Students Use DNA Barcodes
to Unmask “Mislabeled” Fish
at Grocery Stores, Restaurants
- High school friends make first student use of DNA barcodes in public marketplaces
- One-quarter of 56 fish samples from 14 stores, restaurants in Upper Manhattan
revealed to be cheaper or endangered fish species.
- Mozambique Tilapia sold as “White Tuna” in sushi
Two New York City high school friends, curious about new DNA barcoding technology, discovered that fish at local stores and restaurants are commonly mislabeled and sold for far more than regular market price.
Worse, in two cases DNA barcode tests revealed that filleted fish sold as the popular Red Snapper (caught mostly off the southeast U.S. and in the Caribbean) was instead the endangered Acadian Redfish (which swims in the North Atlantic).
The students’ report marks the first marketplace application of the four-year-old DNA barcoding technology.
