ABSTRACT:
A microbial sampling, filtration, and recovery device which utilizes a wash solution on meat carcasses and a vacuum source to vacuum the wash solution and suspended microbes into a collection device. The collection device includes pre-filters for removing debris, and a microbial filter. The filter is small enough to filter out bacteria, and since this size of filter seriously reduces air flow, an alternate route for air is provided through a hydrophobic filter. Bacteria captured on the filter is back-flushed into a collection vessel where it is concentrated in a subsequent centrifuge step. The concentrated microbial sample is available for use in rapid detection methods.
