Four fresh and two frozen samples of the krill (Euphasia superba) were examined bacteriologically. Coryneform like organisms were predominent in the bacterial flora of fresh krill along with strains of Pseudomonas , Moraxella‐like taxa, Alcaligenes , and Flavobacterium . Bacterial counts were low and ranged from 650/g‐1,100/g at 25°C. Studies of the spoilage flora developing during cold storage show that, similar to other fishery products, bacteria of the Pseudomonas, Alcaligenes and Moraxella ‐like taxa groups predominate. The bacterial count was low, 9,800/g at 25°C, on krill processed and stored at ‐20°C for 45 days. Enzymatic evaluation showed that krill bacteria have strong proteolytic and lipolytic activity.
