The whale carcass, which drew sharks and onlookers to the busy metropolitan beach, was finally taken to Red Hill tip on Thursday after washing ashore days earlier. On Monday, the Town of Cambridge announced all beaches within its boundaries would remain shut for another 24 hours following water samples taken at the end of the previous week.
The samples revealed high levels of E. coli bacteria at City Beach, City Beach North and Floreat Beach. Officers returned to the beaches on Monday for further testing.
A Town of Cambridge spokesperson said the community had been asked not to enter the water at any of the local government's beaches and to keep dogs out of the water as well.
"While the Town undertook water sampling as a precautionary measure, we did not expect the water sampling undertaken following removal of the whale carcass to return these unusual results," the spokesperson said.
