In order to implement the source management, the Animal and Plant Epidemic and
Quarantine Bureau of the Executive Yuan Agricultural Committee conducted 45 samples for
the chicken farms and used the method developed by TFDA to verify that 3 domestic eggs had
Fipronil residues, and continued to launch a comprehensive survey of the source livestock farms.
In cooperation with the local inter-departmental department, a large-scale inspection of 1,459
eggs from chicken farms at the end of August was completed in just 5 days from the sampling
inspection to the completion of the inspection results. TFDA also assisted in the inspection of 50
eggs sent from the Tainan City Insurance Office (Figure 2-16).
TFDA actively develops inspection methods to help agricultural management units master

the information on contaminated chicken farms, conduct timely mobile control, speed up the
recovery of eggs, and develop administrative standards for residue tolerance to ensure consumer
safety.

(2) Investigation of Sudan IV Residues in Salted Egg Yolk
Mooncakes are the best-selling products during
Mid-Autumn Festival. In 2017, some salted egg
yolks in the mooncakes were found containing Sudan

red dyes which was recognized as carcinogens and
not allowed to be added in foods. TFDA developed
the rapid testing method to simultaneously detect
Sudan I, II, III, and IV in poultry products by liquid
chromatography-tandem mass spectrometer. This
method was applied to 10 cases of egg yolk (Fig.
2-17), and Sudan IV was found in 7 of them with Figure2-17 Salted egg yolk specimens

concentrations between tens to thousands ppb. The
results were further referred to the related authorities
including bureau of prosecution and investigation, and
health bureau to clarify the case.
