In the case of S. aureus, the results show that 60% of the raw milk samples contained < 102 cfu/ml and 30% contained between 102 and 103 cfu/ml. On only one occasion did a sample result exceed 104 cfu/ml. It is difficult to compare the results from this study with those conducted in other countries, because most studies express the results qualitatively, e.g. the prevalence of S. aureus in raw milk from studies conducted in other countries has ranged widely from 13 to 100% ( Adesiyun et al., 1998, Chye et al., 2004 and Jørgensen et al., 2005).
