1 INTRODUCTION
The majority of plants grown in gardens are not hazardous to humans or animals. However some
plants and fungi have the potential to be harmful in a number of ways, be they cultivated or wild
forms. Physical risks such as spines, loose branches or sharp twigs will usually be obvious to most
sighted adults, likewise the potential risks from eating plants or breathing in smoke from burning
plant material. The risk of a burn from plant sap – potentially exacerbated by sunlight – or
dermatitis and irritation from contact with leaves may be less apparent. The potential risk to
children is significantly higher. Livestock too can be affected, as can domestic pets and wildlife. It
is the responsibility of gardeners and property managers to prevent avoidable risks from
potentially harmful plants.
2 WHO IS AT RISK?
While staff and volunteers who work with plants on a daily basis may appear at first sight most
exposed to potential harm, it could be argued that they are probably also the most risk aware
already; it is reasonable to expect individuals to exercise proper responsibility for their own safety
however care should be taken to prevent exposure to high risk. Others who must be considered
are visitors in general, and children or vulnerable adults in particular. It must be remembered that
people may have different susceptibilities to the same potentially harmful plant, and that
symptoms and their severity can vary from person to person. Also at risk may be valuable
livestock (horses, cattle, sheep, goats), domestic pets (dogs and cats) and wild birds or insects.
The use of plants for herbal remedies requires specialist knowledge.
