food microbiology (qms) round: 269

Aims of SchemeThe aim of the Quality in Microbiology scheme (QMS) is to enable laboratories performing the microbiological analysis of food and dairy products to monitor their performance and compare it with that of their peers. QMS also aims to provide information to participants on technical issues and methodologies relating to the microbiological examination of food and dairy products.

Further information on the scheme organisation, the test materials, and the statistical analysis of data are available in the QMS Scheme Description and the LGC PT General Protocol.

Performance AssessmentOnce a PT round has closed, the results will be analysed and the assigned value determined for each analyte, according to the criteria provided in the Scheme Description. Information regarding the traceability of each calculated assigned value is also provided in the Scheme Description.

For quantitative data, the participant’s result, x, (or log10 x for microbiological data) is converted into a z score using the following formula;

z = (x - X) SDPA

X = Assigned valueSDPA = Standard deviation for proficiency assessment

For quantitative data, the uncertainty of the assigned value is calculated to ensure that it would have a negligible effect on participants’ performance scores. If the uncertainty of the assigned value is greater than 0.3 x SDPA, then this is not considered negligible. In this situation, a z’ (z prime) performance score is automatically calculated rather than a z score, in order to take account of the measurement uncertainty of the assigned value. The z’ score is calculated using the following formula;

z’ = (x - X) √(SDPA2 + UxAV2)

X = Assigned value SDPA = Standard deviation for proficiency assessmentUxAV= Uncertainty of the assigned value ____ Expanded SDPA = √(SDPA2 + UxAV2)

Trend graphs will use a mixture of z and z’ scores, i.e. the ‘performance score’ for the round.

For quantitative data, gross errors or blunders are removed from the data by removal of any results that are greater than the assigned value ± 5 x SDPA. These results are not used in the final calculation of the assigned value and other summary statistics and will be included in the number of ‘Excluded Results’. All results, including excluded results, will be given a performance score.

For the purposes of performance assessment for a single round, z and z’ scores are interpreted as follows:

z/z’ score Interpretation Colour codingçzç≤ 2.00 Satisfactory result Green2.00 < çzçand < 3.00 Questionable result Amberçzç≥ 3.00 Unsatisfactory result RedNo score given See below No colour coding

Performance scores will not be given for the following:

§ For qualitative results, where satisfactory performance is based on the participants reporting the same result as the assigned result. E.g. detected, not detected. For these results, colour coding of green (satisfactory) or red (unsatisfactory) will apply.

§ For results of zero; such a result is not normally appropriate and should not be reported, the result should be reported as less than the detection limit rather than zero.Note: for a very small number of analytes it may be appropriate to report a result of zero, depending on the type of measurement scale being used.

§ For quantitative results where the analyte under test is present in the test material but participants report zero results or greater than results. In these cases, it is not possible to allocate a performance score and participants should assess their performance based on the assigned value and satisfactory range given.

§ For quantitative results where the analyte under test is present in the test material but participants report a ‘less than’ value. In these cases, it is not possible to allocate a numeric performance score, however, where the ‘less than’ value reported is < (AV-3*SDPA) the ‘less than’ value will be assessed as unsatisfactory (red colour coding), where the less than value reported is between < (AV-3*SDPA) and < (AV-2*SDPA), or > (AV+2*SDPA) the assessment will be questionable (orange colour coding) and it is recommend that you assess whether the method used is fit for purpose, and where the less than value reported is between (AV-2*SDPA and AV+2*SDPA) a satisfactory assessment (green colour coding) will be given as such results are deemed to be consistent with the assigned value.

§ For quantitative results, for microbiological test materials, where the analyte under test is not present in the test material, the assigned value will be classified as ‘Absent’. Results reported as ‘less than’ at or below the detection level for our method of confirmation will be assessed as satisfactory (green colour code). Results reported at a higher detection level will not be assessed and participants will need to use their own judgement to determine whether their result is fit for its intended use. Results reporting a positive count will be assessed as unsatisfactory (red colour code).

§ For quantitative results, for chemistry or clinical test materials, where the analyte under test has not been spiked into the test material, the assigned value will be classified as ‘Zero Spike’. A ‘less than’ value reported at or below the detection level, set as the assigned

Scheme Information

Issue: 1 of 123 09 October 2018

Round: 269Scheme: Food Microbiology (QMS)the assigned value will be classified as ‘Zero Spike’. A ‘less than’ value reported at or below the detection level, set as the assigned value, will be assessed as satisfactory (green colour code). A ‘less than’ value reported above the detection level will not be assessed and participants will need to use their own judgement to determine whether their result is fit for its intended use. Positive, numeric, results which are below the detection level, set as the assigned value, will not be assessed, whilst those that are greater than the assigned value will be assessed as unsatisfactory (red colour code).

