Usually when you at a restuarant, you expect you sushi to be safe and poison-free? Wrong! After reading Livescience.com's article, you will end up watching what your eating now. A new static says that it is safter to eat tuna from a grocery shop than from a restuarant. However, that doesn't mean a thing compared to other fishes. In fact, tuna is probably one of the highest edible mercury fish. Listen up as you read my blog!
SUSHI DNA:
Previous studies shown before say that there is a few diffrent mercury levels for each fish. These studies isn't reliable because they didn't have a good method for seperating the tunas. As you can see, there is a new way to determine a type of salmon. It's called DNA barcoding. In this method, scientists use a "species's fingerprint" and compare it to an unknown species. This comes in handy since some of the markets or restuarants don't even know what type of tuna they're selling! This show that some markets or restuarants could be giving you some bad fish...
However, which one gives you the better fish more?
THE EXPERIMENT:
The reseachers for this experiment took 69 samples of tuna from restuarants and markets. 54 from restuarants and 15 from supemarkets... The mercury levels were much higher than your average fish. In fact, the tuna, bluefin akami broke had a higher mercury level allowed by the USA Food and Drug Administration:
THE HEALTH RISKS:
The mercury level rises in the food chain. For example, a fish that is a predator, has a higher
mercury level. If you eat mercurary, the risk are disabilities and other serious problems that can't be fixed.
