Commission Regulation (EU) 2015/705 of 30 April 2015 laying down methods of sampling and performance criteria for the methods of analysis for the official control of the levels of erucic acid in foodstuffs and repealing Commission Directive 80/891/EEC (Text with EEA relevance)

Commission Regulation (EU) 2015/705of 30 April 2015laying down methods of sampling and performance criteria for the methods of analysis for the official control of the levels of erucic acid in foodstuffs and repealing Commission Directive 80/891/EEC(Text with EEA relevance) THE EUROPEAN COMMISSION,Having regard to the Treaty on the Functioning of the European Union,Having regard to Regulation (EC) No 882/2004 of the European Parliament and of the Council of 29 April 2004 on official controls performed to ensure the verification of compliance with feed and food law, animal health and animal welfare rulesOJ L 165, 30.4.2004, p. 1., and in particular Article 11(4) thereof,Whereas:(1)Commission Regulation (EC) No 1881/2006Commission Regulation (EC) No 1881/2006 of 19 December 2006 setting maximum levels for certain contaminants in foodstuffs (OJ L 364, 20.12.2006, p. 5). sets maximum levels for erucic acid in vegetable oils and fats intended as such for human consumption, foods containing added vegetable oils and fats, infant formulae and follow-on formulae.(2)Commission Directive 80/891/EECCommission Directive 80/891/EEC of 25 July 1980 relating to the Community method of analysis for determining the erucic acid content in oils and fats intended to be used as such for human consumption and foodstuffs containing added oils or fats (OJ L 254, 27.9.1980, p. 35). establishes a method of analysis for determining the erucic acid content in oils and fats intended to be used as such for human consumption and in foodstuffs containing added oils and fats. This method of analysis has become obsolete and needs to be replaced.(3)It is appropriate not to establish a specific method of analysis but to establish performance criteria with which the method of analysis used for official control has to comply. Furthermore rules should be laid down concerning the method of sampling.(4)The measures provided for in this Regulation are in accordance with the opinion of the Standing Committee on Plants, Animals, Food and Feed,HAS ADOPTED THIS REGULATION:

Article 11.Sampling and analysis for the official control of the levels of erucic acid set in sections 8 of the Annex to Regulation (EC) No 1881/2006 shall be carried out in accordance with the Annex to this Regulation.2.Paragraph 1 shall apply without prejudice to the provisions of Regulation (EC) No 882/2004.

Article 2Directive 80/891/EEC is repealed.References to the repealed Directive shall be construed as references to this Regulation.

Article 3This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.

This Regulation shall be binding in its entirety and directly applicable in all Member States.Done at Brussels, 30 April 2015.For the CommissionThe PresidentJean-Claude JunckerANNEXPART A:DEFINITONSFor the purposes of this Annex, the following definitions shall apply:"lot"an identifiable quantity of food delivered at one time and determined by the official to have common characteristics, [such as origin, variety, type of packing, packer, consignor or markings]."sublot"designated part of a large lot in order to apply the sampling method on that designated part. Each sublot must be physically separated and identifiable;"incremental sample"a quantity of material taken from a single place in the lot or sublot;"aggregate sample"the combined total of all the incremental samples taken from the lot or sublot; aggregate samples shall be considered as representative of the lots or sublots from which they are taken;"laboratory sample"a sample intended for the laboratory.PART B:SAMPLING METHODSB.1.GENERAL PROVISIONSB.1.1.PersonnelSampling shall be performed by an authorised person designated by the Member State.B.1.2.Material to be sampledEach lot or sublot which is to be examined shall be sampled separately.B.1.3.Precautions to be takenIn the course of sampling, precautions shall be taken to avoid any changes which would affect the levels of erucic acid, adversely affect the analytical determination or make the aggregate samples unrepresentative.B.1.4.Incremental samplesAs far as possible incremental samples shall be taken at various places distributed throughout the lot or sublot. Departure from such procedure shall be recorded in the record provided for under point B.1.8 of this AnnexB.1.5.Preparation of the aggregate sampleThe aggregate sample shall be made up combining the incremental samples.B.1.6.Samples for enforcement, defence and referee purposesThe samples for enforcement, defence and referee purposes shall be taken from the homogenised aggregate sample unless this conflicts with the rules of the Member States as regards the rights of the food business operators.B.1.7.Packaging and transmission of samplesEach sample shall be placed in a clean, inert container offering adequate protection from contamination, from loss of analytes by adsorption to the internal wall of the container and against damage in transit. All necessary precautions shall be taken to avoid any change in composition of the sample which might arise during transportation or storage.B.1.8.Sealing and labelling of samplesEach sample taken for official use shall be sealed at the place of sampling and identified in accordance with the rules of the Member States.A record shall be kept of each sampling, permitting each lot or sublot from which the sample has been taken to be identified unambiguously. That record shall indicate all of the following:(i)reference to the number of lot from which the sample has been taken;(ii)the date and place of sampling;(iii)any additional information likely to be of assistance to the analyst.B.2.SAMPLING PLANSB.2.1.Division of lots into sublotsLarge lots shall be divided into sublots on condition that the sublot may be separated physically. The weight or number of sublots of products traded in bulk consignments shall be as given in Table 1. The weight or number of sublots of other products shall be as given in Table 2. Taking into account that the weight of the lot is not always an exact multiple of the weight of the sublots, the weight of the sublot indicated in Tables 1 and 2 may be exceeded by a maximum of 20 %.B.2.2.Number, weight and volume of incremental samplesThe aggregate sample shall be at least 1 kg or 1 litre except where this is not possible e.g. when the sample consists of one package or unit.The minimum number of incremental samples to be taken from the lot or sublot shall be as given in Table 3.In the case of bulk liquid products the lot or sublot shall be thoroughly mixed insofar as possible and insofar it does not affect the quality of the product, by either manual or mechanical means immediately prior to sampling. In this case, a homogeneous distribution of contaminants is assumed within a given lot or sublot. It is therefore sufficient to take three incremental samples from a lot or sublot to form the aggregate sample.The incremental samples shall be of similar weight or volume. The weight or volume of an incremental sample shall be at least 100 grams or 100 millilitres, resulting in an aggregate sample of at least about 1 kg or 1 litre. Departure from this method shall be recorded in the record provided for under point B.1.8 of this Annex.

