Why Mexican Avocado Shipments to the Us Were Suddenly Halted Again
American consumers often assume border agricultural screening occurs entirely at commercial land ports like Laredo or Pharr. For Mexican avocados, the critical screening occurs hundreds of miles south inside the orchards. Under longstanding bilateral agreements designed to shield domestic American crops from invasive pests, such as the avocado seed weevil and fruit fly, every export orchard and packinghouse must undergo rigorous pre-clearance.
APHIS inspectors verify that orchards meet sanitary standards, fruit is pest-free, and harvesting crews handle produce strictly according to protocol. If an inspector is not physically present to witness the boxing and apply the official seal, the fruit cannot legally enter the United States.
This requirement gives Washington immense, immediate leverage over the supply chain. The moment inspectors pull back due to a security alert, the export pipeline dries up instantly. Michoacán producers cannot simply divert uncleared trucks to the border and hope for inspection at Texas entry points. Without the origin stamp from APHIS personnel, shipments are turned away at the international boundary.
