Performance of the Millipore SPC Sampler was compared with the Standard Plate count method for routine checks of bacterial counts in cannery cooling waters. Methods were tested with cooling waters from a hydrostatic retort. Recovery of viable bacteria was very low when the Millipore samples were incubated for 24 h, but incubation for 48 or 72 h consistently yielded higher counts with the Millipore than with the standard method. Duplication of counts between analysts was approximately equal with both methods. Replication of bacterial counts within samples was more erratic and skips were more frequent with the Millipore than with the standard method. Procedures to control replications and skips are discussed. The Millipore procedure is a convenient alternative to the Standard Plate Count for routine quality audit of cannery cooling waters. |
