The clam dredge ESS PURSUIT has been ordered to return to port, and its catch isolated, after they discovered 10 mystery containers today while working in Hudson Canyon. One container broke open and exposed two crewmen to the contents. They subsequently developed blisters and difficulty breathing. The crewmen were taken to Massachusetts General Hospital for treatment. The catch from the vessel has been isolated to determine if it was contaminated, and the vessel is being surveyed to see if it needs to be decontaminated. The Coast Guard and U.S. Public Health Services are investigating the incident.
