Five men have been arrested in connection with an investigation into how illegal horsemeat, which should have been destroyed, made its way into the food chain. The investigation, which began with raids in June 2019 in 7 locations over Ireland, is being conducted by the Gardaí along with the Department of Agriculture and The Food Safety Authority Ireland.
The season when tea is harvested, as well as the age of the tea can affect its quality, hence authenticating the season/age of high cost teas can be desirable. Chinese researchers have used trace elements and stable isotopes with chemometrics to characterise Pu'er tea according to its production year. Pu'er tea is prepared by drying green Chinese tea, then subjecting it to a microbiological fermentation by naturally occurring moulds, bacteria and yeasts. The tea is then pressed into a variety of shapes.
A total of 86 mineral elements and stable isotope compositions were determined from the Xiangzhujing Pu'er tea in five different production years. Different chemometric techniques were applied to find the best models to predict the production year. Mn,68Zn, and 203Tl were the best authenticity markers for enabling the successful authentication of Pu'er tea with different production years.

The Italian NAS Carabinieri of Florence (Arma dei Carabinieri), supported by Europol, have closed down a network of wine counterfeiters, selling online fake premium Italian wines. Law enforcement officers carried out raids in eight Italian provinces (Avellino, Barletta-Andria-Trani, Brescia, Como, Foggia, Pisa, Prato and Rome). Empty bottles of high quality wines were gathered from restaurants, and refilled with fake wine, then marketed on a big online auction platform. The wines were sold in Belgium, France, Germany, Italy, Spain and the United States, often ending in the glasses of unaware customers of wine bars and catering services. This action is part of operation OPSON IX. Europol’s Intellectual Property Crime Coordinated Coalition (IPC3) coordinated OPSON IX, facilitated the information exchange and provided technical and analytical support to the participating countries. Europol’s IPC3 is co-funded by the EUIPO (European Union Intellectual Property Office) to combat intellectual property crime.
The FSA's Chief Scientific Adviser, Prof Guy Poppy has published on 17 June his review of risk analysis, which began in 2018. Risk analysis is the process of estimating risks to human and/or animal health, identifying and implementing measures to control the risks, and communicating these risks and measures to relevant parties. It has three components: risk assessment, led by science and evidence; risk management, the consideration of management options available by policy officials; and risk communication. When the UK leaves the EU on 1 January 2021, European legislation on food and feed safety will move into UK law to provide continuation of the rules. However, the FSA and FSS will be reponsible for the most of the risk analysis functions that were previously provided by EFSA. The report outlines the FSA's response to this future change:
1. A clearer separation between our risk assessment and risk management to ensure the scientific integrity of risk assessment;
2. An expanded role for our Scientific Advisory Committees (SACs), strengthened by recruiting additional experts and by establishing three new Joint Expert Groups (JEGs);
3. A new UK process for authorising regulated products such as food and feed additives, enzymes, 3 flavourings, novel foods, GM food and feed.
The new approach to risk analysis will also include:
• Developing food and feed safety standards and controls based on scientific evidence e.g. policies, guidance, controls and enforcement;
• Pre-market approvals and post-market reviews of regulated food and feed products;
• Risk-based import controls;
• Handling incidents and food crime.

Lard is a cheaper saturated fat than butter. A rapid method for its detection was developed using a portable Raman spectrometer combined with chemometrics. Samples of butter adulterated with different amounts of lard from 0-100% were prepared and their Raman spectra recorded. Chemometric analysis was applied for the classification and discrimination of butter and lard-adulterated samples, as well as the quantification of lard in butter samples. This method could be applied for in-situ analysis or quality control of butter samples.

The illegal practice of adding sucrose to milk has increased in recent years. Sucrose is used as an adulterant of reconstituted milk to increase the total solids content. This research developed the use of FTIR spectroscopy in combination with multivariate chemometric modelling for the differentiation and quantification of sucrose in cow milk. Trial samples of sucrose adulterated milk from 0.5 - 7.5% were prepared and analysed by FTIR. Chemometric analysis was performed on the spectra, and partial least squares regression (PLS-R) showed the best prediction of adulteration with a detection level of 0.5% w/v sucrose adulteration. The method is simple, non-destructive, quick and needs minimal samples preparation.

