摘要
Eighty-three samples of raw milk were assayed by the Standard Plate Count method with incubation periods of two and three days. The three-day incubation period gave higher counts (0.05 > p > 0.01). There were no appreciable problems (such as drying-out, spreaders, molds, etc.) encountered when plates were incubated the extra day. An optional three-day incubation period for the Standard Plate Count is recommended.
