The Greater Tainan Government said that following suspected cases of bovine ephemeral fever (BEF) at three dairy farms, it has stepped up disinfection of the farms and surrounding areas.
Lee Chao-chuan (李朝全), head of the animal quarantine department, said over the weekend that the outbreak had not spread.
He said the department was notified recently by three dairy farms that a total of six cows had come down with fever and began drooling — symptoms associated with bovine ephemeral fever.
“We immediately counseled them on treatment and sent people to step up disinfection at and around the dairy farms,” Lee said.
He said the cows were recovering and that no new suspected cases have surfaced.
The city government has collected samples from the cows with suspected BEF infections and sent them to the Council of Agriculture for testing.
Lee said that all 21,000 cows in the municipality were vaccinated against the fever in June and July, but if the six cows are confirmed to have had the disease, the municipal government would consider moving back the standard inoculation period to around September.
Bovine ephemeral fever is a viral disease that affect cattle and buffalo. It is also commonly known as “Three-Day Sickness,” because affected animals typically fall sick for only a few days.
