6 Food Fraud

7 What is Food Fraud? A collective term encompassing the deliberate and intentional substitution, addition, tampering or misrepresentation of food, food ingredients or food packaging, labelling, product information or false or misleading statements made about a product for economic gain that could impact consumer health.

9 Global Issue Food fraud is gaining attention as an emerging international issue. The U.S Grocery Manufacturers Association estimates that fraud may cost the global food industry between $10 and $15 billion per year, affecting about 10% of all commercially-sold food products. 300,000 Children sickened from the 2008 melamine-tainted milk scandal in China 13 countries, 28 companies Affected by beef meat tainted with horse meat in 2014

10 Implication of food fraud Food safety Brand protection Revenue loss Liability

11 Why is Food Fraud Increasing? Food supply is becoming more global and there are complex food supply chain Challenging economic times Increasing pressure for unscrupulous suppliers to commit food fraud Canadian consumers are growing increasingly concerned about food fraud and whether they are eating what they pay for (2017 study, Dalhousie University)

12 Top Fake Foods Olive oil - dilution with less expensive oils like soybean or sunflower or diluting with low quality olive oil Parmesan cheese - wood pulp or potato starch added to prevent clumping Seafood - mislabel species of fish Honey - diluted with high-fructose corn syrup, cane sugar and beet sugar Coffee - adulterated with twigs, stone, barley, and corn husks to increase the apparent weight Saffron - contain marigold flowers, corn silk, chalk, dyed onions and strands of cotton or plastic thread Source: Global News (Feb 18, 2018), Food fraud: 6 of the most commonly faked products and how to avoid them

13 Food Fraud Deterent Risk of detection Evadable testing Ease of implementation Good understanding of supply chain know your suppliers Anti-counterfeiting packaging can deter food fraud

14 Anti-counterfeit Packaging

15 Anti-counterfeit Packaging Anti-Counterfeit Packaging Market by Technology report (MarketandMarket, 2017) estimates global anti-counterfeit packaging market at Billion US in 2016 and is projected to reach Billion US by 2021, at a CAGR of 14.0% Minimize risks by using packaging designed with anti-counterfeiting features Classic solutions use tamper-resistant/evident packaging More sophisticated packaging technologies include track and trace technology and authentication technology with overt and covert features and forensic markers

16 Track and Trace Technology Radio frequency identification (RFID) tags consists of an antenna connected to a microchip which can be applied to the product using a self-adhesive label RFID tags are considered the next generation of bar codes that can track the product throughout the supply chain RFID tags can hold reference information specific to the product, such as names or serial number, but can be made unclonable using a cryptic digital signature A reader is used to verify the authenticity of the product

17 CapTag Technology Patented passive RFID based 'electronic barcode' solution (liquid stops ordinary RFID labels working) Can identify, count & track individual glass or plastic bottles at 10 metres & in bulk, inside sealed cartons & cases or on shelves Labels are small, low cost, paper thin Applied to bottles with all types of metal & plastic caps & closures Fitted overtly on top of, or covertly under, the capsule or closure

18 Authentication Technology Uses holograms, watermarks, specialized ink and dyes, and taggants Three-dimensional holographic labels and watermarks difficult to replicate but end users are able to easily identify and confirm the authenticity of the product Taggant - chemical or physical marker added to materials Physical taggants come in different forms but are microscopic and used at low levels Uniquely encoded, virtually impossible to duplicate and can only be verified with specialized but inexpensive readers Incorporated into the material of the item or into the package or label

19 Authentication Technology Microtrace Uses multi-component chemistry for security ink (Spectral Taggant ) Microtaggant Identification Particles (20 to 1,200 micron) are uniquely encoded numeric sequence that can be incorporated into adhesives, inks, films and paper On-the-spot field testing, provides verification with inexpensive readers and detectors

20 Authentication Technology DNA markers in packaging SigNature DNA markers (Applied DNA Sciences) involves isolation of full, double-stranded plant DNA that is fragmented and rebuilt to form encrypted DNA sequence (DNA chimers) Encapsulated DNA chimer can be incorporate into packaging, inks, varnishes, laminate and metal coatings Technology resistant to extreme environmental conditions such as UV radiation, heat, cold, vibration and abrasion Foods instantly verified as genuine using a special handheld detector to identify the anti-counterfeiting ink

21 Authentication Technology DNA markers in packaging DNA Technologies incorporates DNA taggants into holographic images (DNA Matrix Hologram) Hologram is visually recognized but the security feature relies on spectrum analysis by a specialized reader

22 Anti-counterfeit Packaging Combined use of overt, covert and forensic features can deliver enhanced security and protection Overt technology provides instant visual authentication (e.g. holographic devices) Covert techniques (e.g. RFID, taggant) use microscopic tagging with special readers to confirm authenticity Forensic features include molecular and biological tracers that are difficult to reproduce and to detect (e.g. DNA markers)

23 Anti-counterfeit Packaging Layering of several anti-counterfeiting solutions is the best approach for protection The mix ideally integrates three techniques combined: - Authentication or anti-counterfeiting solution to confirm product is authentic - Track-and-trace solution enables the product to be traced - Enable consumer to access the interactive content by scanning the code on the packaging.

24 Anti-counterfeit Packaging Important that the technology cannot be imitated and not possible to remove it without spoiling the contents of the package Protecting the device is essential Device should be discreet, adapted to the package, provided with innovation technology and seal attached Integration of digital technologies with more physical ones for future applications

25 Future Developments

26 Future Trends Smart Labels New inkjet printing allows thin layers of liquid metal to be deposited into neat, stretchable circuits Development of flexible, printed sensors with integrated sensory can provide real time information Can check temperature to prevent spoilage or validate the freshness of a product or validate product authenticity Source:

27 Closing Remarks Anti-counterfeiting technology development has been driven by brand protection and economic loss Although there is general lack of awareness and affordability of these technologies, recent campaigns by anti-counterfeit trade organizations and interventions from government have increased their use There is potential for widespread use since there is no impact to legibility or durability and the technology is suitable for customer environments
