What part of wild parsnip is toxic?

▐ Why is wild parsnip dangerous? Wild parsnip sap contains chemicals called furanocoumarins which can make skin more vulnerable to ultraviolet radiation. Brushing against or breaking the plant releases sap that, combined with sunlight, can cause a severe burn within 24 to 48 hours.

What happens if you ingest wild parsnip?

Toxicity. Wild parsnip may have chemicals called furanocoumarins. These chemicals can cause severe sunburn (photosensitivity) in people and animals that eat them and become exposed to UV light (sunlight). Sunburn occurs after ingestion when furanocoumarins are in the blood vessels just below the skin.

Why should you not burn wild parsnip?

Like giant hogweed and other members of the carrot family, it produces sap containing chemicals that can cause human skin to react to sunlight, resulting in intense burns, rashes or blisters.

Do Not Touch This Plant!

Wild parsnip ( Pastinaca sativa) is an invasive plant from Europe and Asia that has become naturalized in North America. It is well suited for colonizing disturbed areas but can also be found in open fields and lawns. Wild parsnip sap can cause painful, localized burning and blistering of the skin.

How to Identify Wild Parsnip

Wild parsnip can grow up to 5 feet tall and has hollow, grooved stems that are hairless. The plant's leaves resemble large celery leaves. They are yellow-green, coarsely toothed and compound, with 3-5 leaflets. Small, yellow flowers are clustered together in a flat-topped array approximately 3-8 inches across.

Preferred Habitats

Wild parsnip can be found growing in a broad range of habitats, especially along roadsides, in fields and in pastures. It is common in the United States and Canada and is widespread in New York. DEC encourages the public to report sightings of this invasive plant to iMapInvasives (leaves DEC website).

Hazards to Human Health

Wild parsnip sap contains chemicals called furanocoumarins which can make skin more vulnerable to ultraviolet light. Brushing against or breaking the plant releases sap that, combined with sunlight, can cause a severe burn within 24 to 48 hours.

Prevent Establishment and Spread

It is important to remove new infestations while they are still small and not well established. When using equipment where wild parsnip is present, make sure to clean it thoroughly before using it again in an area that is parsnip-free. Avoid areas where seed is present to prevent its accidental spread on clothing and equipment.

Control and Management

There are no state or federal programs to remove wild parsnip in New York State because the plant is so widespread across much of New York.

Report an Infestation to iMapInvasives

There are no state or federal removal programs for wild parsnip in New York State, but infestations may be reported to New York iMapInvasives (leaves DEC website) to add to the state's collection of invasive species location data.

Toxicity

When exposed to skin, wild parsnip sap causes phytophotodermitis, or a chemical burn from increased sensitivity to sunlight. The compound causing it in the sap, furanocoumarin, is produced within all the aboveground plant parts including leaves, stems, flowers, and fruits. Essentially, the condition causes a severe sunburn.

Identification

Seedlings: Wild parsnip seedlings emerge from February through April. Seedlings have small ovate leaves at first on long stalks. The seedling leaves are toothed and a yellowish-green color.

Wild Parsnip Identification

Wild parsnip can be identified by its leaves, flowers, and unique stem:

Controlling Wild Parsnip

There are several options for controlling wild parsnip. One is chemical control with an herbicide such as glyphosate. This is an effective solution, but requires you to spot-spray every plant, making it an unrealistic option for those with fields full of wild parsnip. Also note that herbicides will kill all the other plants in the vicinity as well.

How Is It Dangerous?

The sap of wild parsnip is quite dangerous to humans and animals. When skin is exposed to this sap, it becomes hypersensitive to sunlight, usually leading to a painful sun-induced burn-like reaction called phytophoto-dermatitis.

Leaves

Rosettes are pinnately compound, green and shiny, with five to fifteen broad, ovate to oblong leaflets.

Flowers

Flat-topped, broad umbel flower cluster two to six inches wide, with numerous five-petaled yellow flowers.

Seeds

Small (one fourth inch), flat, rounded, slightly ribbed, straw-colored and abundant; takes three weeks to ripen before they can reseed.
