Abstract
A survey on the bacteriological quality of ground beef in Maryland was conducted to provide information relating to establishment of bacterial standards on fresh meats. One hundred forty samples were obtained at the retail, processor, and slaughter-processor levels. Retail samples yielded the highest bacterial numbers. The mean coliform, fecal coliform, and Escherichia coli count per gram, for all samples, was 200, 10, and 5, respectively. The mean total aerobic plate count per gram was 7.9 × 106 (28 C) and 2.0 × 106 (35 C). Forty-three percent of all the samples analyzed exceeded 50 fecal coliform per gram, while 18% exceeded a total aerobic plate count of 1.0 × 107 per gram.
