Best Practices in Setting Up Food Fraud Programs

In 2016, the food authenticity team at Queen’s University Belfast published a study that evaluated adulteration levels in oregano—specifically, 78 samples purchased at retail.1 Almost a quarter of the samples had some adulteration. Some samples actually contained more than 70% other leaf material, primarily olive and myrtle leaves. This study was widely reported and appeared to result in drastic decreases in the levels of adulteration in oregano.

However, just last year, the Joint Research Centre of the European Commission published the results of a coordinated control plan for “fraudulent practices” in spices in which they tested 1,885 samples of 6 herbs and spices submitted from from 23 countries.2 Almost half of the 295 oregano samples were “suspicious of being adulterated.” The results of these studies imply that food fraud—especially fraud involving higher-value and further-processed products with a substance that does not make consumers sick—is a persistent risk and demands a sustained response from industry and regulators.

Evaluating historical data from various sources (the scientific literature, regulatory reports, media reports, etc.) is a critical component of a food fraud prevention program, but it is not enough. A strong program will include an in-depth evaluation of what is known historically about food fraud for relevant raw materials, ongoing monitoring of food safety and fraud notifications, a fraud-focused evaluation of supplier controls, audit and testing programs that include specific anti-fraud measures, and an assessment of situational factors that could increase fraud incentive (geographic, economic, etc.).

The Food Fraud Database has tracked public reports of food fraud for almost 10 years. Many incidents are types of fraud that have occurred repeatedly, as the incident distribution from last year illustrates (see Figure 1). In addition to herb/spice fraud, frequent types of fraud include replacement of honey with sugar syrups; unregulated and counterfeit liquor; wines labeled as a more expensive varietal or with undeclared additives; milk products with added protein or fats from other sources; and fraud related to organic certification or geographic origin. Although these types of fraud appear to be “reasonably foreseeable,” the challenge is that during a time of supply chain stressors—such as the COVID-19 pandemic—risks may evolve quickly as suppliers and supply chain structures change. Re-evaluating food fraud vulnerability in response to changing conditions can be time-consuming, but is important to stay ahead of potential risks.

We frequently work with food manufacturers to develop their food fraud vulnerability assessments. Our experience is that searching and compiling risk data and mapping a set of raw materials to the appropriate data sources for analysis can be the most time-consuming aspects of the project. Since Google searches or other manual processes are not always reliable and efficient, a helpful first step can be finding a data source that compiles and standardizes food safety and fraud data from a wide range of reliable sources. The mapping process then involves identifying each individual ingredient component of the raw materials sourced by the company and linking it to the relevant ingredient name in the data source. It is important to invest this time up front to identify the most appropriate data sources and conduct a thorough mapping process. This ensures food safety and quality assurance staff will be notified of information relevant to their particular supply chains moving forward.

Many quality assurance professionals struggle to fit in food fraud assessments and mitigation plans while managing day-to-day food safety and quality programs. A two-stage process, including an ingredient screen followed by a detailed assessment for potentially high-risk ingredients, can make the process more efficient for companies managing hundreds of raw materials (see Figure 2). Existing food safety testing and auditing programs may also have application to food fraud prevention and should also be documented in a food fraud program. Many food companies find value in outside expert guidance to set up a food fraud program so that food safety and fraud risks aren’t unintentionally missed. The goal of a food fraud program is not to add to the workload of food safety and quality assurance staff, but to enable those staff to identify the most targeted measures that will help ensure food safety, authenticity, and brand protection.

In all of human history, adulteration and fraud followed closely in the footsteps of new products, and herbs, spices and drugs are no exception. Even 2000 years ago, Pliny the Elder described adulteration. In ancient Athens, inspectors monitored the authenticity of wine. Scientific methods were first applied by Archimedes, and started to be utilized more by the end of the 17th century. In the 1850s, heightened public awareness and the demand for higher product quality raised anti-adulteration movements and increased enforcement.

