This document specifies a real-time PCR procedure for the quantitation of the amount of roe deer DNA relative to total mammalian DNA in meat and meat products.
Results of this roe deer assay are expressed in terms of roe deer (Capreolus capreolus) haploid genome copy numbers relative to total mammalian haploid genome copy numbers. The content of roe deer can also be expressed as mass fraction in % using gravimetrically prepared calibration material from meat mixtures or model samples.
The method has been previously validated in a collaborative study and applied to DNA extracted from samples that consist of raw roe deer meat in a raw pig meat background as well as raw and boiled sausages.
The limit of detection of the roe deer PCR has been determined experimentally to be at least 5 target gene copies or at least 0,1 % roe deer.
The compliance assessment process is not part of this document.

This document specifies a horizontal in vitro method for the molecular identification and differentiation of the monophasic variant of Salmonella enterica subsp. enterica serovar Typhimurium (1,4,[5],12:i:-) lacking the second H phase H:1,2, starting from isolates. The method detects specific DNA sequences of an intergenic region of the first H phase flagellin cluster for identification of Salmonella enterica subsp. enterica serovar Typhimurium (further called Salmonella Typhimurium) and specific DNA sequences of genes associated with second H phase flagellar antigen expression.
The method is applicable for:
— differentiation of the isolate under analysis between monophasic Salmonella Typhimurium and the monophasic variant of another Salmonella non-Typhimurium serovar that has the same antigenic formula;
— identification of the isolate under analysis being either monophasic Salmonella Typhimurium or (biphasic) Salmonella Typhimurium.
This document is applicable for the analysis of a pure culture belonging to the genus Salmonella, isolated from:
— 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 document can also be applied in other domains for identification of monophasic Salmonella Typhimurium (e.g. environmental, human health, animal health).
NOTE This method has been validated in a method evaluation study and in an interlaboratory study with a large set of different strains (target and non-target strains), isolated from different sources (food products, animals, animal feed, primary production samples and humans). For detailed information on the validation, see Annex E.

This document specifies a real-time PCR procedure for the quantitation of the amount of equine DNA relative to total mammalian DNA in a raw meat sample.
Results of this equine assay are expressed in terms of equine (Equus genus) haploid genome copy numbers relative to total mammalian haploid genome copy numbers. This assay is specific for representatives of the genus Equus and therefore detects horse, mule, donkey and zebra DNA.
The method has been previously validated in a collaborative study and applied to DNA extracted from samples that consist of raw horse meat in a raw beef (meat) background.
The limit of detection has been determined experimentally to be at least 17 horse haploid genome equivalents (HGE) for both the equine PCR and the mammalian PCR based on the lowest dilution on the respective calibration curves through single laboratory validation. The lowest relative horse content of the target sequence included in the collaborative study was a mass fraction of 0,1 % based on gravimetrically prepared raw horse muscle tissue in a raw beef muscle tissue background.

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.

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.

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. This horizontal method was originally developed for the examination of all samples belonging to the food chain.
