nitrite.

In order to prevent food poisoning caused by eating nitrite by mistake and personal injury caused by drinking methanol by mistake, and to ensure people's health and life safety, catering service providers are prohibited from purchasing, storing and using nitrite (including sodium nitrite and potassium nitrite). Strictly prevent nitrite from being mistaken for salt and used as processed food.

catering service providers should try to purchase and use ethanol as heating fuel for dishes (such as chafing dish). When using methanol, propanol, etc. as fuel, color should be added for warning, and strict management should be carried out to prevent accidental drinking as liquor.
