Raman Spectroscopy Applied to Early Detection of Infection in Milk.

Detecting in milk presents a significant challenge for the dairy industry given that traditional methods are time-consuming and not specific for these bacteria. Microbiological techniques are expensive and require qualified personnel. , in the form of spores, can withstand pasteurization and revert to its vegetative form during cheese aging.

Phenotypic and Genotypic Characterization of Staphylococcus aureus Strains from Italian Dairy Products.

Staphylococcus aureus is a known major cause of foodborne illnesses, and milk and dairy products are often contaminated by enterotoxigenic strains of this bacterium. In the present study, 122 S. aureus isolates collected from different dairy products were characterised by phenotypic properties, by the distribution of genes encoding staphylococcal enterotoxins (sea, sec, sed, seg, seh, sei, sej, and sel) and by randomly amplified polymorphic DNA PCR (RAPD-PCR).
