How to design a food fraud testing plan

Authenticity testing of ingredients and foods is an important tool in the fight against food fraud, but it’s not easy to get it right.  Here are our recommendations to help you design a food authenticity testing plan.

  1. First define the goals of the testing plan.  Because different materials have different food fraud risk profiles, you will need a different testing protocol for each material that you want to test.  For each material to be tested, choose a test type and laboratory and set accept-reject criteria for test results.  Use our testing checklist to help.
  2. Decide how samples will be collected, and define the sample size with the help of your chosen laboratory. For each lot or batch of material that needs to be tested, figure out how to obtain a sample that is properly representative of that batch. Sampling protocols will depend on the size of the lot, the form of the food (solid, liquid, bulk, etc.) and the practicalities of accessing materials within the batch.  Learn more about sampling protocols from the US FDA’s laboratory manual.
  3. Choose a frequency of testing for each material and document it in the plan.
  4. Write down your goals, test methods, accept/reject criteria, sampling procedures and approved laboratories.  This written information will be the foundation for your testing plan document. Add a description of what action you will take if you get results that confirm or imply authenticity problems with the sample. Who will you report the results to? Who is responsible for making decisions about actions to be taken?  Add document control features and file the plan within the food fraud section of your food safety management system.
  5. Implement your plan.  Be prepared to change your test frequencies or test methods as new information becomes available.  Review your test plan at least annually to make sure it aligns with your food fraud vulnerability assessment results.

Fraudulent practices cost chicken processor £37m

A large chicken processing business, 2 Sisters was the biggest supplier of supermarket chicken in the United Kingdom with a turnover of £1.1 billion in 2017.  During that year, an undercover investigation revealed poor hygiene practices and tampering with date codes was taking place at one of the firm’s processing plants in West Bromwich.  Investigators also alleged that products returned from distribution centres that should have been destroyed were repackaged as if they were fresh, and that the ‘kill dates’ for chickens were deliberately misrepresented so as to extend the expiry date of the finished products.

The Food Standards Agency investigated and in addition found fraudulent practices within the Salmonella testing of the carcasses.  Salmonella testing is a regulatory requirement in the United Kingdom.  In the wake of the investigations, operations at one plant were suspended for 2 weeks, while another was closed permanently.  In April, it was announced that another plant, in Scotland will be closed later this year.

This week, 2 Sisters reported losses of £38 million for the year, a figure that was reported to have ‘ballooned’ by 80% after the fraudulent practices were uncovered.

Food Fraud Risk Database

It’s huge, it’s completely free and open-access; no log-in required.  It’s our

Food Fraud Risk Information Database

Compiled by food fraud experts and containing information about hundreds of different food types, including past incidences of food fraud and emerging threats, you can use it to meet the requirements of your food safety management system, for

  • food fraud vulnerability assessments,
  • food safety risk assessments
  • hazards from intentional adulteration requiring preventive controls (FSMA)
  • pre-filtering and
  • horizon scanning for emerging threats

You can choose to ‘watch’ the database to receive notifications every time new information is added.  You can also watch individual food types (say “Beef”) to receive updates for just that food type.

Access is free, although if you want to receive notifications you will need to create a (free) Trello account.  We do not receive income from Trello for new sign-ups.

Cinnamon fraud warning

Cassia bark, which resembles cinnamon bark has been imported to India from China in large quantities in recent months.  Cassia is a common diluent and substitute for cinnamon.  Cassia bark is toxic.  Just last year researchers found seven of ten samples of cinnamon bark in India to have been adulterated with cassia.  India is the world’s largest exporter of spices.

Cinnamon is at very high risk of fraudulent adulteration, substitution and dilution and the increase in cassia trading has increased that risk.  Purchasers of cinnamon should remain vigilant, and those purchasing in large volumes should implement authenticity testing regimes.

Industrial dye adulterants in wealthy countries

There have been reports of illegal dyes found in jars of beetroot in Germany.  The preserved beetroot contained Rhodamine B.  This follows previous reports of adulteration of ‘natural plant extract’ colourants in Europe.  The ‘natural’ extracts were supposedly made from hibiscus and beetroot but contained Reactive Red 195.  Illegal dyes, including those designed for textile manufacturing are common food adulterants in developing countries, where they have been used by unscrupulous merchants in large-scale manufacturing, artisan food businesses and at the retail level.  Developed countries are not immune.  Purchasers of very brightly coloured food should remain vigilant to this risk.

Food packaging fraud uncovered in USA

A study in North America found toxic chemicals in one third of food packaging materials that are supposed to be safe for food contact.  It is unusual for packaging to be tested for the purposes of fraud detection.  The substitution of cheaper low grade packaging materials for food-grade materials would be very profitable.  The cost of raw materials for plastic packaging is rising which increases the likelihood of food fraud.  There is likely to be significant fraud occurring in the ‘food-grade’ plastics sector and this fraud can be expected to continue.

