China's national food safety standards have strict requirements on the use and safety management of nitrite, and it is safe to use nitrite according to the standards.

The national standard stipulates that sodium nitrite and potassium nitrite can be used as color fixatives and preservatives in the processing of cured meat products, braised pork products in sauce and smoked, roasted and barbecued meat, and the maximum dosage and residue are specified.

catering service providers should abide by the announcement on prohibiting catering service units from purchasing, storing and using food additive nitrite (announcement No.11 of the Ministry of Health in 2112): it is forbidden to purchase, store and use food additive nitrite (sodium nitrite and potassium nitrite).
