Good Manufacturing Practice (GMP) is a common practice for the control and management of manufacturing and quality control testing of foods. It is also a worldwide recognized standard of food quality. Traceability is a very important issue of GMP. If the documentation showing how the product was made and tested is not correct or disordered, then the product does not meet the required specification and is considered as contaminated. Moreover, GMP requires all manufacturing and testing equipment has been qualified as suitable for use, and that all operational methodologies and procedures (such as manufacturing, cleaning, and analytical testing) utilized in the manufacturing process have been validated and written down as procedure in order to perform and access for their functions. By fulfilling the requirements set by GMP, corporations enjoy a lot of benefits.
