Good seafood can be dangerous

Fish, shrimp, scallops and other seafood is considered to be very useful for health food. But the study by researchers from the United States finished an unexpected verdict: Scientists have advised lovers of seafood reconsider its menu and abandon the usual dishes.

The authors of the new work, the staff of the University of Oregon, argued that the seafood is not as useful as it is often said, and the regular use of such products may damage health.

The harm from eating seafood, scientists associated with ocean warming. According to the researchers, the global ecological process leads to an increase in the amount of toxic compounds in the inhabitants of the deep sea.

In particular, US clinicians prove the connection between the water temperature in the ocean conditions and the level of domoic acid - strong toxin which maintains its properties even after heat treatment. In tepleyuschey water algae activity is enhanced, leading to an increase in the level of this toxin in the water bodies, health workers say.

Domoic acid enters the body of many marine species - clams, crabs, shrimp, scallops, some species of fish (sardines, anchovies). In this toxic component is a long time to accumulate in them, warn experts.

They admit that the toxin may have serious adverse effects on human health. "This neurotoxin enters the marine food web and as a result is absorbed by shellfish, such as anchovies, mussels, oysters and scallops. High levels of domoic acid have been associated with mass mortality of marine mammals such as sea lions, sea otters, dolphins and whales, "- noted with concern the authors of the work.
