This much is true — compact fluorescent bulbs (CFLs) contain mercury and mercury is toxic.
Also true — the mercury is sealed in, so you won’t be exposed unless a bulb breaks AND you don’t follow a few simple clean-up steps (below).
This, too, is true — many of America’s favorite food fish are contaminated with mercury from coal-fired power plants. Use less mercury by using energy-efficient CFLs and you will reduce the mercury in our food supply. Meanwhile, use this guide to steer clear of the most contaminated fish.
Finally — watch out for processed foods made with high fructose corn syrup (HFCS), including many yogurts, dressings, condiments and cereals. A recent study found mercury in nearly a third of the products tested, including foods and beverages by Quaker, Hershey’s, Kraft and Smucker’s. You can’t tell from the label which do or do not contain the kind of HFCS made with mercury, so it’s safest to avoid foods made with HFCS altogether. Probably healthier for you anyway.
