The race against the clock (and the worm)
President Claudia Sheinbaum just put a date on the calendar. In two months, he promises, the Sterile Fly Production Plant in Metapa, Chiapas will be completed. Their mission: declare war on the cattle screwworm (GBG), a pest that has paralyzed a crucial sector.
“I think it will be finished in two months,” Sheinbaum said about the factory, highlighting that it is a project with financial support… from the United States. Therein lies the dramatic irony.
Mexico builds with gringo money the solution to a problem that the gringos themselves used to close the border to our livestock last year. The decision to reopen it, the president acknowledged, “depends on that country.” Meanwhile, the clock keeps ticking.
A strategy with a trap (literal)
But it’s not all about waiting for the factory to spit out infertile flies. Sheinbaum revealed that the “Sembrando Vida” program team is already in action, manufacturing traps in the field.
“Traps that are not very complex that allow flies to fall there,” he explained. It is a double attack: sterile insects to break the reproductive cycle and physical traps to reduce the adult population.
Between the lines, it is a message of forceful activity. We are not just waiting for a plant, we are fighting the pest now, with what we have.
The domestic market holds… for now
And the ranchers caught in the middle of this health and political conflict? Sheinbaum painted a surprisingly resilient picture. Despite the border closure, they found a market within Mexico.
“Even with the border closed… they were able to have the market and they also increased prices,” he stressed.
His tone was one of recognition of a sector that reinvented itself under pressure. But any political analyst smells the warning among the optimistic words: this domestic solution has a limit. The pressure to reopen the border remains enormous.
The final act of this drama is not yet written. In two months we will have the sterile flies. What we do not have is a guarantee that Washington will open the doors. The ball, as Sheinbaum said, is in his court. Meanwhile, Mexico plays its cards: biological ingenuity and economic resistance.
