[Attempt to evaluation of the microbiological purity of dish table subjected to mechanical washing process].

The aim of this work was attempt to assess the microbiological purity of dish table subjected to mechanical cleaning process. The total number of microorganism and the total number of yeast and mould on the surface of flat and deep plates and cups was marked in this experiment. These marks were made immediately after dishwashing process. Residue of dirtying mixture on the surface washed plates were observed. Despite of organic residual remaining after dish washing process, they were characterized by low total number of microorganism (<1 cfu/cm2) and slightly higher (1.94 cfu/cm2 for flat plate and 0.85 cfu/cm2 for deep plate) total number of yeast and mould. In the case of cups, there was no residue of dirtying mixture and number of marked microorganism groups were at a very low level (total number of microorganism--0.04 cfu/cm2, total number of yeast and mould--0.06 cfu/cm2).
