ISO/TR 24476 Selection of Microbiological Test Methods for Preservation Testing: A Comprehensive Guide

The selection of microbiological test methods for preservation is governed by the International Organization for Standardization (ISO) standard ISO/TR 24476. This standard provides guidelines for selecting appropriate microbiological test methods to ensure the safety and quality of preserved products.

Legal and Regulatory Framework

Preservation testing is regulated by various international and national standards, including:

  • ISO 11133:2003 Microbiology of food and animal feeding stuffs -- Guidelines on preparation and production of culture media

  • ASTM E2594-11 Standard Guide for Selection of Microbiological Methods for Water and Wastewater

  • EN ISO 21528-1:2017 Microbiology of the food chain - Enumeration of microorganisms - Colony-counting techniques at the 90 confidence level - Part 1: General requirements

  • TSE 1000:2018 Foodstuffs -- microbiological standards

    • These standards ensure that preservation testing is conducted in accordance with internationally recognized protocols and guidelines.

    International and National Standards

    International standards, such as ISO/TR 24476, provide a framework for ensuring the quality and safety of preserved products. National standards, like those from Turkey (TSE), also play a crucial role in regulating preservation testing.

    Standard Development Organizations

    Standard development organizations, such as ISO, ASTM, EN, and TSE, work together to develop and maintain international and national standards. These organizations ensure that standards are up-to-date and reflect the latest scientific knowledge and technological advancements.

    Evolution of Standards

    Standards evolve over time as new research emerges and technologies advance. This ensures that preservation testing remains aligned with the latest scientific understanding and regulatory requirements.

    Standard Numbers and Scope

    Some relevant standard numbers and their scope include:

  • ISO 11133:2003 Microbiology of food and animal feeding stuffs -- Guidelines on preparation and production of culture media

    • Scope: Provides guidelines for preparing and producing culture media.

  • ASTM E2594-11 Standard Guide for Selection of Microbiological Methods for Water and Wastewater

    • Scope: Provides guidance on selecting microbiological methods for water and wastewater testing.

  • EN ISO 21528-1:2017 Microbiology of the food chain - Enumeration of microorganisms - Colony-counting techniques at the 90 confidence level - Part 1: General requirements

    • Scope: Specifies general requirements for enumeration of microorganisms in foods using colony-counting techniques.

    Standard Compliance Requirements

    Preservation testing must comply with relevant standards to ensure product safety and quality. Failure to comply can result in regulatory actions, recalls, or even litigation.

    The preservation testing service provided by Eurolab is necessary for ensuring the quality and safety of preserved products. This section explains why this test is needed and required.

    Business and Technical Reasons

    Preservation testing is essential for preserving food, pharmaceuticals, and other products that require long-term storage. Without proper testing, these products may spoil or become contaminated, leading to financial losses and regulatory issues.

    Consequences of Not Performing the Test

    Not performing preservation testing can result in:

  • Product recalls

  • Regulatory actions

  • Financial losses due to product spoilage or contamination

  • Loss of customer trust and confidence

    • Industries and Sectors Requiring Preservation Testing

    The following industries and sectors require preservation testing:

  • Food processing

  • Pharmaceutical manufacturing

  • Cosmetics industry

  • Water treatment plants

    • Risk Factors and Safety Implications

    Preservation testing helps identify potential risk factors, such as microbial contamination or spoilage. This ensures that products are safe for consumption and comply with regulatory requirements.

    Quality Assurance and Control Aspects

    Eurolabs preservation testing service includes quality assurance and control measures to ensure accurate results and compliance with standards.

    This section provides a detailed explanation of how the preservation testing service is conducted, including equipment, sample preparation procedures, and testing parameters.

    Eurolab uses state-of-the-art equipment, such as:

  • Microbiological incubators

  • Autoclaves

  • Spectrophotometers

    • These instruments ensure accurate and reliable results.

    Sample Preparation Procedures

    Sample preparation involves:

    1. Collecting samples from the product or storage area.

    2. Homogenizing the sample to create a uniform mixture.

    3. Inoculating the sample onto culture media plates.

    Testing Parameters and Conditions

    Preservation testing parameters include:

  • Temperature (e.g., 4C, 25C)

  • Humidity

  • Pressure

  • Sampling frequency

    • These parameters are specified in relevant standards.

    Measurement and Analysis Methods

    Eurolab uses various measurement and analysis methods, including:

    1. Colony-counting techniques

    2. Spectrophotometry

    3. PCR (Polymerase Chain Reaction)

    These methods ensure accurate detection of microorganisms and other contaminants.

    Test Results and Reporting

    Preservation testing results are reported in accordance with relevant standards. Eurolab provides detailed reports, including:

  • Test methodology used

  • Sample preparation procedures

  • Testing parameters and conditions

  • Results, including any contaminants detected

    • Conclusion

    ISO/TR 24476 Selection of Microbiological Test Methods for Preservation Testing is a crucial standard that ensures the quality and safety of preserved products. Eurolabs preservation testing service adheres to this standard and provides accurate results to ensure compliance with regulatory requirements.
