Good Manufacturing Practice is a set of regulations, codes, and guidelines for the manufacture of drugs (known as medicinal products in Europe), medical devices, diagnostic products, foods products and Active Pharmaceutical Ingredients (APIs). Since sampling products will statistically only ensure that the samples themselves (and perhaps the areas adjacent to where the samples were taken) are suitable for use, and end-point testing relies on sampling, GMP takes the holistic approach of regulating the production and laboratory testing environment itself. An extremely important part of GMPs is documenting every aspect of the process, activities, and of operations. If the documentation is not correct and in order, showing how the product was made and tested, that allows for traceability, and recall from the market in the event of future problems, then the product is considered contaminated (in the US considered adulterated).
