One year after the closure of the US border to the export of Mexican livestock due to the resurgence of the screwworm, the federal government is intensifying dialogue with Washington. President Claudia Sheinbaum explained this Monday that the measure is unilateral and that the priority has been to control the pest with investment in a sterile fly biofactory in Chiapas and support for ranchers in Sonora, Coahuila and Durango.

Sheinbaum recalled that Mexico has already eradicated this pest in the past with the sterile insect technique. Now, the new plant in Metapa de Domínguez, Chiapas, will produce an improved specimen, he said:
“There is a new specimen that is produced in the United States, which Cofepris is analyzing, being able to also produce it in this plant in Chiapas… it is more efficient because it is males that are released and it has double the productivity.”
The president pointed out that the outbreak entered Central America and that Mexico collaborates with Panama, which has advanced technology. Senasica specialists will give more details.
The Secretary of Agriculture and Rural Development is working with the USDA and its head, Brooke Rollins, to release sterile flies and reopen the border. Sheinbaum highlighted that the closure also harms American ranchers and has raised the price of meat:
“What do we have to do? Seek dialogue, permanent communication so that it opens as soon as possible and work to eradicate the plague.”
In addition to the biofactory, the government trains producers in sanitation and wound cleaning. Sheinbaum said that Sonora and Durango are very advanced, while Coahuila is further behind. It is planned to expand support to other states to maintain the quality of export meat.
