I keep seeing folks claim that the FDA approved the usage of AO in Vietnam and elsewhere in SE Asia therefore we shouldn't trust the FDA approval of the current Covid vaccines. The USDA in was established in 1862 and the FDA in it's current capacity in 1906. The EPA wasn't created until 1970 so they weren't involved in AO approval whatsoever. I can find nothing that states that the FDA tested 2,4-D and 2,4,5-T on test animals or humans prior to it's usage or actually any FDA involvement. I don't think the FDA has ever or will ever test herbicides on humans lol. Anyone have any other info or links on FDA involvement with AO? Thanks.
