Abstract: | A rapid 18–24 h immunofluorescence technique detected 14 of 15 positive samples in tests on 706 routine samples, which included 656 home produced raw beef samples. The rapid technique also recorded 49 false positive results, i.e. samples which proved negative in subsequent cultural tests. The immunofluorescence technique could be used as a presumptive screening test aimed at the rapid detection of negative samples. In this way salmonella free raw materials should usually be cleared for production within 1 day of sampling. |
