The Centers of Disease Control (CDC) just announced:
For the seafood to pose a health risk, the food would have to be heavily contaminated with oil, and would therefore have a strong odor and taste of oil.
That is patently untrue.
As I pointed out in June:
Crude oil contains such powerful cancer-causing chemicals as benzene, toluene, heavy metals and arsenic.
As Bloomberg notes:
“Oil is a complex mixture containing substances like benzene, heavy metals, arsenic, and polynuclear aromatic hydrocarbons -- all known to cause human health problems such as cancer, birth defects or miscarriages,” said Kenneth Olden, founding dean of New York’s CUNY School of Public Health at Hunter College, who is monitoring a panel on possible delayed effects.
Corexit breaks oil down into its constituent chemicals. So there could easily be toxic levels in the compounds that don't smell anything like oil.
For example, arsenic is odorless. So fish contaminated with arsenic will not smell or taste like oil.
