You’re not likely to see a picture of Campylobacter in a post office lobby, but as of July 2011, the FSIS has introduced a new performance standard to reduce the prevalence of Campylobacter, similar to the one used for Salmonella for years.

Like the FBI, the FSIS has a “most wanted” list and wants to use it to protect families and communities. However, the FSIS will accomplish this goal by targeting Campylobacter in young chickens and turkeys at processing plants.
President Obama’s Food Safety Working Group developed three core principles to help guide food safety in the United States: prioritizing prevention, strengthening surveillance and enforcement, and improving response and recovery. The group’s overall mission is to ensure a safe food supply for the public. The new standards are a way to encourage businesses that slaughter young chickens and turkeys to focus on reducing the number of foodborne pathogens to make the food supply safer.
When Salmonella and Campylobacter show up in the food supply, the whole industry suffers. The illnesses they cause add to the cost of production, invite more regulatory scrutiny, and, more often than not, damage brand reputation. With the growth of social media, bad news in the food industry travels fast.
A 2011 report from the CDC estimates that approximately 845,000 illnesses are caused by Campylobacter each year.1 The FSIS projects that it will be able to prevent 5,000 illnesses each year through enforcement of the new Campylobacter standards.2 What makes this even more important is the fact that the most vulnerable consumers are those with weakened immune systems, including children and the elderly.
Researchers at the University of Florida Emerging Pathogens Institute recently determined that the five leading bugs, with Campylobacter at the top of the list, result in economic losses of $12.7 billion annually.3 Such reports spurred the FSIS to develop its stricter performance standards for young chickens and turkeys being prepared for market.
According to the FDA: “Surveys have shown that C. jejuni is the leading cause of bacterial diarrheal illness in the United States. It causes more disease than Shigella spp. and Salmonella spp. combined,” and poultry has been identified as the main source of infection.4 Recent improvements in animal husbandry and carcass processing methods have made progress, but it is doubtful Campylobacter will be eliminated any time soon. Further reduction does seem to be an attainable goal, however.
Just as FSIS performance standards are changing, so too are testing methods. Enumeration testing is increasingly favored over presence/absence testing. Brilliance CampyCount Agar from Thermo Fisher Scientific makes that an easy transition.
Just as FSIS performance standards are changing, so too are testing methods. Enumeration testing is increasingly favored over presence/absence testing with the availability of new alternatives to traditional culture media and most probable number methods.
Brilliance CampyCount Agar is a novel, selective, chromogenic medium for the enumeration of Campylobacter jejuni and Campylobacter coli in poultry and related samples. It is a welcome alternative to traditional culture media and most probable number (MPN) methods.
This novel medium was recently certified during an independent MicroVal ISO 16140 study as equivalent in performance to Campylobacter blood-free selective agar base (CCDA) at enumerating C. jejuni and C. coli from poultry samples.5 A separate independent study conducted in Canada demonstrated that Brilliance CampyCount Agar was superior to traditional and competitor chromogenic media at recovering C. jejuni from spiked poultry samples and comparable in performance to traditional media (CCDA and Campy-Cefex Agar) for enumerating C. coli.6
Brilliance CampyCount Agar is designed for accurate, specific, and easy enumeration of C. jejuni and C. coli. It is a transparent medium, and positive colonies are colored dark red, making identification significantly easier than on conventional charcoal or blood-containing agars. Counting is simple because the transparent medium allows enumeration on plate readers. When used in conjunction with O.B.I.S. campy or the Oxoid Dryspot latex agglutination test from Thermo Fisher Scientific, a confirmed result can be achieved in as little as 48 hours.
As recently as 2009, Campylobacter incidences were underreported, even though food safety is a top priority for the USDA. Underreporting is not likely to happen now that it’s on the FSIS “most wanted” list.
