Hello, landlord! 1, QS, quality and safety sign! Because the melamine in milk powder once marked with QS exceeded the standard, some netizens ridiculed that QS is the abbreviation of "go to hell"! 2, the meaning of quality and safety, but everyone says it is to die, a QS represents no problem, it is useless, and it eats people. The AQSIQ focuses on the QS mark issued by the provincial quality inspection bureaus, that is, the food quality and safety market access mark, which refers to the certification mark issued by the relevant competent departments or organizations to producers in accordance with the prescribed procedures, indicating that the quality of products produced by enterprises has reached the corresponding level. At present, common quality marks include national inspection-free product marks, QS marks, production license marks and other foods. After being printed with QS marks, it has two meanings: First, food production and processing enterprises have passed the examination of necessary conditions to ensure food quality and obtained food production licenses; they have the environment, equipment and technological conditions for producing qualified foods; the raw materials used in production meet the relevant national regulations; the inspection and quality management in the production process meet the relevant national requirements; and the food packaging, storage, transportation and loading and unloading all meet the requirements. 2. The food has passed the factory inspection, and all indicators meet the requirements of relevant national standards. The QS mark shall not be used for food that has not obtained a food production license or failed the factory inspection. The inspection of ex-factory food is generally carried out by the inspection department set up by the producers themselves and passed the inspection. For enterprises that do not have the inspection ability and conditions, they can entrust legal product quality inspection institutions to conduct inspections. Simple, I hope the landlord will adopt it, thank you!
