Dog walkers have been warned to be extra careful with their pets after reports a toxic substance washed up on the Wirral shore.
Despite no confirmed reports of palm oil along the North Wales coastline, the oil which is potentially deadly to dogs, was spotted on New Brighton beach on Easter Monday.
The Wirral Coastguard Rescue Team were called to clear the substance which was found near to the Black Pearl pirate ship.
Palm oil, often found in boulder-size chunks is not dangerous to humans but high toxin levels in animals has damaging effects and leads to vomiting and diarrhoea, and potentially death.
It is thought to come from the Maltese ship Kimya , which capsized 16 miles south west of Holyhead in 1991, killing 10 of its crew.
It was designed to carry chemicals in some of her tanks, as well as vegetable oil and wine in others.
Rescuers spent 12 hours battling “some of the worst seas in living memory” when the ship overturned, and were able to save only two members of the crew.
The 1,800-ton ship was en route to Birkenhead when it got caught in 50ft waves.
However, recent storms in 2017 are believed to have moved the wrecked ship and dislodged palm oil from the ship’s cargo, which ended up at Tyn Tywyn beach in Llanfaelog and Silver Bay in Rhoscolyn last March.
The toxic oil washed up again along a beach near Trearddur Bay for the second time in November.
The chunks of oil smell of diesel and dogs can lick them before becoming seriously ill.
A spokesman for Anglesey Council said the maritime section has not received any reports of palm oil on Anglesey since November.
Gwynedd Council also confirmed it has not received any reports of the toxic oil.
