"Not shown to be safe" is about the weakest claim that you could make.

> Absolutely not. And the fact that people think that kind of thing after reading sensationalized articles like this causes real problems.

Are you trying to say that this study did show these chemicals to be safe, or were they not shown to be safe? Believing the first would be a real problem.

I suspect the confusion is over the difference between "not shown to be safe" and "shown not to be safe". The former is saying that "we haven't yet determined for sure that they're safe", and the latter states "we've concluded for sure that they are not safe". It's unfortunately super easy to misread one for the other despite their very different meanings; I had to re-read the original sentence twice before being sure that I read it correctly.
