FDA Cautions Food Firms to Insist on Confirmatory Test for Salmonella Analysis

In a revised document, the Food and Drug Administration (FDA) stresses caution when testing for Salmonella in human foods and direct-human-contact animal foods. Their guidance instructs firms to insist on an extra confirmatory test after receiving a positive screen result for the presence of Salmonella. Moreover, the analysis should be conducted according to the cultural method measures advised in the FDA’s Bacteriological Analytical Manual (BAM) or a validated non-BAM method.
 
The new document, Guidance for Industry: Testing for Salmonella Species in Human Foods and Direct-Human-Contact Animal Foods, explains that cultural methods can provide one of three results: a presumptive positive, a confirmed positive, or a negative result. The guidance remarks that firms should consider any confirmed positive to be valid.
 
“Some testing laboratories report a positive result for Salmonella without confirmation—only to find out later that the pathogen was not actually there, but an organism that resembles it,” states Joy Dell’Aringa, M.S., RM (NRM), CFSP, National Food Microbiology Supervisor at EMSL. “Without the culture-based confirmatory tests, there is no way to say definitively that Salmonella is present or not.”
 
“EMSL Analytical always offers post-screening confirmatory tests for presumptive positive samples using validated methods, so our clients can be assured of our results’ accuracy,” she continued.
