Tutin

Tutin is a toxic compound found in some honey, where bees have had access to the NZ native Tutu plant (Coriara genus).  After a number of people were hospitalised after eating honey containing Tutin, the Ministry for Primary Industries brought in food safety regulations requiring honey to be tested for Tutin. 

Toxic honey can be produced during the summer if bees collect honeydew secreted by passion vine hopper insects that are feeding on the sap of Tutu plants.  MPI have established a maximum residue level (MRL) of 0.7 mg/kg of tutin in honey to protect people eating honey, and testing of honey produced in many areas of NZ is required before honey is able to be sold.

Analytica has developed a sensitive method for testing honey for tutin, which can be used to test for Tutin in individual or composite samples.  Analytica is approved by MPI to carry out this testing.

When individual samples are tested, Tutin concentration is reported to a detection limit of 0.02 mg/kg.

For composite testing, individual samples are submitted to the laboratory, and up to 10 of these individual samples are carefully combined into a single composite sample for analysis.  The Tutin concentration in the composite sample will identify that either all individual samples in the composite will be below the MRL of 0.7 mg/kg, or that at least one of the samples in the composite is likely to have a concentration of Tutin that is above the MRL of 0.7 mg/kg.  If a composite sample has a high Tutin result, further testing of the individual samples needs to be done to identify which of them are above the MRL.

This method can be used in all honey types.  It can also be used in comb, liquid, and creamed honey.

How does Analytica conduct the test

Following dilution in water and extraction, the honey sample is analysed for tutin residue using Liquid Chromatograph-Mass Spectrometry (LC-MS/MS).

Accreditations

Tutin is an ISO 17025 and MPI accredited test.

How Much & How Long Will it Take

Test / Price / Turnaround
Tutin (individually tested)
$80.00 per sample
1 - 2 Days
Tutin (composite)*
$80.00 + $10.00 per sample included in the composite
1 - 2 Days

Prices in NZ$ exclusive of GST. We can offer discounts for large batches of samples. Please contact us to discuss. 

Target turnaround time = the number of working days we expect to elapse between when we receive your sample(s), and when we email your test report. Urgent samples - please contact the laboratory as soon as you become aware of a need for urgent testing so that we can make plans with you to help meet your needs. 

Tutin (composite)*
For example, Tutin-4 = a group of 4 samples that Analytica will combine into a single composite sample, and report one result that represents the average tutin value for all 4 samples in that composited group. Price for this example would be $80 + (4x$10) = $120. If the level of tutin found is less than 0.175 mg/kg (that is, less than one quarter of the limit) then it can be assumed that none of the 4 samples is above the limit of 0.7 mg/kg. If a composite sample test indicates that one or more of the samples exceeds the limit, Analytica will phone you to discuss what action you require us to take.


Why Use Analytica?

Analytica have a fast turnaround time and competitive price. Analytica are able to carry out a number of tests on your honey, which means you can send in one sample and let us take care of the rest.



How to take and submit a sample

How to take and submit a sample


Approximately 50g of sample should be taken from a well-mixed, homogenous honey drum and placed in a clean container with a lid.  Samples should not contain wax.

On the form there are two separate columns for individual and composite testing. Please indicate the preferred groups of honey samples for composite testing – no indication will assume groups of 10. Please note that each new composite group costs $80.00 with $10 per sample added.

Don’t forget to label each sample container with a unique name or code, matching the Sample Identification that you write on the Analysis Request Form. We will invoice you when we report your results. 

Please email the Sample Reception team at sample.receipt@analytica.co.nz if you are sending more than 40 samples to make the most of our testing prices and turnaround times.

To send samples from overseas, please see our instructions and import permits.
