Residents have reported the toxic plant Hemlock, which is highly toxic to dogs and humans, to North Ayrshire Council after it was observed on local sands.
Following ex-Hurricane Ophelia, the hemlock dropwart was spotted on Largs beach on Wednesday, and it looks like parsnips or carrots.
Carol Ann McCaffrey alerted North Ayrshire Council to the matter after she spotted the hemlock on shore.
One dog died and another became seriously ill in Cardross after eating roots of the plant following a tidal surge a few years ago.
The plant — hemlock water dropwort — is common along the Ayrshire shoreline in places such as Seamill and Portencross and on the coastal area north of Largs.
The roots of the plant, which bear a resemblance to parsnips, are extremely toxic, both to animals and humans and should be left alone.
It is not thought that any dogs have been affected in the Largs area, but vets are warning owners to be aware of the dangers posed by letting pets eat any unidentified items on beaches or elsewhere."
Should any members of the public be concerned about any hazardous vegetation being washed up, contact North Ayrshire Council on 01294 310000 with details on the item and its location.
Any sightings will be investigated by the Council’s Streetscene Team to identify the plant species and take the appropriate action.
