Inspections were conducted at mushroom importer Hung Phat Green Technology Ltd. and supermarkets BigC Thang Long, Metro Thang Long and Sai Gon Coopmart Ha Noi.
Five mushroom types collected from these establishments all proved safe to eat after testing.
Additionally, no mushrooms were found from the northern province of Lang Son's Luu Mai Huong establishment, which has been accused of distributing mushrooms without clear origin.
