This Section of BS 4285 describes two methods of general application for the direct enumeration of bacteria:<\/p>\n

    \n
  1. method A: direct microscopic count technique for total counts in milk;<\/li>\n
  2. method B: direct epifluorescent filter technique (DEFT) for total counts or counts of bacteria in milk, certain milk products and samples such as rinses.<\/li>\n<\/ol>\n
    \n

    NOTE 1. In samples (including plant rinses) that have received some degree of heat treatment (equivalent to pasteurisation or greater), certain organisms, particularly Gram-positive cocci, will fluoresce orange (i.e. as active) but will be non-viable by plate count methods. Therefore great care is needed in interpreting results using such samples.<\/p>\n

    NOTE 2. The titles of the publications referred to in this standard are listed on page 5.<\/p>\n<\/blockquote>\n
