Poisoning from contact with the sap from bruised plant parts of the poison ivy , poison oak , or poison sumac . Contact may be indirect, such as coming in contact with an animal which came in contact with the plant. The sap can also be found on contaminated clothing, garden tools, and sports equipment such as fishing rods, golf clubs, and so forth. Small amounts of sap can remain under a person's fingernails for several days unless it is deliberately removed by meticulous cleaning. The droplets of sap can even be found on ash from burning the plants.

Expectations (prognosis)

Fatalities are very uncommon. At worst the individual will be very uncomfortable for a while. A secondary skin infection may develop if the exposed areas are not kept clean.
