title: [A new rapid automated photometric method in analysis of quantitative indicators of food product contamination].
abstract: Thirty-five specimens of pasteurized milk were tested for bacterial contamination by rapid autocalibration photometry for liquid, semiliquid, and homogenized hard foodstuffs, developed by the Ecotest Firm, Russia. Photometric (turbidimetric) analysis was carried out using the Labsystems (Finland) iEMS Reader plate photometer and Russian Analitika BACT software. The results of traditional analysis and the new rapid method developed by Ecotest were in good correlation, the differences did not surpass the magnitude of errors of measurements. The new method takes just 10-15 h instead of the routine 72 h and requires 300 times less nutrient media.
