Complement this article with what food safety is, a related but distinct concept.
What is food fraud?
Food fraud occurs when a food is sold, described or labeled in a deceptive way for economic gain: diluting an expensive ingredient with a cheaper one, substituting one species for another, falsifying geographic origin or overstating quality attributes (for example, "extra virgin" or "organic" without meeting the standard). Unlike food safety, which focuses on health risk, food fraud is above all economic deception of the consumer, although in some cases it can also involve a real health risk.
Most common types of food fraud
Economic adulteration
Diluting or blending a higher-value product with a cheaper one without declaring it: for example, olive oil mixed with cheaper vegetable oils, or honey diluted with sugar syrups.
Species substitution
Selling a fish or seafood species different from the one declared on the label, usually a cheaper or less desirable one presented as premium.
False origin or misleading labeling
Declaring a geographic origin, a production method ("cold-pressed," "artisanal") or a certification that the product does not actually meet.
Why is it a risk, even when it doesn't always cause direct harm?
Food fraud harms the consumer economically as well as legitimate producers who do meet the declared standard, distorting competition. In addition, in certain cases the risk goes beyond the economic: a species substitution can introduce an undeclared allergen, and adulteration with an unauthorized additive can represent a real health risk, not just a reputational one.
How is food fraud detected in the laboratory?
Unlike microbiological analysis, which looks for microorganisms, fraud detection requires authenticity testing: chromatography and mass spectrometry to identify chemical composition and detect undeclared blends, isotopic analysis to verify geographic origin, and genetic markers (DNA barcoding) to confirm the declared species in fish, seafood and meat.
Who regulates food fraud?
Agencies such as the CFIA in Canada, the FDA and the EU Food Fraud Network maintain specific sampling and authenticity verification programs, in addition to the labeling inspections they already carry out as part of general health surveillance. The highest-risk products tend to recur year after year in these reports: olive oil, honey, spices, fish and wine.
Common mistakes when addressing food fraud
- Assuming a food safety plan (HACCP) already covers fraud risk, when it requires its own supplier verification controls.
- Not auditing suppliers of high fraud-risk ingredients (oils, honey, spices) with periodic authenticity testing.
- Confusing a fraud finding with a safety finding when communicating it internally or publicly.
Conclusion
Food fraud is an economic — and sometimes health-related — risk distinct from microbiological contamination, but just as real. Verifying the authenticity of the highest-risk ingredients with the same analytical rigor applied to safety is what allows a company to protect both the consumer and its own reputation.

Frequently asked questions
Is food fraud the same as a food safety alert?
No. Food fraud is economic deception (false composition, origin or labeling); food safety refers to the risk of harm to health. They can overlap, but they are different concepts.
Which products are most vulnerable to food fraud?
According to reports from agencies such as the CFIA, olive oil, honey, spices, fish and wine consistently rank among the products with the highest rate of authenticity non-compliance.
How does a company protect itself from fraud by its suppliers?
By verifying the authenticity of high-risk raw materials with periodic laboratory testing and requiring traceable origin documentation from suppliers.
