A recent incident of mixed loading in oil tankers has led to concerns about the safety of edible oil, causing panic and queues in supermarkets in Henan as brands run out. The incident has revealed that many tankers transport both edible and chemical liquids, sometimes without cleaning the tanks between loads. This has resulted in contamination of the edible oil. The incident has sparked public outrage and condemnation, particularly towards companies like Sinograin and Huifu Grain and Oil. Their products have been removed from online stores, and consumers are now more cautious about the source and safety of their cooking oil, with some opting for imported oil or making their own.
