Foot-and-mouth disease (FMD) is one of the important diseases of pigs which often lead to a hazardous epidemic and causes serious economic losses to the pig industry. Currently, the epidemiological situation of FMD is uncertain in many regions of China and many outbreaks are not reported. This study was undertaken to investigate the sero-prevalence and immunization program optimization of serotype O of FMD through ELISA and IHA in pigs in Zhejiang. A total of 368 serum samples were collected from June to July in 2016. Out of these samples, 23 (6.79%, 95% CI 4.4-9.9) pigs were found positive for FMD antibodies with the further distribution of 9.09% (95% CI 4.6–15.7), 6.90% (95% CI 2.6–14.4), 5.49%, (95% CI 1.8-12.4) and 4.35% (95% CI 0.9-12.2) from Wenzhou, Lishui, Jinhua and Ningbo counties, respectively. For the first time, we investigated the seroprevalence and the immunization schedule of FMD in pigs and our results indicated serious concern with an uneven seroprevalence of this infectious disease in studied region. The best immunization time found was 40 days of age, with booster at 60 days of age.
