Dog owners warned of dangerous palm oil ‘fatbergs’ washing up on Irish beach

Dog owners have been warned to keep their pets on a lead while out walking on the beach as palm oil ‘fatbergs’ have washed up on the Irish coastline.

A ‘fatberg’ is a congealed lump of fat, and these particular ones are thought to be a result of a palm oil consignment that slipped off a ship into the English Channel about 18 months ago.

They are potentially harmful to dogs.
