Description
Plate Count Agar is equivalent to the medium recommended by the APHA1and the PHLS 2 for the plate count of micro-organisms in food, milk and other dairy products.
The APHA method consists of the preparation of pour plates using diluted samples, and counting colonies after incubation. Incubation is for 48 hours at 32°C or at 35°C for the Standard Plate Count. For the enumeration of micro-organisms with other temperature requirements, plates may also be incubated for 7-10 days at 5-7°C: for 3-5 days at 20°C; for 2-3 days at 45°C; or for 48 hours at 55°C. See the APHA1 publication for details.
