Mexican livestock parasite outbreak deemed safe for meat consumption

Officials in Tamaulipas say the presence of the worm barrenador in cattle does not compromise meat safety. Union Ganadera Regional de Tamaulipas president José Guerrero Gamboa explained that infected animals recover after treatment with ivermectin and other antiparasitics, and the meat can be sold and consumed once the wounds have healed, provided it is properly cooked.

In Guanajuato, a surge in cases – over 300 detections in livestock and pets and two confirmed human infections – has prompted Deputy Rocío Cervantes Barba to request that the Federal Health Secretariat and the National Service for Agro‑Food Safety intensify control measures. She highlighted more than 250 human myiasis cases reported nationwide in 2025‑2026 and called for state‑level inspection brigades and public‑awareness campaigns to prevent further spread.
