Screwworm Case Found in Mérida Dog

Mérida, Mexico — The Mérida City Council, through its Unit for the Environment and Animal Welfare (UMABA), has confirmed a case of screwworm (Cochliomyia hominivorax) in a 13-year-old dog treated at the veterinary module in the Chichén Itzá neighborhood.

According to the agency, the animal arrived with visible lesions showing the presence of larvae. The veterinarians applied the protocol established by the National Service for Agrifood Health, Safety and Quality (Senasica), which includes deep cleaning of wounds, specialized removal of the parasites, and sending samples to a laboratory for confirmation.

The dog received immediate wound care, and the case was reported to Senasica. The municipal authorities emphasized that both the Municipal Veterinary Clinic and the Chichén Itzá module have trained personnel and equipment to handle this type of emergency in dogs and cats, in coordination with federal agencies.

UMABA reminded pet owners that they should not fear sanctions, quarantines, or euthanasia if their animals show symptoms, and the recommendation is to go to the veterinarian as soon as possible. "Most animals can recover if they receive timely attention," they stated.

Within the framework of the preventive campaign "No Wounds, No Screwworms," the City Council reiterated the call to constantly check companion animals, especially when they have injuries, as the success of the treatment depends on early detection.
