MUSC researchers say the FDA should reconsider the ammounts of domoic acid that it allows in seafood. The study found it can cause kidney damage in mice.
Charleston, SC (WLTX) -- A study at the Medical University of South Carolina suggests the Food and Drug Administration should revisit what it considers for the acceptable levels of toxins in seafood.
MUSC researchers say they found that the current levels cause damage to kidneys.
The study gave mice varying doses of domoic acid and then assessed their kidney health. The group concluded that those who consume seafood may be at an increased risk of kidney damage, which can lead to kidney failure and dialysis.
Domoic acids leaves the body through the kidneys. According to MUSC, the FDA acceptable limit of domoic acid in seafood is currently based on research into how it impacts the brain, not the kidney.
MUSC researchers recommend further study in humans, and say the FDA should reconsider the legal limit of domic acid in food.
Scientists say the warming of the ocean and an increased amount of algae means there is more domoic acid sitting at the bottom of the ocean where it is taken in by the mussels, clams, scallops and fish. They say it used to be more of a West Coast problem but has now become alarming in the Gulf Coast.
