Sushi, a popular culinary choice, unfortunately often becomes subject to mislabeling. Studies show that about 20% of tested fish aren't labeled correctly. his deception not only raises concerns for individuals with dietary restrictions or food allergies but also poses threats to wildlife if protected or endangered species are involved. Such fraudulent practices commonly involve substituting a cheaper fish for a more expensive one, leading to financial gain at the expense of unsuspecting consumers. It's important to note that these actions violate FDA regulations in the United States and can result in severe legal consequences. To determine how true this is, we used a method called DNA barcoding in our study. This method identifies species by comparing their DNA to a large database of known DNA sequences. 25 different sushi products were purchased throughout Maryland with the aim of determining the true identity of the fish used in these products. Our investigation revealed instances of mislabeling, with two samples purchased from local stores being inaccurately labeled. Specifically, Samples 2 and 10, initially identified as whitetail, were determined through DNA barcoding to be yellowtail.
