Targeted food pathogen testing

Define the organism, food matrix and portion needed for the testing purpose.

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.
