What palm trees spikes are poisonous?

Palm trees can be dangerous if you touch them in the wrong spot. Sharp thorns on their branches, trunks and the undersides or tips of fronds can puncture the skin and cause bacterial or fungal infections. Puncture injuries may look harmless, but bits of thorny debris may lodge inside the wound. Infections are particularly likely if the debris carries fungal toxins or soil bacteria, such as Pantoea agglomerans. Inflammation of a palm tree puncture wound requires medical treatment.
