Council officials have warned beach users to be vigilant over the next few days after a toxic substance washed up on a number of Kent beaches.

The deposits of palm oil, which first came ashore yesterday in Folkestone, can be toxic to animals and can poison dogs.

It has not yet been found on any beaches in the Canterbury district, but city council bosses have today told residents to be on their guard.

The authority posted a statement on Facebook, saying: "Deposits of palm oil – which can be toxic to animals if eaten – have been seen on some beaches in the south east.

"The deposits are a waxy substance and are yellowish/white in colour.

"Our foreshore officers are out and about inspecting our beaches this morning. Please be vigilant if you are using the coastline over the next few days."

The lumps have today been seen on all of Thanet's beaches.
