Anyone who fears they, or their dogs, have come into contact with any dead starfish should get them to a vet and show them the following IFCA advice.

An Inshore Fisheries statement read: "EIFCA have been made aware that strong winds have led to several mass stranding of marine fauna along the Norfolk and Suffolk coasts recently.

"It is important to know that some stranded species, in particular types of starfish, may contain paralytic shellfish toxins (PST) toxins that could be harmful to humans and dogs if consumed.

If you plan to walk your dog on your local beach, please keep them on a lead and ensure they do not consume any stranded animals.

"If you suspect that your dog has consumed stranded fauna and is feeling unwell, please contact your local vet immediately and provide them with the following:
