Microbiology of food and animal feeding stuffs - Protocol for the validation of alternative methods

ISO 16140:2003 defines the general principle and the technical protocol for the validation of alternative methods in the field of microbiological analysis of food, animal feeding stuffs and environmental and veterinary samples for the validation of alternative methods which can be used in particular in the framework of the official control, and the international acceptance of the results obtained by the alternative method. It also establishes the general principles of certification of these alternative methods, based on the validation protocol defined in ISO 16140:2003. Where an alternative method is used on a routine basis for internal laboratory use without the requirement to meet (higher) external criteria of quality assurance, a less stringent comparative validation of the alternative method than that set in ISO 16140:2003 may be appropriate.

Microbiology of the food chain - Method validation - Part 1 : vocabulary

<p>ISO 16140-1:2016 defines general terms and definitions relating to method validation of microbiology in the food chain.</p> <p>It is applicable to the validation of methods for the analysis (detection or quantification) of microorganisms in</p> <p>- products intended for human consumption,</p> <p>- products intended for animal feeding,</p> <p>- environmental samples in the area of food and feed production, handling, and</p> <p>- samples from the primary production stage.</p>

Microbiology of the food chain - Method validation - Part 2 : protocol for the validation of alternative (proprietary) methods against a reference method

<p>ISO 16140-2:2016 specifies the general principle and the technical protocol for the validation of alternative, mostly proprietary, methods for microbiology in the food chain. Validation studies according to ISO 16140-2:2016 are intended to be performed by organizations involved in method validation.</p> <p>It is applicable to the validation of methods for the analysis (detection or quantification) of microorganisms in</p> <p>- products intended for human consumption,</p> <p>- products intended for animal feeding,</p> <p>- environmental samples in the area of food and feed production, handling, and</p> <p>- samples from the primary production stage.</p> <p>It is in particular applicable to bacteria and fungi. Some clauses of ISO 16140-2:2016 could be applicable to other (micro) organisms or their metabolites on a case-by-case-basis. In the future, guidance for other organisms (e.g. viruses and parasites) will be included in ISO 16140:2016 (all parts).</p>

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
