title: Blood mercury levels and fish consumption in Louisiana.
abstract: The primary source of non-occupational exposure to mercury is through the consumption of contaminated fish. Since 1994, the Louisiana Department of Environmental Quality has reported mercury contamination in fish obtained from bodies of water throughout the state and has issued fish consumption advisories accordingly. To determine the extent of mercury intoxication in Louisiana, screening for blood mercury levels was offered to volunteers residing near selected advisory areas. A total of 313 residents participated in the screening; 6 were found to have elevated levels. No level was detected in 48 of the participants, while the remaining participants had normal levels. Significantly higher levels were found in those associated with commercial fishing and those reporting increased fish consumption. For most people, ordinary consumption of fish contaminated with mercury does not currently appear to pose a public health hazard in Louisiana; however, educational efforts regarding the risks of fish consumption in great quantities should be continued.
