Assessing microbial contamination of a flat material, e.g. food packaging, comprises moving a microorganism-collecting device relative to the material to strip microorganisms from it

摘要

Assessing microbial contamination of a flat material, comprising moving a microorganism-collecting device relative to the material to strip microorganisms from the material and examining the device for microbial contamination, is new. An Independent claim is also included for a device for assessing microbial contamination of a flat material, comprising a microorganism-collecting device that can be moved to strip the material, and can be examined for microbial contamination.
