A fourth pig farm in Penang has tested positive for African Swine Fever (ASF), according to the Penang Veterinary Services Department (JPVPP), expanding on a previously reported outbreak involving three farms earlier this month.

Authorities say the situation remains under control, though thousands of pigs are being culled to curb the disease’s spread. 

Initial Infections Detected on July 12

The initial ASF outbreak was confirmed on Saturday, July 12, when laboratory tests from the Northern Zone Veterinary Laboratory verified infections at three pig farms in Kampung Selamat.

At the time, Penang Veterinary Services Department director Dr Saira Banu Mohamed Rejab said that two of the farms had experienced high mortality rates.
