4 SECTION 1 - INTRODUCTION Quality in Microbiology Scheme Food is embodied in every aspect of modern society, fulfilling sociological and cultural needs as well as basic survival and nutritional ones. All consumers should have confidence that the food they choose will be safe and wholesome to eat. Food is therefore regularly tested throughout the supply chain for the presence of undesirable micro-organisms, in order to ensure that it is of acceptable microbiological quality. Laboratories carrying out such microbiological testing need to be able to demonstrate that they are producing accurate and meaningful results. This can be done by conducting a comprehensive quality assurance programme, which includes regular participation in a suitable proficiency testing (PT) scheme. The Quality in Microbiology Scheme (QMS) is a PT scheme intended for use by microbiologists working in the food and dairy industries. The scheme includes a wide range of micro-organisms relevant to foods, including indicator organisms, spoilage organisms, and pathogens. Test materials Test materials are representative of food and dairy products. They may or may not contain the target organisms, along with relevant background flora. Inoculum levels for the target organisms will usually be within the following range; Detection tests 0 to 10,000 cfu g -1 Enumeration tests 0 to 100,000 cfu g -1 Micro-organisms may be reference strains sourced from national culture collections, or may be fully characterised wild strains. The full range and availability of test materials in QMS is determined on an annual basis and issued on a Schedule of Availability (Appendix I). Atypical strains may occasionally be included in test materials. Atypical strains can occur in real foods and could be undetected or mis-identified. It therefore represents a realistic challenge to occasionally include atypical strains within a PT scheme. Quality Control The quality of test materials is an essential factor of any PT scheme, with test materials required to be sufficiently homogenous, stable for at least the timescale of the round and similar in nature to the samples routinely analysed by participants. For QMS, quality control tests are performed on every batch of test material prepared. Quality control test results are reported in Appendix III. Performance Assessment The assigned value for enumerated parameters is the robust mean of participant results after transformation to log 10 (unless otherwise stated). The assigned value for qualitative parameters is determined from the test material formulation. All participant results are reported in tables as well as enumeration results being depicted graphically (Section 3). Additionally, each laboratory receives an individual summary of their submitted results. Enumeration results are subject to statistical assessment to help detect trends and enable comparison, using a performance indicator known as a z-score. All results are transformed to log 10 prior to statistical analysis. z score = (x X) σ x = the result reported by the participating laboratory X = the assigned value σ = the standard deviation for proficiency assessment The standard deviation used for proficiency assessment, also called the target standard deviation, is reported in Appendix II.

5 Advice/feedback Technical comments are included in Section 4. These describe the sample contents, the overall distribution of results, methodologies used and may also suggest possible reasons behind poor performance. Although not exhaustive, the most frequently identified reasons behind unsatisfactory results in QMS are described below: Calculation error Mis-calculation of the dilution factor or failing to take into account the volumes tested often gives results that are a factor of 10 or 100 times higher or lower than the assigned value. Poor quality agar or reagents Agar is highly sensitive to temperatures, particularly to overheating. Overheating can result in the release of compounds that may be detrimental to the growth of micro-organisms. Many selective agars also contain supplements that are intended to recover particular organisms, but if added at too high a concentration, can actually inhibit growth of the same organism, e.g. coliforms are sensitive to bile salts, which are used in agar selective for coliforms. Such problems can be monitored by the use of internal quality control checks using reference organisms. However, reference organisms are carefully nurtured for this very purpose, and stressed organisms, such as those found in foods and in proficiency test materials, will not be as robust. Inappropriate methodology Poor results may be due to use of inappropriate methods. For example, participants may report the use of VRBGA to obtain a coliform result, although this agar actually gives a total Enterobacteriaceae count. Transcription error Part of the challenge of performing laboratory tests is the ability to accurately report results. Transcription errors, e.g. reporting the right result but on the wrong form or in the wrong units, are just as important as any other source of error and care must be taken to check results are reported correctly. Inadequate confirmation Occasionally, participants assume that colony growth on selective agar is confirmation enough, and do not perform further, often relatively simple, confirmatory tests. Conversely, colonies may be immediately discounted if they do not initially appear as expected. Micro-organisms belonging to the same species can exhibit different characteristics, and it takes experience to correctly identify organisms from morphology alone. There are many other possible reasons for a single unsatisfactory result, including statistical chance. It is therefore important to interpret the results from PT schemes within the context of an all-round quality assurance programme, including internal quality control, use of validated methods and reference materials. A single poor result is not indicative of overall laboratory performance, but neither is a single good result. Ideally, PT results should be monitored over time to detect unusual bias or repeated unsatisfactory results which could be due to internal performance. In the event of obtaining an unsatisfactory result, repeat samples are available after every distribution. Further information on the scope and organisation of our proficiency testing schemes is available in the LGC Standards Proficiency Testing General Protocol and Individual Scheme Description.
