Honey is a common target for food fraudsters<\/figcaption><\/p>\n<\/figure>\n<\/div>\n
\n

Food crime mostly goes unreported, so it’s difficult to grasp its scale.<\/p>\n<\/div>\n

\n

It can include diluting or substituting ingredients, altering documents, or going through unapproved processes.<\/p>\n<\/div>\n

\n

One 2025 estimate is that food crime costs the global economy around \u00a381bn ($110bn) a year.<\/p>\n<\/div>\n

\n

Fraudsters tend to target commonly consumed foods, like dairy, and high-value foods, like olive oil.<\/p>\n<\/div>\n

\n

Along with alcohol, seafood and edible oils, honey is frequently among the most common foods that are faked.<\/p>\n<\/div>\n

\n

Plant-based syrup, such as glucose syrup derived from sugar cane, can be half the price of genuine honey, or even less.<\/p>\n<\/div>\n

\n

In addition to keeping five beehives, Dr Juraj Majt\u00e1n heads a lab studying bees and bee products at the Institute of Molecular Biology, part of the Slovak Academy of Sciences.<\/p>\n<\/div>\n

\n

He understands well just how biologically complex honey is. It contains hundreds of compounds, and there are many diverse types and sources of honey.<\/p>\n<\/div>\n

\n

One result is that it’s challenging to detect whether the honey in a jar genuinely comes from honeybees from a particular place, or has been mixed with syrup derived from rice, wheat, corn or sugar beets.<\/p>\n<\/div>\n

\n

There isn’t even an internationally agreed definition of honey.<\/p>\n<\/div>\n

\n

While fake honey is sometimes runnier and weaker-tasting than genuine honey, sophisticated fakes can look, smell and taste just like the real thing. Inauthentic honey can also fool chemical analysis, because the sugar levels are so similar.<\/p>\n<\/div>\n

\n

There are a variety of methods to test for suspicious honey.<\/p>\n<\/div>\n

\n

Some analyse chemical bonds to compare them against genuine honey samples. Others analyse isotopes to determine where a product likely originated.<\/p>\n<\/div>\n

\n

But “currently there is no single method\u2026that can say that this honey is fake honey,” Dr Majt\u00e1n explains. He says that we desperately need new methods.<\/p>\n<\/div>\n

New methods are needed to spot fake honey says Dr Juraj Majt\u00e1n<\/figcaption><\/p>\n<\/figure>\n<\/div>\n
\n

The harms from faked honey are mostly to the livelihoods of beekeepers.<\/p>\n<\/div>\n

\n

But food crimes can pose dangers to human health, because of the presence of potential allergens or toxic chemicals.<\/p>\n<\/div>\n

\n

Back in 2008, Dr Selvarani Elahi was caring for her newborn daughter while growing horrified about the scandal of melamine-tainted infant formula in China. At least six babies died from kidney damage linked to the chemical.<\/p>\n<\/div>\n

\n

Elahi, the UK’s deputy government chemist, who is based at the measurement and testing services company LGC, couldn’t believe that food fraudsters would target children.<\/p>\n<\/div>\n

\n

Two people involved in the contamination were executed.<\/p>\n<\/div>\n

\n

“Even the risk of that doesn’t stop people from perpetrating fraud,” Elahi marvelled.<\/p>\n<\/div>\n

\n

Now, with several decades of food-standards work under her belt, Elahi remains alert to the possibility of fraud infiltrating other types of foods.<\/p>\n<\/div>\n

\n

For instance, LGC is advising the UK government and working on DNA methods to identify foods containing the four insect species allowed for sale for human consumption.<\/p>\n<\/div>\n

\n

Fraudsters could theoretically attempt to pass off a different insect species as one of those four.<\/p>\n<\/div>\n

\n

One potential consequence is that an unpermitted insect species could trigger reactions in people allergic to shellfish, which can have the same allergenic proteins.<\/p>\n<\/div>\n

