Yucatán launches phase‑two trap program to curb worm infestation harming livestock and humans

The state of Yucatán is intensifying its response to a surge of the parasitic “gusano barrenador” that has infected livestock and caused human miasis cases. State officials report 2,259 animals affected and a cumulative 36 human cases, including one fatality, placing Yucatán fourth nationally behind Chiapas, Veracruz and Oaxaca.

In the second phase of the pilot suppression plan, 625 blue traps using a kairomone lure were deployed across 13 municipalities, managed by the Secretaría de Desarrollo Rural (SEDER), the Secretariat of Environment (SEMARNAT) and the Autonomous University of Yucatán (UADY). Rocío Chuc Mézquita explained that the blue traps “have a faster action and better preserve captured species.” Traps are checked weekly and specimens sent to laboratories for identification.

The program follows a first phase (January‑March) that installed 411 traps, collected 6,396 larval samples and identified 91 positive cases. Authorities urge producers to remain vigilant, continue inspecting animals, and report any signs of infestation, as emphasized by SEDR head Edgardo Medina Rodríguez.

Nationally, the federal health agency recorded 32,290 animal miasis cases across 28 states, underscoring the broader relevance of the Yucatán measures.
