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.

This document specifies minimum performance requirements for methods that quantify the food allergens milk, egg, peanut, hazelnut, almond, brazil nut, macadamia nut, cashew, pistachio nut, walnut, pecan nut, lupine, sesame, mustard, soy, celery, fish, molluscs, crustaceans, and wheat in raw and processed foodstuffs. Within the scope of this document, minimum requirements for an LOQ (Limit of Quantification) will be derived from threshold data of allergic consumers. For quantitative antibody-based methods, a normative annex will describe what specific information the method developer needs to deliver and how performance characteristics shall be validated. Regarding PCR and LC-MS/MS, information on performance characteristics are in parts covered by EN 15634-1 and EN 17644. This document does not apply to fragmented or hydrolysed food allergens, such as casein hydrolysates or soy sauce. It also does not apply to methods that deliver qualitative results only. Methods that cover gluten-containing cereals (wheat, rye, and barley) with regard to coeliac disease are covered by EN 17254.

This document specifies the detection of Clostridium (C.) perfringens.
This document is applicable to:
—     products intended for human consumption;
—     products intended for animal feeding;
—     environmental samples in the area of food and feed production and handling;
—     samples from the primary production stage.
This horizontal method was originally developed for the examination of all samples belonging to the food chain. Based on the information available at the time of publication of this document, this method is considered to be fully suited to the examination of all samples belonging to the food chain. However, because of the large variety of products in the food chain, it is possible that this horizontal method is not appropriate in every detail for all products. Nevertheless, it is expected that the required modifications are minimized so that they do not result in a significant deviation from this horizontal method.
NOTE          Interlaboratory studies with a small number of participating laboratories (<10) were conducted for the following food categories:
—      ready-to-eat, ready-to-reheat meat products;
—      eggs and egg products (derivates);
—      ready-to-eat, ready-to-reheat fishery products;
—      processed fruits and vegetables;
—      infant formula and infant cereals (with probiotics);
—      multi-component foods or meal components.
It has also been validated with a small number of participating laboratories for the following other category:
—      environmental samples (food or feed production).
Since the method is not commonly used for samples in the primary production stage, this category was not included in the interlaboratory study. Therefore, no performance characteristics were obtained for this category. The method has not been validated for the category ‘pet food and animal feed’, as the test samples used for the interlaboratory study were already naturally contaminated with C. perfringens. Given the limited number of participating laboratories in the interlaboratory studies, the calculated performance characteristics can be used as indicative values of the method performance. For detailed information on the validation, see Clause 11 and Annexes C to F.

This document specifies the enumeration of Clostridium (C.) perfringens by colony-count technique.
This document is applicable to:
— products intended for human consumption;
— products for feeding animals;
— environmental samples in the area of food and feed production and handling;
— samples from the primary production stage.
NOTE This method has been validated in an interlaboratory study for the following food categories:
— ready-to-eat, ready-to-reheat meat products;
— eggs and egg products (derivates);
— processed fruits and vegetables;
— infant formula and infant cereals;
— multi-component foods or meal components.
It has also been validated for the following other categories:
— pet food and animal feed;
— environmental samples (food or feed production).
As this method has been validated for at least five food categories, this method is applicable for a broad range of
food. For detailed information on the validation, see Clause 11 and Annex C. Since the method is not commonly
used for samples in the primary production stage, this category was not included in the interlaboratory study.
Therefore, no performance characteristics were obtained for this category.

appropriate in every detail for all products. Nevertheless, it is expected that the required modifications
are minimized so that they do not result in a significant deviation from this horizontal method.
This technique is suitable for, but not limited to, the enumeration of microorganisms in test samples
with a minimum of 10 colonies counted on a plate. This corresponds to a level of contamination that is
expected to be higher than 10 cfu/ml for liquid samples or higher than 100 cfu/g for solid samples.

a) handling of bacterial cultures;
b) axenic genomic DNA isolation;
c) library preparation, sequencing, and assessment of raw DNA sequence read quality and storage;
d) bioinformatics analysis for determining genetic relatedness, genetic content and predicting phenotype, and bioinformatics pipeline validation;
e) metadata capture and sequence repository deposition;
f) validation of the end-to-end WGS workflow (fit for purpose for intended application).
This document is applicable to bacteria isolated from:
—    products intended for human consumption;
—    products intended for animal feed;
—    environmental samples from food and feed handling and production areas;
