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 Tutin in honey, which can be used to test samples individual or as part of a composite.  Analytica is approved by MPI to carry out this testing.

Tutin Individual:
Samples are individually prepared and analysed and the Tutin concentration is reported to the detection limit of 0.01 mg/kg.

Tutin Composite (for up to 10 samples)
Individual samples are carefully combined (by the laboratory) into a single composite sample for analysis. The average Tutin concentration of all samples in the composite is reported. This analysis 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.

It’s important to note that MPI Regulations (Tutin Compliance Guide) state that composite samples must be created by a laboratory. Any composite samples created outside of the laboratory cannot be tested. 

This method can be used in all honey types incl. liquid and creamed honey. For information on testing Tutin in Comb Honey, please refer out Technical Note on Tutin Testing.  

You can read more about Tutin testing in our News & Resources here: Tutin Testing

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).


Tutin is an IANZ and MPI RLP accredited test.

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.

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. 

Download and complete our Analysis Request Form either in PDF format or as a Word document, and send it along with your samples to:

On the form there are two separate columns for individual and composite tutin testing. Please indicate the preferred groups of honey samples for composite testing – if these are not indicated your testing may be delayed while we clarify this with you. 


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