As the novel coronavirus pandemic shuts down businesses globally and sends countries into lockdown, the disruptions are threatening to cut off supply chains and increase food insecurity.

"Supermarket shelves remain stocked for now," the Food and Agriculture Organization of the United Nations (FAO) said in a report released late last month. "But a protracted pandemic crisis could quickly put a strain on the food supply chains, a complex web of interactions involving farmers, agricultural inputs, processing plants, shipping, retailers and more."

The issue, however, is not food scarcity -- at least, not yet. Rather, it's the world's drastic measures in response to the virus.

Border closures, movement restrictions, and disruptions in the shipping and aviation industries have made it harder to continue food production and transport goods internationally -- placing countries with few alternative food sources at high risk.

Airlines have grounded thousands of planes and ports have closed -- stranding containers of food, medicine, and other products on tarmacs and holding areas, said the UN Conference on Trade and Development on March 25.

Heightened instability in global food supply will affect the poorest citizens most, warned the UN's Committee on World Food Security (CFS) in a paper last month.

Even private companies and organizations have called for immediate action to address the looming food catastrophe.

"Governments, businesses, civil society and international agencies need to take urgent, coordinated action to prevent the COVID pandemic turning into a global food and humanitarian crisis," said an open letter to world leaders from scientists, politicians, and companies like Nestle and Unilever.

The FSA has today published guidance to assist food businesses in responding to the coronavirus (COVID-19) outbreak.

The new guidance has been developed with the Department for Environment, Food and Rural Affairs (Defra) and covers a range of areas including good hygiene practice, management of employee sickness, and social distancing for specific food business settings.

It is very unlikely that people can catch COVID-19 from food. COVID-19 is a respiratory illness and not known to be transmitted by exposure to food or food packaging.

The FSA is working with the food industry to ensure that businesses know what their responsibilities are and what actions they need to take to maintain safety standards and protect staff during the outbreak.

The guidance can be found on GOV.UK

Overview

• COVID-19 is caused by a novel coronavirus which is a new strain that has not been previously identified in humans, so there is still a lot of uncertainty
• Food has not been identified as a likely source or route of transmission of the virus
• The global food sector may be impacted both economically and socially, in relation to: human resources, such as changes in key personnel; supply chains of ingredients, packaging, finished products and equipment; sourcing as manufacturers may need to rely on alternative suppliers at short notice; transportation of people, materials and goods.

 Hygiene and Food Safety

• Food handlers are expected to already be well informed and trained about hand hygiene in factory operations (including washrooms and canteens). In the event of lack of access to hand-washing facilities with soap and warm water, sanitisers can be used, but are not as effective if hands are visibly soiled. Please refer to IFST’s Food Science Fact Sheet on ‘Hand Hygiene’ https://www.ifst.org/sites/default/files/Hand_Hygiene.pdf
• Meat products can be safely consumed if cooked thoroughly and handled properly, and WHO guidance mentions that individuals with underlying medical conditions should avoid contact with live animal markets and wild animals
• In line with food safety best practice, good hygiene is important to avoid cross-contamination between raw or undercooked foods and cooked or ready to eat foods, in food preparation areas.

Although the process for application to become a Centre of Expertise is open throughout the year, the UK Government has taken a decision to announce a formal call for new applications once a year.

If you think your laboratory can fulfil the AMWG criteria for a Centre of Expertise then please complete a self-assessment evidence proforma, providing evidence of your capabilities, and return to CoE@foodauthenticity.uk by 31 March 2020.

Your application will be processed and discussed with the Department for Environment, Food and Rural Affairs (Defra), and you will be notified of the outcome by the end of May 2020.

Benefits of being a Food Authenticity Centre of Expertise

• Recognition of your organisation’s food authenticity testing expertise
• Posters of Centres of Expertise are placed on the Food Authenticity Network website
• Centres of Expertise are featured in Food Authenticity Network newsletters
• Centres of Expertise have the opportunity to:
  • Potentially contribute to the resolution of future incidents of national / international importance
  • Support UK food authenticity testing capability by offering analysts advice
  • Work with the Food Authenticity Network & its members (>1,500 members from 67 different countries / territories and in 2019, >12,000 users accessed the website)
  • Work with other Food Authenticity Centres of Expertise.

