New BAX® System Assay Helps Reduce Public Health Risk Associated with Campylobacter

DuPont Qualicon has released a new BAX® system assay for poultry rinses that detects both Campylobacter jejuni and Campylobacter coli, the strains most frequently implicated in human illness.

Traditional methods for detecting Campylobacter in meat and poultry are labor intensive, requiring about five days to determine results.   By contrast, the automated BAX® system can detect as few as 10 cells of Campylobacter in a 30 ml sample after just 24 hours enrichment.

“BAX® systems are already at work in labs around the globe, providing the best science-based tool for detecting microbial threats to the food supply,” said Kevin Huttman, president of DuPont Qualicon.   “As the international community strives to reduce Campylobacter all along the food chain, the BAX® system will be an integral part of the solution.”

Campylobacter are commonly found in the intestinal tracts of animals and some humans without causing symptoms of disease.   Infection occurs when people eat undercooked meat or poultry, raw milk or untreated water containing the live bacteria.  Consuming as few as 500 Campylobacter cells can cause illness.

A leading cause of gastroenteritis in many countries, Campylobacter are the most frequently isolated bacteria from persons with diarrhea.  An estimated 2.4 million cases of foodborne infection from these bacteria occur annually in the United States.  Although fatalities are rare, serious complications of Campylobacteriosis can include reactive arthritis and Guillan-Barré syndrome, an unusual type of paralysis.

Food processing companies around the world rely on the BAX® system to detect pathogens or other organisms in raw ingredients, finished products and environmental samples.   The automated system uses leading-edge technology, including polymerase chain reaction (PCR) assays, tableted reagents and optimized media, to detect Salmonella, Listeria monocytogenes, Listeria species, E. coli O157:H7 and Enterobacter sakazakii.  With certifications and regulatory approvals in the Americas, Asia and Europe, the BAX® system is recognized globally as the most advanced pathogen testing system available to food companies.

DuPont Qualicon also markets the patented RiboPrinter® system, the world’s only automated DNA fingerprinting instrument to track and trend bacterial contamination in pharmaceuticals, personal care products and food.  For more information and product photos, visit www.qualicon.com