In just a few weeks, from April 6 to June 6, U.S. Customs and Border Protection agriculture specialists assigned to the Los Angeles/Long Beach Seaport, intercepted 19,555 pounds of prohibited pork, chicken, beef and duck products arriving from China.
In the first five months of fiscal year 2020, the interception of prohibited meats from China at the LA/Long Beach Seaport has increased 70% compared with the same period the year before.
Most of the unmanifiested animal products were commingled in boxes of headphones, door locks, kitchenware, LCD tablets, trash bags, swim fins, cell phone covers, plastic cases and household goods in a clear attempt to smuggle the prohibited meats.
According to USDA's Animal and Plant Health Inspection Service, China is a country affected by African swine fever, classical swine fever, Newcastle disease, foot-and-mouth disease, highly pathogenic avian influenza and swine vesicular disease.

Demand for avocado oil is increasing in view of its nutritional value and health benefits. Researchers from the University of California have undertaken a study on 22 samples of avocado oil purchased locally or on-line, 5 of which were Californian, the rest were imported mainly from Mexico. The oils were tested for rancidity (peroxide value and free fatty acids), purity and composition (tocopherols and sterols). The results indicated that the majorityof the oils were oxidised before reaching the quality expiry date listed on the bottle. In addition, substitution with soybean oil at levels near 100% was confirmed in two “extra virgin” and one “refined” sample of avocado oil. The authors have called for need to develop standards for avocado oil to ensure consumer protection, and a level playing field in the global trade of avocado oil.
The Food Systems Dashboard is a new tool that aims to describe global, regional and national food systems; to assess the challenges for improving diets, nutrition and health; and to guide its users to set priorities and decide on actions.
The need for this tool was identified by Jess Fanzo at Johns Hopkins University and Lawrence Haddad at The Global Alliance for Improved Nutrition (GAIN) in 2018 when working on the team that wrote the UN High Level Panel of Experts on Food Systems and Nutrition report.
The data are publicly accessible via the online Dashboard, which has a well-designed and easy-to-navigate user interface, as designed by iTech Mission with user testing and feedback from our team and additional pilot testing and modifications planned following the launch. The Figure shows how food systems data are transformed from original data sources to metadata that can be altered through data structural changes and visual mapping resulting in graphical views of data. iTech has visual information design experience across a range of platforms, including the Sustainable Development Goals (SDGs) Dashboard.
The Dashboard is intended as the primary resource for decision makers to find curated, high-quality data and analytics on their country’s food systems. The data gives users insight into the state of their food systems and their effects on nutrition and health. The Dashboard also suggests parts of the food system that may require corrective action through actionable indicators.

The EUIPO Status Report 2020 published this month, brings together its reporting work on intellectual property at EU and at global level. It also contains research on the volume of counterfeit and pirated goods in international trade, and the economic contribution of intellectual property-rights intensive industries to economic growth and jobs. According to a study carried out by EUIPO and the OECD in 2019, estimates of IPR infringement in international trade in 2016 could reach as much as 3.3 % of world trade. Hence, it is estimated that up to 6.8 % of EU imports, or EUR 121 billion per year, are fake goods. In a series of sectorial studies, the EUIPO has estimated lost sales in 11 sectors in the EU (directly in the industries being analysed and across their associated supply chain), as a result of counterfeiting. These losses totalled more than EUR 83 billion per year during the period 2013-2017. In addition, more than 671 000 jobs in legitimate businesses were lost, and the Member States lost EUR 15 billion per year in tax revenue.
A Joint Europol/EUIPO Poly-criminality Report also published in June, suggests that counterfeit goods increasingly being linked to the actions of organised criminal networks and other illegal activities such as drug trafficking, manslaughter, illegal arms possession, forced labour, food fraud, excise duty fraud, VAT fraud, corruption and money laundering.

