Dog walkers have been warned after "toxic" shellfish washed up on beaches.

The signs were put in place over the weekend following stormy weather and high spring tides.

Lots of molluscs still in shells have been washed up on beaches, including Scratby and California.

Over the past week, strong winds and high spring tides have battered the eastern coastline of Norfolk.

This has left homes in Hemsby perilously close to the cliff edge due to an eroding coastline, with some having to be bulldozed. 

Gale-force winds have been battering Norfolk today, with gusts of up to 65mph reported in some areas.

A Met Office yellow weather warning is in place until 6pm today (March 13). 

Symptoms of Paralytic Shellfish Poisoning

Symptoms usually develop in humans within 30 minutes, according to the Eastern Inshore Fisheries and Conservation Authority (IFCA).

Symptoms include:

  • Tingling/burning sensation followed by numbness in the lips, tongue and face which progresses to extremities.
  • Paralysis of limbs, loss of muscle coordination and constrictive sensation in the throat.
  • In high doses, paralysis can extend to the respiratory system, affecting breathing.
  • Other symptoms exhibited in dogs exposed to toxins have included vomiting, reduction in movement, difficulty walking and/or standing and loss of consciousness.
