Would you plant vegetables/fruits or raise animals on land where treated lumber was burned?

Hey all, made a wordy post yesterday and didn’t get any replies. Trying again with a more direct question and less background detail.

If you have an area of land where you would like to plant a garden, fruit trees or raise chickens/goats would you be concerned if you knew lumber was burned there and it may have been treated?

Is there any way to know if it was treated? Would you have soil tested?
