文摘

Staphylococcus aureus is an important human pathogenboth within the hospital setting and as a community-acquiredinfection. Recently there has been concern that landapplied biosolids may transmit S. aureus. However, noscientific data are available to document whether biosolidsare a source of S. aureus. To determine if S. aureus ispresent in biosolids, we collected samples from 15 sitesacross the United States. Samples analyzed were asfollows: 3 raw untreated sewage samples and 2 undigestedprimary sewage sludge samples; 23 different biosolidsamples; and 27 aerosols obtained during biosolid landapplication (biosolid aerosols). Although S. aureus weredetected in raw sewage samples, none were found in anyof the treated biosolids nor in any biosolid aerosolsamples. These results suggest that biosolids are not alikely source of S. aureus human exposure or infection.
