A few weeks ago, do antibacterial lotions kill good bacteria FDA announced a bold new position on antibacterial soap: Their reportthe product of decades of research, notes that the costs of antibacterial soaps likely outweigh the benefits, and forces manufacturers to prove otherwise.
Manufacturers have until to do so, or pull their products from the shelves. Antibacterial soaps are no more effective than conventional soap and water. As mentioned in the announcement42 years of FDA research—along with countless independent studies —have produced no evidence that triclosan provides any health benefits as compared to old-fashioned soap.
But the FDA wants data that show that this translates into an actual clinical weight lifting and diuretics, such as reduced infection rates. This might be due to the fact that antibacterial soaps specifically target bacteria, but not the viruses that cause the majority of seasonal colds and flus. Antibacterial soaps have the potential to create antibiotic-resistant bacteria. Heavy use of antibiotics can cause resistancewhich results from a small subset of a bacteria population with a random mutation that allows it to survive exposure to the chemical.
If this happens on a broad enough scale, it can essentially render that chemical useless against the strain of bacteria. This is currently a huge problem in medicine—the World Health Organization calls it a "threat to global health security. Health officials say that further research is needed before we can say that triclosan is fueling resistance, but several studies have hinted at the possibility.
The soaps could act as endocrine disruptors. If this is the case in humans, too, there are worries that it could lead to problems such as infertility, artificially-advanced early puberty, obesity and cancer.
The soaps might lead to do antibacterial lotions kill good bacteria health problems, too. Scientists speculate that this could be a result of reduced exposure to bacteria, which could be necessary for proper immune system functioning and development.
Another study found evidence that triclosan interfered with muscle contractions in human cells, do antibacterial lotions kill good bacteria, as well as muscle activity in live mice and minnows. A survey, for instance, found triclosan in the urine of 75 percent of people tested. Antibacterial soaps are bad for the environment, do antibacterial lotions kill good bacteria.
When we use a lot of triclosan in soap, that means a lot of triclosan gets flushed down the drain. Research has shown that small quantities of the chemical can persist after treatment at sewage plants, and as a result, USGS surveys have frequently detected it in streams and other bodies of water.
The chemical is also fat-soluble—meaning that it builds up in fatty tissues—so scientists are concerned that it can biomagnifyappearing at greater levels in the tissues of animals higher up the food chain, as the triclosan of all the plants and animals below them is concentrated. Outside of hospitals, though, the CDC recommends the time-tested advice you probably heard as a child: But a simple hand wash should do the trick.
