The uncomfortable fact here though (for you) is that there is precisely zero evidence that this modified salmon is any less safe than other wild or farmed salmon.  Also, if you understood the science, you would know that there is no rational reason (either from evidence or in theory) to fear eating this fish. 

There is neither  evidence nor a scientifically accurate theory that supports the notion that this fish is not safe.

If you don't want to eat it, that's fine.  But recognize that you are doing so because you fear what you don't understand.
