WEST TISBURY/OAK BLUFFS (CBS) – Several Martha’s Vineyard beaches have been shut down over bacteria concerns.

According to the town of West Tisbury’s website, Lamberts Cove, Seth’s Pond, Salt Works Seven Gates, Long Cove Pond, Long Point @ the Ocean and TTOR Tisbury Great Pond are all closed until further notice.

In neighboring Oak Bluffs, officials there shut down Inkwell Beach, Pay Beach, Eastville Beach, Drawbridge (Lagoon Side) and Medeiros Cove.

Recent bacteria tests discovered high levels of enterococci, which is found in sewage.

Health officials say they will continue testing and reopen the beaches when bacteria counts return to safe levels.
