What is ISO 16297 about?
ISO 16297 specifies a protocol for the evaluation of instrumental alternative methods for the total bacterial count in raw milk from animals of different species.
Note: The document is complementary to ISO 16140‑2 and ISO 8196 | IDF 128 (all parts).
Who is ISO 16297 for?
ISO 16297 on the bacterial count in milk is useful for:
- Food technologists
- Chemical Engineers
- Food and safety department
- Milk Farms and dairy centres
Why should you use ISO 16297?
The bacterial count of a substance is a quantitative estimate of the number of microorganisms present in a sample.
ISO 16297 provides methods and procedures for determining bacterial count in milk and provides general measurement protocols and standard methods to determine how samples should be rated based on the results.
ISO 16297 provides the milk processors with measures to keep the accuracy of the estimates to achieve better results.
As a whole, ISO 16297 is a comprehensive set of procedures for testing, calculating, preparing test samples, and determining the bacterial count in milk, which will facilitate the standardization of milk quality without negatively impacting its health value.
What’s changed since the last update?
BS EN ISO 16297:2020 supersedes BS EN ISO 16297:2014. BS EN ISO 16297:2020 includes some technical changes concerning BS EN ISO 16297:2014. These include:
- The number of samples and the calculation of the lower limit of quantification has been changed and aligned with ISO 16140‑2;
- An example of carry-over effect given in Figure 1 has been omitted;
- The requirements for the evaluation of the accuracy of the estimate and the accuracy profile have been clarified and aligned with ISO 16140‑2;
- Annex A (informative) has been omitted.
