Screwworm Found in Abandoned Dog in Yucatán: 27th Case

Mérida, Yucatán — Ale Noh Basto, a rescuer with the animal welfare organization Las Huellitas de Franco y Fabio, confirmed the presence of screwworm in a mixed-breed female dog rescued in the municipality of Tetiz. Laboratory results and protocols established by health authorities verified the infestation.

Severe Injuries Led to Discovery

The rescuer reported that the dog, named “Dingo,” was urgently admitted to a veterinary clinic in Mérida after being found in Tetiz with deep wounds on her legs. According to Noh Basto, someone had tied the dog’s legs to immobilize her before abandoning her on the street.

Upon examination, veterinarians observed severe injuries infested with worms. Tests confirmed the presence of screwworm (Cochliomyia hominivorax), a parasitic larvae known to feed on living tissue.

Rising Cases in Yucatán

This case marks the 27th confirmed instance of screwworm infestation in Yucatán, as reported by the state’s Secretariat of Rural Development (Seder). Of these, two cases involve dogs—one in Tzucacab, in the southern part of the state, and now this case in Tetiz, located in the western region.

Authorities continue to monitor the situation, urging pet owners and livestock handlers to report suspected cases to prevent further spread.
