Live cattle exports from Mexico to the United States resumed on August 24, 2026, following a suspension of nearly two years. The halt was implemented due to a screwworm outbreak, a parasitic pest that affects warm-blooded animals. The screwworm fly lays its larvae in open wounds, causing tissue to be devoured.

The pest, caused by the Cochliomyia hominivorax fly, arrived in Mexico in November 2024 and is now present in 30 of the country's 32 states. Cases have also been reported in Texas and New Mexico in the US since June 2026. Mexico currently reports 1,937 active screwworm cases. The resumption of trade follows the US approval of a new export protocol.

The new protocol includes the use of radio-frequency identification (RFID) tags in cattle ears and scanners to detect them. Initial cattle crossings into Arizona were limited to 700 head per day, with planned increases in the following weeks. Hundreds of cattle began crossing from Agua Prieta, Sonora, to Douglas, Arizona, after inspections by Mexican and US authorities.

Disagreement on the cause of industry recovery delay

Washington Top News and Associated Press News report that the Trump administration's controls are cited as a factor slowing the recovery of the US cattle industry. They state these controls contributed to the lowest cattle counts in 75 years and a shortfall of about 1.2 million cows, leading to a surge in beef prices.

What the coverage left out

None of the right-rated digests mention the specific number of active screwworm cases in Mexico, which was reported as 1,937 by the left and centre-rated outlets. The right-rated digests do not detail the planned increases in daily cattle crossing limits into Arizona.

Still developing. We have re-checked which outlets are covering this 1 time, most recently on 25 Aug 2026, 01:30, and will add the sides that appear.
