Tunisian company CHO, which is one of the largest olive oil producers in the southern Mediterranean has introduced blockchain technology to assure the integrity of its brand Terra Delyssa extra virgin olive oil. CHO is the latest major food company to join IBM’S Food Trust Network. The blockchain will track Terra Delyssa across eight quality assurance checkpoints, including the orchard where the olives were grown, the mill where olives were crushed, and the production facilities where the oil was filtered, bottled and distributed.

This review provides general information about olive oil and the possible causes of adul­teration, mislabelling, counterfeiting, and fraud of the product. It reviews the possible adulterants in olive oil, the underly­ing causes of adulteration, and how to test for the pres­ence of these adulterants. Data on trade and market dynamics are included. Also, the review focuses primarily on current deceptive practices in the global olive oil trade rather than historical adul­terations.

Indian researchers have developed a PCR method based using 3 different primers on the mitochondrial gene 12S rRNA. The method produces a cow specific amplicon (346bp) and a buffalo specific amplicon (220bp). The method can detect 0.5% addition of buffalo milk to cow milk. Although this test has been used in India to determine buffalo milk adulteration of cow milk, it could be adapted to determine cow milk adulteration of buffalo milk e.g. in the case of mozzarella cheese.

The FDA has launched its Food Defense Plan Builder (FDPB) Version 2.0 software programme, which is a user-friendly tool, designed to help owners and operators of food facilities create a detailed food defence plan specific to their facility and products. It is designed to assist food operators with meeting the requirements of the Mitigation Strategies to Prevent Food Against Intentional Adulteration regulation (21 CFR Part 121) (IA rule). The software provides a simple-to-use, fill-in-the-blanks system that—when finished—can generate a complete report that is consistent with FDA’s existing regulations and guidance on food defence. While the finished report that the software generates does not constitute FDA approval of a food defence plan, the tool certainly goes a long way in helping a processor organise, create and document a detailed food defence program and strategy.

Although infrared (IR) spectroscopy is often used as a simple and rapid method to screen for economically motivated adulteration in spices, conventional microscopy remains the reference method. In this research, micro-FTIR imaging, along with PCA (Principle Component Analysis) were used in combination with microscopy to develop a non-targeted method for detecting a broad range of organic and mineral bulking agents that could potentially be used to adulterate black pepper. The method has been validated, and the results are classed as typical or atypical, where the latter indicates a high probablity of adulteration, and is followed up with a multitool investigational approach for the detection and identification of the potential adulterant.

ASK restaurant chain was fined £40,000 in Swansea Magistrate Court  on 14 January for misleadingly describing one of their dishes - "Aragosta e Gamberoni" (lobster and king prawns). The lobster component of the dish was a reformed product containing only 35% lobster with white fish protein and white fish. Sales of the dish amounted to £3m across the UK since it was launched in 2014, though the charge spanned the period between 1 December 2016 and 20 March 2019 - when Swansea Trading Standards alerted ASK and removed the dish from its menu.

In order to verify labelling compliance and evaluate the existence of fraudulent practices, 250 sausage samples were purchased from local markets in Sichuan Province and analysed for the presence of DNA from chicken, pork, beef, duck and genetically modified soybean using real-time and end-point PCR methods. In total, 74.4% (186) of the samples were properly labelled, while the other 25.6% (64) were mislabelled and potentially adulterated samples.The most common mislabelling was the undeclared addition of, or contamination with, duck meat, which is cheaper than pork or chicken.

Smoked salmon is a high value product, and it is misleading to consumers if it is sold chilled but has been previously frozen/thawed. Italian researchers prepared three groups of products each with 36 samples - Group A stored chilled, Group B frozen at −18°C for 30 days, and Group C stored at −3°C for 30 days. Histological slides of all the samples were prepared, and given to two experienced microscopists as blind samples, who were able to accurately distinguish between chilled and previously frozen/thawed smoked salmon.

