A probe of the fungal infection of public hospital bed linen has identified lapses in almost every stage of the laundry process, according to an article on the South China Morning Post website.
The workshop was like a dusty and stuffy prison and the amount of fungus found in the samples was simply "frightening", a veteran microbiologist leading the probe, said in the article.
The panel detected fungus at the washing, drying and ironing stages, as none of the processes were carried out at the required high temperatures.
The bed sheets were packaged when they were still moist and warm, which could nurture fungus growth. Starch powder used in washing was stored next to rubbish bins.
