Abstract
A study was made to determine the extent to which coagulase-positive, potentially enterotoxigenic staphylococci could grow in milk held under refrigeration. These organisms were enumerated using a modified Tellurite-glycine agar medium. Coagulase-positive staphylococci were recovered from all raw milk samples examined, initial counts ranging from 25[long dash] 3300 per ml. They did not multiply in naturally Infected milk held at 4[degree]C for 7 days. Multiplication varied up to 1000-fold when the milk was held at 10[degree]C for 7 days. The greatest count obtained was 360,000/ml. At both storage temperatures the standard plate count increased much more than the Staphylococcus count.