A USDA National Bioengineered Food Disclosure Standard, which requires US food manufacturers and importers to label food for retail sale disclosing information about its GMO content, becomes mandatory on 1 January 2022. Although the US food industry has two years to implement the new rule, a deadline of 1 January 2020 is when food manufacturers have to decide whether and how they will need to make GM ingredient disclosures, and what records they will be required to keep. The new rule does not cover foods, which are highly refined e.g. vegetable oils, where the GM DNA is not detectable, and small companies with less than US$ 2.5 million sales are exempt from disclosure.

However, many larger US companies are awaiting the US Agricultural Marketing Service (AMS) to issue guidelines on how the new rule will be enforced, and what will be required. AMS is committed to provide two different sets of instructions for use by food manufacturers, importers and certain retailers. The first set of instructions, released on 17 December 2019, covers how companies can validate or verify the accuracy of a refining process to render bioengineered material undetectable. AMS is taking comments on the draft instructions until 16 January 2020. AMS will publish a second set of instructions to provide guidance for companies on how to select testing methods to determine whether a food product or ingredient contains detectable levels of GM genetic material. 

There is flexibility as to how GM foods are disclosed.Companies with annual sales of more than US $2.5 million can use digital codes, list BE ingredients in text on their label, put one of two BE symbols on their packaging, or supply consumers with a number they can text to receive information via their cellphone. In addition to these, companies with $2.5 million to $10 million in annual revenues can also disclose via a website or a phone number that consumers can call to hear the disclosure. Industry sources say they expect most companies to disclose GM ingredients via digital codes, such as the SmartLabel system.

Authorities in Spain and Portugal, coordinated by Europol, have uncovered what they are calling a criminal network involving contaminated clams that were responsible for the food poisoning of at least 27 individuals in Spain. The investigation into the trafficking of contaminated clams resulted in dismantling this criminal network involving poachers, intermediaries and distribution companies, and the location of hideouts where harvested clams were stored in Portugal. The criminal network was active for at least a year earning up to €9 million with more than 1 000 tonnes of illegally caught clams. The illegal clams were harvested in Portugal, and then moved to Spain for the most lucrative seasons – the summer and the end-of-the-year holidays. After a brief clean up, the contaminated clams were sold in markets and restaurants. Washing the clams eleminated the bacteria (E. coli), but did not eliminate the viruses (Norovirus genogroup I and II and Hepatitis A).

Romanian researchers have applied FT-Raman spectroscopy and metabolomics to classify a sample set of 126 wines, originating from Romania and France, with respect to cultivar, geographical origin and vintage. Cultivar recognition was successfully achieved for four grape varieties (Sauvignon, Riesling, Chardonnay, Pinot Gris), and the subtle particularities existing between the Chardonnay wines, coming from the two countries, because of terroir influences were observed. In addition, a 100% separation in both initial and cross-validation procedures for geographical differentiation between the two origin countries, as well as, among the three Romanian areas (Transylvania, Muntenia and Moldova) were obtained. The limitations of this approach, and the importance of choosing meaningful data sets, in terms of representativity for each classification criterion, are addressed in this paper.

Pork made from plants launched by Impossible Foods

A plant-based pork substitute has been launched in Las Vegas by one of the leading "alternative meat" producers.

Impossible Foods, the firm behind the Impossible Burger, says it hopes to appeal to a global audience with its latest vegetarian-friendly meal, which it unveiled at the CES tech show.

Pork is currently the most widely consumed meat in the world.

The company hopes the product will help it break into China. But one expert said it might find that a challenge.

The first product to feature the foodstuff - the Impossible Sausage - will be available next week at 67 Burger King restaurants in the US, in a sandwich-based dish called the Croissan'wich.

