Enviro News Asia, Rome — A new publication by the Food and Agriculture Organization of the United Nations reveals that fish fraud is widespread across global markets and poses risks to biodiversity, human health, and economic systems, while also identifying a growing range of scientific tools to combat the practice.
The report, Food fraud in the fisheries and aquaculture sector, was developed through cooperation between FAO’s Fisheries and Aquaculture Division and the Joint FAO/IAEA Centre of Nuclear Techniques in Food and Agriculture. It provides a comprehensive overview of the scale, drivers, and forms of fraud affecting the global fisheries and aquaculture sector, valued at an estimated US$195 billion annually.
According to the publication, empirical studies suggest that up to 20 percent of global fish trade may be affected by some form of fraud, a proportion higher than in meat or produce sectors. The report defines fish fraud as a deliberate practice intended to deceive, with consequences ranging from economic loss and consumer deception to threats to food safety and the sustainability of fish stocks.
The most common forms of fish fraud include species substitution, mislabeling of origin or sustainability claims, adulteration, counterfeiting, and product tampering. Practices such as selling lower-value fish as premium species, disguising farmed fish as wild-caught, or altering products to appear fresher generate strong economic incentives throughout supply chains.
The report highlights that the lack of standardized definitions, limited inspection capacity, and the sheer diversity of more than 12,000 seafood species consumed globally make it difficult to establish accurate baseline estimates of fraud prevalence. Studies cited indicate that seafood mislabeling can reach up to 30 percent in restaurant settings in some regions, while less than one percent of imports are tested in certain major markets.
To address these challenges, FAO advocates harmonized labeling requirements, mandatory use of scientific species names where feasible, and strengthened traceability systems. The report also reviews advanced analytical techniques such as DNA barcoding, stable isotope analysis, nuclear magnetic resonance, and enzyme-linked immunosorbent assays, alongside emerging innovations including portable X-ray fluorescence devices and machine-learning models.
The publication documents successful initiatives in countries such as Italy, Argentina, and the United States, where coordinated efforts involving government agencies, academia, and the private sector have significantly reduced seafood mislabeling over time.
FAO emphasizes that prevention, enforcement, and private-sector engagement are essential to combating fish fraud. The organization, together with the Codex Alimentarius Commission, is developing international standards to address food fraud, while the Joint FAO/IAEA Centre continues to provide technical assistance to member states seeking to strengthen testing and regulatory capacity.
