During the routine active FMD serological surveillance, NSP antibodies were detected on two pig farms located in Jiaosi (I-Lan) and Jhutian (P'Ing-Tung). The investigations showed that all pigs were clinically healthy. Fifteen serum and throat swab samples from each farm were collected and sent to the national laboratory (Animal Health Research Institute) for serological tests and virus isolation. The laboratory confirmed positive results with NSP antibody, whereas the results of virus isolation and RT-PCR were all negative. The serotype O was identified by using FMD ELISA kit.
The monitoring and epidemiological investigation of the Jiaosi farm and those surrounding farms that keep cloven-hoofed animals (a total of 26 pig farms, and 3 goat farms within 3-km radius of the index farm) have been done and no clinical or epidemiological evidence of infection was found.
The monitoring and epidemiological investigation of the Jhutian farm and those surrounding farms that keep cloven-hoofed animals are underway.
