Is there a way to determine if a specific food product is more likely to be exposed to pesticides? I love crystallized ginger and I'd like to find out if ginger root from Thailand might not be safe in that regard. I have a hard time finding ginger root from Australia.

Thanks for any info you might be able to give!
