Mexico’s Ministry of Agriculture announced the suspension of most live animal imports from the United States following the confirmation of New World screwworm cases — a dangerous flesh-eating fly whose larvae infest and feed on the living tissue of animals.
The measure applies to imports of cattle, horses, pigs, sheep, goats, and other animal species. According to the ministry, the decision was taken in coordination with the United States Department of Agriculture (USDA).
Mexican authorities stated that the restrictions are intended to protect livestock production in the country’s northern states, including Baja California, Baja California Sur, Chihuahua, and Sinaloa, where no cases of the parasite have been detected so far.
The New World screwworm remains a significant concern in Mexico. Since November 2024, more than 28,200 cases of infestation have been recorded in the country.
In contrast, the first confirmed cases in the United States were reported only recently. According to U.S. authorities, five cases have been detected in Texas and New Mexico since June 3, 2026.
The New World screwworm is considered one of the most harmful parasites affecting livestock. Female flies lay eggs in open wounds, and the larvae subsequently feed on living tissue, causing severe injuries, reduced productivity, and, in some cases, death.
Mexican officials emphasized that the restrictions are precautionary and aimed at preventing the parasite from spreading into regions that currently remain free of the disease.