Where sampling using the method set out in this chapter B.2 would lead to unacceptable commercial consequences (e.g. because of packaging forms, damage to the lot, etc.) or would be practically impossible, an alternative method of sampling may be applied provided that it is sufficiently representative for the sampled lot or sublot and is fully documented in the report provided for under point B.1.8.B.3.SAMPLING AT RETAIL STAGESampling of foodstuffs at retail stage shall be done where possible in accordance with the sampling provisions set out in point B.2.2.Where sampling using the method set out in point B.2.2 would lead to unacceptable commercial consequences (e.g. because of packaging forms, damage to the lot, etc.) or would be practically impossible, an alternative method of sampling may be applied provided that it is sufficiently representative for the sampled lot or sublot and is fully documented in the report provided for under point B.1.8.PART C:SAMPLE PREPARATION AND ANALYSISC.1.LABORATORY QUALITY STANDARDSLaboratories shall comply with the provisions of Article 12 of Regulation (EC) No 882/2004.Laboratories shall participate in appropriate proficiency testing schemes which comply with the "International Harmonised Protocol for the Proficiency Testing of (Chemical) Analytical Laboratories""The international harmonized protocol for the proficiency testing of analytical chemistry laboratories" by M. Thompson, S.L.R. Ellison and R. Wood, Pure Appl. Chem., 2006, 78, 145-196. developed under the auspices of IUPAC/ISO/AOAC.Laboratories shall be able to demonstrate that they have internal quality control procedures in place. Examples of these are the "ISO/AOAC/IUPAC Guidelines on Internal Quality Control in Analytical Chemistry Laboratories"Edited by M. Thompson and R. Wood, Pure Appl. Chem., 1995, 67, 649-666..Wherever possible the trueness of analysis shall be estimated by including suitable certified reference materials in the analysis.C.2.SAMPLE PREPARATIONC.2.1.Precautions and general considerationsThe basic requirement is to obtain a representative and homogeneous laboratory sample without introducing secondary contamination.All of the sample material received by the laboratory shall be used for the preparation of the laboratory sample.Compliance with maximum levels laid down in Regulation (EC) No 1881/2006 shall be established on the basis of the levels determined in the laboratory samples.C.2.2.Treatment of the sample as received in the laboratoryThe complete aggregate sample shall be finely ground (where relevant) and thoroughly mixed using a process that has been demonstrated to achieve complete homogenisation.C.3.PERFORMANCE CRITERIA FOR THE METHODS OF ANALYSISC.3.1.DefinitionsThe following definitions shall apply:"r"Repeatability the value below which the absolute difference between single test results obtained under repeatability conditions (i.e., same sample, same operator, same apparatus, same laboratory, and short interval of time) may be expected to lie within a specific probability (typically 95 %) and hence r = 2,8 × sr."sr"Standard deviation calculated from results generated under repeatability conditions."RSDr"Relative standard deviation calculated from results generated under repeatability conditions."R"Reproducibility the value below which the absolute difference between single test results obtained under reproducibility conditions (i.e., on identical material obtained by operators in different laboratories, using the standardised test method), may be expected to lie within a certain probability (typically 95 %); R = 2,8 × sR."sR"Standard deviation, calculated from results under reproducibility conditions."RSDR"Relative standard deviation calculated from results generated under reproducibility conditions."LOD"Limit of detection, smallest measured content, from which it is possible to deduce the presence of the analyte with reasonable statistical certainty. The limit of detection is numerically equal to three times the standard deviation of the mean of blank determinations (n> 20)."LOQ"Limit of quantification, lowest content of the analyte which can be measured with reasonable statistical certainty. If both accuracy and precision are constant over a concentration range around the limit of detection, then the limit of quantification is numerically equal to six or ten times the standard deviation of the mean of blank determinations (n> 20)."u"Combined standard measurement uncertainty obtained using the individual standard measurement uncertainties associated with the input quantities in a measurement modelInternational vocabulary of metrology — Basic and general concepts and associated terms (VIM), JCGM 200:2008.."U"The expanded measurement uncertainty, using a coverage factor of 2 which gives a level of confidence of approximately 95 % (U = 2u)."Uf"Maximum standard measurement uncertainty.C.3.2.General requirementsMethods of analysis used for food control purposes shall comply with the provisions of Annex III to Regulation (EC) No 882/2004.C.3.3.Specific requirementsC.3.3.1.Performance criteriaWhere no specific methods for the determination of contaminants in foodstuffs are prescribed at European Union level, laboratories may select any validated method of analysis for the respective matrix provided that the selected method meets the specific performance criteria set out in Table 5.It is recommended that fully validated methods (i.e. methods validated by collaborative trial for the respective matrix) are used where appropriate and available. Other suitable validated methods (e.g. in-house validated methods for the respective matrix) may also be used provided that they fulfil the performance criteria set out in Table 5.Further details are given in the Notes to the performance criteria as set out in this point.Where possible, the validation of in-house validated methods shall include a certified reference material.

