We make low risk RTE confectionery products with a shelf life of 2 years or more. Currently, when a product is released we retain a sample from each lot for the duration of the products shelf life. I was always told that we retain the samples because it is an FDA requirement, I am in the process of implementing SQF level 2 and I was trying to update our procedures but I can not find any FDA or SQF requirement regarding sample retention.
The retain samples are separate from our inspection and analyses samples that we collect when approving a product for release. Some customers require us to retain samples for future testing and quality comparisons, so for some products we collect 100 grams to test, 100 grams to retest, 100 grams to retain per customer specs and then 100 grams to retain per FDA regulation. This is according to our existing procedure but I don't know where the author came up with the information.
When releasing finished product, is it a mandatory requirement for us to retain a sample from every lot/batch of product?
If so, then would someone be so kind as to provide me with a link or code to reference.
