AFAIK there are not any existing regualtions that would prevent you from re-working said material UNLESS the powers that be get involved and specifically state that it must be disposed
In Canada in poultry if there is an issue and product is being disposed, it has to be denatured to prevent it from appearing as food fit for consumption
Found some actual FDA information
- Determine and provide your course of action for out-of-business distributors.
- Provide a proposed method of destruction, if applicable.
- If the product is to be "reconditioned", explain how and where the reconditioning will take place. Please provide details of the reconditioning plan to your local FDA District Recall Coordinator before implementation. All reconditioning must be conducted under any applicable CGMPs.
- Describe how reconditioned product will be identified so it is not confused with recalled (pre-reconditioned) product.
In addition, we recommend that:
- You contact your local FDA District Recall Coordinator prior to product destruction. FDA will review your proposed method of destruction and may choose to witness the destruction.
- The recalling firm and customers keep adequate documentation of product destruction (and whether or not destruction was witnessed by an FDA investigator).
- Field corrections, (i.e. product relabeling), be performed by recalling firm representatives, or under their supervision and control. It is not recommended that a disinterested party such as a wholesaler or retailer be responsible for field corrections. For Drug Recalls: Misbranded drugs for re-labeling should be returned to the recalling firm.
- You contact your local District Recall Coordinator prior to release of reconditioned goods.
