A Comparison of Growth of Individual Meat Bacteria on the Lean and Fatty Tissue of Beef, Pork and Lamb

Abstract
Growth of Hafnia alvei, Serratia liquefaciens, Lactobacillus plantarum, Lactobacillus curvatus and Leuconostoc mesenteroides on inoculated lean and fat tissue of beef, pork and lamb was investigated. Increases in H. alvei, S. liquefaciens and L. plantarum counts on refrigerated beef and pork fat usually were greater (PL. mesenteroides and L. curvatus counts on fat were either smaller than or did not differ from those on lean samples. Sour, buttermilk‐like off‐odors were the most common defect on stored samples.
