20、3ISO 13307:2013(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subj

21、ect for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IE

22、C) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committee

23、s are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be hel

24、d responsible for identifying any or all such patent rights.ISO 13307 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO Technical Committee TC 34, Food products, Subcommittee SC 9, Microbiology, in accordance with the Agreement on technical cooperation betwee

29、ocument, the following terms and definitions apply.3.1primary production stageincludes all the stages of food production from farm until harvest or entry to the slaughterhouse3.2laboratory samplesample prepared for sending to the laboratory and intended for inspection or testing4 General arrangement

30、4.1 GeneralThe parties concerned or their representatives may be given the opportunity to be present when sampling is performed.Whenever special, e.g statutory, requirements are given for the sampling and/or arise from a specific analysis to be performed, these requirements shall be followed.4.2 Sam

31、pling personnelSampling for microbiological examination shall always be undertaken by a person trained and experienced in the technique of sampling for microbiological purposes. ISO 2013 All rights reserved 1BS EN ISO 13307:2013ISO 13307:2013(E)4.3 Packing and labelling of samplesSamples shall be pa

32、cked in order to avoid cross-contamination and to prevent leakage or loss of moisture. They shall be clearly identified.The minimum details that shall accompany the samples are: the nature of the matrix, its identification, the name or initials of the person responsible for taking the samples, as we

33、ll as the date, time (if appropriate), and place of sampling.This information should be recorded on a form. One form can be used for several samples provided each has unique identification and the samples are accompanied by the sampling form which lists the sample details with their unique identifyi

34、ng codes.4.4 Preparation of a sampling formSamples shall be accompanied by a report, ideally completed on a standard form provided by the laboratory, signed or initialled by the sampling personnel. The report shall give the following particulars: the place, date and time (if appropriate)of sampling;

35、 the names of the sampling personnel; the nature, number, and identity of samples constituting the consignment; the purpose of sampling and the microorganisms to be sought.When appropriate, the report shall also include any relevant conditions or circumstances, and any special information relating t

36、o the product being sampled, e.g. difficulty in achieving representative samples.If any additives such as diluents, transport media or neutralizing agents are used, these shall be recorded.5 Diluents and disinfectants5.1 Diluents.5.1.1 General. Diluent used for moistening all kind of swabs (bootswab

37、s, stick swabs etc.): peptone salt solution prepared according to ISO 6887-1; buffered peptone water prepared according to ISO 6887-1; sterile water; potable water for samples where this would not interfere with the analysis, e.g. bootswabs.5.1.2 Medium for transporting swabs for specific purposes.

38、The general aim of these media is to ensure survival of the target population, e.g. Campylobacter are particularly sensitive to drying.Examples of transport media: buffered peptone water for Salmonella prepared according to ISO 6887-1; CaryBlair transport medium or equivalent; Amies charcoal transpo

39、rt medium or equivalent.In circumstances where the sample is acidic or alkaline, or may become so during transportation, it may be useful to use a buffered diluent.Consideration should be given, if enumeration is intended, to the possibility of multiplication of the target or competing organisms bef

However, if the use of disinfectant is suspected, but its composition is unknown, a neutralizer for general use (5.3.2) can be used

45、 13307:2013ISO 13307:2013(E)6 Apparatus and materials6.1 Sampling equipment and description.6.1.1 General. Non-disposable sampling equipment should be sterilized before use, e.g. by moist heat (autoclave) or dry heat (oven), according to ISO 7218. In certain situations, chemical decontamination may

46、be appropriate. After such treatment, the equipment should be clean, sterile and free of inhibitory substances. If the equipment needs to be reused while taking samples, sterilization shall be done preferably by flaming (see 6.1.10) or with 70 % volume fraction ethanol or with any other appropriate

47、disinfectant (refer to ISO 7218). Sealed packs containing multiple plastics disposable equipment (e.g. gloves, overboots, plastics bags) are suitable for use during sampling of products from the primary production stage. On each sampling occasion (e.g. each different farm), a fresh pack should be us

48、ed. During sampling, every precaution shall be taken to avoid contamination of the unused disposable materials/equipment.6.1.2 Gloves, disposable, single use, impervious, used during sampling to protect the sampler and to avoid cross-contamination. An alternative is to use plastics bags, inverted ov

49、er the hand(s).6.1.3 Overboots, strong clean plastics bags of appropriate size, or boot-shaped plastics covering made specifically to put over boots or shoes, used for two purposes: as biosecurity while visiting a farm to avoid introducing contamination; and to put over boots just before sampling with bootswabs (6.1.6).6.1.4 Fabric swabs, normally large sterile portions of cloth, such as gauze, cellulose-based sponge, woven or non-woven fabric which are used to swab large surface areas.6.1.5 Stick swabs, cotton-bud swabs an
