ISO 22412 Determination of Mercury in Fish Laboratory Testing Service: A Comprehensive Guide
The determination of mercury in fish is a critical laboratory testing service that ensures the safety of human consumption. The International Organization for Standardization (ISO) has developed a standard, ISO 22412, which provides guidelines for the analysis of mercury in fish and other seafood.
Legal and Regulatory Framework
The legal and regulatory framework surrounding ISO 22412 Determination of Mercury in Fish testing is governed by various international and national standards. The European Unions Food Safety Authority (EFSA) has established maximum permissible levels of mercury in food, including fish and shellfish. The Codex Alimentarius Commission, a joint body of the World Health Organization (WHO) and the Food and Agriculture Organization (FAO), has also set guidelines for the maximum permissible levels of mercury in seafood.
