Abstract

Two trials were conducted to compare the standard culture procedure and the ReportTMSalmonella Visual Immunoassay for detection of salmonellae in rinse fluid recovered from raw poultry carcasses. Both assays were evaluated with and without preenrichment in lactose broth prior to enrichment in selenite cystine broth. Live birds were inoculated via the drinking water prior to processing to ensure a high degree of carcass contamination. Prechill carcasses were sampled using 200 mL of sterile water. Results indicated that lactose preenrichment was not necessary for salmonellae evaluation using standard culture procedures. However, the ReportTM assay produced fewer false-negative results if lactose preenrichment was utilized.
