At the time there are various options in the range of disinfecting materials applied in animal husbandry. In animal husbandry and food processing industry a new type of biocide – neutral anolyte (ANK) has been used for the purposes of disinfection, presterilization, purification and sterilization. ANK is produced in the STEL devices by electrochemical activation of sodium chloride solution. Aim of the study: to evaluate (under the laboratory conditions) the antibacterial washing qualities of neutral anolyte ANK, produced in the STEL-10N-120-01 devices, in its application for washing and disinfecting milking equipment and parlours. The efficiency of disinfection was estimated applying the method of pads (LAST EN ISO 4833: 2003). Inhabitable materials in the water were identified using “Delves” test, according to the standard LST 1263:1999. The physical-chemical examinations of water were carried (HN 24:2003). Under the laboratory conditions, anolyte ANK (produced in the STEL-10N-120-01 devices) solution with the concentration of 0.05% suppressed the increase of the Escherichia coli, Staphylococcus aureus, Streptococcus agalactiae, Salmonella and the coliform bacteria. The anolyte ANK solutions with the concentration 0.05% and 0.025% (made from the 0.05% solution watering it down in proportion 1:1) were not efficient in the pig farm A. The 0.05% anolyte ANK solution was efficient sanitarily treating the milkers equipment in the farming B.
