[Effect of temperature and storage time of industrial feed mixtures on the occurrence of presence of Staphylococcus aureus].
The purpose of this work was to determine the effect of temperature and storage time of industrial feed mixtures (IFM) on the occurrence of staphylococci. It has been found that freezing of experimentally infected IFM decreased initially the number of staphylococci. Further storage of IFM below 0 degrees C, even for 8 months, did not destroy completely these microorganisms. At 4 degrees C, the number of staphylococci decreased slowly. In IFM stored at 37 degrees C, or at room temperature, the number of staphylococci decreased rapidly. The storage of IFM at these temperatures may be a good method of removing infections of IFM caused by staphylococci.
