A note on the isolation of Staphylococcus aureus from raw minced meat.

Conventional Baird-Parker medium (BP) and three modified BP-type media were tested for their suitability to detect and to enumerate Staphylococcus aureus in raw minced meat. BP with pig plasma gave the most rapid results without the need for extensive confirmatory tests. A method which combined a liquid modification of BP medium with BP agar supplemented with acriflavine, polymyxin and sulphamezathine, was cheaper, more sensitive, and did not necessitate additional identification. Conventional BP incubated at 37 degrees and 43 degrees C yielded less satisfactory results.