Even the risk of hurting children does not stop fraudsters says Dr Selvarani Elahi<\/figcaption><\/p>\n<\/figure>\n<\/div>\n
\n

While insects are a novel food in some countries, tainted spices are a persistent global problem. For instance, fraudsters add widely available industrial dyes to paprika.<\/p>\n<\/div>\n

\n

Especially notorious is lead chromate mixed in with cinnamon to achieve a bright colour or bulk out the powders.<\/p>\n<\/div>\n

\n

In the US in 2023, hundreds of children were poisoned by lead from imported cinnamon that made its way into applesauce.<\/p>\n<\/div>\n

\n

The technological methods to detect industrial dyes in spices aren’t the issue, according to Elahi. These are robust enough to detect the synthetic dyes at low levels.<\/p>\n<\/div>\n

\n

The problem is spotty surveillance by under-resourced regulators.<\/p>\n<\/div>\n

\n

For Dr Karen Everstine, lead in cinnamon shows the importance of not only regulatory agencies but also a well-functioning public health system, “to help support food safety and detect anomalies”.<\/p>\n<\/div>\n

\n

Everstine is the technical director of food safety solutions at FoodChain ID, a company that advises food-sector clients.<\/p>\n<\/div>\n

\n

FoodChain ID commonly observes fraud that involves swapping out one species for another.<\/p>\n<\/div>\n

\n

In 2025, their data also showed a slight increase in labelling fraud, such as olive oil labelled falsely as being extra virgin, or non-organic crops marked as organic.<\/p>\n<\/div>\n

\n

For 2026, she’s especially concerned about trendy superfoods and supplement-like foods. False claims on these foods can be especially hard to combat because they become crazes so quickly on social media.<\/p>\n<\/div>\n

\n

Ultimately, the most rigorous traceability solutions, including QR codes and microchips, won’t be useful if people don’t actually check them as a condition of making their purchases. Imitators can simply counterfeit QR code labels, for example.<\/p>\n<\/div>\n

\n

Nor will they be useful if they remain too expensive to implement.<\/p>\n<\/div>\n

\n

“People thought blockchain applied to the food industry was going to solve all of our problems. It hasn’t,” notes Elahi.<\/p>\n<\/div>\n

\n

She points out that blockchain-based tracking of a food at each point in the supply chain might be feasible for a product like South American bananas, but isn’t feasible for a lasagne containing 50 ingredients from all over the world.<\/p>\n<\/div>\n

\n

It can also be hard to interpret the results of testing finished products that contain lots of ingredients.<\/p>\n<\/div>\n

\n

“One of the challenges is marrying that really high-technology, high-innovation space with the realities of food production,” Everstine comments. It’s just not practical to test everything.<\/p>\n<\/div>\n

\n

Innovations in recent years to make testing methods more sophisticated include thermal imaging, light analysis using lasers, and DNA profiling.<\/p>\n<\/div>\n

\n

In general, more testing adds to the costs. And lab-based testing may not be fast or agile enough to support border control officers, fraud investigators or food producers in the field.<\/p>\n<\/div>\n

\n

Speed is important when seeking to stop the spread of tainted foods. Yet rapid testing tools may not be sensitive enough.<\/p>\n<\/div>\n

\n

Emerging portable testing methods include X-ray fluorescence analysers for turmeric and handheld DNA kits to test olive oil.<\/p>\n<\/div>\n

\n

Machine learning is also increasingly helpful for sifting through and categorising huge amounts of data. This can help to create early warnings about risks of fraudulent or unsafe food.<\/p>\n<\/div>\n

\n

Still, relatively low-tech responses to food crime are among the most useful.<\/p>\n<\/div>\n

\n

With honey, Majt\u00e1n says, “the best way is just to buy from local beekeepers”. This helps ensure that consumers know what they’re buying, and who they’re supporting.<\/p>\n<\/div>\n

\n

One rule of thumb Everstine has is that “if the price seems too good to be true, that should be a red flag”. For instance, $3 for a bottle of olive oil or honey in the US might be suspect.<\/p>\n<\/div>\n
