Foot-and-Mouth Disease in Bovines: A Global Threat to Livestock Health
Dec 25, 2025
Foot-and-Mouth Disease (FMD) is one of the most economically significant viral diseases affecting cattle and other cloven-hoofed animals worldwide. Due to its extremely high contagiousness and severe impact on livestock production and trade, FMD is classified as a notifiable disease by the World Organisation for Animal Health (WOAH).
What Is Foot-and-Mouth Disease?
Foot-and-Mouth Disease is caused by the Foot-and-Mouth Disease Virus (FMDV), a member of the family. The virus affects cattle, pigs, sheep, goats, and several wildlife species.
There are seven distinct serotypes of FMDV (O, A, C, SAT1, SAT2, SAT3, and Asia1). Immunity to one serotype does not provide protection against others, which makes disease control particularly challenging.
While adult cattle usually recover, calves may suffer high mortality due to viral myocarditis ("tiger heart").
The virus is highly resistant in the environment, which contributes to large-scale outbreaks if biosecurity is insufficient.
- Large-scale culling in outbreak zones
Even countries free of FMD invest heavily in prevention due to the potential economic devastation of an outbreak.
Early and accurate diagnosis is critical for FMD control. Common diagnostic approaches include:
- Antigen detection (e.g., rapid tests, ELISA)
- Molecular methods (RT-PCR) for virus identification and serotyping
Rapid on-site testing plays an important role in early screening, outbreak response, and surveillance programs.
Countries with intensive cattle industries rely on integrated prevention strategies to minimize risk.
Bovine Foot-and-Mouth Disease remains a major threat to global cattle health and the livestock industry. Understanding its transmission, clinical presentation, and diagnostic approaches is essential for effective prevention and control. With increasing animal movement and global trade, early detection and robust biosecurity measures are more important than ever.
