ABSTRACT
We evaluated the effect of temperature decrease of sanitation solutions (35 °C) in condition of organic load (1% reconstituted powdered milk) and varying hardness of the water used for solution preparation (0 °, 15 °, 30 ° and 45 °) on the ability to randomly selected strains of enterococci survive exposure to acidic and alkaline sanitation solution (0.5% concentration, contact time 15 minutes) in model experiments. Increasing water hardness also increases the number surviving enterococci. Presence of organic loads and lower temperatures decreased the sanitation effect of the test solutions. The tested strains showed different tolerances to applied sanitation solutions. We found a weaker powerful of acid sanitation solution on base phosphoric acid after its application.doi: 10.5219/166
