But if a fish oil medicine had those issues, I would be shocked, because the consequences for the guilty party would be much bigger, a huge circus of lawsuits and people losing their licenses. That's how I imagine it anyway.

(though I understand a bit of the issues behind the BRCA gene testing thing and I'm not sure it continues to be banned or merely the results need to be more generic and not just "you have X% of having cancer")
