President Claudia Sheinbaum inaugurated the Production Plant for Sterile Livestock Screwworm Flies (GBG) in Metapa de Domínguez, Chiapas. It is a binational facility that will produce 100 million insects each week to control the pest that affects livestock.
Cooperation that pays off
The president highlighted that this project is the result of joint work between Mexico and the United States. The US government provided most of the resources, as well as technical expertise. Sheinbaum thanked President Trump and US Secretary of Agriculture Brooke Rollins.
“This Plant represents the conviction that development cooperation produces results. Animal diseases, pests and food security challenges know no borders,” said Sheinbaum.
Rollins called the inauguration a great achievement and recognized Sheinbaum as an extraordinary ally.
The United States ambassador to Mexico, Ronald Johnson, announced an additional investment of $83.8 million to strengthen pest control and increase the production of sterile flies in Mexico.
Operation details
Construction of the plant lasted 12 months. As part of the containment strategy, 5.3 million heads of cattle have been inspected, more than 84 thousand shipments have been verified and 7 billion sterile flies have been released. 2 thousand specialists, more than 400 thousand planters and 4 thousand technicians from the Sembrando Vida program participated. 578 thousand artisanal traps were installed, with which more than 13 million flies were captured.
Sheinbaum closed with a message: “Cooperation between sovereign countries will always be more powerful than confrontation when it comes to protecting the well-being of our people.”
