Giant Hogweed detected at beaches near Helsinki but swimming remains safe

At the beaches near Helsingin Pikkukoski, Pakila, and Tapaninvainio, a toxic plant known as Giant Hogweed has been detected. Local authorities assure that swimming at these beaches is not restricted due to the presence of the plant. Experts note that exposure to the plant’s toxins through swimming is unlikely, as the toxins are contained within the plant, and they do not spread if the plant remains intact. The areas where the plant is located have been marked with warning tape and signs.

Giant Hogweed is highly toxic, containing a harmful substance called phytotoxin found in all parts of the plant. Direct contact with bare skin requires the affected area to be washed thoroughly for 10 to 15 minutes. Ingesting any part of the plant necessitates immediate medical attention.

The first report of Giant Hogweed came from a public observation by a city employee. A city gardener discovered the plant while inspecting the beaches, leading to the immediate marking of the affected areas with warning tape, according to Jukka Lundgren, head of the Helsinki beaches team. Nearby coastal swimming spots have also been inspected, but Giant Hogweed has not been found there.

The plant typically blooms from July to August and can grow up to 1.5 meters tall. It resembles Cow Parsnip in appearance and usually thrives in the shallow waters of lush waterways. Efforts to remove the plant will be initiated after the summer. Lundgren emphasizes the need for vigilance in monitoring the growth of Giant Hogweed in the coming years, as it is a persistent and challenging species to eradicate.
