Fipronil Pesticide Egg Contamination Strikes Again! Changhua Shunhong Farm Found with 3 Non-Compliant Samples, Products Sold to Taipei and New Taipei, Affecting Breakfast Vendors
The fipronil-contaminated egg incident has struck again! In 2017, an outbreak of eggs containing prohibited fipronil residues occurred across Taiwan, affecting over a million eggs (see the timeline at the end of this article). This year, a fipronil tainted egg incident has occurred again in Changhua! On January 25, agricultural authorities detected excessive fipronil residues in 3 egg samples collected from Shunhong Farm in Changhua County. The detected levels were 0.03, 0.04, and 0.06 ppm respectively (the residue standard is 0.01 ppm). The entire batch of non-compliant eggs was sold to Maoxin Hui Egg Company in Taipei City, which then distributed them downstream to individual vendors and breakfast vendors in Taipei and New Taipei, totaling 7,480 jin, approximately 74,800 eggs. Consumers may have already eaten them.
Currently, the eggs confirmed to contain fipronil residues total 7,480 jin (from the January 25 inspection batch, sold on January 27-28). Subsequently, Shunhong Farm sold an additional 1,929 boxes of eggs between January 29 and February 13 (38,580 jin, 385,800 eggs). Council of Agriculture Deputy Minister Huang Chin-cheng stated that these eggs may have all been "hit" and consumed by consumers. However, since several days have passed, fipronil may not necessarily be detectable. "Fipronil metabolizes very quickly in hens. The problematic eggs from January 25 may no longer be detectable after the 27th."
News Mini-Encyclopedia: Fipronil is a pesticide that can also be used as an environmental agent. It is prohibited for use in chicken farming. However, when used for different purposes, the applicable management methods and residue standards differ. As a pesticide, it can be purchased directly from pesticide stores. As an environmental agent, it is available in different concentrations. Some can be purchased by the general public, while others require vector control operators to submit a plan and obtain a permit after review and approval before purchase.
