Incidence of Coliform in Butter
Ikram-ul-Haq , Nuzhat Inam , Sikander Ali and M.A. Qadeer

Microbial examination of 50 samples of both packed and unpacked butter was carried out. The samples were examined for total viable count, mould and yeast count, spore formers and coliform. The microbial load in the unpacked sample of butter was highest i.e., 3.8 × 106/gm - 6.6 × 106/gm. The coliform count was found maximum in unpacked sample and one of the packed sample of butter (Kausar brand) i.e., 39/ml. The unpacked sample of butter contained highest number of aerobic spore formers i.e., 280/gm. The anaerobic spore-formers were found absent in 20 samples of butter and the rest contained in the range of 0-170/gm. The yeast cultures were found only in the sample of Lyallpur and Kausar butter. The mould count of these samples ranged from 0-280/gm.
