The outbreak of New World screwworm in the United States brings devastating losses to Mexican ranchers

Mexico's meat industry organization Comecarne estimates that since the United States closed its border to Mexican cattle in 2024, the country has lost nearly $2.8 billion in live cattle export value. The screwworm fly has caused severe damage to Mexico’s livestock industry, with official records showing more than 20,000 cases of cattle infections and 13,000 cases of other animal infections.
