Dog owners in Southampton have received a warning from authorities after palm oil washed up on Weston Shore.
Although not harmful to humans, palm oil can kill dogs and owners have been urged to keep pets on leads around the area for the foreseeable future.
The palm oil is currently being found in the form of white, chalky lumps, slightly smaller than a rugby ball, and gives off a sulphur smell.
Anyone who find any has been asked to either contact their local council or dispose of it safely.
Hampshire fire service advised: “Wear double vinyl gloves and place in a strong plastic bag over the substance and bag it up, place the outer gloves in with the oil, tie it off, then place into a second strong bag and also tie off.”
“This can be disposed of in ordinary refuse.”
Dog owners in Cornwall have also been told to look out for the palm oil, which is currently killing “a dog a day” along the county’s beaches.
