The Association of Food and Drug Officials (AFDO) is calling for the urgent modernizing of US food recall processes and the need to enhance data-sharing among federal, state, and local food safety and public health agencies to better protect consumers and ensure swift, effective responses to contamination events.

The recent lead chromate contamination incident in cinnamon applesauce pouches, in which it has been determined that toxic lead chromate was added to cinnamon for economic gain and sickened over 500 children in the US, AFDO say illustrates continued critical gaps in the US national food recall system.

This incident is a good example of where food fraud is also a food safety issue.

Today, the European Commission has published the results of the EU-wide coordinated action “From the Hives” on honey contaminated with sugars.

These investigations aimed to put a stop to operators voluntarily placing contaminated honey onto the EU market and sanction them accordingly if needed. Of the 320 samples taken at EU borders and analysed by the Joint Research Centre (JRC), 147 (46%) were suspected of being non-compliant.

This suspicion rate was considerably higher in comparison to an earlier EU-wide coordinated control plan conducted in 2015-17, where 14% of the analysed samples did not comply with established benchmark criteria to assess honey authenticity.

However, the JRC applied a different set of methods, with improved detection capability, throughout the current exercise, which may explain this contrast.

An article published in the I online newspaper reports on the ongoing risk of herbs and spices adulteration.  

Investigators and analysts have told i that the $20bn (£17bn) global herbs and spices industry is being increasingly targeted by organised crime gangs and fraudsters determined to use disruptions to global supply chains, caused by factors from Brexit to Covid-19 to the war in Ukraine, to cash in with fake, adulterated or contaminated products.

This article reviews recent surveillance findings, common adulterants, detection methods and includes comments from the National Food Crime Unit and the Scottish Food Crime and Incidents Unit.

The European Commission published today the results of the first coordinated control plan on the authenticity of herbs and spices launched by the Directorate-General for Health and Food Safety.

It has been carried out by 21 EU Member States, Switzerland and Norway, with the technical support of the Joint Research Centre, which performed nearly 10,000 analyses. The plan is the largest investigation so far into the authenticity of culinary herbs and spices in terms of participating countries and samples analysed (1885).

The main conclusions were as follows: 

• The overall rate of suspicious samples was 17% (323 of a total of 1885 analysed samples), which is less than what was previously reported in the scientific literature or by national food control institutions.
• The oregano supply chain was most vulnerable as 48% of samples were suspicious of being adulterated, in most cases with olive leaves.
• The percentage of samples which were suspicious of adulteration were 17% for pepper, 14% for cumin, 11% for curcuma, and 11% for saffron.
• The lowest suspicion rate (6%) was found for paprika/chilli.
• The majority of suspicious samples contained non-declared plant material; in 2% of the analysed spice samples non-authorised dyes were detected. One sample contained a high level of lead chromate.
• In two cumin, 45 oregano, and four pepper samples copper compounds above the relevant maximum residue limit set by Regulation (EC) No 396/2005 were found.
• No specific trend regarding the rate of potential fraudulent manipulations along the supply chain (countries of origin/importers/wholesalers/processors/packagers) could be observed. However, for certain stages (domestic production, local markets, border control, and internet) the number of samples tested was too low to enable statistically meaningful comparisons.

Foreword by the Government Chemist

Next Generation Sequencing (NGS) is a powerful tool for rapidly and cost-effectively identifying and characterising plant, animal and microbial species present in mixed food samples.

The application of NGS to food authenticity, adulteration and safety testing is a constantly evolving field with its own unique set of challenges that need to be explored. Further work needs to be conducted to better understand the performance characteristics and establish relevant performance criteria and metrics, to enable results generated in different laboratories to be compared and interpreted with equal confidence.

Following concerns raised from food industry members on the use of NGS for the quantitative determination of food ingredients, the Government Chemist engaged with Defra’s Authenticity Methodology Working Group (AMWG) [1] and its Technical Sub-Group (AMWG-TSG), resulting in the AMWG producing a view [2] on the use of NGS for food authenticity testing [3].

