BAX® System for Detecting Salmonella Adopted as AOAC Official Method

The BAX® system, a genetics-based pathogen screening method developed by DuPont Nutrition & Health, has received AOAC® Official Methods status for Salmonella.

AOAC International is a worldwide provider and facilitator in the development, use and harmonization of validated analytical methods. AOAC Official Methods are cited in the U.S. code of federal regulations and adopted by standards organizations around the world. The Official Methods program (OMA) provides for multi-laboratory validation of a method where the highest degree of confidence in performance is required to generate credible, defensible and reproducible results.

The BAX® system for detecting Salmonella was successfully validated and has been assigned AOAC Official Methods number 2003.09.

'The BAX® system continues to be adopted as the standard for accuracy in foodborne pathogen testing around the world,' said Kevin Huttman, president of DuPont Nutrition & Health. 'AOAC Official Methods status adds to the many government approvals that already recognize BAX® system accuracy - a key value to our global customers.'

'By using the BAX® system as an integral part of their food safety programs, global companies are able to safeguard the world's food supply and their brand names. The BAX® system allows any quality assurance laboratory to work with a sophisticated technology that transforms the most advanced molecular biology concepts into the simplest, fastest food analysis method available,' he emphasized.

Salmonella are foodborne pathogens that can cause salmonellosis, a severe intestinal illness in humans. Infection is more common in summer than winter, and contamination can often be traced to raw or undercooked meat, poultry, eggs and dairy products. Thorough cooking will kill the bacteria, but cross contamination can occur through food handling errors, such as unwashed hands or contaminated utensils. The Centers for Disease Control estimate that 40,000 cases of salmonellosis are reported annually in the United States, although the actual number of infections may be 30 times that since milder cases are often not reported. Approximately 600 people die each year from acute salmonellosis, and about 2 percent develop Reiter's syndrome, which can lead to chronic arthritis.

The BAX® system detects target bacteria in raw ingredients, finished food products and environmental samples. The automated system, which takes little space and looks like a desktop computer, has been available since November of 2000. Hundreds of BAX® systems are already in use by governments, food companies and laboratories in 30 countries.

DuPont Nutrition & Health provides the most advanced molecular technologies for pathogen screening. In addition to the BAX® system, DuPont Nutrition & Health markets the patented RiboPrinter® system, the world's only automated DNA fingerprinting instrument that rapidly pinpoints sources of bacteria in pharmaceuticals, personal care products and food.
