Is Costco Manuka Honey Real or Fake? A Definitive Guide to Authentic Nutrition

4 min read

According to the UMF™ Honey Association, up to 80% of honey labelled as Manuka may not be legitimate. This alarming statistic raises a critical question for consumers interested in high-quality products: is Costco Manuka honey real or fake? The answer lies in understanding the specific certifications that guarantee authenticity and examining the labels closely.

Quick Summary

Authenticity of Manuka honey at Costco is verified by specific UMF™ and MGO ratings, which signal independent testing for key chemical markers. The retailer stocks genuine, certified products from reputable New Zealand brands like Manuka Health and Comvita, not a private-label Kirkland Manuka.

Key Points

  • Check Certifications: Authentic Manuka honey from Costco will carry the UMF™ trademark or a specific MGO rating on its label, indicating independent quality testing.

  • New Zealand Origin: True Manuka honey is exclusively from New Zealand; certified products sold at Costco explicitly state this on the label.

  • Trusted Brands: Costco offers Manuka honey from reputable New Zealand producers like Comvita and Manuka Health, not a private-label Kirkland Manuka product.

  • Higher Ratings Matter: For greater potency, look for higher UMF™ and MGO numbers, such as UMF 20+ (MGO 850+), which indicate higher concentrations of active compounds.

  • Beware of Unregulated Terms: Uncertified products or those using vague terms like "Active Manuka" may be fraudulent and should be avoided.

  • Traceability is Key: Legitimate Manuka honey, including that sold at Costco, is traceable from the beekeeper to the jar, ensuring its authenticity.

The Rise of Manuka Honey and the Problem of Counterfeits

Manuka honey, a premium honey from New Zealand, has gained significant popularity worldwide for its purported health benefits, which are attributed to its unique antibacterial properties. However, this popularity has led to widespread food fraud, with a large percentage of products marketed as Manuka not being authentic. Consumers, therefore, must be vigilant and know what to look for when purchasing. When buying high-end products like Manuka, finding a trustworthy source is crucial. This is where big-box retailers like Costco enter the conversation. The question of whether their Manuka honey is genuine is a common concern among health-conscious shoppers looking for both quality and value.

Understanding Manuka Honey Certification

The key to unlocking the mystery of Manuka authenticity is understanding the certification systems. For a product to be considered genuine Manuka honey, it must originate from New Zealand and meet strict quality standards. The two most recognized certification systems are UMF™ and MGO.

The UMF™ (Unique Manuka Factor) System

Developed by the Unique Manuka Factor Honey Association (UMFHA), UMF™ is a comprehensive quality trademark and rating system. It tests for four key markers to guarantee the honey's quality and authenticity:

  • Leptosperin: A unique compound found only in Manuka nectar, verifying authenticity.
  • Dihydroxyacetone (DHA): Converts into MGO over time and indicates freshness.
  • Methylglyoxal (MGO): The key antibacterial compound.
  • Hydroxymethylfurfural (HMF): Checks for overheating or aging.

To be certified UMF™, honey must be independently tested and must carry the UMF™ trademark, along with the UMFHA member's license number, on the label.

The MGO Rating System

The MGO system measures only the concentration of Methylglyoxal in milligrams per kilogram (mg/kg). While a higher MGO number indicates greater antibacterial strength, it is a less comprehensive measure than the UMF™ rating, which checks for multiple unique chemical markers. Authentic Manuka honey will often list both its UMF™ grade and corresponding MGO level.

Is Costco Manuka Honey Real or Fake? The Verdict

Based on product listings and customer reviews, Costco does sell real Manuka honey, but it's important to be specific about which products you're evaluating. Costco's strategy is to offer certified, authentic products from established, reputable brands rather than creating a private-label Kirkland Manuka honey. The search results show Costco carrying Manuka products from trusted New Zealand brands like Manuka Health and Comvita.

These products clearly display their UMF™ and MGO certifications on the packaging, indicating that they have undergone the rigorous testing process required by New Zealand authorities and independent associations. The product descriptions on Costco's website confirm their origin in New Zealand, their raw and unpasteurized status, and the certification for specific MGO and UMF™ levels. Customer reviews for these specific products are generally very positive, with many users confirming its quality and effects.

Authenticity Checklist for Costco Manuka Honey:

  • UMF™ Trademark and License Number: Look for the UMF™ logo on the label, which indicates independent testing and certification.
  • Clear MGO Rating: The Methylglyoxal level should be clearly stated in mg/kg.
  • New Zealand Origin: Ensure the label explicitly states the honey is a "Product of New Zealand".
  • Traceability: Legitimate brands often provide a batch number or QR code for traceability back to its origin.
  • Reputable Brand: Purchase brands like Comvita or Manuka Health, which are pioneers in the Manuka honey market.

How to Avoid Counterfeit Manuka Honey

While Costco's stock is generally reliable, vigilance is key when purchasing Manuka honey from any retailer. Here are some red flags to watch for:

  • Lack of Certification: Products that claim to be Manuka but have no UMF™ or MGO rating should be avoided. Avoid vague terms like "Active Manuka," which are not regulated.
  • Suspiciously Low Price: Genuine Manuka honey is an expensive, specialty item. If the price is too good to be true, it likely is.
  • Incorrect Origin: Manuka honey must come from the Manuka tree in New Zealand. Check the country of origin on the label.
  • Poor Labeling: Look for professionalism and clear information. Inconsistent labeling or a lack of detail can be a warning sign.

Purity Independently tested to meet NZ standards Purity is not verified; may be adulterated
Price Premium and reflective of quality Often suspiciously low
Traceability Protected and traceable from beekeeper to jar Origin is often obscured or untraceable

Conclusion: Making a Confident Purchase

Frequently Asked Questions

No, Costco's Kirkland Signature honey is not the same as Manuka honey. The Kirkland brand offers raw, unfiltered honey sourced from regions like Florida or Argentina, while the genuine Manuka honey sold at Costco is from New Zealand brands like Manuka Health and Comvita.

To check for authenticity, look for the UMF™ logo and a valid MGO rating (e.g., MGO 850+) on the label. The product should also state that it is a "Product of New Zealand." You can use the batch number to verify its origin with the producer.

The UMF™ rating is a comprehensive system that measures multiple key chemical markers, including MGO, DHA, and Leptosperin, to guarantee authenticity and quality. The MGO rating only measures the concentration of Methylglyoxal, the main antibacterial compound.

Manuka honey is expensive because its production is limited to a short flowering season of the Manuka bush in remote areas of New Zealand. The high-potency and certified products require extensive independent testing, adding to the cost.

No, Costco sells Manuka honey in different grades. The search results show online listings for high grades like UMF 20+ (MGO 850+) as well as lower grades that may be available in stores, each with different potency levels and price points.

No, at-home tests like the 'thumb test' or 'water test' are not reliable for determining genuine Manuka honey. The only accurate method is laboratory testing for the specific chemical markers, which is why relying on accredited certification logos like UMF™ is crucial.

Traceability is important because it ensures a product's authenticity and origin. Genuine Manuka honey brands, including those at Costco, provide protection and traceability from the beekeeper to the jar, helping to prevent fraud and ensuring quality.
