Raw    Story: Experts  operating states apart confirm toxic content in not  just shrimp, but crab and fish too...  
     "We've collected shrimp,  oysters and finned fish on their way to marketplace -- we tested a good  number of seafood samples and in 100 percent we found petroleum."
  
  Multiple independent lab tests  confirm oil in Gulf shrimpIn two separate cases, a toxicologist and a  chemist independently confirmed their seafood samples contained  unusually high volumes of crude oil and harmful hydrocarbons -- and some  of this food was allegedly being sent to market.
  
  One test, conducted by a  chemist from Mobile, Alabama, employed a rudimentary chemical analysis  of shrimp pulled from waters near Louisiana and found "oil and grease"  in their digestive tracts.
  
  Naman also found that the oil  was at an unusual high concentration: 193 parts-per-million (PPM).
  
  "193 parts-per-million of  petroleum in a crustacean is very high," she told Raw Story. "You have  to ask, what is the meaning from a human health perspective?
  
"This is another signal that  oil is in the food chain in the Gulf. Oil has been found in subsea  plumes, in seafloor sediments, where it will degrade very slowly and can  be re-released into the food chain."
