How long must shellstock tags be kept on file according to food safety regulations?

Shellstock tags must be kept on file for a minimum of 90 days according to food safety regulations. This requirement ensures that there is a record of where shellfish originated, which is important in the event of a seafood-related illness outbreak. The tags contain critical information such as the harvesting date and the source location, facilitating traceability and accountability in the supply chain. Keeping the records for 90 days allows health authorities ample time to investigate and manage any potential food safety issues related to shellfish consumption, thereby helping to protect public health.
