In the laboratory the samples were examined by the methylene blue test, colony count, coliform and Escherichia coli I test and for pathogens. Staphylococcus aureus was grown from 59 out of 3417 samples of cream; 54 of these were from untreated cream. Phage typing indicated that a proportion of these strains were of animal, presumably bovine, origin. Other human pathogens isolated included one each of Sa...Continue Reading
