Molluscan Shellfish Tags: Attachment and Record Retention

Molluscan shellfish such as oysters, clams, and mussels can carry foodborne hazards. Identification tags help a regulator trace a product to its harvest area and shipment if illness or contamination is reported. A manager therefore has to maintain the tag through receiving, storage, and use—not throw it away when the package is opened.

Keep the tag connected to the product

The tag stays attached to the container until the shellfish is used up or the container is retagged under the applicable rule. This preserves the link between the shellfish and its source while product remains on site. Do not transfer shellfish to an unlabeled container and discard the original identification before the remaining product is traceable.

File the tag after the container is empty

Once the container is empty or retagged, retain the tag in chronological order for 90 calendar days after the date the container was emptied. A simple control is to write or otherwise document the empty date on the tag, then file it by date. Keep the record accessible for inspection and make sure staff know who closes out the tag when a container is finished.

Why the date matters

A delivery date is not the same as the date the container is emptied. The retention period runs from the empty date under the Food Code model. If the date is missing, staff may be unable to show that the establishment can trace a product that was served weeks earlier. Follow the jurisdiction’s adopted code and shellfish program requirements if they specify additional details.

Exam traps

• Removing the tag as soon as a container is opened.
• Starting the 90-day period on the delivery date rather than the empty date.
• Discarding tags without filing them chronologically.
• Assuming the FDA model code has identical legal effect in every jurisdiction.

Key takeaway

Keep shellfish traceable while product remains in the container, then date and file the tag for the required 90-day period. The tag is a food-safety record, not disposable packaging.

Keep shellfish identity attached to each lot Molluscan shellfish such as oysters, clams, mussels, and scallops can carry pathogens from harvest waters. Shellstock tags provide traceability to the harvester or dealer, harvest area, date, and lot. Keep the tag or labeling with the shellstock until the container is empty; do not combine tagged lots in a way that loses which shellfish came from which source. Verify that shellfish arrive from an approved source and that tags are legible and complete under the applicable code.

Store shellstock under proper temperature and conditions, in the original container or an approved food-grade container with the identifying tag maintained. Keep shellfish separated from raw meat, chemicals, and other contamination. Do not store them in a way that causes immersion in meltwater or cross-contamination. Follow any shellstock-specific refrigeration and display rules in the adopted code. If a tag is missing, illegible, or inconsistent with the shipment, isolate the product and contact the supplier; do not serve it until identity and source are verified.

Retention after the container is empty Under the FDA model, retain the shellstock tag or label in chronological order for 90 calendar days from the date the last shellfish from that container is sold or served. Write the date the container was emptied on the tag or maintain an equivalent record that links the shellfish lot and date. The retention period begins when the container is emptied, not when it is received. Local adoption may use the same rule or specify additional recordkeeping, so check the code and health department instructions in force.

This record enables traceback if a harvest area closes or illness reports emerge. A stack of tags without a date or link to the relevant container is not useful. Maintain records where managers can retrieve them quickly; do not discard them at the end of a shift or leave them attached to a container that is thrown away. Ensure employees know which shellfish types require tags and how to preserve records after repacking or partial use.

Scenario: an empty oyster box at close At close, an employee throws away an empty oyster box with its tag. The manager should preserve the tag, mark the date the last oyster was removed, and file it in chronological order. If another partially used lot remains, keep its tag with that product and do not transfer oysters into an unmarked pan. If tags were lost, contact the supplier immediately for traceability information and notify the health department if required; reconstructing a record later is less reliable than retaining the original tag.

If an illness report implicates oysters, stop serving the relevant lot, secure remaining product and tags, and follow regulator instructions. Do not discard the only evidence before the investigator can identify the harvest source. If there is an official harvest closure or recall, follow it regardless of whether the product smells or looks normal.

Exam traps and source hierarchy The 90-day clock is tied to the date the container is emptied. It is not 90 days from delivery, and it is not merely a supplier invoice retention period. Tags must remain associated with the lot and be retrievable. Shellfish safety relies on approved source and traceability; cooking or refrigeration does not replace that source control. FDA's 2026 Food Code is a model; the adopted state or local rule and current closure notices govern.

Train every handler on the tag handoff Receiving staff should know which shellfish shipments need tags and where tags are filed after emptying. Kitchen staff should keep tags with the original container until empty, and managers should verify that the emptiness date is legible before filing. If product is transferred to a service pan, maintain a link to its original lot and tag; never combine lots without preserving the identity of each. The record system should make it possible to retrieve the tag quickly by date or supplier.

Check invoices and tags together at receipt. A tag helps traceback but does not replace approved-source verification, proper receiving temperature, or shellfish-specific storage controls. If paperwork is incomplete, hold the shipment and contact the supplier before opening or serving it.
