The way to tell how badly fish and foodstuffs are contaminated by the Polley disaster is instead doing an exposure assessment using food safety guidelines for the contaminants of concern: e.g. arsenic, selenium, lead, nickel, etc.
So one would assess the amount of contaminants in fish, and look at total yearly consumption rates - look at contaminants in blood and fat and flesh - and compare those values to established benchmarks. See: http://publications.gc.ca/collections/collection_2012/sc-hc/H128-1-11-641-eng.pdf An example of such a completed exposure assessment can be found at: http://www.unbc.ca/sites/default/files/assets/chan/ste_2005_oostdam.pdf
This methodology is VERY different than spouting that water quality were maintained - and I am VERY sure that the regulators and the associated provincial communications branch and PR firms VERY well know the difference. It looks like the First Nations Health Authority scoped-out the potential impacts - but didn't follow through with a similar scientific exposure assessment at: http://www.fnha.ca/Documents/FNHA-Mount-Polley-Mine-HIA-SSP-Report.pdf
Preliminary fish testing results from 2014 were listed at: http://www.fnha.ca/about/news-and-events/news/mount-polley-mine-communique-8
Looks like no follow-up tests were posted - if done.
