Egg safety remains a public concern. Changhua County has completed a special Fipronil monitoring program covering all layer chicken farms in the county. Testing results from 854 farms found no drug residues. Following a previous case involving Fipronil-contaminated eggs, the county launched a comprehensive sampling program to strengthen food safety management through source monitoring and risk control.

The project initially focused on farms that had previously recorded veterinary drug residue violations. The first round of testing covered 15 farms and found no abnormalities. The program was later expanded to all layer chicken farms in the county. Samples included eggs, feathers, feed and drinking water to assess potential residue risks, ultimately completing inspections at all 854 farms.

Results showed that none of the samples contained Fipronil residues. Authorities will continue monitoring and guidance programs through inspections, audits and educational outreach to strengthen livestock product safety management and maintain product quality and market confidence.

As Fipronil is prohibited for use in poultry farming, authorities will continue inspections, source verification and farm management guidance. With eggs being a staple food for many households, the county will continue monitoring production sources to ensure the quality and safety of eggs sold on the market.
