Fecal Streptococci on Barley and Malt Kernels and Instant Malted Milk Powder ¹

Department of Biology, Rochester Institute of Technology, Rochester, New York 14623

ABSTRACT

Among 500 barley kernels, tested singly, 1.8% (9 kernels) were positive for fecal streptococci. Among 800 malt kernels, tested singly by the same procedure, 68% (540 kernels) were positive for fecal streptococci. In unsulfured and sulfured malts, 67 and 68% of the kernels, respectively, were positive for these bacteria. Fecal streptococci were also isolated by an enrichment procedure from two brands of instant malted milk powder sold in supermarkets. Seventy randomly picked isolates from malts were identified to be fecal streptococci, belonging probably to more than one species.

¹ Some of the results were reported at the spring meeting of the Central New York Branch of the American Society for Microbiology at Syracuse University, Syracuse, N.Y., on 7 April 1969.
