A recent study by the Complutense University of Madrid (UCM) has found that one in three food products labeled as prawns, shrimps, or crayfish contains a different species. The research highlights concerns about mislabeling, particularly in frozen shrimp products sold at supermarkets.

Frozen Products at the Forefront

The majority of mislabeling occurred in frozen shrimp items, while fresh products were rarely affected. This poses a challenge for consumers seeking authentic seafood, as misrepresented labeling could lead to health risks.

To empower consumers, the study encourages them to buy fresh shrimp from reputable fishmongers. Published in the Journal of the Science of Food and Agriculture, the research calls for more studies on food labeling to promote transparency in the industry.

Methodology and Findings

Researchers analyzed the DNA of 95 shrimp samples from Madrid and Toledo, revealing that 19 products misidentified their actual species. Alarmingly, some products contained multiple species, raising concerns over consumer trust and product authenticity.

The study also found that mislabeling is more common in Pacific and Indian Ocean-sourced products compared to those from the Atlantic. Conversely, aquaculture products showed no mislabeling instances, indicating a potential trend toward greater accuracy.

A Call for Action

With mislabeling posing challenges, the study’s authors advocate for stricter labeling practices to help consumers make informed decisions.