In some cases, performance scores may not be provided or may be provided but with colour coding suspended (indicating that scores need to

be interpreted with caution). For example:

§ For small data sets where less than 8 results have been submitted and the assigned value is derived using a consensus value from the participants’ results. In these circumstances, there may be increased uncertainty of the assigned value, given the low number of participants, and performance scores will be given for information only.

§ In cases where the distribution of the results gives cause for concern e.g. bi-modal data sets. These circumstances will be dependent on the statistical design that is in place.

§ If the assigned value falls below a concentration threshold (only applies to some schemes).

In these or similar circumstances, further explanation as to the reasons for suspension of performance scoring or colour coding, and on the interpretation of results, will be given in the report.

Note: Data displayed in the report will have been rounded to the required number of decimal places. However statistical calculations will have been performed on unrounded data. For this reason, there may appear to be differences between displayed data and calculated data, but this does not affect results in any way.

ConfidentialityA unique laboratory reference code is used to report results in order to ensure confidentiality.

For quantitative testing, one-way ANOVA is used to estimate the analytical and sampling variance. For the sample to be considered sufficiently homogeneous for use in the PT scheme, the calculated sampling variance must be less than a critical value calculated according to the procedure described in the ISO 13528 [1].

For qualitative testing, the target analyte must be detected in 100% of test materials analysed.

For any analyte which has not been proven to be sufficiently homogeneous, and any closely related analytes, the value set for the SDPA may be suspended in order to take account of any potential inhomogeneity. The actual value used for the standard deviation for proficiency assessment is shown at the foot of the results and z-score tables in this report.

Often a particular test material does not require homogeneity assessment prior to distribution. Such sample types include standard solutions and aqueous solutions.

Test materials provided under the LGC scope of accreditation are assessed to ensure that they are sufficiently stable for the duration of the PT round. If test materials are subsequently shown to have changed significantly through the time of the PT round either, the effect of the instability will be quantified and taken into account in the performance evaluation or participant performance will not be evaluated.

Comments

The sample contained Salmonella Anatum at an approximate inoculum level of 3 cfu/g. The assigned value is therefore Salmonella species ‘detected’.

Salmonella Anatum is characteristic of the genus on selective media and in confirmatory tests, being H2S positive, motile, lactose negative,citrate positive and urease negative. It is a group E1 Salmonella according to the Kauffmann-White Scheme, with a full serological profile of‘O’ antigen: 3, 10; ‘H’ phase 1 antigen: e, h and ‘H’ phase 2 antigen: e, h.

Salmonellae are Gram-negative non-spore forming rods that are oxidase negative and catalase positive, and are members of theEnterobacteriaceae family. Almost all Salmonella serotypes cause acute gastro-enteritis and account for a large proportion of all foodpoisoning outbreaks. Primary sources of Salmonellae are the gastrointestinal tract of animals; the organism can be transmitted via faecesinto soil, water, feeds, foods and other animals, including humans.

The sample contained Listeria monocytogenes at an approximate inoculum level of 4 cfu/g. The assigned value is therefore Listeria species ‘detected’.

There are ten species of Listeria, the most clinically significant being Listeria monocytogenes, which is pathogenic for humans and animals.While other members of the Listeria genus are not usually implicated in disease, their presence indicates an increased risk of contaminationby Listeria monocytogenes.

Comments





The sample contained Enterococcus faecalis at an assigned value of 1,300 cfu/g.

Enterococci are widely distributed in the environment and are normal commensals of the intestinal tracts of animals, birds and humans. Theorganisms survive well in adverse conditions, and are resistant to heat, freezing, desiccation and chemicals, such as chlorine. For thisreason Enterococci are commonly used as indicator organisms, particularly in dried and frozen foods and also potable water samples.

The sample contained Clostridium perfringens at an approximate level of 4,400 cfu/g. The assigned value is therefore Clostridium species ‘detected’.

Clostridium is a large genus consisting of Gram-positive spore-forming anaerobes; they are usually straight rods which are catalasenegative. Some species are strict anaerobes, and some are aerotolerant. Clostridia are often found in soil, some are responsible for humanand animal disease, and others are associated with food spoilage. Clostridia are classified according to the shape and position of theirspores, and by their physiological characteristics.

