Comprehensive Guide to JECFA PTWI Evaluation for Lead in Food Crops Laboratory Testing Service by Eurolab

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has established a Provisional Tolerable Weekly Intake (PTWI) for lead, which is a critical limit for ensuring the safety of food crops. The evaluation and testing of lead in food crops are governed by various international and national standards, including those set by ISO, ASTM, EN, and TSE.

International Standards

  • ISO 17294-1:2019 - Determination of cadmium, lead, mercury and arsenic content in foodstuffs and animal feed using flame atomic absorption spectrometry

  • ISO 17294-2:2019 - Determination of cadmium, lead, mercury and arsenic content in foodstuffs and animal feed using inductively coupled plasma mass spectrometry

  • ASTM E1010-18 - Standard Practice for Determining the Acceptance Criteria for Metal Contamination Limits for Foods

    • National Standards

  • EN 14254:2019 - Foodstuffs - Determination of lead content by flame atomic absorption spectrometry (FAAS)

  • TSE 1442:2020 - Foodstuffs - Determination of lead content by inductively coupled plasma mass spectrometry (ICP-MS)

    • Standard Development Organizations

    The International Organization for Standardization (ISO), the American Society for Testing and Materials (ASTM), and the Turkish Standards Institution (TSE) are among the leading standard development organizations responsible for creating and maintaining standards related to JECFA PTWI Evaluation for Lead in Food Crops testing.

    Legal and Regulatory Framework

    The evaluation of lead in food crops is subject to various regulations, including those set by the European Unions Food Safety Authority (EFSA), the United States Environmental Protection Agency (EPA), and the World Health Organization (WHO). These regulations dictate the acceptable levels of lead in food crops and require regular testing to ensure compliance.

    Standard Compliance Requirements

    Different industries have varying standard compliance requirements for JECFA PTWI Evaluation for Lead in Food Crops testing. For example, food manufacturers must comply with ISO 17294-1:2019 or ASTM E1010-18, while animal feed producers may need to adhere to TSE 1442:2020.

    JECFA PTWI Evaluation for Lead in Food Crops testing is essential for ensuring the safety of food crops and preventing potential health risks associated with lead contamination. This test is required by various industries, including:

  • Food manufacturing

  • Animal feed production

  • Agricultural practices
