Plants and mushrooms (fungi) poisonous to people
This section of the website contains descriptions and photos of a number of local plants and fungi (mushrooms and toadstools) that can be poisonous to people. It is not a complete list. If a poisoning or suspected poisoning occurs contact the Poisons Information Centre without delay.
Some of these plants are grown in home gardens, some grow wild in the forest or field and some are common weeds. They all pose some risk if consumed or, in some cases, handled by people, however the risk varies from species to species. A few of the plants and fungi identified in this website have been known to cause permanent disability or even death in the past, whilst others have only been reported as causing rashes, vomiting or other unpleasant (but not life threatening) reactions. Key Symbols have therefore been used in this website as an indication of relative risk.
Toxicity categories with key symbols




It is important to recognise that toddlers, in particular, may be at greater risk given their habit of tasting everything and their relatively small body size.
This website is based on the publication Plants Poisonous to People in Queensland jointly produced by Queensland Health and the Environmental Protection Agency in August 2005.
