Abstract
Environmental monitoring for microorganisms concerned with quantitative detection of the contamination on surfaces are not often carried out in the same way, because it is unknow how much to press against a surface with forceps . In this study, we evaluated the recovery of microorganisms with the swab method, using newly developed Torque Forceps with different levels of force. The recovery from a force of 150g/cm2 was relatively low. However, forces of 300g/cm2 and 450g/cm2 yielded almost the same results.
