In order to protect Canadians from mercury poisoning, a guideline of 0.5 parts per million, or 0.5 micrograms (1 microgram = one millionth of a gram) of total mercury per gram of fish tissue (ug/g) has been established by Health Canada for most commercial fish. Thirty-nine years later, 2 252 patients had been officially diagnosed with Minamata disease, and over 1 000 had died. Fish can accumulate mercury in their muscles through absorption from the surrounding water but mostly from the prey that they eat.

The severity of mercury's toxic effects depends on the form and concentration of mercury and the route of exposure. Exposure to elemental mercury can result in effects on the nervous system, including tremor, memory loss and headaches. When an individual is exposed to mercury, a certain percentage is absorbed, depending on the route of exposure and the form of the mercury. Province-wide advisories are in effect in New Brunswick and Nova Scotia while other provinces have advisories for specific lakes and/or species. Vapour from liquid elemental mercury and methylmercury are more easily absorbed than inorganic mercury salts and can cause more harm. Mercury is deposited in hair as it grows, and it may also be found in breast milk.

Health Canada’s 1996 Position Statement on Dental Amalgam assessed, however, that there was not sufficient evidence to support a ban on the use of amalgam fillings or the removal of sound amalgam fillings in patients who have no indication of adverse health effects attributable to mercury exposure [10]. Exposure to mercury – even small amounts – may cause serious health problems, having toxic effects on the nervous, digestive and immune systems, and on lungs, kidneys, skin and eyes; and it is a threat to the development of the child in utero and early in life.
