This document specifies the determination of phytase activity in feeding stuff samples, including feed raw materials from plant origin, compound feeds (complete, complementary, mineral feeds), premixtures and feed additives.
The method is applicable to, and is collaboratively validated for, the determination of phytase activity in complete feed, complementary feed including mineral feed, premixtures and feed additives.
The method does not distinguish between phytase added as a feed additive and endogenous phytase already present in the feed materials. Therefore, the method is also applicable for feed materials from plant origin.
The method does not apply to evaluating or comparing the in vivo efficacy of the phytase product. It is not a predictive method of the in vivo efficacy of phytases present on the market as they can develop different in vivo efficacy per unit of activity.

This document describes a method for the quantitative determination of pyrrolizidine alkaloids (PA) in complete and supplementary feed and in forages by liquid chromatography tandem mass spectrometry (LC-MS/MS) after solid phase extraction (SPE) clean-up.
The method has been successfully validated in a collaborative trial for the matrices complete feed for horses, supplementary feed for horses, supplementary feed for rodents, hay, alfalfa and grass silage. Validation was carried out for the PA and concentrations ranges listed in Table 1. It was demonstrated that the PA isomeric pairs senecivernine and senecionine as well as senecivernine-N-oxide and senecionine-N-oxide cannot be determined individually due to insufficient chromatographic separation. However, the sums of the individual PA of the isomeric pairs were quantified with sufficient reproducibility. Co-elution of other PA-isomers not included in the scope of the method shall be taken into account. A list of potentially co-eluting isomers is presented in Annex E.
Although the calibration range of the method protocol is specified from 10 μg/kg to 300 μg/kg, the results of the collaborative study showed, that the dilution of sample extracts with blank sample extracts enables for the quantitation of concentrations exceeding the calibration range. Satisfactory reproducibility was achieved when quantifying up to 1428 μg/kg for individual PA and up to 887 μg/kg for the sum of isomeric pairs.
NOTE 1 A second method was part of the method validation collaborative main trial. For this method PA-N-Oxides are reduced by adding zinc powder to the extract of the feed material. The following steps correspond to the first and main method. Quantitative results for each PA except the otonecine type PA senkirkine represent the sum of the free PA base and its corresponding N-oxide.
NOTE 2 Due to insufficient numbers of data for some analyte-matrix combinations statistical evaluation was not valid for standardization. Received data indicated the methods applicability in experienced laboratories with appropriate quality assurance measures. Therefore, the method description is included as an informative annex (Annex D).

This document specifies a method for the determination of saturated and aromatic hydrocarbons (from C10 to C50) in feed. The method has been interlaboratory validated with on-line-HPLC-GC-FID – see [1], [2] and [3]. This method is not intended to be applied to other matrices.
The method can be used for the analysis of mineral oil saturated hydrocarbons (MOSH) and/or mineral oil aromatic hydrocarbons (MOAH).
The method is applicable for feed materials, in particular vegetable oils and other fat rich feed materials, compound feeds and pre-mixtures. It is not applicable to additives or deodistillates.
NOTE 1 The method was not designed for encapsulated matrices.
The method has been tested in an interlaboratory study via the analysis of both naturally contaminated and spiked samples (pre-mixture, soybean meal, sunflower seeds, chicken feed, pig feed, vegetable oil) ranging from 3 mg/kg to 286 mg/kg for MOSH and from 1 mg/kg to 16 mg/kg for MOAH.
According to the results of the interlaboratory study, the method has been proven suitable for MOSH and MOAH mass concentrations, each above 10 mg/kg. However, the method was not fully validated during the collaborative study for the premixture sample due to too low concentrations of MOSH and MOAH. The method was also not fully validated during the collaborative study for the sunflower seeds sample due to a too low concentration of MOAH.
NOTE 2 The conclusions regarding MOAH are based on 4 analyte / matrix combinations while the IUPAC protocol [4] expects this to be a minimum of 5.
In case of suspected interferences from natural sources, the fossil origin of the MOSH and MOAH fraction can be verified by examination of the pattern by GC-MS.
For the determination of MOSH and MOAH in edible fats and oils, another CEN standard is also available: EN 16995. For more information see [5].
Annex C proposes a manual alternative method to on-line HPLC-GC-FID analysis that can be used as a screening method for the determination of MOSH.

