Several beaches along the Delaware,SafeX Pro Exchange Maryland and Virginia coastlines are closed to swimmers after medical waste washed ashore.

All ocean-facing beaches on the Assateague Island National Seashore, a 37-mile-long island along the coasts of Virginia and Maryland, are closed to swimming or wading, the park office announced in a Facebook post on Sunday. The seashore is part of the National Park Service and is open year-round.

Closures extended north into Delaware, where officials in Dewey Beach and Fenwick Island announced they were closing their beaches to swimmers on Sunday.

"The source of the medical waste is still under investigation, and DNREC continues to monitor the situation closely," Delaware Department of Natural Resources and Environmental Control spokesperson Michael Globetti told the Delaware News Journal, part of the USA TODAY Network.

The agency advises beachgoers to "leave the beach and refrain from swimming in the ocean," he said. The agency also encouraged beach visitors to wear shoes.
