This regulation provides clarifications on the hierarchy of food safety standards that have already been established and adopted as technical regulations, serving as points of reference for government agencies, international trading partners and local stakeholders. The scope of this regulation does not cover any requirements for compliance with regulatory procedures, issuances, or laboratory analyses, or any other substantial compliance costs to the stakeholders nor the government agencies. Tailored to meet the specific needs of Food Business Operators (FBOs), it serves as a clear reference point for determining the applicable food safety standards. The regulation offers alternatives for the regulatory agencies and the FBOs in cases of unavailability of PNS and Codex standards to cater the needs of the stakeholders while ensuring the safety of the plant foods.
