Coliform bacteria. Detection in foods and feeds. (NMKL 44, , 6.ed., 2004)
The method is applicable to all types of foods and feeds. However, foods and feeds containing other sugars than lactose, e.g. saccharose, may cause non-coliform bacteria to grow, with colonies resembling those of coliforms. Strains of e.g. Aeromonas, Flavobacterium and Erwinia, which sometimes occur in samples from sea water, raw fish, raw vegetables and grain, may grow on the plating medium to produce almost typical colonies.
