Amazon has yet to confirm or deny if all, or any, "Sold by Amazon" product is commingled with 3rd party FBA product. In that sense, they are not 100% safe. I really wish Amazon would take a stance here.

On the other hand, the vast majority of report of counterfeit anecdote I have seen indicated they bought from 3rd party but with FBA. So me personally I still place trust on Sold By Amazon product.

More recently I have seen product where that explicitly points out that Sold By Amazon is "authentic", which is kind of funny and sad. (energizer battery)
