Health and safety advice of investigation team members Staff should wear rubber gloves when collecting and examining stool and urine specimens. Any material contaminated with excrement or urine should be soaked in sodium hypochlorite solution before reuse or disposal. 2.8. Quality Control Quality control is necessary to verify the consistency of the microscopic examination during the investigation, which is particularly important for Kato-Katz technology. Before the survey, one day should be spent evaluating the consistency of the egg count among laboratory technicians. A simple way
