Household Cleaners Might Be Ineffective Against Norovirus, Report Says

A recent report has raised concerns over common household disinfectants, warning that many may not effectively eliminate norovirus—the leading cause of foodborne illness in the U.S. As norovirus outbreaks have slowly surged across the country, health officials urge consumers to review their cleaning practices and take extra care, especially during periods of illness.

Studies by a prominent food and agriculture research institute revealed that while disinfectant wipes and alcohol-based hand sanitizers are convenient, they fall short against norovirus. Experts remind us that these products often boast high efficacy rates against many pathogens, but they struggle with norovirus due to its tough protein coat. Unlike some viruses that are more vulnerable once their lipid envelope is disrupted, norovirus’s hardy structure allows it to remain infectious on surfaces for extended periods—even at temperatures as high as 145°F.

The Centers for Disease Control and Prevention has noted a significant spike in reported outbreaks, suggesting that current cleaning protocols might need an update. Health professionals advocate for using stronger agents, such as bleach or hydrogen peroxide-based disinfectants, which have shown better results at neutralizing this resilient virus. For bleach, a recommended solution is to mix ¾ of a cup per gallon of water, ensuring it sits on hard surfaces for at least five minutes. In cases where norovirus contamination occurs on carpeted areas, using a steam cleaner at temperatures above 175°F for a minimum of five minutes can help reduce risks.

These guidelines emphasize the importance of proper sanitation, particularly in areas where food is prepared or where ill individuals have been present. Taking swift action by promptly cleaning contaminated surfaces and discarding potentially tainted food items can help prevent further infections.
