26、O4002(E) ID:121 F002(4)E vi I SO dna ID 4002 F All irhgts seredevrIntroduction The principal reason for checking plant hygiene is to ensure that the plant will not contaminate the product. However, if contamination has taken place, it is possible to discover where in the circuit bacteriological infe
27、ction, chemical contamination or contamination from filth has taken place. Such checks will be necessary not only to ensure quality control requirements within the plant but also to ensure compliance of products with legal requirements. Also, the checks give information on the checking and sampling
28、procedures used to endorse the practices adopted to ensure cleanliness of the plant. There are three types of checks on the effectiveness of cleaning and disinfection for which sampling might be performed: a) checking all contact surfaces which have to be cleaned after and shortly before the product
29、ion process, and checking re-usable product containers (bottles, moulds, etc.) which have to be cleaned and which will hold the finished product intended for sale; b) indirect checking on solutions or methods used for cleansing; such checks will principally concern the different operations carried o
30、ut to ensure that optimum cleanliness is maintained; c) checking the raw materials or semi-finished products in the course of preparation or of finished products; in practice, such checks give a good idea of the quality of cleansing but they are ancillary to the quality of the raw material used and,
31、 in some cases, to the standard of hygiene of the operators of the plants.

32、ndard gives general guidelines for inspection and sampling procedures to be used to check the effectiveness of cleaning and disinfection methods used in dairy plants and receiving stations, including milk-collection tankers. It deals with visual inspection, sampling from plant surfaces (product line
33、, bottle washing equipment, containers, etc.), re-usable product containers, air, sampling of water and aqueous solutions other than those added to the product, and sampling of raw materials and products. It does not cover equipment normally installed in farms (e.g. milking machinery or refrigerated
34、 bulk milk tanks), nor does it deal with the equally important areas of health and hygiene of personnel, factory environment, internal arrangement of the factory, methods of cleaning, packaging materials brought in new from outside (paper, cardboard, plastic, new bottles, etc.), food ingredients and
35、 additives, selection of number of units and treatment of the sample in the laboratory. The need for sampling is normally considered in the design of plant. It is important that any devices which are included to enable samples to be taken are so designed and fitted that their use results in represen
36、tative samples being obtained without any adverse effect on the hygienic condition of the plant (e.g. by introducing dead spots in cleaning circuits). Such design is outside the scope of this International Standard. 2 Normative references The following referenced documents are indispensable for the

38、 ID:121 F002(4)E 2 I SO dna ID 4002 F All irhgts seredevr3 General instructions 3.1 The demands for effectiveness of cleansing operations vary from plant to plant depending on management supervision, quality control requirements and the type of production undertaken. 3.2 A cleansing control should n
39、ot be based solely on the results of microbiological tests even if such checks are clearly of prime importance; other checks (such as visual inspection, smell and touch, chemical and/or physical analysis and intelligent interpretation of records) are important in order not to overlook such factors a
40、s visible residues, malfunction of equipment, cleaning residues and corrosion. 3.3 Sampling for microbiological examination should be carried out only by personnel trained in sampling for this purpose. 3.4 The frequency of sampling depends essentially on the type of manufacture, the means of checkin
41、g available to the organization, and the costs acceptable to the organization in carrying out the checking. In theory, a check should be carried out after each cleansing or at a stated interval when cleansing is continuous during a production run (e.g. the case of a bottle washer), or just prior to
42、recommencement of production. However, in practice, a number of checks are carried out to ensure the quality of the product and those checks provide an indirect check on the efficiency of cleansing. Thus, in practice, the checking of effectiveness of cleansing depends upon the quality assurance for
43、the product, bearing in mind that a deterioration in quality is often due to failure in cleansing. 3.5 Generally, it can be said that the frequency of sampling should be determined by measuring the variability of the process and comparing this with the risk of making non-standard product. The optimu
44、m solution to this problem requires a good quantitative knowledge of the process, an understanding of statistical quality control, and deliberate management decisions on the degree of risk which is acceptable. 3.6 It is essential that samples be accompanied by a report which identifies the place, da
45、te and time of sampling, including any batch details, and the name and designation of the sampling personnel. Where appropriate, the report should include any relevant conditions or circumstances (e.g. the condition of the product containers and their surroundings, the temperature and relative humid
46、ity of the atmosphere, the method of sterilization of the sampling equipment, the location of the sampling point on the equipment, and whether a preservative substance has been added to the samples) and any special information relating to the product being sampled (e.g. difficulty in achieving homog
47、eneity of the product). 4 Inspection and sampling procedures 4.1 Visual inspection 4.1.1 An immediate and important impression of the cleanliness of a production line in a dairy plant can be obtained by visual inspection of the accessible parts of a plant. Included in this are all open containers an
48、d those closed with a lid, pipe fittings with their washers and gaskets, powder transport lines, air filters, parts which are operated by mechanical means (e.g. homogenizers, pistons, counting devices, stirrers and pumps) and re-usable product containers. Visual inspection should allow detection of
49、damage due to corrosion or erosion. 4.1.2 Visual inspection may be carried out using good natural or artificial light. Use of ultraviolet light should be resorted to only rarely because of the hazards involved. If ultraviolet light is used, it is more effective when the plant has been flushed with a fluorescine dye; it is essential to cleanse the plant fully after use of such dyes. Among many other confirmatory tests, the following may b