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 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.

This document specifies a gas chromatographic method with electron capture detection (ECD) for the determination of organochlorine pesticides (OCPs) in compound feeds and oil and fats.
The method is applicable to animal compound feed, oils and fats and fish meals with a water content up to about 20 % by weight and oil/fatty samples containing residues of one or more of the following OCPs, toxaphene and some of their isomers and degradation products:
— aldrin;
— dieldrin;
— dichlorodiphenyltrichloroethane (DDT) (the isomers op'-DDT, pp'-DDT, pp'-TDE (pp'-DDD), and pp'-DDE);
— endosulfan (as the sum of α-/β-isomers);
— endrin;
— hexachlorobenzene (HCB);
— hexachlorocyclohexane isomers α-HCH (α-BHC), β-HCH (β-BHC), γ-HCH (γ-BHC or lindane);
For the following OCPs, the method is considered a screening method. Additional in-house validation is required for reporting validated data.
— chlordane (as the sum of chlordane isomers and oxychlordane);
— endosulfan-sulphate;
— delta-keto-endrin;
— heptachlor (as the sum of heptachlor and heptachlor epoxide);
— photo-heptachlor;
— cis
— and trans-nonachlor.
A limit of quantification (LOQ) for the mentioned OCPs of 5 µg/kg is intended to be obtained. However, 10 µg/kg 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.

This document specifies a gas chromatographic mass spectrometric (GC/MS) method for the determination of organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in animal feeding stuffs and oil.
The method is applicable to animal feeding stuffs consisting of less than 20 % by mass and oil/fatty samples containing residues of one or more of the following OCPs and PCBs and some of their isomers and degradation products:
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, as the 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;
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 document is split into four modules. Each module describes a part of the whole procedure (see Figure 1 and Figure 2) to be followed:
a) Module A: Description of standards which might be used;
b) Module B: Description of extraction procedures;
c) Module C: Description of clean-up procedures;
d) Module D: GC/HRMS determination.
Each module describes a part of the whole method as well as, when applicable, alternatives which should be equivalent. Each module has to be regarded as an example. Combining modules and/or alternatives gives a highly flexible, "performance based" procedure. It is permitted to modify the method if all performance criteria laid down in Commission Regulation (EC) No 152/2009 [1] are met.
Any deviation of the described method, combination of modules needs to be recorded as part of the QA/QC procedures of accredited laboratories and should be available on request.

This document describes a method for the determination of individual ergot alkaloids and tropane alkaloids in unprocessed cereals and cereal-based compound feeds by high performance liquid chromatography with tandem mass spectrometry (LC-MS/MS).
This method has been successfully validated by collaborative trial in the following matrices: rye, barley, wheat, complete feed for bovine, porcine and poultry. Validation in buckwheat produced acceptable results, but the relative standard reproducibility was higher for most analytes in comparison with the other matrices. This may be related to the matrix. The validated range of the method is approximately 10 to 250 µg/kg for individual alkaloids. Determination of concentrations above 250 µg/kg is possible by applying a higher spiking level and dilution of the sample extract, but this has not been validated in the collaborative trial.
The method is applicable for the determination, by means of one-point standard addition to the sample, of ergocornine in the tested range of 12 µg/kg to 221 µg/kg, ergocorninine in the tested range of 9 µg/kg to 196 µg/kg, ergocristine in the tested range of 14 µg/kg to 312 µg/kg, ergocristinine in the tested range of 12 µg/kg to 258 µg/kg, α-ergocryptine in the tested range of 10 µg/kg to 184 µg/kg, α-ergocryptinine in the tested range of 8 µg/kg to 171 µg/kg, ergometrine in the tested range of 12 µg/kg to 174 µg/kg, ergometrinine in the tested range of 3 µg/kg to 172 µg/kg, ergosine in the tested range of 12 µg/kg to 226 µg/kg, ergosinine in the tested range of 9 µg/kg to 273 µg/kg, ergotamine in the tested range of 11 µg/kg to 443 µg/kg, ergotaminine in the tested range of 10 µg/kg to 273 µg/kg, atropine in the tested range of 16 µg/kg to 252 µg/kg and scopolamine in the tested range of 15 µg/kg to 246 µg/kg.
