Castor bean plant next to edible trees?

[WaterFowler]

My gf planted a small 8" plant in February next to a 6 foot Sapodilla tree and some Thai pepper plants. I didn't realize what it was until it it had gained some size. It's now 4 feet high with leaves bigger than dinner plates.

I figure it would be good for providing afternoon shade for the Sapodilla during our brutally hot summers but I'm concerned about the toxicity of the Castor Bean plant because every part of the plant is toxic from what I understand. Do you think it's dangerous to plant edible trees next to toxic ones?

It should not be dangerous to the fruit tree as far as poisons.
some places actually use the left-over bean husks as compost.
