DuPont’s Salmonella detection assay receives Performance Tested Method status

DuPont Nutrition & Health has announced that its new assay for detecting foodborne Salmonella with the DuPont BAX system has received Performance Tested Method status from the AOAC Research Institute.

The assay combines powerful polymerase chain reaction (PCR) technology with real-time detection to provide fast and accurate results.

DuPont Nutrition & Health global diagnostics leader Doris Engesser-Sudlow said that food companies that require certified testing methods can now use the Salmonella assay to help release products faster, saving inventory costs and extending shelf life.

The AOAC Research Institute is a non-profit, international, scientific organisation that implements the Performance Tested Methods programme, which offers an independent, third-party assessment of proprietary analytical methods to ensure that products perform as claimed.

Validation by the AOAC Research Institute found that the BAX System assay is an effective method for identifying Salmonella in raw ground beef, chicken rinses, cream cheese, bagged lettuce, dry pet food and on stainless-steel surfaces.

The BAX System is used by food processing companies worldwide to detect pathogens and other organisms in raw ingredients, finished products and environmental samples.

The automated system employs technology such as PCR assays, tableted reagents and optimised media to detect Salmonella, Listeria species, Listeria monocytogenes, E. coli O157:H7 and STEC, Staphylococcus aureus, Campylobacter, Vibrio, and yeast and mold.

DuPont noted that the BAX System has certifications and approvals from government agencies in the Americas, Asia and Europe.

DuPont Nutrition & Health, a business of US-based chemical company DuPont, offers bio-based ingredients and microbial diagnostic solutions to provide safer, healthier and more nutritious food.
