Abstract: The chicken’s fermented excrement has been widely used as the reused feed or the manure, the detection of its pathogens is especially important, so the research on the detection of E.coli and Salmonella in fresh excrement and fermented excrement was carried. The results showed that the CFU of E.coli decreased from 3.67×107/g to 6.33×105/g after fermentation and no Salmonella in fermented samples were detected. The difference was very significant (P<0.01) as compared with the samples before fermentation, this showed the detection was feasible.

Key words: chicken’s excrement; fermentation; E.coli; Salmonella; detection
