As to why the National Standard for Food Safety of Frozen Frozen Rice Products allows for the presence of Staphylococcus aureus, the Ministry of Health explained that Staphylococcus aureus is widely distributed in the air and soil, and that humans and animals are the main carriers, usually present in 50%. Or more healthy people are sensitive to heat in the nose, throat, hair, and epidermis, and are usually cooked and cooked to kill. Staphylococcus aureus food poisoning is mainly caused by the pathogenic enterotoxins it produces. Usually Staphylococcus aureus is more than 105 colonies per gram. It may produce pathogenic enterotoxin and cause food poisoning. Frozen rice products stored below -18°C are not conducive to the growth of Staphylococcus aureus and produce enterotoxins.

The Ministry of Health also stated that: The International Committee on Microbiological Standards for Foods ranks Staphylococcus aureus as a general pathogenic bacterium based on pathogenic bacteria and its risk of disease, and a three-stage sampling scheme is usually used. The specific meaning of the three-stage sampling scheme is: the number of samplings for the same batch of product (n), the limit value of the acceptable level of the microbiological index (m), the maximum allowable number of samples exceeding the m value (c), and the maximum safety limit of the microbiological index Value (M). The new standard adopts a three-stage sampling scheme and uses a multi-sample quantitative test result to comprehensively determine the specific regulations as follows: The limit for Staphylococcus aureus in raw frozen pre-packaged rice products is (n=5,c=1,m= 103 colonies/gram, M=104 colonies/gram). The cooked quick-frozen pre-packaged rice products Staphylococcus aureus were (n=5,c=1,m=102 colonies/g, M=103 colonies/g), that is, 5 samples were taken in the same batch, allowing The test value of all samples is less than or equal to 102 colonies per gram, allowing a test value of 1 sample to be between 102 colonies/g to 103 colonies/g; no sample test value greater than 103 colonies/g is allowed; And above the sample detection value is greater than 102 colonies / g.
