How to Check Manuka Honey Authenticity: Labels, Batch Numbers and Laboratory Reports

To check whether Manuka honey is genuine, start by connecting the claims on the jar to the evidence for the honey inside it. Look for clear origin information, an understandable grade, batch identification and relevant laboratory or certification records.

No single number or document answers every authenticity question. The UK Food Standards Agency explains that honey authentication requires a combination of evidence, including appropriate analytical testing and traceability checks, rather than one universal test. (food.blog.gov.uk)

For shoppers, a useful checking sequence is:

Read the label → identify the batch → request relevant evidence → check what the evidence actually demonstrates.

You do not need to become a laboratory scientist. The aim is to ask specific questions and avoid accepting a general statement such as “laboratory tested” as an explanation of everything about the product.

1. Identify exactly what you want to verify

Before asking for a certificate, write down the claim you are checking. These are related but separate questions:

Treat this as a practical question list—not a requirement that every supplier uses the same report format.

A result addressing one question should not automatically be treated as an answer to all five. This is consistent with the broader weight-of-evidence approach used in food-authenticity investigations, which considers information from multiple sources. (gov.uk)

Read the precise origin wording

For Australian products, distinguish between statements about where the honey was produced and where it was packed. The ACCC explains that “produced in,” “made in” and “packed in” have different meanings; a packing location alone does not establish the origin of the food. (accc.gov.au)

For the general label-reading basics, see our guide to how to read an Australian honey label. Here, the next step is to connect those label details to supporting evidence.

2. Find the batch information—not just the barcode

Keep the jar and purchase record while checking the product. Photograph the front label, back label and any codes printed on the lid, base or packaging.

Record the product name, declared grade, jar size, origin statement, date marking and lot or batch information. If a code is unclear, ask the seller which identifier they use to trace the honey.

FSANZ’s traceability guidance identifies batch or lot details, supplier information, transaction dates and production records as important parts of tracing food through the supply chain. (foodstandards.gov.au)

A product barcode and a batch number serve different purposes

A Global Trade Item Number, or GTIN, identifies a type of trade item. Additional information, such as a batch or lot number, identifies a particular production group. Consequently, a barcode identifying the correct honey product is not, by itself, a link to the laboratory report for your batch. (gs1au.org)

The question to ask is:

“Which batch or lot does this jar belong to, and how does that connect to the supporting test information?”

This avoids a common dead end: finding the correct product online but still not knowing whether the evidence applies to the honey supplied.

3. Request the relevant report

Instead of asking only “Do you have a certificate?”, ask:

“Can you provide or explain the test information supporting the grade and origin of the batch currently being supplied?”

Request the complete relevant report where it can be shared, rather than a cropped screenshot showing only a favourable number. If a summary is supplied instead, ask who issued it and how it relates to the original laboratory results.

Use the following reading checklist. It is a practical review aid, not a claim that every laboratory uses an identical layout.

Do not assume that a different sample code automatically proves something is wrong. Instead, ask for the missing connection.

For example, a report might identify a bulk sample while the jar carries a packing-lot code. The supplier should be able to explain the relationship. That request follows the traceability principle of connecting inputs, production records and supplied products. (foodstandards.gov.au)

4. Check the laboratory and the report’s status

A laboratory name or accreditation logo deserves a closer look.

Where accreditation is claimed, check the laboratory’s official accreditation listing and whether the relevant activity is covered. NATA explains that endorsement relates to activities within an organisation’s accreditation scope—not every possible test that organisation might offer. (nata.com.au)

This matters because “the laboratory is accredited” and “this particular test is covered by its accreditation” are not necessarily the same statement.

If something looks inconsistent, contact the laboratory using contact details obtained independently from its official website. Ask what it can verify about the report number and document; the laboratory may need its client’s permission before sharing confidential information.

Is it preliminary or final?

Check whether the document is marked preliminary, amended or superseded. NATA’s reporting guidance distinguishes preliminary reports and sets out how changes and replacement reports should be identified. (nata.com.au)

For your review, ask for the applicable final version. Avoid interpreting a screenshot without its surrounding notes or assuming that an older copy remains the current report.

5. Understand what the tests measure

Manuka reports may contain several results that answer different questions. More numbers do not necessarily mean you have read a complete authenticity assessment.

For example, ALS Food & Environmental NZ’s published Manuka 3-in-1 method measures MGO, DHA and HMF. It also reports a calculated NPA value derived from the MGO result. This illustrates why it is important to distinguish a direct measurement from a calculated value. (analytica.co.nz)

MGO: compare the concentration with the stated grade

An MGO grade describes methylglyoxal concentration in milligrams per kilogram. A label such as MGO 500+ declares at least 500 mg/kg. It is not a flavour score, country-of-origin certificate or medical recommendation. (australianhoneycompany.com.au)

Our MGO 500+ Australian Manuka honey is an example of a product labelled using that concentration-based grading approach. The product description is the claim being evaluated; it should not be confused with an independent laboratory report. (australianhoneycompany.com.au)

For more detail about the units, read what MGO means in Manuka honey.

