Precaution principle exists, and in the case of food safety, "getting new data" make take years or be very costly.

For instance, bisphenols in plastics baby bottles were proved problematic after decades of use. Precaution principle would have recommended to avoid them (especially since they weren't necessary).

It's not trivial, and many businesses would rather see their consumers die than cut their margins. I remember buying some custom furniture; when it arrived it reeked of varnish smell. I called the factory, told them they didn't cure it correctly. Manager said "yeah we know, we know it's dangerous but people get cancers years later and you can't identify the source anyway" (true story).
