Name the target
Request the particular organism or group needed by the project. Salmonella, Listeria monocytogenes and pathogenic E. coli are different analytical targets, not one universal pathogen test.
Describe the matrix
Raw ingredients, ready-to-eat foods and beverages may need different preparation. Tell us the product, processing stage and any characteristics that could affect recovery.
Agree the sample plan
The units and portion tested determine what the finding describes. Keep any compositing approach explicit and agreed in advance.
Plan the response
Know who will review a detected result and which production or lot records will be used for follow-up. A not-detected finding is limited to the target and tested portion.
