The chemicals that make up the actual flavour component would probably be the same - for any type of flavour out there, there is only a set amount of chemicals that can imitate or reproduce a certain flavour, but they might add all kinds of nasty stuff to make the flavour easier to work with or to cut costs - and they wouldn't care if the stuff they added was harmful to humans, because it is not meant to be used by humans. So for them it would be perfectly fine to add boat loads of Diacetyl for instance.
So that would be your risk - unless you can get a detailed list of all the chemicals in the flavouring, you just would not know - and the detailed list of chemicals that make up the formula would probably be proprietary information - it's their 'secret' formula that attracts the most fish, so I doubt the company would divulge that information to anyone that asks
