A warning has been issued to dog walkers after reports of ‘Poisonous Parsnips’ or ‘Dead Man’s Fingers’ at the beach.

The official name is Hemlock Water Dropwort Roots and is extremely toxic.

A spokesman for Whitehaven Coastguard Rescue Team said: "We are aware of reports circulating on social media of potential Hemlock Water Dropwort Roots having washed up on St Bees beach.

"We would urge dog owners to be extra vigilant and not to touch these items.

"This is not a matter for HM Coastguard, we have consulted the Environment Agency who have advised that any findings of this nature would need to be reported to Copeland Borough Council.

"The plant, Hemlock Water Dropwort, more widely referred to as ‘Poisonous Parsnips’ or ‘Dead Man’s Fingers’, is relatively common along parts of the UK coastline, however, the roots which look similar to a parsnip are extremely toxic to both animals and humans.

"It is possible that recent stormy weather and tidal surges may have unearthed and uprooted these plants, then they have been washed ashore.

"If you think your dog may have come into contact or ingested any ‘poisonous parsnips’ it is advised to seek veterinary assistance as soon as possible.

"These plants also pose health risks to humans if physical contact is made so caution is advised at this time."
