What CFGT and SAN describe
The official resources describe hygiene standards for restaurants and other food establishments. They help explain what a published standard means; they are not a live directory of every compliant business.
Thailand food-sanitation standards
The Department of Health publishes guidance for Clean Food Good Taste, CFGT Plus, SAN and SAN Plus. Use the official material to understand the standards, then verify a named food business separately.
Check the establishment, not only the standard
A standards document does not prove that a particular restaurant currently holds an award or meets a named level. Look for the current record tied to the business and confirm that the name and location match.
What this source cannot answer
The guidance does not provide live inspection status, opening hours, menus or customer reviews. Use it for the hygiene framework, not as a current restaurant recommendation.
