Existing. People shed DNA all over. Most of the dust in your house is human skin and hair (or that of your pets). Non-sterile swabs are probably just packed with bare hands, by someone in their regular clothing.
Right, but there would be many people packing swabs in the plant. Unless she has psoriasis, the amount of skin she sheds at one time wouldn't contaminate all of the swabs she touched with her hands, much less all of the swabs in the factory.
Sweaty hands while sorting the cotton fibres would do it.
Not even close. Sweat barely contains any DNA, and while theoretically a person could sweat enough to leave behind enough dna to be identified, it hasn't ever happened and would require copious amounts of concentrated sweat. Her hands would have to be constantly dripping with sweat, and this happened several times in several countries between 2001 and 2008. Maybe sweaty hands could contaminate one or two cotton swabs, but all of them over the course of several years? No.
I did not realise sweat contained so little dna!
