Thank you for your question. The following Extension article is the most recent I could find: https://www.extension.iastate.edu/smallfarms/toxicity-concerns-about-raised-bed-construction-materials However, since Penn State has been at the forefront of this research (https://extension.psu.edu/environmental-soil-issues-garden-use-of-treated-lumber), I suggest you contact your county Extension service to check on the status of copper napthenate treatments: https://extension.psu.edu/lancaster-county Good luck!
