

疫情防控方面已见成效。1墨西哥当前报告1969例活跃蝇蛆病病例，较一年前下降超50%。1该病于2024年11月在墨西哥被首次检测出，目前已传播至该国32个州中的30个。1索诺拉州畜牧工会主席胡安·卡洛斯·奥乔亚表示："我们正处于一个复杂的时刻，需要当局从技术和理性的角度思考，而不是从政治角度。"1

Mexican ranchers in the northern state of Sonora are preparing to resume cattle exports to the United States following a halt that lasted over a year due to New World screwworm concerns.1 The U.S. plans to reopen livestock imports at the Douglas, Arizona border crossing beginning August 24, implementing strict controls to prevent disease spread.1 During the initial week, only 700 cattle per day will be permitted through the checkpoint, gradually increasing to 900 head in the second week and eventually reaching 1,300 head daily.1

The import suspension has significantly impacted Mexican ranchers, with income dropping 40 percent during the ban.1 Before the prohibition, Mexico exported approximately 1.2 million cattle annually to the United States.1 Mexico's livestock export industry generated $1.2 billion in revenue last year.1 Currently, Mexico has 1,969 active screwworm cases, representing a decline of more than 50 percent from a year ago.1 The disease was first detected in Mexico in November 2024 and has since spread to 30 of the country's 32 states.1 During the import suspension, Mexican ranchers were forced to sell at domestic prices roughly 40 percent lower than U.S. market rates.1

Juan Carlos Ochoa, president of the Sonora livestock union, stated: "We are at a complicated moment when we need authorities to think less politically and more technically and reasonably."1 The reopening of the border represents a critical step toward stabilizing the Mexican cattle trade while maintaining safeguards against the spread of screwworm infestation.
