SACO, Maine (AP) — The cause of a rash of seal deaths in Maine and New Hampshire likely won't be known for at least a couple of weeks as sample collections and tests are still needed. Southern Maine beaches have been beset with dead harbor seals in recent days, with dozens washing up stranded or having perished. The National Oceanic and Atmospheric Administration says Thursday sample collections still need to be completed, and then tests will take another two or three weeks or potentially longer.
