8.7 Samples for Analysis - Transport and storage of samples
Final parts of food which are perishable must be kept refrigerated or in a frozen state, as necessary. The method of storage used will differ, depending on whether the final part is to be submitted to the Public Analyst, or retained for possible submission to the Laboratory of the Government Chemist.
The final part to be submitted to the Public Analyst must be transmitted as soon as practicable after sampling, particularly where tests are to be made for substances which might deteriorate or change with time (e.g. certain pesticides, sulphur dioxide, etc). In any case, where doubt exists about suitable storage or transport arrangements for samples for analysis, the Public Analyst must be consulted. Since retained final parts might need to be stored for several months prior to submission to the Laboratory of the Government Chemist, it is important that they are appropriately stored.
