This is not self-evident. Biology is extremely complex and we have a lot left to learn before we can make definitive statements about safety. This idea of 'you can be sure we'd hear about it' places too much of the burden on journalists, random medical researchers, and eventually regulators to suss out what is going on.

As it stands in our system today any awareness we may have about dangers will come far after the danger to us, and then we'll all say a collective 'oops' as we've had to do the last hundred times. Look no further than all the 'I [live near the plant/play on the field/drink the water] and have [cancer/autoimmune/rare disease/etc]' stories that keep coming out year after year.
