According to a World Organisation for Animal Health report, African swine fever has been confirmed in Taiwan on a pig farm located on the western coast of the island nation. This is the first ASF occurrence in Taiwan. Samples were sent to the National Reference Laboratory for diagnosis on October 21, 2025 due to increased mortality rates. On October 25, 2025 the outbreak was confirmed as ASF. All control measures have been implemented since October 21, 2025. There were 301 susceptible pigs on the affected farm with 109 ASF cases noted and 106 deaths. The remaining 195 pigs on the farm were euthanized. WOAH reports that all appropriate response actions are being taken in Taiwan to limit the spread.

Taiwan is approximately 100 miles (160 km) off the southeastern coast of mainland China, separated by the Taiwan Strait. However, the closest point is much narrower, with some smaller Taiwanese-controlled islands, like Kinmen, being just a few miles from the Chinese mainland. Taiwan’s northernmost island is only 79 miles (128 km) from the northernmost island of the Philippines, Mavulis Island in Batanes.

Video: Four Star Pork Industry Conf - Back to Basics: Fundamentals drive vaccine performance

At a time when disease pressure continues to challenge pork production systems across the United States, vaccination remains one of the most valuable and heavily debated tools available to veterinarians and producers.

Speaking at the 2025 Four Star Pork Industry Conference in Muncie, Indiana, Dr. Daniel Gascho, veterinarian at Four Star Veterinary Service, encouraged the industry to return to fundamentals in how vaccines are selected, handled and administered across sow farms, gilt development units and grow-finish operations.

Gascho acknowledged at the outset that vaccination can quickly become a technical and sometimes tedious topic. But he said that real-world execution, not complex immunology, is where most vaccine failures occur.
