Abstract: E. coli, the bacteriological indicator of fecal- borne contamination in foods, is accepted as indicator bacteria in health testing all over the world.To detect the contamination levels of coliform /E.coli in three common shellfishes on Qingdao market, 3M PetrifilmTMtest was performed.The correlation between coliform, E.coli and local temperature was demonstrated by spearman rank correlation coefficient.Spearman rank correlation coefficient was0.481, 0.712 respectively, which showed the positive correlation between coliform / E. coli in bivalve and the local temperature.This study suggested that the storage, transport and quality control of shellfish should be given great attention when the local temperature was high.
