Coded and Records Retained
Meaningful coding of products
sold or otherwise distributed from a manufacturing, processing, packing, or
repacking activity should be utilized to enable positive lot identification to
facilitate, where necessary, the segregation of specific food lots that may
have become contaminated or otherwise unfit for their intended use. Records
should be retained for a period of time that exceeds the shelf life of the
product, except that they need not be retained more than 2 years.
