Student wears unwashed jeans for 15 months!

Washington: It looks like wearing the same pair of denim jeans nearly for 15 months without washing does not pose any health risks.

In an effort to both learn how much bacteria was collected and create his ideal pair of jeans, a University of Alberta student wore a raw denim Nudie jeans 330 times without washing them from September 10, 2009 until December 17, 2010, reports ABC News.

Josh Le, a Canadian, got the idea to turn his denim into an experiment while attending an introductory to textiles class.

“My professor mentioned that she researches on textiles and bacteria, so it piqued my curiosity there. I half jokingly said we should do a bacterial analysis on them [Le''s jeans] and that''s where it sort of started,” he said.

Although he tried to keep them clean, the jeans sometimes had food
spilled on them and used paper towels to dab out the stains.

And whenever the jeans smelled too stinky, he used to stick them in the freezer overnight.

After 15 months and one week, Le asked his professor Rachel McQueen to test the jeans for bacteria before he washed them for the first time.

After washing, Le wore them for 13 more days, before retesting them again.

The results surprised Le and McQueen. They found that the bacteria count on the freshly washed jeans was similar to the levels found in the pre-washed sample.

“There did not appear to be differences in the bacterial carriage depending on whether the jeans had been worn for 15 months or only 13 days,” read McQueen''s findings.

She also said the bacteria present on the jeans came mostly from Le''s skin and was not harmful.

Le has now purchased another pair of jeans and is taking part in a challenge with a friend to see who can wear their jeans the longest.
