There are three international food safety standards: the self-sufficiency rate is 95%; 4 kilograms of grain per capita; Grain reserves (grain stocks) should reach 18% of this year's grain consumption, 14% is the warning line, and less than 14% is the food emergency. There seems to be no separate standard in China.
