MicroVal certified an extension study for the Bentley Instruments BactoCount IBC 3.0 & BactoCount IBCm 3.0 devices. These devices measure total bacterial count (TBC) and somatic cell count (SCC). Initially validated in 2022 for raw cow’s milk, they are now certified for raw goat’s and sheep’s milk as well. Both validation studies were conducted by ACTALIA Cecalait.
The BactoCount IBC 3.0 & BactoCount IBCm 3.0 can offer simultaneous real-time analysis of TBC and SCC in raw milk with a flow cytometer, but in the frame of this validation, TBC and SCC were tested separately. The validation scope covers only the separate use of TBC and SCC.
The extension studies were done according to ISO 16297, ISO 21187, and ISO 16140-2 for TBC and according to ISO 8196-3, ISO 13366-2, and ISO 16140-2 for SCC, using ISO 4833-1 and ISO 133366-1 as reference methods. Results obtained for TBC were also compared with the limits defined in the EU-RL document. The programs used to analyze sheep’s and goat’s milk are the same as for cow milk (ratio milk/reagent, type of reagent, incubation time, and protocol).
Both certificates 2021LR97 and 2021LR98 can be found on our website.
