Could Household Bleach Raise Kids' Risk for Flu, Other Infections?
Could Household Bleach Raise Kids' Risk for Flu, Other Infections?

THURSDAY, April 2, 2015 (HealthDay News) -- A ubiquitous cleaning agent in most American homes -- bleach -- might increase children's risk for flu, tonsillitis and other infections, a European study suggests.
The effect was modest and the study couldn't prove cause-and-effect. However, the researchers said that because millions of homes use bleach or products containing bleach every day, the effect on kids worldwide could be significant.
"The high frequency of use of disinfecting cleaning products, caused by the erroneous belief, reinforced by advertising, that our homes should be free of microbes, makes the modest effects reported in our study of public health concern," the researchers wrote.
The study was led by Lidia Casas of the Center for Environment and Health at KU Leuven in Leuven, the Netherlands. Her team looked at more than 9,000 children, aged 6 to 12, in the Netherlands, Finland and Spain.
Those whose parents used bleach to clean their homes at least once a week had higher rates of respiratory and other types of infections. Specifically, Casas and colleagues found that these children had a 20 percent higher risk of having the flu at least once in the previous year, a 35 percent higher risk of recurrent tonsillitis and an 18 percent higher risk for any recurrent infection.
How might bleach boost infection rates? According to the study authors, airborne components of bleach and similar products may irritate the lining of children's lungs, triggering inflammation and making it easier for infections to take hold. Or, bleach may somehow suppress the immune system, making infections more likely, the team said.
The American Cleaning Institute (ACI), which represents makers of bleach and products containing bleach, took issue with the study.
"Since there was no data presented on the children's actual exposure to bleach -- nor any diagnoses of actual diseases -- the authors are merely speculating," the ACI said in a statement. The group also said that disinfecting household surfaces with bleach can protect people from bacterial infection.
And one respiratory disease expert said it's not yet clear that people need to toss out their bottles of bleach.
