General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
Common ragweed produces highly allergenic pollen. Its presence also raises a prevention issue for the surrounding community.
It can grow in crops, along roads and in ground disturbed by construction work.
Moving contaminated soil or seeds and using some machinery can spread it. Avoid moving a suspected plant on your own initiative.
For a report, record the exact location and take photographs without handling the plant; these can help someone verify its identity.
Anses recommends locally coordinated control, including a ragweed contact person. Ask the municipality which reporting route applies.
Sneezing and irritated eyes cannot identify the responsible pollen on their own. Describe exposure dates and locations to a health professional.
