Poisonous plants
Poison ivy
Plants that are poisonous to humans may also be just as harmful to pets and animals. A review of the available literature has shown that problems exist for doctors who have to diagnose and treat cases of plant-induced poisoning in Ontario. The initial problem is in determining whether the symptoms are indeed caused by plant toxins. The second is in acquiring a positive identification of the plant involved. In addition, well-documented literature is often not available on previous cases of poisoning and treatment. Regional Ontario Hospital control centres present in various areas of Ontario are the best sources of information. For further information, consult your family doctor or your local Ontario Hospital Poison Control Centre. |
