What should be checked on a label when receiving shellfish?

When receiving shellfish, it is crucial to check for shell stock tags. These tags provide important information about where and when the shellfish were harvested, as well as details about the supplier. They are essential for tracing the shellfish back to its source in case of a food safety issue, such as contamination or illness outbreaks. Ensuring that the shell stock tags are intact and properly filled out helps verify the freshness and safety of the shellfish being served, supporting proper record keeping for compliance with health regulations.

In the context of the other aspects mentioned, while expiration dates and allergen warnings are important for overall food safety and consumer protection, they are less specific to shellfish than shell stock tags. Cooking instructions, while necessary for preparation, do not directly address the safety and traceability of the shellfish being received. Therefore, shell stock tags serve a vital role in managing food safety for shellfish.
