Separation Identification and Analysis of Salmonella in Animal Feedstuff

With the routine culture separation and identification technique, the salmonella was separated, identified and analyzed from 69 copies of formula feed, 77 copies of concentrated feed, 44 copies of fishmeal and 39 copies of meatbone meal that was gathered from some feed factory and plant. As a result, 27 strains of salmonell were separated at the rate of 11.8%(27/229). And they were from 7 copies of formula feed, 6 copies of concentrated feed, 8 copies of fishmeal and 6 copies of meatbone meal which at a positive rate of 10.1%(7/69), 7.8%(6/77), 182% (8/44)and 15.4%(6/39).
