In 2011, after the nuclear leakage accident at Japan's Fukushima nuclear power plant, food in Fukushima, Ibaraki, Tochigi and other places were contaminated with radioactive contamination. The shadow of "Lai pig" and "nuclear food" has not dissipated, and the "dark cloud" in Taiwan's food safety field has risen again.

In addition to imported comprehensive berries from large supermarkets Costco, strawberries imported from Japan were also found to contain banned pesticides. The "Food and Drug Administration" of the Taiwan authorities recently invited experts to discuss and chose to relax pesticide testing standards.
