Abstract
A method and apparatus for the automatic sampling for microorganisms in a liquid product flowing in a processing line. A stream of the product is directed away from the processing line and automatically injected in sequence into a plurality of microorganism collection devices. The stream is injected into each of the collection devices for a predetermined time interval. The collection devices contain sterile membranes which filter microorganisms out of the stream. Subsequent incubation of the membranes on nutrient media permits growth and detection of microorganism colonies. The detection of microorganism colonies in one of the collection devices permits the isolation of suspect liquid product bottled during the time interval when the collection device filtered microorganisms from the stream.