Comments

The sample contained Escherichia coli at an assigned value of 66,364 cfu/g.

Coliforms are found in human and animal intestines, and their presence in foods is used as an indicator of faecal contamination. However,many coliforms are also found throughout the environment, being isolated from air, soil, water, plants, and animals. The presence ofcoliform indicator organisms in foods may, therefore, be indicative of faecal contamination, but may also be environmental in origin.

Comments





Escherichia coli is found in human and animal intestines, and, therefore, the presence of the organism in foods is thought to indicate faecalcontamination. It is historically used as an 'indicator' organism, to indicate whether more serious pathogens, such as Salmonella are alsolikely to be present.

Comments


Coliforms are found in human and animal intestines, and their presence in foods is used as an indicator of faecal contamination. However,many coliforms are also found throughout the environment, being isolated from air, soil, water, plants, and animals. The presence ofcoliform indicator organisms in foods may, therefore, be indicative of faecal contamination, but may also be environmental in origin.

Comments


Escherichia coli is found in human and animal intestines, and, therefore, the presence of the organism in foods is thought to indicate faecalcontamination. It is historically used as an 'indicator' organism, to indicate whether more serious pathogens, such as Salmonella are alsolikely to be present.


Sample: 17D - Staph/Bacillus

Comments

The sample contained Staphylococcus aureus at an assigned value of 3,400 cfu/g.

Staphylococcus species are mainly associated with the skin and mucous membranes of warm-blooded vertebrates, but are also found infood products, dust and water. Strains of Staphylococci other than Staphylococcus aureus are commonly referred to as coagulase-negativestaphylococci. They are not normally pathogenic, although they can cause wound and urine infections, and are not normally associated withfood spoilage.



Analyte: Coagulase positive staphylococci

Comments


The most significant food borne coagulase positive staphylococcus is Staphylococcus aureus. Staphylococcus aureus can be present onthe skin, and in the nose and throat of healthy individuals with no ill effect. It is important to test for it in foods as it can be an indicator ofgeneral hygiene and, and be a causative agent of food poisoning.


The sample contained Bacillus cereus at an assigned value of 6,100 cfu/g.

Comments





Bacillus is a large genus of Gram-positive bacilli that are aerobic, facultatively anaerobic and catalase positive. Bacillus species arewidespread in the environment, and are able to survive in adverse conditions due to the formation of endospores. They are able to survivein heat-processed and dried foods. Many species are normally present in soil and decaying animal and vegetable matter. Cells of bacilli arelarge and commonly adhere in chains.

Staphylococcus species are mainly associated with the skin and mucous membranes of warm-blooded vertebrates, but are also found infood products, dust and water. Strains of Staphylococci other than Staphylococcus aureus are commonly referred to as coagulase-negativestaphylococci. They are not normally pathogenic, although they can cause wound and urine infections, and are not normally associated withfood spoilage.

Comments


The most significant food borne coagulase positive staphylococcus is Staphylococcus aureus. Staphylococcus aureus can be present onthe skin, and in the nose and throat of healthy individuals with no ill effect. It is important to test for it in foods as it can be an indicator ofgeneral hygiene and, and be a causative agent of food poisoning.

Bacillus is a large genus of Gram-positive bacilli that are aerobic, facultatively anaerobic and catalase positive. Bacillus species arewidespread in the environment, and are able to survive in adverse conditions due to the formation of endospores. They are able to survivein heat-processed and dried foods. Many species are normally present in soil and decaying animal and vegetable matter. Cells of bacilli arelarge and commonly adhere in chains.

The sample contained Escherichia coli O157 (non-toxigenic strain) at an approximate level of 117 cfu/g. The assigned value is therefore Escherichia coli O157 ‘detected’.

Escherichia coli belongs to the Enterobacteriaceae family and the coliform group of indicator organisms. Cells of this organism are typicallyGram-negative rods that are motile, oxidase negative, produce gas from lactose at 37 and 44°C, possess the enzyme β-glucuronidase andproduce indole from tryptophan at 44°C. Some strains of Escherichia coli O157, in contrast, do not grow at 44°C and do not possess theβ-glucuronidase enzyme, so their presence may not be detected on chromogenic agars and in standard laboratory isolation procedures.Differentiation of Escherichia coli O157 from most other strains of Escherichia coli can usually be achieved using sorbitol MacConkey agar,as most strains of Escherichia coli O157 do not ferment sorbitol. There are also commercially available kits for confirmation of suspectcolonies, including latex agglutination kits.

