Dear milagr,

A few of the possible related factors –

Sampling what (risk) type of product ?
Sampling for what bacterium ?
Sampling for any particular regulatory standard ?

ie. more info needed please. :smile:

One classic on-line source is USA / BAM. Another is ICMSF. There are many others for different localities.

Some practical UK examples for RTE products –
