Deadly Plant Washing Ashore And What You Need to Know
Recent storms and changing tides have led to a toxic plant known as Hemlock Water Dropwort (Oenanthe crocata) - sometimes called Dead Man’s Fingers - washing up on beaches and coastal areas around the UK. This plant is one of the most poisonous native species in Britain and has prompted public safety warnings from coastguards and local authorities.
Why It’s Dangerous
• All parts of hemlock water dropwort are highly toxic, especially the white, parsnip-like roots that may now be found on shorelines after being uprooted by heavy weather.
• The toxin (oenanthotoxin) attacks the nervous system and can lead to convulsions, paralysis and even death in humans and animals if ingested.
• Symptoms can appear within 30 minutes to a few hours, and there is no specific antidote.
What to Do (and Not to Do)
✔️ Do keep children and pets close and under control on beaches and riverbanks.
✔️ Do report sightings to local authorities so they can arrange safe removal.
✖️ Do NOT touch, pick up, or ingest the plant. Even touching and then eating without washing can cause severe illness.
✖️ Do not try to dispose of it yourself. Leave that to trained professionals.
Enjoy our coasts safely - always stay aware of what’s washing up, and when in doubt, steer well clear.
