This commonly used item is 58 times dirtier than a public toilet seat

That’s gross.

It’s hard to believe that there is something dirtier than a public toilet bowl — but there is, and it’s something that travelers use several times a year.

The wheels of a suitcase are a breeding ground for bacteria, carrying nearly 58 times more than the place where people publicly relieve themselves, according to a study conducted by insurance company Insure and Go.

Insure and Go partnered with microbiologist Amy-May Pointer to swab the wheels and the base of both hard and soft-shell suitcases at an airport train station.

Their findings revealed that several different types of bacteria live on the majority of travelers’ suitcases — Staphylococcus species, which is a common skin bacterium, Serratia marcescens, usually found in bathrooms and Aspergillus species, which are described by the research team as “black fuzzy molds.”

”The microbial communities found on the suitcases included skin bacteria, environmental moulds, and some faecal-associated germs amongst others,” said Pointer, according to Insure and Go.

Most of these organisms are not highly dangerous in everyday settings, but they form a film of general filth. This explains that grimy feel or musty odour luggage can get after multiple trips.”

Now, knowing this, think of all the places that your suitcase, which has been carrying around all this gross bacteria, has touched. Gross.

“The key point is that microbes were very diverse, reflecting all the places the luggage had been. It reinforces the recommendation to keep luggage away from clean surfaces like beds and to deep clean it occasionally,” the expert advised.

To clean a soft or hard-shell piece of luggage, the Wire Cutter team recommends wiping it down with either an alcohol wipe or mixing dish soap with water and using a rag to wipe it clean.

To clean the dirty wheels, first get rid of any hair or carpet fibers stuck using scissors before wiping them down with an all-purpose cleaner.

It’s recommended to clean your suitcase after every trip and “If you want to go the extra mile, consider using a washable suitcase cover, or even slip shower caps over the wheels when bringing it inside,” Pointer suggested.

“It might sound silly, but covering those wheels can stop them from spreading bacteria across your carpet or bedding. You could be protecting your sheets from the kind of microbes that include skin-irritating bacteria like Staphylococcus species.”

Suitcases aren’t the only commonly used bacteria-filled things.

$100 bills have Staphylococcus bacteria, smartphones can carry a variety of bacteria and public toilet seats can contain E. coli growth, according to researcher Amani Abdlrasul, who works as a medical laboratory scientist in Tampa, Florida.
