Indirect contact with the allergenic oil in poison ivy, oak, and sumac can occur from contact with:

• Sporting equipment, such as fishing rods, balls, baseball bats and gloves, and hockey sticks.
• Lawn and gardening tools, such as lawn mower handles, rakes, and gardening gloves.
• Clothing and shoes, such as gloves, pants, or footwear that have brushed against the plant.
• Pet fur. Although animals do not get a rash when they are exposed to poison ivy, they can carry the oil on their fur, where it may be spread to people who pet them.
