Key Players and Background
The United States has temporarily halted the importation of live cattle, horses, and bison from Mexico for 15 days due to a recent outbreak of the fly larvae (Cochliomyia hominivorax). This decision, announced by the US Secretary of Agriculture Brooke Rollins on May 11, has severe implications for both the Mexican and US livestock industries.
The Consejo Nacional Agropecuario (CNA), a prominent Mexican agricultural organization, has expressed concern that this suspension will significantly impact the northern Mexican livestock sector, which moves over 5,700 animals daily through Sonora and Chihuahua. Additionally, Mexico stands to lose approximately $11.4 million daily from livestock sales.
Understanding the Fly Larvae Outbreak
The fly larvae, or Cochliomyia hominivorax, is a parasitic larva that infests open wounds on warm-blooded animals. The feeding behavior of these larvae results in myiasis, a potentially fatal condition if left untreated. The recent outbreak in Oaxaca and Veracruz, Mexico, over 1,100 kilometers from the US border, prompted the US decision to prevent further spread of this pest.
Mexico’s Response
President Claudia Sheinbaum described the US decision as “unjust,” emphasizing that Mexico should not be subjected to arbitrary decisions by its neighbor. Julio Berdegué, Mexico’s Secretary of Agriculture and Rural Development (SADER), echoed this sentiment, stating that the US action is counterproductive to joint efforts against the fly larvae outbreak.
Berdegué pointed out that the US operates the sole laboratory producing sterile flies necessary to control the fly population in Panama. He accused the US of negligence in containing the 2023 outbreak. In response, Mexico has intensified border controls and proposed increased investment in sterile fly production and release, enhanced sanitary surveillance, and expedited authorization of crossing points with certified infrastructure.