One of the frequently encountered types of adulteration is the adulteration of meat and animal products. In its most recent annual report [1] , the Food Fraud Network showed data that in the top ten product categories, fish and fish products take the second place, meat and meat products the third and poultry the fifth. Jointly, these three animal product categories eclipse any other product category.

There are different types of fraud that can be found in animal products. These include addition of illegal substances like melamine to milk, the treatment of tuna with carbon monoxide, and the replacement of high-quality species with lower quality ones, or even illegal ones. An example for this can be found in the publication by Fang and Zhang [2], where the addition of murine meat to substitute mutton has been reported.

Since there are many animal species that can be used for adulteration, using a species-specific PCR is often not economically viable when the adulterant species is not known. Here, the DNA barcoding approach is the better choice to cover a much wider range of species.

In the literature, numerous publications can be found that describe different primer sets to be used for barcoding. Unfortunately, not all methods have been thoroughly validated for the species they can, and, equally important, cannot detect.

The German §64 Food and Feed Law Methods Group for Animal and Plant Speciation has developed a tool that will help scientists to quickly determine which species can be detected and which cannot with a specific set of primers.

The tool, called BaTAnS – short for Barcoding Table for Animal Species – lists relevant publications, identifies the level of validation that has been performed for a specific method (and set of primers).

A study conducted by Universidad Nacional Autonoma de Mexico (UNAM) researchers found traces of dolphin meat in three out of 15 samples of tuna cans on sale in Mexico. 

Lead researcher Karla Vanessa Hernendez Herbert used DNA probes with polymerase chain reaction (PCR) to identify dolphin meat adulteration.

The full report has yet to be published in a journal, but the Herbert and Professor Francisco Montiel Sosa disclosed the results in an interview with Mexican newspaper, Excelsior. The original article can be read here in Spanish., or a summary of the article from SeafoodSource can be found here.

The herbal products, sold worldwide as medicines or foods, are perceived as low risk because they are considered natural and thus safe. The quality of these products is ineffectively regulated and controlled. The growing evidence for their lack of authenticity is causing deep concern, but the scale of this phenomenon at the global, continental or national scale remains unknown.

Reserachers analysed data reporting the authenticity, as detected with DNA-based methods, of 5,957 commercial herbal products sold in 37 countries, distributed in all six inhabited continents. The global survey shows that a substantial proportion (27%) of the herbal products commercialized in the global marketplace is adulterated when their content was tested against their labeled, claimed ingredient species. The adulterated herbal products are distributed across all continents and regions. The proportion of adulterated products varies significantly among continents, being highest in Australia (79%), South America (67%), lower in Europe (47%), North America (33%), Africa (27%) and the lowest in Asia (23%).

In the recent survey, conducted by the Food and Drug Administration Department of India under the milk survey of Food Safety and Standard Authority, the apex regulatory body to ensure food standards and quality in the country, 25 per cent of milk samples failed the quality check.

These samples were not only taken from dairies but also from milk packets.

“Under the survey, conducted by the FSSAI across the nation, we have collected 45 samples from various dairies and packaging units of the city. Over 10 samples have failed to clear the quality test including four contain sodium bicarbonate,” senior food safety officer Manish Swami said.

He said that samples of Mahindra Saboro, the packaged milk launched by Mahindra and Mahindra, were also failed as they contain sodium bicarbonate. “Samples of Saboro were also failed and many of the samples contain more water. Milk samples were also found to contain a neutraliser (sodium bicarbonate or sodium hydroxide) to increase the shelf life of milk. Many samples had fat content lower than what was prescribed by the Prevention of Food Adulteration Act, 1954 (PFA),” he added.

However, samples taken from rural areas were found even better than the set standards in terms of fat content and quality. Swami said that they would serve notices to the adulterators and also send our report to the FSSAI.
