The European Union has issued two warnings in September 2021 against Vietnamese export products, specifically frozen frog thighs and pomelos, for violations of food safety and hygiene regulations. The warnings were issued to Ngoc Ha Trading and Food Processing Co. Ltd for the presence of the banned substance Nitrofurans in frog thighs, and to "Nguyen Truc Thuy" for pomelos containing the prohibited substances Propargite and Fenobucarb. These contaminated products have been recalled or destroyed in France, Norway, and Switzerland. Vietnam's SPS Office has been notified and has been directed to review the production process and report the findings to the Ministry of Agriculture and Rural Development.
