Introduction to Foot-and-Mouth Disease and its Impact
Foot-and-mouth disease (FMD) is a highly contagious viral disease affecting cloven-hoofed animals, such as cattle, sheep, and goats. This disease has recently caused concern in Mexico and the United States due to its potential economic and trade implications for both countries’ agricultural sectors.
Recent Cases in Mexico
Two New Infections Reported:
- A goat infected with FMD was discovered in the municipality of Tlatlaya, State of Mexico.
- Another infected animal, a calf, was found in the municipality of Llera, Tamaulipas.
Local health authorities promptly addressed the Tlatlaya case, treating the affected goat and administering preventive care to 20 other animals on the same ranch, as they were potentially exposed.
US Border Closure and Cross-Border Relations
United States’ Response to FMD:
In May, the United States closed its southern border to livestock imports following the detection of FMD cases in Mexico. This move aimed to prevent the spread of the disease across the border and protect the US livestock industry.
The FMD outbreak has strained relations between the two countries, as it impacts both Mexico’s and the United States’ cattle and beef industries.
Mexico’s Efforts to Contain the Outbreak
Mexican authorities have been actively working to control the spread of FMD, implementing measures such as:
- Rapid response to new cases, including immediate veterinary care and preventive treatments for exposed animals.
- Collaboration with international organizations to share information and best practices for controlling the disease.
- Public awareness campaigns to educate farmers and ranchers about FMD symptoms, prevention methods, and reporting requirements.
Statistics and Distribution of FMD Cases in Mexico
As of December 31, 2025, Mexico reported a total of 13,106 FMD cases since November 2024. Of these, 671 cases remained active.
The southern border state of Chiapas has the highest number of confirmed cases, followed by Oaxaca, Veracruz, and Yucatán.
