Taiwan is revising its regulations on feeding pigs with kitchen waste to prevent an African swine fever (ASF) outbreak, which could threaten the country's pork industry. The updates will allow only farms with at least 200 hogs to use food waste-based feed, due to their ability to operate three-stage sewage processing facilities. The changes, expected to be implemented in October, will decrease the number of farms permitted to feed pigs reheated leftovers from 676 to 403. This decision was prompted by the discovery of ASF-infected meat products smuggled from Vietnam and a temporary ban on leftovers at pig farms to curb the spread of the disease.
