Several popular beaches along the East Coast, spanning from Delaware to Virginia, have been closed due to medical waste, including hypodermic needles, washing ashore. The contamination has led to the closure of beaches such as Ocean City, Assateague Island, and Rehoboth Beach, with authorities advising visitors to avoid the water and wear shoes on the beach. The source of the waste remains unknown, and multiple state and federal agencies, including the U.S. Coast Guard, are investigating. Despite some decrease in waste, the situation is still being monitored, and it is unclear when the beaches will reopen.
