Good Manufacturing Practices (GMP) is a term recognized throughout the world for the management of manufacturing and quality control testing of foods, medical devices and pharmaceutical products.

f the documentation showing how the product is made or tested is incorrect, then the product will be considered contaminated due to not meeting required specifications for the product. Good manufacturing practices requires that all testing and manufacturing equipment be qualified and shown to perform the function designed for the manufacturing and testing of the product.
