Abstract: In this study, hygienical microbiology was examined from strawberry according to the food hygiene standard of People Republic of China, with bacteria isolated from strawberry fast identified by Vitek Auto Microbic System. The results showed that the levels of strawberry microorganisms including bateria, molds and yeasts, exceeded the food hygienical microbiology standard. Therefore, fresh fruits should not be eaten directly. The experiment isolated 16 bacteria species(14 G- and 2 G+), so they could be classified into 10 genuses, 8 families by Berger’s manual of determinative bacteriology. Most of identified microorganisms could cause diseases. The experimental results are helpful to control the number of microorganisms and develop new technology to sterilize for strawberry.
