Microbiology of the food chain - General requirements and guidance for microbiological examinations (ISO 7218:2024)

INB

This document specifies general requirements and gives guidance on microbiological examinations. It is applicable to: —     the implementation of specific horizontal or vertical International Standards developed by ISO/TC 34/SC 9 or ISO/TC 34/SC 5 for detection or enumeration of microorganisms, named hereafter “specific standards”; —     good laboratory practices for microbiology laboratories testing samples from the food chain; —     guidance for microbiological laboratories testing samples from the food chain on the technical requirements for conforming to ISO/IEC 17025. The requirements of this general standard supersede corresponding ones in existing specific standards. Additional instructions for examinations using the polymerase chain reaction (PCR) are specified in ISO 22174. This document is applicable to examinations for bacteria, yeasts and moulds and can be used, if supplemented with specific guidance, for parasites and viruses. It does not apply to examinations for toxins or other metabolites (e.g. amines) from microorganisms. This document is applicable to microbiology of the food chain, from primary production stage to food and animal feed products, including the premises where the food or feed production and handling takes place. It is also applicable to the microbiological examination of water where water is used in food production or is regarded as a food in national legislation.

SN EN ISO 7218:2024, titled "Microbiology of the food chain - General requirements and guidance for microbiological examinations," provides comprehensive guidance and specifies general requirements for microbiological examinations applicable to the food chain. It serves as a foundational standard that supports good laboratory practices and compliance with specific microbiological standards.

=== SECTION 1 ===

What SN EN ISO 7218:2024 covers

SN EN ISO 7218:2024 outlines the general requirements and guidance necessary for conducting microbiological examinations across the food chain. This standard applies to various sectors of the food industry, from primary production to the final products of food and animal feed. It encourages adherence to good laboratory practices, ensuring quality and reliability in microbiological testing. Importantly, the standard excludes examinations related to toxins or metabolic products, focusing specifically on bacteria, yeasts, and molds. Additionally, it sets the framework for laboratories to comply with ISO/IEC 17025, thus ensuring technical competence and reliability in testing practices. The guidance provided also extends to the microbiological examination of water used in food production.

=== SECTION 2 ===

Who needs to comply with SN EN ISO 7218:2024

The standard is relevant to a wide range of stakeholders within the Mathematics & Natural Sciences industry, particularly those involved in food safety and microbiological testing. This includes food manufacturers, processing plants, laboratories, and quality assurance professionals. Companies of all sizes, from small local producers to large multinational corporations, must comply with SN EN ISO 7218:2024 to ensure the safety and quality of their products. Roles such as microbiologists, laboratory technicians, and quality managers will find this standard essential for meeting regulatory requirements and industry best practices. Compliance not only affects operational integrity but also enhances consumer trust in food safety.

=== SECTION 3 ===

Key requirements

  • Implementation of Specific Standards: The standard serves as a foundational guide that supports the implementation of specific microbiological standards developed by ISO/TC 34/SC 9 or SC 5.
  • Good Laboratory Practices: It emphasizes adherence to good laboratory practices, ensuring that testing environments are suitable for reliable results.
  • Compliance with ISO/IEC 17025: Laboratories must meet technical requirements that align with ISO/IEC 17025, which focuses on competence and consistent results in testing.
  • Guidance on Microbial Testing: The standard provides specific guidance on the investigation of bacteria, yeasts, and molds, ensuring comprehensive examination processes.
  • Exclusions: It clearly states that examinations related to toxins and other metabolites, such as amines, are outside its scope.
  • Auditing: Compliance with these requirements is typically assessed through internal audits and external validation by accredited bodies.

=== SECTION 4 ===

How to implement SN EN ISO 7218:2024

Implementing SN EN ISO 7218:2024 involves several key steps. Initially, organizations should conduct a gap analysis to identify discrepancies between current practices and the standard's requirements. Following this, comprehensive documentation must be developed to align with the standard’s guidelines. Training sessions for personnel are crucial to ensure that all team members understand their roles in maintaining compliance. Internal audits should be performed periodically to assess adherence to the standard and to identify areas for improvement. Finally, organizations may seek a certification audit to validate their compliance with SN EN ISO 7218:2024, allowing them to demonstrate their commitment to microbiological safety and quality assurance.
