Dog walkers visiting the Suffolk coast are being reminded to take extra care following further reports of palm oil washing up on the shore and the ongoing shellfish poisoning risk.
Suffolk Coastal and Waveney district councils issued the advice after receiving more calls about palm oil along the coastline.
Palm oil is not poisonous but can cause illness if ingested in large amounts.
The councils also urged pet owners to take precautions against paralytic shellfish poisoning (PSP) - a naturally occurring toxin, which has caused several pet deaths in the region.
A spokesman added: 'There is no risk to people or pets from the seawater - the only risk is from ingesting PSP-contaminated animals found on the beach.
'Dog walkers are advised to take precautions to prevent their pets from eating anything found on the beach.
'This may include keeping dogs under close control, on leads or muzzled if considered appropriate, while walking along the coast.'
