Tests conducted on “new” clothing from clothing stores have been found to contain dangerous bacteria in a recent study by Dr. Philip Tierno, director of microbiology and immunology at New York University.
After purchasing items from various clothing stores, Dr. Teirno was alarmed find traces of respiratory secretions, skin flora, and some fecal flora (bacteria). The worst of the items tested was a blouse which held vaginal organisms, yeast and more fecal germs.
"Some garments were grossly contaminated with many organisms … indicating that either many people tried it or ... someone tried it on with heavy contamination," he said. "In a sense, you are touching somebody's arm pit or groin”.
