This standard describes a method of Iodium-131, Caesium-134 and Caesium-137 massic activity (Bq/kg) determination in animal feed.
Today, the most commonly used method for identification and quantification of radioactivity from these radionuclides in feed samples is high-resolution gamma-ray spectrometry. It is based on analysis of full-energy peaks (FEP) of the emitted gamma rays. Therefore, care should be taken to use appropriate energy and efficiency calibrations for each detector and test portion used.
In this standard, general guidance on the preparation of feed samples is provided together with specific information on high resolution gamma-ray spectrometry of the three radionuclides Iodium-131, Caesium-134 and Caesium-137. More information on these and related topics can be found in specific standards referred to in this document. For example, generic advice on the equipment selection, detectors and quality assurance for gamma-ray spectrometry can be found in ISO 20042:2016. The current standard aims to be complementary to existing standards, as an aid to laboratory practitioners that are faced with a situation, which requires response to the current topic without having to go through and interpret standards with general descriptions of gamma-ray spectrometry in order to measure in a standardised way. This standard contains information specific to the three radionuclides that it covers. Examples are provided in Annex …(to be added).

This document describes a method for the determination of the sum total of six ergot alkaloids (ergocornine, ergometrine, ergocristine, ergotamine, ergosine and ergocryptine) and their inine epimer pairs by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) after clean-up by dispersive solid phase extraction (SPE).
The method has been validated for cereals and cereal-based food products.
The method has been validated in the range 13,2 µg/kg to 168 µg/kg for the sum of the twelve ergot alkaloids, in rye flour, rye bread and cereal products (breakfast cereal, infant breakfast cereal, and crispbread) that contained rye as an ingredient, as well as seeded wholemeal flour and a barley and rye flour mixture.
Method performance was satisfactory in the range 24,1 µg/kg to 168 µg/kg, however at lower concentrations RSDR values were greater than 44 %, and HorRat values exceeded 2,0, indicating the method may not be fully suitable at concentrations below 24 µg/kg for sum of ergot alkaloids, although it is suitable for screening at these concentrations. Method performance may be improved by inclusion of an isotopically labelled internal standard, but this was not available at the time of the method validation study.

The proposed deliverable specifies an alternative technical protocol for the validation of mostly non-proprietary methods in the field of microbiological analysis of food, animal feed, and environmental and primary production stage samples.
It is closely related to ISO 16140-2. The latter specifies the technical protocol for the validation of proprietary methods, including a classical interlaboratory study and a method comparison study to be conducted in one laboratory. The realization of classical interlaboratory studies demands a sufficient number of participating laboratories (at least 8 laboratories are required). There are many occasions where a sufficient number of participating laboratories is not available (e.g. when a new method is required quickly after an outbreak of a new microorganism). In this case, the validation cannot be considered as reliable any longer.
The proposed deliverable uses a modified protocol based on orthogonal, factorial studies. By selection of suitable influencing factors (technician, nutrient media, sample preparation, temperature, duration) a high certainty of the determined method validation parameters is obtained, so that the number of required collaborating laboratories can be reduced up to a minimum of 4.
This validation protocol can be used in different ways. If the 4 collaborators can be considered a “random sample” of independent and competent laboratories and from different organizations, the test method can be considered as being validated in the sense that accurate and precise measurements are to be expected from any competent laboratory. If the 4 collaborators can be considered a “random sample” of independent and competent laboratories from one organization, the test method can be considered as being validated in the sense that accurate and precise measurements are to be expected from any competent laboratory in this organization.

The proposed deliverable specifies the procedure for single-laboratory validation of mainly non-proprietary methods in the fields of microbiological analysis of food, feed, and environmental and primary production stage samples. Single-laboratory validation is required if an interlaboratory validation according to ISO 16140-2 is not appropriate, e.g. for in-house methods or when the required number of participating laboratories is not available. Single-laboratory validation is not part of the optimization of methods. It can be applied only for methods that are fully specified with regard to all relevant parameters (including tolerances on temperatures and specifications on nutrient media).
The proposed deliverable describes two protocols for single-laboratory validation, a conventional protocol, and a factorial protocol. The conventional protocol is a stepwise procedure; both the study design and the performance measures are derived from ISO 16140-2. The performance measures of the factorial protocol are also derived from ISO 16140-2; however, it is using an orthogonal, factorial study design. By selection of suitable influencing factors (technician, nutrient media, sample preparation, temperature, duration) a high certainty of the determined method validation parameters is obtained, so that the number of required individual tests can be reduced by more than 50 %.

