"Should I risk this?" is the wrong question in life. The burden of proof, as it were, is on those who are alleging a risk. I'm not gonna go through life worrying about every little thing just because it might be a problem. That goes double because people are constantly finding new things to worry about, most of which amount to nothing in the end.
Holding its probability constant, if the cost of avoiding a risk is sufficiently low and the potential harm sufficiently high, avoiding it is more rational than both looking further into it or taking it.
That would make sense in a just society. Here in the USA, I would factor evidence in such as, do corporations have a habit of using chemicals that are later shown to be toxic? Do corporations prefer to let people die rather than recall, say an exploding car? Do corporation put out armies of lawyers and doctors to convince everyone that their product does not cause lung cancer? Do corporations now use automation to brigade and create the appearance of a majority?
