THE DISTRIBUTION OF SALMONELLAE IN PARALLEL SAMPLES OF A LOT

For three lots of commercially produced pasteurized spray-dried egg pr oducts that had been proved Salmonella-positive in a previous routine examination the Salmonella-distribution was determined using an MPN-te chnique (30 samples per lot). The Salmonella-count of most of the indi vidual samples did not exceed the detection limit of 0.03/g. In the sa mple units proved to be positive for salmonellae, the contamination le vel reached only low values with extremes of 0.93/g. Results indicate that for pulverized foods it is not necessary to assume that salmonell ae are concentrated in spots.