Two Long Island, New York, companies and their owners have pleaded guilty to mislabelling giant squid from Peru as octopus, which commands a higher retail price than squid. From 2011 to 2014, the defendants imported, processed, marketed, sold, and distributed over 51,000 kg of squid worth US $1.1 million that they had falsely labelled as octopus. The defendants admitted to defrauding over ten grocery stores that in turn sold the seafood product to consumers. The defendants await their sentencing.

Looking to 2020, among the challenges faced by the food sector, which can affect their reputation and market, are food allergies, food fraud and climate change. Food allergies amongst the population especially in children are on the increase, and allergy related recalls have increased by 20% in 2019, along with some tragic high profile allergic reaction deaths. Hence industry, especially the food service sector, will need to take more precautions in future. Climate change will also potentially impact on industry affecting its raw materials and ingredients supplies and production in particular. Food fraud continues to remain a high profile and challenging issue for industry, especially where there is reliance on imported raw materials and ingredients.

Implementation of the new Official Controls Regulation EU 2017/625 on 14 December 2019 is part of a larger initiative - the Smarter Rules for Safer Food (SRSF) package, which covers animal and plant health regulations as well, and is designed  to modernise, simplify and improve existing health and safety standards for the agri-food chain. In particular, an IT system TRACES New Technology will become the new system for notifying imports from outside the EU. This will be one part of a larger new computerised system for official controls (Integrated Management System for Official Controls, IMSOC), which will integrate TRACES with RASFF, the  EU Food Fraud Network and other IT systems.

CBD - cannabidiol - isn't marketed as medicinal cannabis. It doesn't have a psychoactive element that makes the user high. Some studies indicate it can help with childhood epilepsy seizures, and other people think it helps them too.

There has been a spike in demand within the last twelve months, according to manufacturers. Non-medicinal CBD is now on sale in High Street shops across the country, including chemists. But the National Pharmacy Association says the products need clearer information and better checks on content.

 Cannabidiol oil is being added to a range of products - from water, to chocolate, to make-up, tea and coffee. Manufacturers claim sales in the UK are as much as £300m at the moment.

It's illegal to print any health claims on the products, but it's a grey area as to who checks the ingredients, or the amount of CBD oil actually contained in each product, many of which can be very expensive. CBD is classed as a food supplement, so it's governed by the Food Standards Agency. FSA said it expects "companies to comply with the novel foods process, which includes submitting safety information about their products"."The FSA is considering the best way to ensure CBD food-related products currently on the market move towards compliance," it added.

In the meantime, customers buying any CBD product have no guarantees if the product is safe, or indeed if it contains any CBD oil at all.

Michele Suman, Head of Food Safety and Authenticity Research at Barilla Spa, in Parma discusses the latest challenges and innovations effecting the industry in an interview with New Food's editor. He will be elaborating the use and validation of non-targeted methods at next year's Food Integrity Conference in March in Twickenham, London, much of which was developed in his work in the EU Project FoodIntegrity.

Chinese researchers have developed a rapid, specific and sensitive method in a single duplex polymerase chain reaction (duplex PCR), using  specific primers of based on 16S-RNA genes from camel and bovine mitochondria and D-LOOP genes from horse and goat mitochondria. The duplex PCR was applied to the binary mixtures of raw milk in fixed percentages, as well as processed dairy products (freeze-dried, pasteurised, and ultra-high temperature (UHT) sterilised with the same mixtures and commercial samples). The limit of detection (LOD) of special milk adulterated with bovine milk was 0.1% in raw milk mixture. Pasteurised and UHT sterilised milk raised the LOD to 0.2% and 0.5%, but freeze-dried milk did not raise the LOD.

Species substitution of seafood is a major global problem. German scientists have developed a rapid, easy to use, DNA microarray for fish species identification based on cytochrome b and 16S rDNA probes. The microarray test takes only 4-5 hours to complete, and identifies ten important commercial fish species. The microarray was validated using 67 authentic fish species, and was able to clearly identify the 10 species even from closely related species of fish.
