FDA introduction
FDA is short for food and drug administration. FDA sometimes also represents the US FDA, i.e. the US Food and drug administration. The US FDA is the international medical audit authority authorized by the US Congress, i.e. the federal government, and the highest law enforcement agency specialized in food and drug management. It is a professional composed of doctors, lawyers, microbiologists, pharmacologists, chemists and statisticians who are committed to protection, promotion and improvement National Health government health control monitoring agency. Many other countries seek and receive FDA assistance to promote and monitor the safety of their own products.
FDA certification of food materials
Food contact materials refer to all materials that can be contacted with food in the process of processing, production, packaging, storage and transportation of food. Common materials include various plastics, metals, ceramics, glass, bamboo and wood products, etc. The environmental protection and safety of these materials that can be contacted with food is directly related to the food safety and health of users. Therefore, the export of such products to the United States needs to be tested and certified in accordance with FDA standards.
The common inspection items of FDA certification for materials in contact with food are as follows:
