- Shelter dogs receive three months of specialized training to detect the scent of flesh-eating screwworms threatening livestock.
- These dogs operate primarily at the southern border in Chiapas, where infestations are most severe and disrupt cattle trade with the U.S.
- The U.S. has intermittently closed its border to cattle imports following new screwworm detections in Mexico, impacting trade.
- A $51 million sterile fly production plant, partly funded by the U.S., is scheduled to open in 2026 to reduce wild fly populations.
I would say 99% of the dogs are adopted by their handler. There is an unbreakable link because of the love between the handler and the dog.— Cesar Dangu, head of the canine training center Ceacan, describes the close bond between the dogs and their handlers.

- U.S. Agriculture Secretary Brooke Rollins announced an immediate suspension of live cattle, horses, and bison imports from Mexico due to the New World screwworm.
- Rollins emphasized the need to prevent a repeat of past infestations that severely impacted the cattle industry for decades.
- Mexico expressed strong opposition to the suspension and hopes for a swift resolution regarding the pest, which has been detected in Oaxaca and Veracruz.
- The suspension is set for an initial 15 days and will be reviewed monthly, as both countries are already facing economic repercussions.
