FDA

FDA is the Food and Drug Administration (Food and Drug Administration) for short. FDA may also represent the United States FDA, that the US Food and Drug Administration, the FDA is an international medical audit authority from the US Congress authorized the Federal Government, specializing in the highest law enforcement authority of the Food and Drug Administration; is a by doctors, lawyers, microorganisms scientists, pharmacologists, chemists and statisticians and other professionals dedicated to protecting, promoting and enhancing national health monitoring government health regulatory agency. Many other countries to promote and monitor the safety of their own products through the FDA seek and receive help.
FDA certified food material
Refers to all food contact materials used in the manufacture, production, packaging, storage and transportation of food process, can come into contact with food materials. Common materials include various plastics, metals, ceramics, glass, wood products and so on. Environmental safety of these foods can come into contact with the material directly related to food safety and health of users. Therefore, these products are exported to the United States need to follow FDA standards related to testing and certification.
