Mexico scales up national campaign to combat cattle screwworm outbreak

screwworm outbreak livestock health cattle exports sterile fly technique Mexico agriculture

Mexico is intensifying its fight against the cattle screwworm parasite through a transition from emergency response to a permanent national campaign. The federal government, led by the Secretariats of Agriculture and Science, has established a Technical-Scientific Council to coordinate efforts across 32 states, utilizing biotechnology and artificial intelligence.

In Sonora, the outbreak has increased to nine active cattle cases, primarily concentrated in Álamos. In Sinaloa, health authorities have confirmed two human cases of the infestation, though both patients remain stable. Meanwhile, Chihuahua has recorded 183 confirmed cases since July, with 62 cases currently identified in the municipality of Chihuahua. To combat the spread, the state has distributed over 4,000 preventive kits to livestock producers.

Control measures include the aerial and terrestrial release of millions of sterile flies to disrupt the parasite's reproduction. While cattle exports from Sonora have partially resumed through the Agua Prieta-Douglas border, the United States is maintaining a cautious reopening strategy due to the ongoing sanitary situation.
