Effectiveness of two sanitation procedures for decreasing the microbial contamination levels (including Listeria monocytogenes) on food contact and non-food contact surfaces in a dessert-processing factory

► We try to find Listeria monocytogenes in a pastry factory and assess its survival after sanitizing. ► L. monocytogenes was not detected on food contact surfaces, but was found on the floor. ► Sanitization reduced the L. monocytogenes load, while not completely eradicating it.
