Meat and Fresh Produce Companies Can Now Get Accurate Pathogen Results Within One Day

BAX® System Test for E. coli O157:H7 Certified as AOAC Performance Tested Method

DuPont Qualicon is pleased to announce certification for its recently released BAX® System test for E. coli O157:H7 in food.  The AOAC Research Institute has validated this real-time PCR assay, developed in collaboration with the USDA Agricultural Research Service, as a Performance Tested MethodSM for detecting the pathogen in spinach, lettuce, raw ground beef and beef trim with same-day results.

The AOAC Research Institute, a subsidiary of AOAC International in Gaithersberg, Md., provides rigorous evaluation and review of analytical methods before awarding its widely recognized Performance Tested MethodSM certification mark.

Fast, accurate results are critical when testing perishable products for pathogens,” said Luiz Fischmann, global marketing manager -- DuPont Qualicon. “This assay was developed to detect all known E. coli O157:H7, even atypical strains, within hours instead of days. Now meat and produce processors that require a certified method for quality control can benefit from BAX® System speed, accuracy and ease of use.”

E. coli O157:H7 are foodborne pathogens that live in the gut of cattle and other ruminant animals. These bacteria produce Shiga toxin, which can cause serious illness when ingested, even in very low doses. Although thorough cooking destroys the pathogen, the U.S. Centers for Disease Control estimates about 70,000 people are infected each year from consuming E. coli O157:H7.

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 species, Listeria monocytogenes, E. coli O157:H7, Enterobacter sakazakii, Campylobacter, Staphylococcus aureus, Vibrio, and yeast and mold. With certifications and regulatory approvals in the Americas, Asia and Europe, the BAX® system is recognized globally as one of the most advanced pathogen testing system available to food companies.