This document specifies a liquid chromatographic method with triple-quadrupole mass spectrometry (MS/MS) detection for the determination of pentachlorophenol (PCP) in feed materials and animal feed.
The limit of quantitation (LOQ) for the PCP determination in guar gum, fatty acid distillates (FAD) and animal feed is 10 µg/kg. Individual laboratories are responsible for ensuring that the equipment that they use will achieve this limit of quantification.
The method is validated in an international collaborative trial for pentachlorophenol in compound feed, guar gum and fatty acid distillate in the range between 9 µg/kg and 22 µg/kg.
The results of the collaborative trial, in which 16 laboratories participated, have shown that the method is applicable for the determination of PCP in compound feed, guar gum and FAD at the desired limit of 10 µg/kg. Satisfactory results were obtained for one compound feed sample, guar gum and the two FAD samples (HorRat <2), while for the second compound feed sample a HorRat value of 2,2 was obtained.

aldrin;
dieldrin;
chlordane (as the sum of chlordane isomers and oxychlordane);
dichlorodiphenyltrichloroethane (DDT) (as the sum of isomers op'-DDT, pp'-DDT, pp'-TDE (pp'-DDD), and pp'-DDE);
endosulfan (as the sum of α-/β-isomers and endosulfan-sulphate);
endrin (sum of endrin and delta-keto-endrin);
heptachlor (as the sum of heptachlor and heptachlor epoxide);
hexachlorobenzene (HCB);
hexachlorocyclohexane isomers α-HCH (α-BHC), β-HCH (β-BHC), γ-HCH (γ-BHC or lindane);
photo heptachlor;
cis- and trans-nonachlor;
A limit of quantification (LOQ) for the mentioned OCPs of 5 ng/g should normally be obtained. However, 10 ng/g applies for heptachlor, aldrin, endrin, dieldrin, and endosulfan (α-/β-- and sulphate). Individual laboratories are responsible for ensuring that the equipment that they use, achieves these limits of quantifications. The LOQs apply to the individual OCPs.

non dioxin-like PCBs (ndl-PCBs), as the sum of PCB 28, 52, 101, 138, 153 and 180.
The method has been fully validated by a collaborative trial for the substances and corresponding ranges (ng/g) noted in Table 1.
The method has not been fully validated for oxychlordane, endrin ketone, cis- and trans-nonachlor and photo heptachlor in all matrices.
The method is not applicable to chlorocamphene (toxaphene), a complex mixture of polychlorinated camphenes. Chlorocamphene has a very distinctive chromatographic profile and is easily recognisable by GC/ECD. Positive identification of the toxaphene isomers can be performed by negative chemical ionisation mass spectrometry (NCI-MS), electron impact tandem mass spectrometry (EI MS × MS) or electron impact high resolution mass spectrometry (EI-HRMS), which is not within the scope of this method.
A limit of quantification (LOQ) for the mentioned organochlorine pesticides of 5 ng/g should normally be obtained. However, 10 ng/g applies for heptachlor aldrin, endrin, dieldrin, and endosulfan (α-, β- and sulphate). For the ndl-PCBs an LOQ of 0,5 to 1,0 ng/g should be obtained. The LOQs mentioned apply to the individual compounds (i.e. not the sum of two or more compounds). Individual laboratories are responsible for ensuring that the equipment that they used will achieve these LOQs. On customers' demand the standard may be applied to solely the analysis of PCBs or OCPs.

This document is applicable to the determination of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs), (together termed ‘dioxins’ (PCDD/Fs)) and dioxin-like PCBs and non-dioxin-like PCBs (dl-PCBs and ndl-PCBs) in animal feeding stuffs. Collaborative studies have been carried out. The method is suitable for the determination of dioxins, dl-PCBs and ndl-PCBs at the appropriate MRL in compound feed and ingredients e.g. oil, mineral clay. The method is applicable to samples containing trace level amounts of one or more dioxins, dioxin-like PCBs and non-dioxin-likePCBs. The limit of quantification (LOQ) is
- 0,05 pg/g (OCDD/F = 0,1 pg/g) for the relevant individual congeners of dioxins/furans,
- 0,05 pg/g for non-ortho PCBs,
- 10 pg/g for mono-ortho PCBs, and
- 100 pg/g for non-dioxin-like-PCBs.
For determination of dioxins and dioxin-like PCBs, the procedure can be used as confirmatory method as defined by Commission Regulation (EC) No 152/2009 for dioxins and dl-PCB in feed [1]. Confirmatory methods as described in this standard are high-resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS) methods. If only the analysis of non-dioxin-like PCBs is required, a GC-LRMS method can be used (e.g. EN 15741 [2]) provided that appropriate analytical performance criteria are met in the relevant range for the matrix of interest.

