Can you get poison sumac rashes by touching something that touched sumac?

Yes, it is possible to get a poison sumac rash by touching something that has touched sumac, even if you do not directly touch the plant yourself. This is because the oils that contain urushiol, the substance that causes the rash, can be transferred from one surface to another. Therefore, if you come into contact with anything that has come into direct contact with poison sumac, such as clothing, tools, or even the fur of an animal, you may still develop a rash. It is important to take precautions to avoid direct or indirect contact with poison sumac and to promptly wash any exposed surfaces to minimize the risk of developing a rash.
