FoodPT schemesQMS - Food microbiology schemeThe Quality in Microbiology Scheme (QMS) is aPT scheme intended for use by microbiologistsworking in the food and dairy industries.Food testing is an essential element of the‘Hazard Analysis Critical Control Point’ (HACCP)process in food production as it verifies thecontrols are working at the critical points inmanufacturing. Failures leading to food poisoningoutbreaks can have a devastating effect onreputation, brand value and ultimately profits.Failures which do not lead to an outbreak alsocan have an effect, leading to reduced shelf lifeand wastage. Over time can result in productdefects – affecting customer confidence in theproduct.Microorganisms may be reference strainssourced from national culture collections, ormay be fully characterised wild strains.Atypical strains may occasionally be includedin test materials. Atypical strains can occur in‘real’ foods and could be undetected ormis-identified. It is therefore a realistic challengeto occasionally include atypical strains within aPT scheme.The full range and availability of test materialsin QMS is determined on an annual basis andfurther details can be found in the QMSapplication form and scheme description.Test materialAnalytesLaboratories carrying out such microbiologicaltesting need to be able to demonstrate that theyare producing accurate and meaningful results.This can be done by conducting a comprehensivequality assurance programme, which includesregular participation in a suitable proficiencytesting (PT) scheme.The QMS scheme provides simulated food testmaterials in a choice of matrices that includesoatmeal and skimmed milk powder. The rangeof organisms offered for testing covers all thosethat are likely to be found in food and dairy,from spoilage organisms, pathogens, indicatororganisms and normal background flora.Oatmeal and SkimmedMilk PowderEnumeration:Aerobic psychrotrophs, Bacilluscereus, Coagulase positivestaphylococci, Coliforms,Clostridum perfringens,Escherichia coli,Enterobacteriaceae, Enterococci,Listeria monocytogenes, Lacticacid bacteria, Listeria species,Mesophilic aerobic spores,Thermophilic aerobic spores,Mesophilic anaerobic spores,Sulphite-reducing bacteria.Yeast/Mould,Osmophilic Yeast/Mould.Pseudomonas species,Salmonella species,Thermotolerant coliforms.Total aerobic mesophilic count,Total anaerobic mesophilic count.Presence/absence:Campylobacter species*,Clostridium species, Cronobacterspecies, Escherichia coli,Escherichia coli O157,Listeria species,Listeria monocytogenes,Salmonella species,Vibrio parahaemolyticus,Vibrio species,Yersinia enterocolitica.* Lyophilised vial formatNote: Test materials and analytes may be added or removed, pleasesee current application form.18 Tel: +44 (0)161 762 2500 Fax: +44 (0)161 762 2501
