title: Meticillin-resistant Staphylococcus aureus (MRSA) environmental contamination in a radiology department.
abstract: OBJECTIVE
  To explore the potential risk to patients and healthcare workers of acquiring meticillin-resistant Staphylococcus aureus (MRSA) in clinical and non-clinical areas within a radiology department.
  
  
  METHODS
  High-risk sites in clinical and non-clinical areas within the Department of Radiology were identified and 125 environmental swabs were obtained by an infection control nurse specialist. Decontamination methods and protocols were reviewed and compared against international decontamination best practice.
  
  
  RESULTS
  One of 125 samples was culture positive for MRSA. The positive sample was isolated from the surface of the bore of the magnetic resonance imaging (MRI) unit. A hypochlorite cleaning agent was applied using a long-handled brush to clean the bore of the MRI unit. A repeat environmental screen found the MRI unit to be culture negative for MRSA.
  
  
  CONCLUSIONS
  This study has demonstrated that standard decontamination measures are adequate to prevent environmental contamination with MRSA in a radiology department. However, the MRI unit requires special attention because of its long bore and difficult access.