Floral identity requires its own evidence

New Zealand’s MPI framework for honey exported as mānuka combines four chemical attributes and one DNA marker. It distinguishes qualifying monofloral and multifloral mānuka; it does not authenticate the honey through an MGO result alone. This framework applies to New Zealand mānuka exports, not automatically to Australian honey. (mpi.govt.nz)

Adulteration testing also has limits

A test for added sugars answers a different question from a Manuka grading test. The Food Standards Agency advises considering analytical results alongside traceability and other evidence, particularly where a result is indicative rather than conclusive. (food.blog.gov.uk)

Ask what was tested instead of interpreting the word “passed” as meaning that every possible authenticity, quality and safety question has been resolved.

6. A worked example: the number is not the whole check

The following identifiers and result are fictional. They are not a laboratory report for Australian Honey Company products.

Suppose you are reviewing this information:

The number 540 is above 500, but the review is not finished.

First, ask how DEMO-BULK-07 connects to DEMO-JAR-01. Then ask whether the tested sample represents the honey actually packed, including whether anything happened between sampling and packing that affects the relevance of the result.

Even with a documented connection, that single value addresses the measured MGO concentration—not every question about origin, floral identity or adulteration.

The useful conclusion is therefore:

“The reported concentration is numerically above the declared threshold. I still need the batch connection and the report’s applicable qualifications before relying on it for this jar.”

For borderline results, request the laboratory’s interpretation rather than deciding solely from the last digit. Laboratory guidance explains that sampling and measurement variation can affect results, especially near a specification limit. (analytica.co.nz)

7. Check dates and separate measurements from forecasts

A test result describes the tested sample at a particular time. A forecast estimates what may happen under stated conditions.

The published Manuka 3-in-1 guidance explains that results can change over time and distinguishes measured results from forecasts of future MGO and related values under different storage conditions. (analytica.co.nz)

Therefore, do not treat “forecast to reach MGO 1000” as equivalent to “measured at MGO 1000.”

Ask which figure is an actual result, which is a prediction, and how the supplier supports the grade of the product being sold.

For example, when considering an MGO 1000+ Manuka product, the relevant question concerns evidence supporting that advertised grade—not merely the possibility that a different sample might reach it later.

A report’s age alone is not enough to decide whether it is relevant. Look at the batch relationship, sampling stage, storage information and any subsequent assessment together.

8. Verify certification claims within the named scheme

Certification can provide useful additional assurance, but check the scheme actually claimed.

Do not assume a product is fraudulent because it lacks one particular voluntary mark. Equally, do not assume it has passed a scheme’s requirements when it does not claim participation.

A useful follow-up question is:

“Which organisation issued this certification, and how can I verify that it applies to this product?”

9. Do not replace evidence with home demonstrations

Do not use water, flame, thumb or paper demonstrations to certify Manuka identity or assign an MGO grade. None gives you a batch-linked laboratory measurement or verifies a certification licence.

This follows from the more fundamental limitation highlighted by the Food Standards Agency: honey authenticity is complex and cannot be settled by one universal test. A household demonstration should not be treated as stronger evidence than a properly interpreted combination of testing and traceability. (food.blog.gov.uk)

Likewise, avoid declaring a product genuine solely because it is expensive, dark, thick or attractively packaged.

For questions about changing texture, read our guide to honey crystallisation, but keep texture observations separate from the authenticity review.

What to ask the seller

A short, specific enquiry is usually more useful than requesting every document the business holds:

Hello, I’m considering your Manuka honey labelled [grade]. Could you confirm the batch currently being supplied and explain which test information supports that grade and the stated origin?

If the laboratory sample code differs from the jar’s lot code, please explain the connection. Please also identify any certification claimed for this product.

If the response leaves a material question unanswered, ask for clarification before making the purchase. Missing information is a reason to investigate—not, by itself, proof of fraud.

Common questions

Does every jar need its own laboratory report?

The practical question is whether the tested sample appropriately represents the batch containing your jar. A report shared across jars needs a clear batch connection; do not assume that a report for one sample supports an entire brand indefinitely.

FSANZ’s traceability guidance emphasises linking products, inputs, batches and supply records, which is the connection to ask the supplier to explain. (foodstandards.gov.au)

Does a QR code prove authenticity?

Treat it as a route to information, not proof on its own. Check where it leads and whether the result identifies the relevant product, batch, issuing organisation and evidence. A link to a generic homepage does not answer those questions.

What should I do if the seller’s explanation and report disagree?

Keep the jar, receipt, report and correspondence. Ask the seller to resolve the specific discrepancy in writing. Where technical interpretation is needed, seek clarification from the issuing laboratory rather than trying to infer the answer from an isolated result.

The bottom line

The most useful authenticity check connects the label, the batch and the evidence.

Understand the claim, identify the honey supplied and check what the relevant report or certification actually supports. Treat an MGO result as a measurement—not an automatic answer to every question about the product.

When browsing our Australian Manuka honey range, review the product information and contact Australian Honey Company about any details you need clarified before ordering.

Choose clear, relevant evidence over a reassuring slogan—and ask whether that evidence applies to the honey in your jar.
