Starting August 3, 2026, travelers bringing dogs or pet birds into Mexico must obtain a New World Screwworm Inspection certificate. This new requirement is tied to a serious parasitic threat that could devastate livestock and wildlife. The certificate is issued by a USDA-accredited veterinarian within five days of travel and must prove the pet is free of screwworm infestation.
The adult screwworm fly lays eggs in open wounds, and the resulting larvae burrow into flesh, causing severe damage and potentially death. Mexico had previously eradicated screwworm through sterile insect release programs, but the parasite has recently reappeared in the region, raising concerns about its spread through animal movement.
This new regulation aims to prevent the introduction of this destructive pest and protect Mexican agriculture. Pet owners should plan ahead, find a USDA-accredited veterinarian who can perform the inspection, and obtain the certificate well before crossing the border. Failure to comply could result in being denied entry or having the pet held for inspection.
