Foodproof® Salmonella spp. method renewed and extended for lyophilized kit

MicroVal has approved the renewal and extension of the certificates for the foodproof® Salmonella spp. method, manufactured by BIOTECON Diagnostics for the qualitative detection of Salmonella spp. in foods, feed and primary production samples.

The foodproof® Salmonella spp. method was first validated in 2013 with an automated (certificate 2011LR40) and a manual sample preparation protocol (certificate 2011LR42).  Within the renewal study, the certificates were extended for the lyophilized version of the kit – the foodproof® Salmonella Detection LyoKit. The study was performed by ADRIA Développement, France.

The method is also PTM approved by the AOAC-RI and NordVal validated.

The certificates can be found here on the MicroVal website, together with the supporting summary reports.

Compact Dry TC certificate renewed

MicroVal has approved the renewal of the certificate for Compact Dry TC, manufactured by Nissui Pharmaceutical Co. Ltd and Supplied by HyServe GmbH. Compact Dry TC enumerates total viable organisms in a broad range of foods.

We are proud that the first ever MicroVal certificate to be issued will be valid for at least another four years. Compact Dry TC was first validated twelve years ago in 2007. The renewal study was performed by Campden BRI.

The method is also validated for AOAC PTM and NordVal.

The certificate has number 2007LR01 and can be found here on the MicroVal website, together with the supporting  summary report.

First Semi-Quantitative Certification for Neogen’s Soleris System for Detection of Enterobacteriaceae in Dairy Products

MicroVal has just issued the first certificate for Neogen’s Soleris Enterobacteriaceae, based on a semi-quantitative validation for detection of Enterobacteriaceae at a threshold of <10cfu/ml. The study was conducted by Campden BRI.

This novel approach was designed to meet a specific legislative requirement in EU 2073 for the presence of Enterobacteriaceae in dairy products at a level of <10cfu/ml. Historically, ISO 16140-2:2016 validation studies have either been quantitative i.e. based on enumeration of microorganisms in the test samples, or qualitative, i.e. based on detecting the presence or absence of a target microorganism in a test sample. This semi-quantitative study design compared the results from the enrichment of a test sample in the Neogen Soleris system using the S2-EBAC9 Enterobacteriaceae vial with the results from the reference method which uses a plating method. The unique part of this validation was the use of a single plate of the reference agar where the absence of any colonies was equivalent to detection of <10cfu/ml and the presence of one or more colonies was equivalent to detection of >10cfu/ml. Hence the approach used a plate count method as a qualitative result and not a quantitative result.

This semi-quantitative approach could have a wide application to many other microbiological test methods which use a dilute to specification approach to show compliance with a target threshold of,  for example,  <10cfu/ml  or  <100cfu/ml.

The certificate for Neogen’s Soleris Enterobacteriaceae can be found by the number 2018LR83.

MicroVal’s first certificate within scope of water

In September 2019 MicroVal has approved the issuing of the certificate for HyServe’s Compact Dry PA, the ready to use plate for enumeration of total Pseudomonas aeruginosa (PA). This is the first MicroVal certificate for a enumeration method to be used within the field of water intended for human consumption. The certificate is based on the results of a validation study in accordance with ISO 17994:2014 and ISO 16140-2:2016, which has been performed by Campden BRI. The certificate can be found by the number 2017LR66. The Compact Dry plates are manufactured by Nissui Pharmaceutical CoLtd and supplied by HyServe.

Moreover, the certificate for HyServe’s CompactDry YM for the enumeration of yeasts and moulds in a broad range of foods, which was originally issued in 2011, has been successfully renewed, based on the validation study according to ISO 16140-2:2016 by Campden BRI. The certificate has number RQA2008LR10.

New BioControl Assurance GDS certificate issued

MicroVal has approved the issuing of the certificate for a method by Biocontrol Systems, Inc. The Assurance GDS® Cronobacter Tq II for the detection of Cronobacter spp. in infant formula, infant cereals and environmental samples has been certified, based on the results of the validation study performed by Q laboratories. The certificate has number 2017LR77.

First MicroVal certificate for method by 3M Food Safety

MicroVal has approved the issuing of the certificate for a method by 3MTM Food Safety. The Petrifilm™ Rapid E. Coli Coliform Count (REC) for the enumeration of E. coli and coliforms in a broad range of foods has been certified, based on the results of the validation study performed by Q laboratories. The certificate has number 2017LR76.

First MicroVal certificate issued for Charm Sciences’ method

MicroVal has approved the issuing of the certificate for the method by Charm Sciences, Inc. The Peelplate® EB for the detection and enumeration of Enterobacteriaceae in heat processed milk and dairy products, infant formula and infant cereal, has been certified based on the results of the validation study by Q laboratories. The certificate can be found by the number 2017LR69.

Two new MC-Media Pad certificates issued

In December 2018 MicroVal approved the issuing of two certificates for two MC-Media pad methods developed by JNC Corporation. The MC-Media pad CCTM for the enumeration of coliforms in foods and the MC-Media pad ECTM for the enumeration of coliforms and Escherichia coli in foods were both certified based on the results of a validation study by Campden BRI. The certificates have number 2017LR70 and 2017LR71.

Two SY-LAB certificates issued

Two  SY-LAB certificates issued

In December MicroVal approved the issuing of two certificates for methods developed by SY-LAB Geräte GmbH. The RiboFlow® Listeria Twin Testkit for the detection of Listeria Monocytogenes and Listeria spp was certified based on the results of a validation study by RIVM. Campden BRI performed the validation study for AMP-6000® TMAC for the enumeration of Total Aerobic Mesophilic Count. The certificates have number 2015LR53 and 2015LR60.

Successful workshop confirmation methods

On 29 October 2018, MicroVal organised a successful workshop on the validation and verification of alternative microbiological confirmation methods.

Recently MicroVal approved on the issuing of the first validation certificates for confirmation methods worldwide, for the Bruker Maldi-Tof. These have been issued based on the results of four parallel validation studies for four different target organisms (Cronobacter spp, Samonella spp, Campylobacter and Listeria spp. & Listeria Monocytogenes).

The objectives of the workshop were to inform and exchange on verification and validation of microbiological methods, especially focussing on alternative confirmation methods. The current developments of the relevant standards on validation of alternative microbiological confirmation methods (ISO/DIS 16140-6), on in-house method validation (ISO/DIS 16140- 4) and  verification (ISO/DIS 16140-3) were also discussed.

It was a successful workshop with a full auditorium and lively participation. MicroVal aims to organize more workshops in the future.
