Beaches in Delaware, Maryland and Virginia announced they were closed to swimmers Sunday due to medical waste that washed ashore.

Sixty state and federal agencies are working busily to try to contain an onshore wash of medical waste over the weekend along the coastline from Delaware down to Virginia.

Rehoboth Beach announced its closure to swimmers on Monday, joining Dewey Beach and Fenwick Island after medical waste began washing ashore Sunday, though a news release from the city said the closure is "primarily due to rough surf conditions."

Many beaches in Delaware have been closed to swimming since Sunday, September 15th when medical waste began washing up on the beaches. DNREC's swimming/wading advisory is through Sept, 23. Wearing closed-toe shoes to walk on the beach is advised.

Fenwick Island has released new information regarding beach conditions and medical waste that has been washing ashore on along the eastern shore. At this time no medical waste was found during the last few days of inspection.
