Before preparing the shipment
Describe the food, testing scope, number of samples and planned use of the results. We establish the sample quantity, containers and delivery conditions around the work.
Identify every unit
Label the product code, version, lot, production date and storage condition. Keep different lots and formulations separate. For shelf-life work, identify the exact retail package being studied.
Send representative material
The sample should represent the product and stage the report is intended to describe. Keep unopened units intact where required and follow the agreed temperature and handling plan.
Coordinate timing
Plan delivery before collection or production where microbiology or study setup makes timing important. Contact the laboratory about delays or package damage so their effect can be reviewed.
