Restaurants plan DNA-certified premium seafood

Restaurants around the world will soon be DNA technology to new customers who had ordered real caviar fish fillet, rather than replace, a DNA expert to offer, said.
In October, the U. S. Food and Drug Administration formally approved the so-called DNA barcode standards _ a space that identifies a species as a barcode scanner reads a supermarket _ to prevent the mislabeling of two locally produced fruits and imported into the U.S.. Other national regulatory authorities in the world is also considering adopting a barcode DNA as a tool for fast, reliable and cost effective for the identification of organic matter.

David Schindel, a Smithsonian Institution paleontologist and executive secretary of the Consortium, based in Washington for the barcode of life, said he has discussions with the suppliers of seafood restaurants and began to use technology as a means declared the authenticity of the dishes.
"If something really expensive to sell them to consumers to believe that they get what they want to pay" Schindel told the Associated Press.
"We will start with a movement of self-regulation overseen by commercial high-level barcodes kiss as a sign of quality," he said.
Although the DNA test will never be economical all fish, it would be possible to obtain a sample of several ships loaded with fish testing, he said.
Schindel is organizer of the biennial International Barcode of Life Conference will be held Monday in the southern city of Adelaide in Australia. The fourth series of conferences brings 450 experts to discuss new and increasingly diverse applications in science.
The applications range from the discovery of this herd of wild camels Australia Outback to power one million fraud discovered herbal medicines in Malaysia.
Schindel leads a consortium of scientists from some 50 countries control the composition of an extensive reference library of the 1.8 million known species on Earth.
The database of barcodes life so far includes more than 167 000 species.
Mislabeling is common in the area of ​​seafood in general, less expensive types of fish sold, the more expensive varieties. A few students of high school in New York using DNA barcoding of stored food in the kitchen are in a 2009 study that sturgeon caviar was actually labeled as a Mississippi paddle.
In one study, one year earlier, another pair of high school students found that one quarter of the fish samples collected in New York he had been wrongly labeled as the high price of fish.
Mislabeling fish _ which accounts for nearly half of all vertebrate species around the world _ also poses risks to human health and the environment.
In 2007, several people were seriously ill from eating poisonous fish ball illegally imported from China, who are confused angler to circumvent import restrictions in the United States. Endangered species are also sold as the most common species of fish.
