Understanding the Sampling Plan (n, c, m, M)
Microbiological specifications are often presented using four parameters: n, c, m, and M. These values are part of internationally recognized sampling plans used in food safety management.
| Parameter | Meaning |
|---|---|
| n | Number of sample units tested from a batch |
| c | Maximum number of samples permitted to fall between m and M |
| m | Acceptable microbiological level |
| M | Maximum allowable level before the batch is considered unsatisfactory |
This statistical approach provides a more representative assessment of batch quality than testing a single sample alone and supports consistent decision-making during product release.
