A control and eradication programme for foot-and-mouth disease (FMD) was initiated on a 1500-sow farm in Asia as an alternative to mass culling. The programme was based on mass vaccination and exposure to FMD virus to ensure the development of effective immunity throughout the population. Pigs are not long-term carriers of FMD virus and it should be eliminated by 21 days after infection. Entry of breeding stock was temporarily halted and the sow herd was partially depopulated in order to create a buffer between the infected and uninfected animals. After exposure to the virus and partial depopulation, the virus was eliminated through unidirectional pig flow and strict all-in/all-out procedures, and by thorough cleaning and disinfection of the buildings. Twelve months after the initial outbreak, the eradication plan was completed and successful. In parallel with the eradication programme, a small-scale isolated weaning project was carried out with the sow population that was moved out of the affected farm; 708 piglets were weaned to a separate facility 300 m away. No clinical signs of FMD were observed and the piglets remained serologically negative.