This procedure is limited to the validation of alternative (proprietary) confirmation methods that are intended to replace (partly or completely) the confirmatory procedure described in the standard method for the enumeration or detection of specific (group of) microorganisms. The "sample" to be used for confirmation shall be a suspected colony that has been obtained following the reference or alternative culture method procedure. It is however not intended for confirmation using a (pure) colony from an unknown origin. Validation studies according to this standard are intended to be performed by organizations involved in method validation.

This document describes a method for the determination of organomercury in seafood/fishery products by elemental mercury analysis. The method has been successfully valideted in an interlaboratory study with a working range from 0,013 mg/kg to 5,12 mg/kg (HORRAT values <2) in seafood/fishery products [1], [2]. The limit of quantification is approximately 0,010 mg/kg organomercury (referring to dry weight, expressed as mercury) [3], [4].
Organic species of mercury, other than monomethylmercury, are also extracted and thus determined with this method. However, in seafood/fishery products the contribution from organic species of mercury other than monomethylmercury is negligible.

This document describes a screening method for the determination of aflatoxin B1, deoxynivalenol, fumonisin B1 and B2, ochratoxin A, HT-2 and T-2 toxins, and zearalenone in foodstuffs by high performance liquid chromatography (HPLC) coupled with tandem mass spectrometry (MS/MS).
The aim of the screening method is to test compliance of foodstuff with regulatory limits or to determine whether a certain pre-defined level (the screening target concentration, STC) is exceeded or not. The result of the screening is either "negative" or "suspect". "Negative" (screen negative) means that the targeted mycotoxins are not detected or potentially present but below the STC. "Suspect" (screen positive) means that the established cut-off level is exceeded and the sample can contain one or more mycotoxins at a level higher than the STC.
For full identification and accurate quantification a second confirmatory quantitative analysis method is required which is outside the scope of this document.
The method is suitable for various types of foodstuff and has been validated for representative matrices from four commodity groups:
- high starch and/or protein content and low water and fat content: wheat, cereal mixture, wheat flour and cornflakes;
- high oil content: peanuts;
- high sugar low water content: figs;
- high water content: grape juice.
During validation, cut-off levels were established for the following screening target concentrations:
- aflatoxin B1: 2 µg/kg to 5 µg/kg;
- deoxynivalenol: 250 µg/kg to 865 µg/kg;
- fumonisin B1: 200 µg/kg to 790 µg/kg;
- fumonisin B2: 110 µg/kg to 230 µg/kg;
- ochratoxin A: 4 µg/kg to 9 µg/kg;
- T-2 toxin: 25 µg/kg;
- HT-2 toxin: 25 µg/kg to 50 µg/kg;
- zearalenone: 30 µg/kg to 100 µg/kg.

This document specifies a method for the detection of celery (Apium graveolens) in emulsion-type sausages (e.g. Frankfurter, Wiener).
Real-time PCR detection of celery is based on an 101 bp (base pair) sequence from the gene of the mannitol dehydrogenase (GenBank Acc. No. AF067082 ) of celery (Apium graveolens).
The method has been validated on emulsion-type sausages (Bavarian “Leberkäse”) spiked with celery. For this purpose meat batter containing mass fractions of 50 % pork meat, 25 % pork fat, 23 % crushed ice and 1,8 % of a mixture of sodium chloride, nitrite, nitrate, phosphates and ascorbates was prepared according to a standard procedure for emulsion-type sausage. The meat batter was spiked with either ground celery seeds or celery root powder to 1000 mg/kg. Lower spiking levels were obtained by diluting with celery-free meat batter. The batter was stuffed into casings and heated at 65 °C for 60 min [2].

This document specifies a high-performance liquid chromatographic (HPLC) mass spectrometric (MS) method for screening and quantification of melamine in the concentration range between < 1 mg/kg and 100 mg/kg feed.
The method is validated in an international collaborative trial for melamine in complete feed, complementary feed, feed material, milk replacer and pet food including canned pet food in the range between 1 mg/kg and 80 mg/kg with particular regard to the by the European Commission established maximum level of 2,5 mg/kg.
Laboratory experiences have shown that the method is also applicable for cyanuric acid in the same concentration range in complete feed (n=7), complementary feed (n=6), feed material (n=7, resp. 9), milk replacer (n=7) and pet food (n=7) including canned pet food.
Since the LC-MS/MS sensitivity for cyanuric acid is substantially lower than for melamine it has to be ensured that the LC-MS/MS system is in excellent working order. The method is applicable to feeding stuffs but not tested for pre-mixtures and feed additives.
Quantification of concentrations above 100 mg/kg is possible, but the method has to be validated by the operator.
