Experts operating states apart confirm toxic content in not just shrimp, but crab and fish too, Raw Story, November 10, 2010:
Dr. William Sawyer... said... "We found not only petroleum in the digestive tracts [of shrimp], but also in the edible portions of fish.
"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."
The FDA says up to 100-PPM of oil and dispersant residue is safe to consume in finned fish, and 500-PPM is allowed for shellfish.
Dr. Sawyer, who has long been a vocal critic of these rules, called the government's tests "little more than a farce."
