What should be done with shellstock ID tags after using the last shellfish from a stock?

The correct procedure for handling shellstock ID tags after using the last shellfish from a stock is to keep them for 90 days. This ensures compliance with food safety regulations, which are designed to trace shellfish back to their source in the event of a foodborne illness. The 90-day retention period allows health officials to track and identify the specific harvest area of the shellfish and to respond effectively if any safety issues arise. This practice is crucial in maintaining consumer safety and ensuring that any potential problems can be traced back to their source efficiently, thereby helping to prevent widespread illness. Keeping the tags for this time period demonstrates a commitment to food safety and traceability in the food service industry.
