[Bacteriological and hygienic control of rendering plants (author's transl)].
Procedures for the hygienic inspection of animal rendering plants should include the bacteriological investigation of the meat meal, the bacteriological control of the used methods of disinfection of the contaminated rooms, of the transport vehicles and of the sewage of the contaminated side. Meat meal has to be free of Clostridium perfringens and Salmonellae. Clostridium perfringens is an indicator of the sterilizing effect of the rendering procedures. After an effective disinfection of rooms no gramnegative and only a small numbers of grampositive bacteria like aerobic bacilli should be demonstrable. Sewage of the contaminated side has to be free of Clostridium perfringens spores.
