Antibacterial Ingredients in Indoor Dust Could Contribute to Antibiotic Resistance

In a new study reported in the ACS journal Environmental Science & Technology, for the first time a link between antimicrobial substances such as triclosan in indoor dust and levels of antibiotic-resistance genes, which can transfer from one bacterial cell to another. The overuse of antibiotics in both humans and livestock has largely been blamed for the rise in drug resistance. The ubiquity of antimicrobials in hand soaps, cosmetics and other personal care products that ultimately rinse down the drain and into wastewater has also contributed. Erica Hartmann and colleagues wanted to see whether their presence in indoor dust might play a role, too. The researchers analyzed dust samples from an indoor athletic and educational facility and found six links between antimicrobial chemicals and antibiotic-resistance genes in microbes. For instance, dust samples with higher amounts of triclosan also had higher levels of a gene that's been implicated in bacterial resistance to multiple drugs. Although the median concentration of triclosan in indoor dust was small -- much lower than amounts used in toothpaste, for example -- the researchers say their findings demonstrate the need to further investigate the role of antimicrobials in dust in the rise of antibiotic resistance.

FDA Issues Final Rule on Safety and Effectiveness of Antibacterial Soaps

The Food and Drug Administration (FDA) issued a final rule establishing that over-the-counter (OTC) consumer antiseptic wash products containing certain active ingredients can no longer be marketed. Companies will no longer be able to market antibacterial washes with these ingredients because manufacturers did not demonstrate that the ingredients are both safe for long-term daily use and more effective than plain soap and water in preventing illness and the spread of certain infections. Some manufacturers have already started removing these ingredients from their products. This final rule applies to consumer antiseptic wash products containing one or more of 19 specific active ingredients, including the most commonly used ingredients – triclosan and triclocarban. These products are intended for use with water, and are rinsed off after use. This rule does not affect consumer hand “sanitizers” or wipes, or antibacterial products used in health care settings. “Consumers may think antibacterial washes are more effective at preventing the spread of germs, but we have no scientific evidence that they are any better than plain soap and water,” said Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research (CDER). “In fact, some data suggests that antibacterial ingredients may do more harm than good over the long-term.”

Global Emergence of Invasive Infections Caused by the Multidrug-Resistant Yeast Candida auris

Heallth authorities in the United States and the United Kingdom are alerting hospitals to be on the lookout for an emerging multidrug-resistant yeast in patients that is causing potentially lethal, invasive infections in healthcare settings. First brought to the attention of medical authorities in 2009 in Japan, outbreaks of Candida auris infections have now occurred in nine countries on four continent.

The Centers for Disease Control and Prevention (CDC) in the U.S. and Public Health England (PHE) in the U.K. have issued alerts to hospitals and testing labs warning that healthcare facilities in several countries have reported that C. auris has been causing severe illness in hospitalized patients.

The Transition from Custom Ultrasonics Endoscope Disinfectors

"The FDA recommends that health care facilities currently using Custom Ultrasonics AERs transition away from their use to alternative reprocessing methods as soon as possible. Facilities are advised to identify and transition to alternate methods to reprocess flexible endoscopes, such as manual high-level disinfection, liquid chemical sterilization, alternative AERs, or other cleaning and sterilization methods according to the endoscope manufacturers’ reprocessing instructions."
