Oyster Safety Regulations in Dallas: Complete Health Code Guide

Dallas Local Health Code Requirements for Oysters

The City of Dallas Health Department enforces oyster handling standards based on Texas Food Establishment Rules (Title 25, TAC §229.261). All oysters must be obtained from Texas Parks and Wildlife Department (TPWD) certified suppliers and come with a valid shellfish tag documenting harvest location, harvest date, and dealer information. Raw oyster service requires a separate, dedicated preparation area to prevent cross-contamination with other foods. Restaurants must maintain detailed records of oyster purchases, including supplier certifications, for a minimum of 90 days for health department inspection and trace-back purposes.

Temperature Control & Storage Standards

Oysters must be stored at 45°F (7°C) or below, with daily temperature logs required by Dallas health inspectors. Live oysters cannot sit at room temperature for more than four hours total; once this window closes, oysters must be discarded. Dallas inspectors specifically check refrigeration equipment calibration and verify that thermometers meet NIST standards. Post-harvest pasteurization (heat treatment) is an alternative compliance method but is uncommon in raw oyster service. The holding time clock restarts if oysters are properly re-iced and documented.

Sourcing, Tagging & Inspection Focus Areas

All oysters served in Dallas must come from waters approved by TPWD and the Gulf Coast Shellfish Sanitation Program—never from unknown or private sources. The mandatory shellfish tag must remain attached until service and be retained by the restaurant for inspection. Dallas health inspectors focus on verifying tag legitimacy, checking harvest dates (oysters should be used within 10 days of harvest when properly stored), and confirming supplier licenses. Vibrio risk increases during warmer months (May–October), so inspectors intensify oversight during summer. Any oysters from closured waters or without proper documentation result in immediate citation and potential product seizure.
