Ranchers and veterinarians in Chiapas are confronting a rapid rise in New World screwworm fly cases, again prompting the U.S. to restrict Mexican cattle imports. Despite a history of outbreaks in the 1980s and 1990s, many ranchers are unprepared. Mexico plans to build a plant for sterile flies with U.S. assistance, but it's not ready until next year. Consequently, livestock treatment costs are soaring, forcing some ranchers to use home remedies. Veterinarian Alfredo Chávez is witnessing a rise in cases but reports little government support in combating the outbreak.
In the southern state of Chiapas, the New World screwworm fly's rapid spread has caught most ranchers off guard, despite previous outbreaks in the 1980s and 1990s.
Veterinarian Alfredo Chávez observed cases multiply, reporting dozens of cases and treating about a dozen animals himself, noting it affects not just cows but also sheep, pigs, cats, and dogs.
Treatment for infected livestock involves careful monitoring, multiple courses, and the high cost of medicines, leading some ranchers to resort to home remedies like gasoline or lime.
The Mexican government has provided minimal assistance, with veterinarians like Chávez stating, 'We've faced it alone,' as they navigate the outbreak with limited resources.
