Safety of growing food under Jacaranda trees

Maybe this is stupid to ask, but I'm trying to grow organic produce in patio containers, which are under several Jacaranda trees.
The trees keep dropping leaves, flowers and seeds into my containers and I can't pick them all out.
So, are the foods safe to eat if there are lots of Jacaranda tree parts in the soil?
Obviously I'm new at this, but heard that all parts are poisonous and wasn't sure if these poisonous substances will transfer to the foods I'm growing.
Thank you.
