The purpose of this compliance policy guide (CPG) is to provide guidance for FDA staff on adulteration associated with decomposition and/or histamine identified during surveillance sampling and testing of fish and fishery products susceptible to histamine formation.

The current CPG Sec. 540.525 is being revised to update FDA regulatory action guidance for sensory analysis and histamine levels in scombrotoxin-forming fish and fishery products.
