How long must shell stock tags be kept on file?

Shell stock tags must be kept on file for 90 days to ensure proper traceability of seafood products. This duration allows health officials to track the source of shellfish in case of foodborne illness outbreaks or contamination concerns. Keeping the tags for this period is important for maintaining public health safety as it assists in identifying the specific batch of shellfish consumed by individuals. After 90 days, the risk of needing to trace back to that specific batch diminishes significantly, making it the appropriate duration for retaining such documentation in compliance with health regulations.
