Biotechnological strategy for health control
MEXICO CITY.- The president of Mexico, Claudia Sheinbaum Pardo, has established a direct and conditioning correlation between the operation of a sterile fly production plant and the reopening of the US border to the export of Mexican livestock. This condition, imposed by the health authorities of the United States, responds to the need to definitively eradicate and control the plague of the cattle screwworm (Cochliomyia hominivorax), a parasite whose presence has profound economic and commercial implications.
A technical requirement for commercial standardization
During her morning conference at the National Palace this December 9, the president precisely explained the causal link. When asked if the opening of said facility is the requirement demanded by the United States, Sheinbaum responded affirmatively: “Well yes, because having this, there is much greater control of the pest than what is done now.” The current method, based on itinerant inspection in states with risk of contagion, is considered insufficient by North American counterparts, who demand a permanent and proactive biological control system.
The head of the federal Executive explained that, after a meeting with the Secretary of Agriculture and Rural Development, Julio Berdegué, the acceleration of work to put the plant into operation has been ordered. The sterile insect technique (SIT), on which this project is based, is not new; It has a history of approximately five decades in combating this parasite. Its mechanism is clear: millions of flies are bred, sterilized by radiation and released into the affected areas. The mating of these sterile specimens with the wild population leads to a progressive reduction and eventually the eradication of the pest, a protocol that the United States itself applies within its territory.
Schedule acceleration and economic impact
The initial time horizon projected the inauguration of the infrastructure for June of next year. However, the presidential instruction is “to be able to accelerate the work so that it can be done sooner.” This urgency is due to a first-order economic objective: unblocking access to the US livestock market. Sheinbaum argued that, although no cases have currently been recorded in the north of the country, the existence of this plant would provide “greater certainty” to international health authorities, facilitating border reopening.
This link is crucial to a broader strategic plan. The federal government has promoted a specific program with the states of Sonora, Coahuila and Durango, focused on the production of international quality beef. The final goal is to consolidate a productive chain that not only satisfies domestic demand, but also positions Mexico as a reliable and competitive exporter, complying with the strictest global animal health standards. The fly plant, therefore, is not only a pest control project, but a critical infrastructure for the foreign trade policy of the agricultural sector.