Background

Following the Elliott review in 2013-14, the UK Government set up the Food Authenticity Network to help bring those involved in food authenticity testing together in a more coordinated way. The Network raises awareness of the range of methods / techniques used to check for mislabelling and food fraud and to ensure that the UK has access to a resilient network of laboratories providing fit for purpose testing to check for food authenticity so that ultimately, consumers can have greater confidence in the food they buy.

Recognising that no one organisation will be equipped with all the necessary expertise in all methods / techniques used in food authenticity testing, and across all of the food commodities, Professor Elliot’s review also proposed the creation of “Centres of Excellence” to cover the different disciplines and techniques involved.

The UK Government’s Authenticity Methods Working Group (AMWG) produced a number of criteria which outlined the type of qualities an organisation offering a particular expertise might be expected to demonstrate to become a ‘Centre of Expertise’. There is an expectation that such organisations should be prepared to engage with and offer support to others in their areas of expertise both within the Network and more widely if required.

In 2015, the UK Government invited organisations working in the food authenticity testing field to consider if they had the expertise, capability and experience expected of a Centre of Expertise and through this process, acknowledged fourteen organisations as Food Authenticity Centres of Expertise.

The European Council has adopted conclusions on further steps to improve ways of tackling and deterring fraudulent practices in the agro-food chain.

In its conclusions the Council recalls that a high level of protection is an overall objective of EU policies concerning health, safety, environmental protection and consumer protection, and recognises that the current EU legal framework on tackling food fraud is adequate.

The Council nonetheless emphasises the need for continuous and improved cross-sectorial cooperation to fight against food fraud. This cooperation should include not only food and feed control authorities, but also authorities involved in the fight against financial crime and tax, customs, police, prosecution and other law enforcement authorities. In relation to this, the Council calls upon the Commission and member states to allocate adequate resources to ensure effective implementation of existing EU legislation by improving the shared understanding of the criteria determining food fraud.

The Council also stresses the need to promote awareness-raising among consumers and to continue to broaden training on countering food-fraud.

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.

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.

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%).

A US federal bill that would require plant-based and cell-cultured meat products to be labelled as ‘imitation’ meat has been welcomed by beef producers and slammed by plant-based meat advocates, as the row over terminology in the burgeoning space heats up. The bill would mean that any imitation meat product would be deemed to be misbranded unless its label bears the word ‘’imitation’’ as well as a statement that clearly indicates that the product is not derived from or does not contain meat. The term beef would exclude both plant-based and cell-cultured meat from using the term. The bill is aimed at transparency of products to consumers. Read full article.

The production of this e-seminar was funded by Defra, FSA, FSS and BEIS under the Joint Knowledge Transfer Framework for Food Standards and Food Safety Analysis.

The Royal Society of Chemistry has published a book on 'DNA Techniques to Verify Food Authenticity'                       (https://doi.org/10.1039/9781788016025), which includes a chapter (number 26) on the Food Authenticity Network.

 About the book:

The food supply chain needs to reassure consumers and businesses about the safety and standards of food. Global estimates of the cost of food fraud to economies run into billions of dollars hence a huge surge in interest in food authenticity and means of detecting and preventing food fraud and food crime. Approaches targeting DNA markers have assumed a pre-eminence.

This book is the most comprehensive and timely collection of material from those working at the forefront of DNA techniques applied to food authenticity. Addressing the new field of analytical molecular biology as it combines the quality assurance rigour of analytical chemistry with DNA techniques, it introduces the science behind DNA as a target analyte, its extraction, amplification, detection and quantitation as applied to the detection of food fraud and food crime. 

Making the link with traditional forensic DNA profiling and describing emerging and cutting-edge techniques such as next generation sequencing, this book presents real-world case studies from a wide perspective including from analytical service providers, industry, enforcement agencies and academics.  It will appeal to food testing laboratories worldwide, who are just starting to use these techniques and students of molecular biology, food science and food integrity. Food policy professionals and regulatory organisations who will be using these techniques to back up legislation and regulation will find the text invaluable. Those in the food industry in regulatory and technical roles will want to have this book on their desks.
