Mercury Poisoning

Mercury is a metal that occurs naturally in small amounts in the environment. Mercury exists as a liquid, solid and gas and can be highly toxic if inhaled. 

Mercury can be found in:

  • Thermometers (those with a silver liquid contain mercury, those with a red or blue liquid do not contain mercury)
  • Compact Fluorescent Lightbulbs
  • Thermostats and barometers  
  • Manual blood-pressure devices  
  • Some gas meters (mostly meters installed before 1961, which contain mercury-containing regulators)

Due to mercury content in fish, the U.S. Food and Drug Administration and the U.S. Environmental Protection Agency (EPA) have recommended that pregnant women eat no more than two six-ounce servings per week of low-mercury fish, such as shrimp, canned tuna, salmon, pollock and catfish.