Spices and herbs are sourced at a rate of 300,000 tons into the EU from places around the world, and fraudulent activity can happen in any steps along the supply chain. The European Commission’s control plan investigated nearly 2,000 samples of herbs and spices commonly targeted for fraud, such as oregano, cumin, turmeric, paprika, pepper and saffron, and found oregano to be the most manipulated, usually by the addition of olive leaves. Overall, the rate of 17% fraudulent products was down compared to other studies.

Who wants shredded olive leaves on their pizza instead of oregano? Herbs and spices keep being a target for food fraud, a European Commission study that analyzed nearly 1,900 samples revealed. The study showed that about 20% of herbs and spices are manipulated, with oregano leading the top of the list, followed by spices that include pepper, cumin, curcuma, saffron and paprika. Europe is a leading importer of herbs and spices at 300,000 tons a year. The entire supply chain from country of origin, processing, packaging, importing to distribution, is potentially vulnerable to fraud. In most cases, undeclared plant material was added, and sometimes toxic dyes were found—and these are detrimental to human health.

A Northern Ireland-based analytical lab added white pepper to its portfolio of food authenticity tests based on spectroscopy with chemometric analysis. White pepper, the ripe berries of the piper nigrum plant, is undergoing an additional production step, fetches a higher price than black pepper and therefore is a target for fraudsters. Often, bulking substances like skins, flour, husks and spent materials are used, but in some cases of pepper fraud, the substances used were hazardous to human health.

Spices have been an ongoing hot target for fraudulent activity, whether it is the addition of inedible substances like dyes, or bulking agents, such as brick powder, other plant material, sawdust and many other, potentially hazardous substances. A relatively new technology, next-generation sequencing (NGS), enables to analyze the DNA of complex samples such as spices and herbs. The DNA findings are compared to a database and allow to detect many thousands of species in one test. Currently, working groups are developing standardized methods for such authenticity tests.

Food Authenticity: 2020 in Review

By Karen Everstine, Ph.D.

It is fair to say that 2020 was a challenging year with wide-ranging effects, including significant effects on our ongoing efforts to ensure food integrity and prevent fraud in the food system. COVID-19 caused major supply chain disruptions for foods and many other consumer products. It also highlighted challenges in effective tracking and standardization of food fraud-related data.

Let’s take a look at some of the notable food fraud occurrences in 2020:

  • Organic Products. The Spanish Guardia Civil investigated an organized crime group that sold pistachios with pesticide residues that were fraudulently labeled as organic, reportedly yielding €6 million in profit. USDA reported fraudulent organic certificates for products including winter squash, leafy greens, collagen peptides powder, blackberries, and avocados. Counterfeit wines with fraudulent DOG, PGI, and organic labels were discovered in Italy.
  • Herbs and Spices. Quite a few reports came out of India and Pakistan about adulteration and fraud in the local spice market. One of the most egregious involved the use of animal dung along with various other substances in the production of fraudulent chili powder, coriander powder, turmeric powder, and garam masala spice mix. Greece issued a notification for a turmeric recall following the detection of lead, chromium, and mercury in a sample of the product. Belgium recalled chili pepper for containing an “unauthorized coloring agent.” Reports of research conducted at Queen’s University Belfast also indicated that 25% of sage samples purchased from e-commerce or independent channels in the U.K. were adulterated with other leafy material.
  • Dairy Products. India and Pakistan have also reported quite a few incidents of fraud in local markets involving dairy products. These have included reports of counterfeit ghee and fraudulent ghee manufactured with animal fats as well as milk adulterated with a variety of fraudulent substances. The Czech Republic issued a report about Edam cheese that contained vegetable fat instead of milk fat.
  • Honey. Greece issued multiple alerts for honey containing sugar syrups and, in one case, caramel colors. Turkey reported a surveillance test that identified foreign sugars in honeycomb.
  • Meat and Fish. This European report concluded that the vulnerability to fraud in animal production networks was particularly high during to the COVID-19 pandemic due to the “most widely spread effects in terms of production, logistics, and demand.” Thousands of pounds of seafood were destroyed in Cambodia because they contained a gelatin-like substance. Fraudulent USDA marks of inspection were discovered on chicken imported to the United States from China. Soy protein far exceeding levels that could be expected from cross contamination were identified in sausage in the Czech Republic. In Colombia, a supplier of food for school children was accused of selling donkey and horse meat as beef. Decades of fraud involving halal beef was recently reported in in Malaysia.
  • Alcoholic Beverages. To date, our system has captured more than 30 separate incidents of fraud involving wine or other alcoholic beverages in 2020. Many of these involved illegally produced products, some of which contained toxic substances such as methanol. There were also multiple reports of counterfeit wines and whisky. Wines were also adulterated with sugar, flavors, colors and water.

