Scientists at work using the BAX® System
Speed, accuracy and ease of use make the BAX® system a powerful part of quality control processes in the food industry.


The U.S. Food and Drug Administration (FDA) recently awarded test method equivalency to the BAX® System from DuPont Qualicon for detecting Salmonella enteritidis in eggs.

S. enteritidis, a foodborne pathogen most commonly associated with eggs, has been identified as the most frequent cause of Salmonella infection in Europe. In the United States, it’s responsible for 79,000 illnesses and 30 deaths each year. FDA regulations introduced in 2010 require egg producers to implement preventive measures and monitor for S. enteritidis with frequent testing.

“This FDA equivalence is welcome news for egg producers who prefer the BAX® System’s speed, accuracy and ease of use,” said Doris Engesser, global leader, DuPont Qualicon. “Significantly shorter enrichment with this method means that eggs can be released days faster, reducing inventory and refrigerated storage costs while helping to prevent contaminated products from reaching the food supply.”

Accuracy, precision and sensitivity of two BAX® System PCR assays – Salmonella and Salmonella 2 -- were determined equivalent to the reference culture method published in the FDA’s Bacteriological Analytical Manual. Results for both assays were available just 55 hours after sampling, instead of seven or more days required by the culture method.