Free-range milk hits the shelves

Free-range milk has been introduced to the United Kingdom by a large supermarket chain.  There are no laws that define free-range milk in the United Kingdom.  Premium priced ‘free-range’ milk is likely to be indistinguishable from other milks to the average consumer.  There is a risk that unscrupulous operators will mis-declare milk as ‘free range’ or take advantage of the lack of legal definition of such.  There is also a risk that some dairy brands may inadvertently breach their own claims about the number of days a herd has been outdoors.  Milk from less well-known brands and small traders is most at risk of inaccurate claims around ‘free-range’.

Trouble is brewing in craft beer

Walmart in the USA has been accused of misleading consumers by marketing a mass-produced beer as a ‘craft-brew’.  Ironically the beer is sold under the brand name ‘Trouble Brewing’.  Craft beer attract significantly higher prices than mass-produced beer and is at high risk of being fraudulently marketed.

Coming to a store near you….

Keeping abreast of food fraud and food safety news is a daily activity and one of my favourite work tasks.  This week, as I skimmed through food industry trivia and pondered the launch of chocolate cheese (seriously), the two most alarming and unusual food fraud incidents I came across were news of thirty five businesses who were caught by Chinese authorities adding opium to food and a British business that was prosecuted for selling ‘almond’ powder that contained peanut.  By the way,  you did see that correctly: opium.  And just for the record, opium is not a permitted food additive.  Peanut-contamination of anything is, of course, a very serious risk to the safety of allergic consumers and has resulted in deaths in recent years.  It’s tragic to see that this type of adulteration continues to occur.

Having digested thousands of words of information about prosecutions, investigations, trends in food fashions and the changing regulatory landscape, I began to notice some patterns and found a couple of big red flags for future risks of food fraud.

Halal

Halal certifications are increasingly needed for market access for almost every food type at both the retail and wholesale level.  A halal product is often indistinguishable from its non-halal counterpart which means that everyday consumers are not able to verify food sellers’ claims about halal status.  Falsely claiming halal for a food item is an easy fraud to perpetrate, especially during the retail sale of un-packaged food in restaurants and takeaway stores.  Halal fraud can be as sophisticated as forgery of certification documents accompanying bulk shipments of food or as simple as dishonest signage in a takeaway store.  There have been a number of incidences of halal fraud in the news lately and these are almost certainly the tip of the iceberg.  I see very high risks in the South East Asian countries of Indonesia and Malaysia; these being some of the world’s biggest markets for halal food and having variable and sometimes chaotic food supply chains accompanied by uneven regulatory enforcement.  However, halal forgery can happen even in the most sophisticated markets with a recent prosecution in the United Kingdom in which the fraudster is alleged to have netted a quarter of a million pounds.  With this kind of money up for grabs, you can expect halal fraud to continue.

Is this meat halal?

Probiotics

Probiotics are among the hottest food ingredients for the healthy eating market right now.  New technology is claimed to enable probiotic bacteria – good bacteria – to survive in an ever-increasing range of food types, taking them beyond traditional yoghurts and ‘Yukult’ style dairy drinks.  Probiotic foods command a premium price and, as with many of the most vulnerable food fraud targets, the probiotic components are indiscernible to consumers.  There is a real and growing risk that fraudulent claims will be made about the quantity and types of live bacteria in food products, with the possibility of both accidental and deliberate frauds.  Any food business can make a mistake with formulations and shelf life, leading to discrepancies between the quantity of live bacteria in the food and what is claimed on the pack.  Premium brand owners are less likely to risk their reputation with unsubstantiated claims and these businesses are more likely to have the in-house expertise and resources to properly verify their on-pack claims.  It’s the smaller food companies and newer brands that I worry about:  they are much more likely to find themselves inadvertently or knowingly selling ‘probiotic’ products that don’t live up to the marketing hype.

Cold Brew Coffee

Can you fake cold brew coffee?  Cold brewed coffee appears to be here to stay but it has a high price tag and would be easy to fake.  Could the average consumer taste the difference between conventional and cold-brew coffee?  I’m pretty sure that I couldn’t, especially when served icy cold or with lots of milk.  The production method for cold brewed coffee is slower than conventional brewing, which usually means more costly.  And that means food businesses could be tempted to cut a few corners.  Even hipster brands that build their messages around product authenticity can find themselves in a scandal when financial pressures increase, as was the case with an ultra-premium bean-to-bar chocolate brand recently.  I wouldn’t be surprised to see a few incidences of fraudulent claims about cold-brewed coffee hitting the headlines this year.
