Pet & Human Safety
People: Toxic to people (low severity)Pets: Not on the ASPCA lists as we read them
Toxic to horses only per ASPCA's oak genus page. Dogs and cats are not covered by that page, so this is not a clearance for them. Acorns and leaves are the poisonous parts per NC State, and acorns can block the gut. Do not treat as pet safe.
PlotAndPetal cannot tell you whether a plant you found can be eaten. Only someone who can see the plant can identify it.
