| 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 (P<0.05) than on comparable lean samples. On dark-firm-dry (DFD) beef, these differences in counts between lean and fat samples were smaller or disappeared. Increases in L. 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. |
