TL;DR: Observations show that the dicing machine sustained the contamination and suggest that theDicing machine transferred the persistent L. monocytogenes PFGE type from one plant to another, which caused persistent contamination of the d slicing lines in plants B and C.

TL;DR: In compartments that produced cooked meals, the cleaning routines, product types, and lack of compartmentalization seemed to predispose production lines to persistent contamination, so special attention should be paid to continuous quality control of raw ingredients when uncooked ready-to-eat foods are produced.

TL;DR: Overall, automated ribotyping can be considered a practical and rapid tool when Listeria contamination is suspected and when screening a large number of isolates is necessary, e.g., when tracing contamination sources.

TL;DR: In this paper, the authors evaluated nine disinfectants and a hypochlorite-based disinfecting cleaning agent against eight Listeria monocytogenes strains representing three different ribotypes and found that the most efficient agent was isopropanol-based and the least effective was the disinfectant containing tertiary alkylamine and dimethyl alamine betaine.
