Safe Shellfish Storage for Food Trucks: Complete FDA Guide

FDA Temperature Requirements & Storage Standards

The FDA Food Code requires shellfish to be stored at 41°F (5°C) or below at all times. Live shellfish (clams, mussels, oysters) must be kept in containers that allow drainage while maintaining ambient temperature control—ice baths or commercial refrigeration units are standard. Raw shellfish cannot be stored above this threshold for any extended period, as pathogenic bacteria multiply rapidly between 41°F and 135°F (the 'danger zone'). Food trucks must use calibrated thermometers to verify internal cooler temperatures every 4 hours during operation, and these readings should be documented for health department inspections.

Shelf Life, Labeling, and Traceability Requirements

Live shellfish have a 7-10 day shelf life from harvest date if stored properly, though your local health department may impose stricter limits. The FDA requires shellfish to be labeled with harvest date, source, and tag/lot number—this information must come from your supplier on the original container. Implement a date-marking system: write the received date in permanent marker on containers and establish clear expiration dates based on local regulations. Keep all shellfish supplier documentation and tags for traceability; if contamination occurs, you'll need this to cooperate with FDA and CDC investigations. Missing harvest dates or source information is a critical violation during health inspections.

FIFO Rotation & Common Storage Mistakes

First In, First Out (FIFO) rotation prevents waste and reduces cross-contamination risk. When receiving shellfish, place new stock behind existing inventory and use older product first—shellfish stored longest should be served or discarded first. Common mistakes include storing shellfish directly on ice (they absorb moisture and deteriorate faster), mixing different delivery dates in one container, failing to separate shellfish from raw proteins in the cooler, and ignoring temperature fluctuations during truck shutdown or transport. Never repackage shellfish into unmarked containers; keep original tags and labeling visible. Temperature abuse from improper cooler maintenance or excessive door openings significantly shortens shelf life and increases bacterial growth risk.