Notes to the performance criteria:The Horwitz equationW. Horwitz, L.R. Kamps. K.W. Boyer, J.Assoc.Off.Analy.Chem.,1980, 63, 1344. (for concentrations 1,2 × 10– 7 ≤ C ≤ 0,138) and the modified Horwitz equationM. Thompson, Analyst, 2000, 125, 385-386. (for concentrations C < 1,2 × 10– 7) are generalised precision equations which are independent of analyte and matrix but solely dependent on concentration for most routine methods of analysis.Modified Horwitz equation for concentrations C < 1,2 × 10– 7:RSDR = 22 %where:RSDR is the relative standard deviation calculated from results generated under reproducibility conditionsC is the concentration ratio (i.e. 1 = 100 g/100 g, 0,001 = 1000 mg/kg). The modified Horwitz equation applies to concentrations C < 1,2 × 10– 7.Horwitz equation for concentrations 1,2 × 10– 7 ≤ C ≤ 0,138:RSDR = 2C(– 0,15)where:RSDR is the relative standard deviation calculated from results generated under reproducibility conditionsC is the concentration ratio (i.e. 1 = 100 g/100 g, 0,001 = 1000 mg/kg). The Horwitz equation applies to concentrations 1,2 × 10– 7 ≤ C ≤ 0,138.C.3.3.2."Fitness-for-purpose" approachFor in-house validated methods, as an alternative a "fitness-for-purpose" approachM. Thompson and R. Wood, Accred. Qual. Assur., 2006, 10, 471-478. may be used to assess their suitability for official control. Methods suitable for official control shall produce results with a combined standard measurement uncertainty (u) less than the maximum standard measurement uncertainty calculated using the formula below:where:Uf is the maximum standard measurement uncertainty (μg/kg);LOD is the limit of detection of the method (μg/kg). The LOD must meet the performance criteria set out in point C.3.3.1 for the concentration of interest;C is the concentration of interest (μg/kg);α is a numeric factor to be used depending on the value of C. The values to be used are given in Table 6.

PART D:REPORTING AND INTERPRETATION OF RESULTSD.1.REPORTINGD.1.1.Expression of resultsThe results shall be expressed in the same units and with the same number of significant figures as the maximum levels laid down in Regulation (EC) No 1881/2006.D.1.2.Recovery calculationsIf an extraction step is applied in the analytical method, the analytical result shall be corrected for recovery. In this case the level of recovery shall be reported.In case no extraction step is applied in the analytical method, the result may be reported uncorrected for recovery if evidence is provided by ideally making use of suitable certified reference material that the certified concentration allowing for the measurement uncertainty is achieved (i.e. high accuracy of the measurement) and thus that the method is not biased. In case the result is reported uncorrected for recovery this shall be mentioned.D.1.3.Measurement uncertaintyThe analytical result shall be reported as x +/– U whereby x is the analytical result and U is the expanded measurement uncertainty, using a coverage factor of 2 which gives a level of confidence of approximately 95 % (U = 2u).The analyst shall note the "Report on the relationship between analytical results, measurement uncertainty, recovery factors and the provisions in EU food and feed legislationhttp://ec.europa.eu/food/food/chemicalsafety/contaminants/report-sampling_analysis_2004_en.pdf".D.2.INTERPRETATION OF RESULTSD.2.1.Acceptance of a lot or sublotThe lot or sublot is accepted if the analytical result of the laboratory sample does not exceed the respective maximum level laid down in Regulation (EC) No 1881/2006 taking into account the expanded measurement uncertainty and correction of the result for recovery if an extraction step has been applied in the analytical method used.D.2.2.Rejection of a lot or sublotThe lot or sublot is rejected if the analytical result of the laboratory sample exceeds beyond reasonable doubt the respective maximum level laid down in Regulation (EC) No 1881/2006 taking into account the expanded measurement uncertainty and correction of the result for recovery if an extraction step has been applied in the analytical method used.D.2.3.ApplicabilityThe interpretation rules set out under points D.2.1 and D.2.2 shall apply for the analytical result obtained on the sample for enforcement. In case of analysis for defence or referee purposes, the national rules shall apply.
