According to a new study using fish DNA suggests, Tuna sushi from your local supermarket might have lower mercury levels and so be safer to eat than sushi from a high end restaurant. It may be noted that the levels on a average , greater than the concentrations considered safe to consume in one day buy the U. S environment Protection Agency and higher than the concentrations allowed In Japan .

A study researcher Jacob Lowenstein, A student afflicted with the American Museum of Natural History in New York, said, "So far, the U. S. does not require restaurants and merchants to clarify what species they are selling or trading, but species names and clearer labeling would allow consumers to exercise greater control over the level of mercury they imbibe”. It may also be noted that with this method, scientists use a specific DNA sequence from an organism called a species “fingerprint” to match a sample of unknown origin with a certain species.

From 54 restaurants and 15 supermarkets in New York, New Jersey, and Colorado, the researchers took sushi samples and were identified as being from as big eye tuna, yellow fin tuna or one of two blue fin tuna species. Burger said, The range of mercury in tuna is very great, so you're taking [a] risk if you don't know what kind of tuna you're eating,”. He also recommends the following , while there aren’t any hard and fast rules when it comes to eating fish , which is also known as health benefits.
