Antibacterial wipes which have become increasingly popular in many homes, nursing homes, schools and hospitals, may not it seems be the answer when it comes to getting rid of dangerous bacteria.
In fact according to new research they may even do more harm than good.
A team of researchers at Cardiff University in Wales suggest such wipes may not be the ultimate answer in hygiene and might even spread, rather than kill, bacteria.
The researchers from the University's School of Pharmacy conducted tests on the effectiveness of three different types of antibacterial wipes containing either traditional disinfectants, detergents or natural antimicrobial substances extracted from plants.
The team led by microbiologist Dr. Gareth Williams used the wipes to clean surfaces that had been severely contaminated with notorious bacteria including the "superbug" MRSA (Methicillin resistant Staphylococcus aureus).
MRSA has become an increasing worry in many hospitals in the developed world and a community acquired version is also causing concern.
The study found that natural antimicrobial wipes removed the most bacteria from surfaces, while disinfectant wipes did the best job of killing bacteria.
However the researchers also found that all of the dirty wipes, including those with the disinfectant, still had some bacteria remaining on them and when they were reused, the wipes just transported the bacteria to another location.
Dr. Williams says ideally the wipes need to kill what they remove and he recommends that one wipe is applied in one application to one surface, and then discarded which would possibly prevent the transfer of bacteria to different surfaces.
For the study, conditions in the bacteria-filled environment of a hospital intensive care unit (ICU) were established, where as a rule the levels of potentially dangerous bacteria are controlled by disinfection where as many microscopic bacteria as possible are removed.
Experts say disinfection differs from sterilization in that it is not designed to kill all organisms, but rather to simply reduce the number of organisms on a surface.
