Comprehensive Guide to FDA BAM Chapter 10 Listeria monocytogenes Detection Testing Services Provided by Eurolab

Listeria monocytogenes is a bacterium that can cause serious foodborne illness in humans, particularly in vulnerable populations such as the elderly, young children, and immunocompromised individuals. The detection of Listeria monocytogenes in food products is a critical step in ensuring consumer safety and compliance with regulatory requirements.

The FDAs Bacteriological Analytical Manual (BAM) Chapter 10 provides guidelines for the detection of Listeria monocytogenes in various types of foods, including dairy products, meats, and ready-to-eat foods. The BAM chapter outlines the recommended methods for sample preparation, culturing, and identification of Listeria monocytogenes.

The following standards are relevant to FDA BAM Chapter 10 Listeria monocytogenes Detection testing:

  • ISO 11290-1:2017 - Microbiology of food and animal feeding stuffs - Horizontal method for the detection and enumeration of Listeria monocytogenes - Part 1: Detection method
  • ASTM E2433-17 - Standard Practice for Enumeration of Listeria monocytogenes in Foods
  • EN ISO 11290-1:2017 - Microbiology of food and animal feeding stuffs - Horizontal method for the detection and enumeration of Listeria monocytogenes - Part 1: Detection method
  • TSE (Turkish Standard) TS EN ISO 11290-1:2017
  • These standards provide a framework for laboratories to follow when conducting Listeria monocytogenes detection testing. Eurolabs laboratory testing services are designed to meet or exceed these standards.

    The detection of Listeria monocytogenes is essential in ensuring consumer safety and compliance with regulatory requirements. The consequences of not performing this test can be severe, including:

  • Foodborne illness outbreaks
  • Product recalls
  • Loss of business reputation
  • Regulatory fines and penalties

    3. Culturing: Inoculate the prepared sample onto a selective agar plate.

    4. Incubation: Incubate the agar plates at 30C 0.5C for 48-72 hours.

    5. Identification: Identify presumptive Listeria monocytogenes colonies using standard microbiological techniques.

    The testing equipment and instruments used include:

  • Microbiological culture media
  • Agar plates
  • Incubators
  • Refrigeration units
  • The testing environment requirements include:

  • Temperature: 20-25C
  • Humidity: 40-60
  • Lighting: Ambient lighting
  • Air circulation: Moderate air circulation
  • Sample preparation procedures involve:

  • Homogenization of the sample
  • Inoculation of the prepared sample onto a selective agar plate
  • The testing parameters and conditions include:

  • Temperature: 30C 0.5C
  • Incubation time: 48-72 hours
  • Agar plate type: PALCAM or Oxford
  • Measurement and analysis methods involve:

  • Colony counting
  • Biochemical identification using API or Vitek systems
  • Calibration and validation procedures include:

  • Calibration of testing equipment
  • Validation of test protocols
  • Regular maintenance and calibration of equipment
  • Quality control measures during testing include:

  • Use of certified reference materials
  • Participation in proficiency testing programs
  • Regular review of test results and quality control data
  • The test report for Listeria monocytogenes detection includes:

  • Sample identification information
  • Testing dates and times
  • Test methods used
  • Results, including presumptive and confirmed positive colonies
  • Microbiological identification of presumptive Listeria monocytogenes colonies
  • Eurolabs laboratory testing services provide a comprehensive report that meets or exceeds the requirements outlined in FDA BAM Chapter 10.
