Quantitative analysis of survival of Staphylococcus aureus or Listeria innocua on two types of surfaces: Polypropylene and stainless steel in contact with three different dairy products

The survival of Listeria innocua and Staphylococcus aureus on two types of surface: polypropylene and stainless steel were investigated after contamination with milk products. Sheets were incubated at 12 °C or 25 °C during 8 days. The survival and growth of the two strains were possible but different according to milk origins, temperature and surface. L. innocua attached to stainless steel in cheese curd reached approximately 3.6 ± 0.2 Log CFU...
