Shrimpers who were exposed to a mixture of oil and Corexit dispersant in the Gulf of Mexico suffered severe symptoms such as muscle spasms, heart palpitations, headaches that last for weeks and bleeding from the rectum, according to a marine toxicologist who issued the warning Friday on a cable news network.

 

Dr. Susan Shaw, founder and director of the Marine Environmental Research Institute, said during a CNN broadcast that after personally diving the oil spill in late May, a “very fiery sore throat” plagued her from inhaling fumes coming off the water. Because she was covered from head to toe in a protective suit, Dr. Shaw was spared direct exposure.

 

Shrimpers who had bare-skin contact with the mixture of oil and Corexit, she said, were not so lucky.
