LAST UPDATE | 12 Feb

A WARNING HAS been issued over the appearance of hemlock water dropwort – a highly poisonous flowering plant – on beaches along the coast in both Dublin and Meath.

Hemlock water dropwort, sometimes known as ‘dead man’s fingers’, is one of the most toxic plants in Ireland. It is poisonous to animals and humans.

Meath County Council said there have been reports of possible sightings of the plant washing up on Bettystown and Laytown Beach.

There have also been reports that a dog needed veterinary care after coming into contact with the plant in Loughshinny, in north Co Dublin.

Dublin City Council has since said it is aware that hemlock water dropwort has washed up on Dollymount Beach, Bull Island.

The council called on the public to remain vigilant when visiting beaches in the Dublin area and to ensure children and pets avoid touching the plant.

The roots of the plant are highly toxic and can look similar to a parsnip.

The public has been warned not to touch or handle the plant and even brushing against it may cause skin irritation.

Ingestion of any part of the plant can be fatal, causing vomiting, seizures, and respiratory failure within an hour.

Touching the plant can cause skin irritation, painful dermatitis, or rashes, while contact with the sap can cause severe skin blistering. Toxins can also potentially be absorbed through open wounds, or the eyes, nose, or mouth.

Hemlock water dropwort grows in damp grassland and wet woodland, often along river and stream banks. The roots of the plant – the most poisonous part – can wash up on beaches after storms.

“Don’t touch anything that looks like a parsnip‑shaped root washed up on the beach. Keep pets and little ones close. If you spot something unusual, let Meath County Council know,” said a spokesperson.

The council said that due to recent high tides, winds, and swollen rivers, it’s likely the plants were uprooted from their usual habitats along the banks of waterways and shoreline.

“Please stay alert on your coastal walks. Please continue to enjoy our beaches but stay safe and stay aware!” it said.
