Screening of Salmonella in naturally contaminated feeds with rapid methods.
Five commercially available screening methods, the Oxoid MSRV, Merck SALMOSYST-RAMBACH AGAR combination, Organon Teknika SALMONELLA-TEKTM, Dynal DYNABEADS ANTI-SALMONELLA and Foss Electric EIAFOSS, were compared to the conventional culture procedure for the detection of Salmonella in naturally contaminated feed samples. A total of 217 feed samples from animal as well as from vegetable origin were examined. Twenty one samples were found to be positive for Salmonella by all methods combined. The conventional culture method detected 17 (81,0%), MSRV 19 (90,5%), SALMOSYST-RAMBACH 8 (38,1%), SALMONELLA-TEK 19 (90,5%), DYNABEADS ANTI-SALMONELLA 7 (33,3%) and EIAFOSS 21 (100%) of the 21 total Salmonella contaminated samples.
