Fishy Business DNA Testing Has Revealed That Sushi Bar Customers Are Not

Fishy Business
DNA testing has revealed that sushi bar customers are not always getting what they pay for.Scientists at the American Museum of Natural History tested fish from 31 sushi bars and found that the tuna coveted by many diners is often a cheaper substitute,a banned fish,or an endangered species.This could be the result of an honest mistake in the supply chain,or it could be a deliberate attempt to deceive buyers.However,researchers have uncovered a DNA 'barcode' that can accurately identify the type of fish.While still a ways off,the scientist who developed the tuna DNA barcode envisions a small device that can provide instantaneous species identification,which will result in restaurants ultimately providing what their customers are demanding and paying for.
