That&#x27;s arguably overkill for domestic contamination by elemental and inorganic mercury. Even that family in that contaminated house was probably at far greater risk from methylmercury[0] in predatory fish. So cutting predatory fish from the diet would have arguably been more cost effective. But it&#x27;s hard to say. CDC[1] is more nuanced on the topic than EPA[2]. And I do tend to trust CDC.<p>[0] <a href="http:&#x2F;&#x2F;toxics.usgs.gov&#x2F;definitions&#x2F;methylmercury.html" rel="nofollow">http:&#x2F;&#x2F;toxics.usgs.gov&#x2F;definitions&#x2F;methylmercury.html</a><p>[1] <a href="http:&#x2F;&#x2F;www.cdc.gov&#x2F;biomonitoring&#x2F;pdf&#x2F;Mercury_FactSheet.pdf" rel="nofollow">http:&#x2F;&#x2F;www.cdc.gov&#x2F;biomonitoring&#x2F;pdf&#x2F;Mercury_FactSheet.pdf</a><p>[2] <a href="http:&#x2F;&#x2F;www3.epa.gov&#x2F;airtoxics&#x2F;hlthef&#x2F;mercury.html" rel="nofollow">http:&#x2F;&#x2F;www3.epa.gov&#x2F;airtoxics&#x2F;hlthef&#x2F;mercury.html</a>
