The USDA has issued a warning to Mexico, threatening to halt imports of live animals such as cattle and bison if immediate action is not taken to combat the spread of the New World screwworm, a dangerous pest spreading northwards. Agriculture Secretary Brooke Rollins has given Mexico until April 30 to address this crisis, as the USDA's sterile insect technique program to control the pest faces operational challenges due to restrictions from Mexican aviation authorities. The situation is further complicated by Mexican customs imposing high import duties on necessary supplies, which are funded by U.S. taxpayers. Rollins is calling for immediate operational clearance for Dynamic Aviation, waivers on duties for emergency materials, and the appointment of a liaison to expedite solutions. The USDA stresses the urgency, warning that continued delays could severely impact American agriculture and has proposed an emergency U.S.-Mexico summit to resolve the issue swiftly.

The USDA, led by Secretary Brooke Rollins, has warned Mexico that it will stop imports of live animals if the New World screwworm issue is not addressed by April 30, highlighting the urgency of the situation.

The New World screwworm is a flesh-eating fly that threatens livestock by spreading rapidly from Central America to southern Mexico, posing a significant threat to the U.S. cattle industry.

The USDA's sterile insect technique (SIT) program, which relies on aerial dispersal of sterile flies, is being hindered by Mexican aviation authorities limiting operations to six days a week.

Compounding the issue, Mexican customs are imposing hefty import duties on critical supplies needed to combat the screwworm, despite these being funded by U.S. taxpayers for the benefit of both nations.

Secretary Rollins demands Mexico provide long-term operational clearance for Dynamic Aviation, waive duties on emergency materials, and appoint a senior-level liaison to fast-track solutions.

The USDA warns that each day of inaction gives the screwworm a stronger foothold, risking devastation to American ranchers and the broader agricultural economy.

An emergency summit between U.S. and Mexican officials, alongside technical experts and operational partners, has been proposed to address and resolve the crisis effectively.
