A retail market wants to add a live molluscan shellfish display tank so customers can pick their own oysters. What does the Food Code require?

解析

Operating a molluscan shellfish life-support display tank is a specialized process the Food Code lists as requiring a variance and a HACCP plan, because the tank water and holding conditions can affect the safety of filter-feeding shellfish. The plan must address water treatment, monitoring, and records. Note the scope word 'Only': a consumer advisory is separately required wherever raw shellfish is offered, but it does not satisfy the variance requirement on its own. The routine establishment permit does not cover the tank, and the approval comes from the regulatory health authority, not a wildlife agency.
