Yes of course it is in their interest to lie / hide until it becomes public knowledge. But regulation has the exact same problem (hence why Asbestos was not regulated for a long time, same with your other examples).
When it is widely known (and therefore can be regulated) it is already too late as it's now in the producers interest to cease producing it.
Heavy litigation after the fact can disincentivise the lying in the first place. If legislation doesn't not allow for this (e.g. because of time limitations) then it should be amended.
