[Agents and methods for the disinfection of the integument of animals before slaughter].
Experiments were carried out to test the disinfection effect of some agents, such as chloramine B, chloramine B+ surface active substances, vofasteril (peracetic acid), perfumaric acid, and bradofen on a dry skin or when applied immediately after washing--in buffaloes, cattle, and swine. Parallel trials were conducted under conditions of the practice as well. Escherichia coli and Staphylococcus aureus were used as model organisms. Results showed that best disinfection effect have 1.5 percent chloramine B and 0.5 per cent peracetic acid (for dry skins), and 3.0 and 0.8 per cent of the same agents when applied on wet skins (immediately after washing). The animals should be slaughtered not earlier than 10 min and not later than 30 min following disinfection. The effect of disinfection is read best on impression preparations of agar (in aluminum folio).
