GMP Chemistry Laboratory

This lab will be closed from mid-afternoon on Friday 22 December 2023, reopening on Monday 8 January 2024. Samples will be accepted over the holiday period, but turnaround times will be extended due to the closure.

Food Chemistry Laboratory (including Trace Metals)

This lab will be working with a skeleton staff for non-statutory days and closed at weekends.

Natural Toxins Laboratories

The biotoxin and phytoplankton labs will be open on the non-statutory days and closed on the weekends. On open days, samples need to be received at the lab before 10am to ensure they are processed that day. Phytoplankton results will be reported the same day and biotoxin results reported the following day. Samples received after 10am for biotoxin testing will be added to the next run.

Shellfish samples received Friday (29 December and 5 January) may have to be reported the following week, dependent on the sample numbers received. To increase the chances of having results reported before the weekend, please send samples to the lab as early in the week as possible.

Courier Services

If you plan to send us perishable/time sensitive samples for testing, we recommend the following cut off dates to ensure delivery:
Prior to Christmas: Thursday 21 December 2023
Prior to New Year: Thursday 28 December 2023

Full laboratory services will resume from Monday 8 January 2024.
