I have a mild fish allergy. Would it be safe for me to take krill oil? Should I be worried about fish contaminants? I am not allergic to shell fish.

See an allergist. Not sure what a mild allergy is, you can either develop an allergic reaction from fish or not and you should not risk an anaphylactic reaction if you are truly allergic. Best is to consult an allergist for proper advice about your fish allergy.
