Guangdong province in China has implemented a three-tier local reserve system for edible vegetable oils to ensure they meet national food safety standards. The system includes types of oil such as soybean, peanut, blended, and rapeseed oil. These oils are subjected to quality testing by third-party organizations before being added to the local reserve supply. Since 2021, over 30% of the government reserve edible oil in the province has been inspected randomly, with a 100% pass rate for food safety indicators. However, public outrage and share price drops have been reported recently due to allegations of mixed and contaminated cargo transport by China Grain Reserves Group Ltd Co and mixed transport of edible oils at Jinlongyu's plants.
