title: Microorganism-induced skin disease in workers exposed to metalworking fluids.
abstract: BACKGROUND
  An outbreak of skin disorders among workers potentially exposed to metalworking fluids prompted the present study. Few studies have described skin disorders associated with microbe-contaminated metalworking fluids.
  
  
  METHODS
  Samples of materials contaminated with metalworking fluids were obtained from two manufacturing facilities in Ohio. Pathogenic bacteria and yeasts, in concentrations sufficient to cause skin disease, were cultured from 9 of 12 (75%) sampled materials.
  
  
  RESULTS
  Allergic patch testing of five affected people produced negative results for standard allergens, augmented by fluids and items from their workplace. This ruled out allergies as the cause of the skin disease. Improper handling and disposal of cotton gloves, inappropriate use of scouring pads and ineffective hand wiping were apparently responsible for the microbiological contamination. The hands and forearms were most commonly affected.
  
  
  CONCLUSIONS
  Improper handling of soluble, synthetic and semi-synthetic metalworking fluids provides an excellent environment for the growth of a range of microorganisms, including bacteria and fungi. If allowed to grow because of poor occupational hygiene, these microorganisms can cause skin disorders among workers. Soiled protective clothing (gloves, coveralls and work boots) should be cleaned or discarded on a regular basis. When washing up, workers should not use metalworking fluids and items used to clean machinery.
