1 In the context of compliance control, it is
advisable to maintain chain of custody records for the samples collected.
2 Information to be included should contain a
complete record of those handling the sample from the time of the
sampling onwards.
3 The chain of custody should also include date,
ship identification, sample identification code, and a list of people
who have handled the sample, including the person who takes the sample,
dates and time, and the reason for sample transfer and the integrity
of the sample on transfer.