Comments

The sample contained the mould Penicillium roquefortii at an assigned value of 4,400 cfu/g.

Visible mould growth can often be seen on foods, such as bread and vegetables, and in the environment, such as in bathrooms and airconditioning units. Many fungi are saprophytes, causing spoilage of foods and other commodities.

Comments

The sample contained the yeast Saccharomyces cerevisiae at an approximate level of 3,210 cfu/g. Lactic acid bacteria were not present in the sample therefore the assigned value is ‘absent’ using a detection level of <10 cfu/g.

Approximately 36% of participants correctly reported the absence of lactic acid bacteria from the sample. Due to the low number ofparticipants achieving the correct result internal quality control analysis was repeated on this test material. Results were consistent with theoriginal testing with the target organism being absent from all samples analysed. Enumeration results returned by participants wereconsistent with the level of yeast in the sample. Agars intended for the enumeration of lactic acid bacteria can also support the growth ofyeast; therefore participants should employ sufficient confirmatory techniques to ensure they have detected the target organism. In this casemicroscopy or a catalase test would have confirmed the absence of lactic acid bacteria. Participants gaining an incorrect result may wish toassess the significance of this internally.

Lactic acid bacteria are important in the food, brewing, and dairy industries where fermentation occurs due to their production of lactic andacetic acids. They are beneficial to health and are included in a number of probiotic foods. However, lactic acid bacteria can also causefood spoilage as high levels cause off flavours and odours and lead to a reduced shelf life. Lactic acid bacteria are often inhibitory to othermicro-organisms.

The test material contained Enterococcus faecalis. The correct identifications could therefore have been any of the following; Enterococcusfaecalis, Gram-positive cocci, Enterococcus sp.

A number of methods may be employed for the final identification of an organism, ranging from a simple Gram stain and biochemicaltesting, to serological and molecular methods such as latex agglutination and PCR.

The strain of Enterococcus faecalis included in the test material is a reference strain, and is a typical Enterococci. The strain is aGram-positive cocci and catalase negative. This particular strain was originally isolated from baby faeces. The organism producescharacteristic black/grey colonies on kanamycin aesculin azide agar, with surrounding blackening of agar. The organism reacts withLancefield group D.

The plates were prepared and photographed within the LGC laboratory. The assigned value of 610,000 cfu/g was determined internally byLGC based on counting the colonies on each plate and calculating the number of CFU in the original sample by taking the dilution andinoculum volume into account. The assigned value is therefore based on formulation.

For a result to be valid, in general it is considered that it is necessary to enumerate the CFU on at least one plate containing a minimum of15 CFU and not more than 300 CFU. The recommended counting limit may vary depending on the method employed, and participants areurged to consult the relevant standard if they are unsure. A total of 62 CFU were enumerated on the left hand plate and 60 CFU on the righthand plate.

The correct calculation in this instance would be to average the number of visible colonies on the duplicate plates and multiply by 10,000.This takes into consideration the 104 dilution.

62 + 60 = 122

122 / 2 = 61

61 x 10,000 = 610,000 cfu/g

Individual counting technique alone can have a significant effect on the final result depending on how the analyst interprets the growth. Incertain cases it may be difficult to count the colonies; small, obstructed or conjoined colonies may be interpreted differently depending onthe analyst. Spreading colonies in the form of chains should be considered as one colony. In a real life scenario the analyst would be able toconduct a more thorough examination at various angles and light conditions in order to achieve a more accurate count.


The sample contained Salmonella Nottingham at an approximate level of 11 cfu/375g. The assigned value is therefore Salmonella species‘detected’.

Salmonella Nottingham is characteristic of the genus on selective media and in confirmatory tests, being H2S positive, motile, lactosenegative, citrate positive and urease negative. It is a group I Salmonella according to the Kauffmann-White Scheme, with a full serologicalprofile of ‘O’ antigen: 16; ‘H’ phase 1 antigen: d and ‘H’ phase 2 antigen: e, n, z15.

Salmonellae are Gram-negative non-spore forming rods that are oxidase negative and catalase positive, and are members of theEnterobacteriaceae family. Almost all Salmonella serotypes cause acute gastro-enteritis and account for a large proportion of all foodpoisoning outbreaks. Primary sources of Salmonellae are the gastrointestinal tract of animals; the organism can be transmitted via faecesinto soil, water, feeds, foods and other animals, including humans.