Squalene is a triterpene, and tyrosol is a simple phenol. Both are found in relatively high amounts compared to other terpenes and phenols respectively in extra virgin olive oil, and are reduced significantly during refining to produce refined olive oil. Both squalene and tyrosol can be determined by hplc (high performance liquid chromatography) after extraction with 2-propanol or liquid-liquid extraction respectively. The feasability of this screening method was first tested on measuring the two markers in 10 commercial samples of EVOO, one commercial sample of virgin olive oil, 2 commercial samples of olive oil (a blend of extra virgin and refined olive oil), and 10 types of vegetable oils. In addition, the method was tested on 6 brands of blended oils (5 of which were 20% EVOO/80% sunflower oil, and one 30% EVOO/70% grapeseed oil). Further samples of olive oil using 50% EVOO, and blended oils with 20% EVOO were prepared. After determining squalene and tyrosol in all of the samples and plotting squaline on the y-axis, and tyrosol on th x-axis, there was discrimination between EVOO and all the other samples, and olive oil samples were differentiated from blended oils. Although this showed feasibility of the screening method, more samples at different concentrations of EVOO, and of virgin olive oil are required to find the sensitivity of the method.

The FDA (US Food and Drug Administration) is allowing temporary flexibility in food labelling requirements for manufacturers experiencing difficulty sourcing some ingredients during the COVID-19 pandemic. It has published temporary guidance to allow for minor formulation changes without updating labels, in order to help minimise the impact of supply chain disruptions associated with the current COVID-19 pandemic on product availability.

The Covid-19 outbreak has caused problems in certain sectors of the food supply chain, for example in meat processing plants, air freight of fresh produce. It means that many food manufacturers are struggling to obtain the all the ingredients in a global food chain for their food products. It also means that the shorter the food chain the less risk there is, and local supply chains are benefitting from this situation.

Not from concentrate (NFC) orange juice sells at a premium compared to orange juice from concentrate. Chinese researchers have used untargeted metabolomics followed by identification of potential markers from standards to distinguish the two types of orange juice. This produced 91 and 42 potential markers present in NFC orange juice using the mass spectrometer injection in positive and negative mode, including 7 tripeptides (reported for the first time in orange juice). A partial least squares discriminant analysis model, based on the potential markers in positive mode was constructed and validated with 97% and 95% accuracy for training and test. The model was successfully applied to commercial samples, and one NFC brand of orange juice was found to be possibly mislabelled.

Blockchain technology is becoming increasingly used in the food supply chain to improve traceability, but the trade-offs between implementation challenges and achievable impact remain unclear. Danish researchers have undertaken a study on six cases of blockchain-based technologies in the food supply chain by applying a technology assessment framework that distinguishes between four different components of a technology: technique, knowledge, organisation, and product. The results highlight how blockchain is not a stand-alone-technology, but rather one element in a system of technologies. While blockchain-based technologies are expected to bring a variety of impacts, only some are directly attributable to the blockchain element such as increased transparency, traceability, and trust. Other impacts such as improved data management are a side-effect of digitising non-digital processes. The long-term impacts of implementing blockchain in the food chain are not yet proven, and require further study.

Polish researchers have used an LC-QTOF-MS/MS (Liquid Chromatography - Quadrupole Time of Flight - Mass Sepctrometer) approach for detecting and identifying rabbit-specific peptide-markers from thermally processed meat products to differentiate rabbit from other commonly-consumed animal species. The instrument identified 49 heat stable peptide markers from rabbit myofibrillar and sarcoplasmic proteins. When 11 heat treated rabbit based pâtés were analysed, 3 of the 49 heat-stable peptides were consistently detected in all the pâté samples and hence considered robust markers for rabbit. Pork, lamb and chicken-specific peptides were also monitored in the pâté samples, and undeclared chicken was found in two of the pâtés.

The FSSAI (Food Safety and Standards Authority of India) analysed 106,459 food samples across India in 2018-19, and found over 15.8% of the food samples were sub-standard, 3.7% unsafe, and 9% mislabelled. The FSSAI have accused 10 Indian states of being unable to ensure food security for consumers as they lack the workforce and adequate food testing laboratory infrastructure. In addition, a research report by Uttra Pradesh based Harcourt Butler Technical University found 70% of adulterated mustard oil in markets in Kanpur, a city known for its important markets for edible oil.
