Food Standards Scotland’s Scottish Food Crime and Incidents Unit (SFCIU) have highlighted four sectors as priorities, which have been targeted and continue to be targeted by criminals committing food fraud:-

- Red meat: fraudulently tagged livestock, stolen livestock, illegal slaughter and substitution of product, false declaration of origin or durability date.

- Fish: substitution by cheaper species or lower quality fish, misdescription of origin especially for salmon, import of illegally treated tuna, fraudulent use of official certification in UK, and impact of Brexit on Scottish supply chain.

- Shellfish: illegally harvested shellfish, misrepresentation of quality and origin of shellfish, falsification of registration and landing documents, and   use of modern slavery and exploitation for harvesting shellfish.

- Alcoholic drinks: counterfeit branded spirits and wine, import or smuggling of fake vodka, production of illicit alcohol, and import and use of material and equipment to produce imitation alcohol products.

Study finds dolphin meat in tuna cans

7857838700?profile=RESIZE_400xA study conducted by Universidad Nacional Autonoma de Mexico (UNAM) researchers found traces of dolphin meat in three out of 15 samples of tuna cans on sale in Mexico. 

Lead researcher Karla Vanessa Hernendez Herbert used DNA probes with polymerase chain reaction (PCR) to identify dolphin meat adulteration.

The full report has yet to be published in a journal, but the Herbert and Professor Francisco Montiel Sosa disclosed the results in an interview with Mexican newspaper, Excelsior. The original article can be read here in Spanish., or a summary of the article from SeafoodSource can be found here.

Animal origin food products, including fish and seafood, meat and poultry, milk and dairy foods, and other related products play significant roles in human nutrition. However, fraud in this food sector frequently occurs, leading to negative economic impacts on consumers and potential risks to public health and the environment. Therefore, the development of analytical techniques that can rapidly detect fraud and verify the authenticity of such products is of paramount importance.


Traditionally, a wide variety of targeted approaches, such as chemical, chromatographic, molecular, and protein-based techniques, among others, have been frequently used to identify animal species, production methods, provenance, and processing of food products. Although these conventional methods are accurate and reliable, they are destructive, time-consuming, and can only be employed at the laboratory scale. On the contrary, alternative methods based mainly on spectroscopy have emerged in recent years as invaluable tools to overcome most of the limitations associated with
traditional measurements. The number of scientific studies reporting on various authenticity issues investigated by vibrational spectroscopy, nuclear magnetic resonance, and fluorescence spectroscopy has increased substantially over the past few years, indicating the tremendous potential of these techniques in the fight against food fraud.

This manuscript reviews the state-of-the-art research advances since 2015 regarding the use of analytical methods applied to detect fraud in food products of animal origin, with particular attention paid to spectroscopic measurements coupled with chemometric analysis. The opportunities and challenges surrounding the use of spectroscopic techniques and possible future directions are also be discussed.

Researchers in Ireland have published a paper which discusses current and evolving techniques to determine geographical origins of meat. The paper explores applications of meat authenticity techniques including spectrscopy, stable isotope ratio analysis, and the measurement of compounds derived from the animals' diets. The authors also discuss challenges in interpretation of the data.
