All raw materials, components, packaging, and labeling materials are held in our "quarantine" area until they are sampled, tested and/or examined, and released for use by our "quality control laboratory". The sampling is performed according to specific procedures by trained personnel. The procedures are designed to prevent contamination of raw materials, components, and packaging materials. Every raw material, component, packaging, and labeling material has its own test procedure and specification in writing and on file. When the "quality control laboratory" receives the samples, the respective test procedure is followed and the results documented and matched against the specifications. Upon release, each container of each lot number of raw materials, components, packaging, and labeling materials receives a green "release" sticker. Only containers bearing this "release" sticker are allowed out of quarantine and into the main warehouse.
