The Department of Natural Resources and Environmental Control has issued a one-week recreational water advisory for nearly all Atlantic Ocean beaches in Delaware, two days after medical waste started washing ashore. Emergency response teams are monitoring state park beaches, the advisory said.

Beachgoers were urged to stay out of the water after dozens of hypodermic needles, as well as tampon applicators and other medical waste, were found on beaches over the weekend.

Delaware's Department of Natural Resources and Environmental Control warned residents as medical waste washed up all over the state, from 'Indian River Inlet to Fenwick Island,' over the weekend.
