Changhua County, Taiwan — November 12, 2025
Authorities in Changhua County have launched strict control and safety measures following the discovery of fipronil contamination in eggs from Wenya Livestock Farm. The contamination was confirmed after laboratory tests detected trace amounts of the banned pesticide in both egg and feather samples from the farm.
According to the Changhua County Animal Disease Control Center, samples were collected on November 10 and 11 for testing, including eggs, feed, soil, feathers, chicken organs, and water sources. The Central Livestock Council’s analysis revealed that one egg sample contained 0.03 ppm of fipronil metabolites, while one feather sample tested positive for 0.27 ppm of fipronil and 0.13 ppm of its metabolites. All other samples returned negative results.
In response, the Changhua County Government has immediately implemented comprehensive control measures to safeguard public health and prevent the spread of contamination.
