Complete Guide to ISO 11989 Validation of Microbiological Methods in Preserved Products Laboratory Testing Service

ISO 11989:2019 is an international standard that provides guidelines for the validation of microbiological methods in preserved products. The standard is developed and published by the International Organization for Standardization (ISO) and is available in multiple languages.

The standard is part of a broader family of standards that deal with microbiological testing, including ISO 11133:2014 and ISO 11290-1:2017. These standards provide guidelines for the sampling, preparation, and analysis of microbiological samples from food products.

Legal and Regulatory Framework

The use of microbiological methods in preserved products is regulated by various laws and regulations in different countries. For example:

  • The European Unions General Food Law Regulation (EC) No 178/2002 sets out general principles for the safety assessment of food.

  • The US FDAs Good Manufacturing Practice (GMP) regulations require manufacturers to establish and maintain procedures for ensuring the quality of their products.

    • International and National Standards

    Several international and national standards are relevant to microbiological testing in preserved products. Some examples include:

  • ISO 11989:2019

  • ASTM E2547-18: Standard Guide for Validation of Microbiological Methods for Food Products

  • EN ISO 11133:2014, Food processing - Microbiology - General guidance on methods for the detection of microorganisms

  • TSE EN ISO 11290-1:2017, Foodstuffs - Microbiology - Horizontal method for the detection and enumeration of Campylobacter spp. in food samples

    • Standard Development Organizations

    The standard development organizations that are relevant to microbiological testing in preserved products include:

  • International Organization for Standardization (ISO)

  • American Society for Testing and Materials (ASTM)

  • European Committee for Standardization (CEN)

    • Standard Evolution and Updates

    Standards evolve over time as new technologies, methods, and practices become available. This can lead to updates of existing standards or the development of new ones.

    For example:

  • ISO 11989:2019 is an update to the previous edition (ISO 11133:2006), which included new guidelines for the validation of microbiological methods.

  • ASTM E2547-18 was developed as a companion standard to ISO 11989:2019, providing additional guidance on the validation of microbiological methods.

    • Standard Compliance Requirements

    Compliance with standards is mandatory in many industries. For example:

  • Food manufacturers must comply with food safety regulations and standards, including those related to microbiological testing.

  • Pharmaceutical companies must comply with Good Manufacturing Practice (GMP) regulations and standards for their products.
