Highly Toxic Plant, Hemlock Water Dropwort, Washes Ashore on Irish Beach

Youghal, County Cork, Ireland – Authorities are warning the public to avoid contact with a highly toxic plant, Hemlock Water Dropwort (Cicuta virosa), discovered washed up on The Mall beach in Youghal. Cork County Council issued an urgent alert on March 14, 2026, advising visitors to exercise extreme caution.

What is Hemlock Water Dropwort?

Hemlock Water Dropwort, sometimes referred to as “dead man’s fingers,” is considered one of the most hazardous plants in the UK and Ireland. It belongs to the carrot family and its roots closely resemble parsnips, posing a potential risk of accidental ingestion. Cork County Council states the plant is naturally occurring in Ireland but is highly toxic.

Risks and Symptoms

Contact with Hemlock Water Dropwort can cause skin irritation. However, ingestion is far more dangerous, potentially leading to fatal poisoning within hours. While cases of adult poisoning are rare – with only 13 recorded in Britain between 1900 and 1970, nine of which were fatal – the plant poses a significant threat to children and pets. The Irish Mirror reports the plant is deadly to both animals and people.

Symptoms of ingestion include nausea, vomiting, seizures, hallucinations, involuntary muscle movements, and haemorrhaging of the brain and lungs.

Council Advice

Cork County Council advises the public to:

• Avoid touching the Hemlock Water Dropwort plant.
• Remain vigilant on beaches in the East Cork area.
• Preserve children and pets away from any unfamiliar plants washed ashore.
• Seek advice from a healthcare professional if contact is suspected.

Cork County Council is continuing to monitor the situation and will take appropriate steps as needed.