We have currently captured about 70% of the number of incidents for 2020 as compared to 2019, although there are always lags in reporting and data capture, so we expect that number to rise over the coming weeks. These numbers do not appear to bear out predictions about the higher risk of food fraud cited by many groups resulting from the effects of COVID-19. This is likely due in part to reduced surveillance and reporting due to the effects of COVID lockdowns on regulatory and auditing programs. However, as noted in a recent article, we should take seriously food fraud reports that occur against this “backdrop of reduced regulatory oversight during the COVID-19 pandemic.” If public reports are just the tip of the iceburg, 2020 numbers that are close to those reported in 2019 may indeed indicate that the iceburg is actually larger.

Unfortunately, tracking food fraud reports and inferring trends is a difficult task. There is currently no globally standardized system for collection and reporting information on food fraud occurrences, or even standardized definitions for food fraud and the ways in which it happens. Media reports of fraud are challenging to verify and there can be many media reports related to one individual incident, which complicates tracking (especially by automated systems). Reports from official sources are not without their own challenges. Government agencies have varying priorities for their surveillance and testing programs, and these priorities have a direct effect on the data that is reported. Therefore, increases in reports for a particular commodity do not necessarily indicate a trend, they may just reflect an ongoing regulatory priority a particular country. Official sources are also not standardized with respect to how they report food safety or fraud incidents. Two RASFF notifications in 2008 following the discovery of melamine adulteration in milk illustrate this point (see Figure 1). In the first notification for a “milk drink” product, the hazard category was listed as “adulteration/fraud.” However, in the second notification for “chocolate and strawberry flavor body pen sets,” the hazard category was listed as “industrial contaminants,” even though the analytical result was higher.1

What does all of this mean for ensuring food authenticity into 2021? We need to continue efforts to align terminology, track food fraud risk data, and ensure transparency and evaluation of the data that is reported. Alignment and standardization of food fraud reporting would go a long way to improving our understanding of how much food fraud occurs and where. Renewed efforts by global authorities to strengthen food authenticity protections are important. Finally, consumers and industry must continue to demand and ensure authenticity in our food supply. While most food fraud may not have immediate health consequences for consumers, reduced controls can lead to systemic problems and have devastating effects.

Herbs remain a target for fraudsters. The latest investigation of sage samples by the Institute of Global Food Security (IGFS) at Queen’s University Belfast used a combination of spectroscopic and chemometric methods to check whether sage contained 100% of the actual herb. One quarter of samples from the UK included unapproved (fortunately, no hazardous) bulk material, such as tree leaves, some in significant concentrations of more than half of the product.

The European Commission’s Rapid Alert System for Food and Feed (RASFF) Portal shows a notification about the use of olive leaves in oregano in Turkey. Addition of cheaper bulking agents to herbs and spices is a common way of achieving a higher profit margin for pricier herbs. The olive leaves were classified as an unauthorized novel ingredient; however, they are known to be used for the adulteration of oregano. An investigation of commercial oregano samples showed that one quarter of samples were adulterated with other plant leaves, and two of the samples didn’t even contain any oregano.
