Detect 3 Salmonella targets in one test

POULTRY and pork producers can do a screen for three Salmonella targets with one rapid PCR test using the Thermo Scientific RapidFinder Salmonella Multiplex PCR System. This system is the first validated multiplex PCR assay for simultaneous detection of Salmonella species, Typhimurium and Enteritidis.

Thermo Fisher Scientific has been awarded AOAC-RI Performance Tested Methods^SM certification for the RapidFinder Salmonella Multiplex PCR Detection Workflow. Validated for use on the Applied Biosystems Food Safety 7500 Fast System and the Applied Biosystems Food Safety QuantStudio 5 System, the workflow features simple sample preparation and results in as few as 16 hours from raw and cooked poultry and pork as well as production environment samples.

"Salmonella serovars Typhimurium and Enteritidis are most commonly associated with the disease in humans. As a result there are multiple strategies and regulations targeting a reduction in the contamination level of these serovars in the poultry and pork industries," said Bernd Hofmann, vice president, global marketing, microbiology, Thermo Fisher Scientific. "Identifying the serovar of any Salmonella strain quickly can bring substantial economic benefits to pork and poultry producers. To be able to detect three targets in as few as 16 hours now means product may be released two or three days sooner than when using conventional tests."

According to the company, many rapid methods can detect all Salmonella species but not all provide the serovar identity of a Salmonella strain if detected. To get that information the laboratory must run additional rapid tests, which can prove very expensive, or use a series of conventional biochemical and serological tests that can take several days to complete.
