Oyster Safety & Regulations in Detroit

Michigan Oyster Sourcing & Certification Requirements

All oysters sold in Detroit must originate from FDA-approved, certified shellfish waters and be harvested by licensed dealers. The Michigan MDARD maintains a list of approved growing areas and requires documentation (harvest tags) for every batch received. Oysters cannot come from untested or unapproved waters, as they concentrate bacteria and viruses from their environment. Detroit establishments must verify supplier certifications and maintain records for a minimum of 2 years for traceability audits by the Wayne County Health Department.

Temperature Control & Storage Standards

Raw oysters must be stored at 45°F (7°C) or below, with daily temperature logs required by Detroit health code. Cooked oysters require holding temperatures of 165°F (74°C) or higher if served hot. Live oysters must display shells that close when tapped; any open or damaged shells require immediate disposal per FDA's Model Food Code, which Detroit adopts. Storage areas need proper ventilation to prevent ammonia buildup, and cross-contamination with ready-to-eat foods is strictly prohibited.

Detroit Health Department Inspection Focus Areas

Wayne County Health Department inspectors prioritize oyster safety during routine and complaint-driven visits, checking supplier documentation, temperature records, and storage conditions. They verify that staff follow proper handwashing and glove protocols when handling raw oysters, and that establishments remove oysters displaying deterioration or exceeding 7-10 day shelf life. Violations related to oyster handling can result in citations, operational restrictions, or temporary closures; establishments with Panko Alerts can track real-time inspection updates and outbreak notifications specific to their area.
