<p>A method of determining the presence of microorganisms on a surface comprises contacting the surface to be tested for the presence of microorganisms with an adhesive side of a sheet consisting essentially of a porous, flexible support material having an adhesive surface on at least one side such that when contacted with a microorganism-containing surface, the microorganisms will be adhered thereto; removing the sheet from this surface; placing the sheet on a sterile culture medium for microorganisms, the side placed on the medium being that opposite the side which was in contact with the test surface; incubating the sheet; and analyzing the incubated sheet for the presence of microorganisms. A sheet for use in the method comprises a porous, flexible support material having an adhesive surface on at least one side and which is sterile throughout, said adhesive surface being such that when contacted with a microorganism-containing surface, the microorganisms will be adhered thereto.</p> |
