New submitter daleallan writes "Triclosan, which is widely used in consumer handsoaps, toothpaste, clothes, carpets and trash bags, impairs muscle function in animal studies, say researchers at UC Davis (abstract). It slows swimming in fish and reduces muscle strength in mice. It may even impair the ability of heart muscle cells to contract. The chemical is in everyone's home and pervasive in the environment, the lead researcher says. One million pounds of Triclosan is produced in the U.S. annually and it's found in waterways, fish, dolphins, human urine, blood and breast milk. The researchers say their findings 'Call for a dramatic reduction in use.' It's in my Colgate Total toothpaste, and in fact, preventing gingivitis is the only use that may be worthwhile, although this makes me think twice about continuing to brush with it." This isn't the first time Triclosan has been in the news over safety concerns.
