Not a Happy Campylobacter

Posted on October 23, 2011 by Shawn Stevens

There has been a lot of attention drawn to recent salmonella and listeria outbreaks, and, in turn, those pathogens themselves. In the meantime, the pathogen Campylobacter has worked itself into relative obscurity. This may seem surprising, as CDC estimates that Campylobacter associated illnesses affect as many as 845,000 Americans each year.

Campylobacter is a spiral-shaped bacteria that causes disease (Campylobacteriosis) in both humans and animals and is often found in the intestinal tracts of poultry, cattle, swine, domestic animals, and sometimes humans. The bacteria pass through feces and can also be found in untreated water. It is the leading cause of diarrheal illness in the United States (USDA).

Symptoms of infection due to the bacteria usually occur 2 to 5 days after consuming contaminated food, however, it may take as long as 10 days for symptoms to appear. This is similar to E. coli and the two are often confused for one another. The most common symptom is diarrhea which can often times be bloody. Other symptoms include fever, nausea, abdominal pain, headache, vomiting, and muscle pain. Like most FBIs, those most susceptible to contracting Campylobacteriosis are young children, elderly persons, and pregnant women.

In most instances, campylobacter infections resolve without serious illness occurring. It is important to note, however that even though complications from Campylobacter infections are rare, they can occur. The following are the most common:

  • Gullian-Barre´ Syndrome (GBS): most common cause of generalized paralysis. GBS occurs when antibodies built up to fight the disease attack nerve cells.
  • Reactive Arthritis: inflammation of the joints, eyes, reproductive or urinary organs.
  • Appendicitis

In the event that a widespread outbreak was to occur, even statistically insignificant numbers of individuals affected by such complications could spell disaster for a company. The resulting lawsuits could easily result in millions of dollars in settlements and significant brand damage.

As with preventing all foodborne illnesses, maintaining sanitary conditions and remaining cognizant of potential hazards can make all the difference in preventing Campylobacter outbreaks. With continued awareness of harmful bacteria such as Campylobacter, and how we can prevent it from occurring in our food, we can continue to prevent serious foodborne illnesses from affecting our families and ourselves.

USDA Sets New Pathogen Standards For Poultry

Posted on May 15, 2010 by Shawn Stevens

Agriculture Secretary Tom Vilsack has announced that the USDA will be issuing new performance standards designed to reduce the prevalence of Salmonella and Campylobacter in poultry.

According to Vilsack, this will be the first time the standards for chicken have been revised since 1996, and the first time the turkey standard have been revised since originally set in 2005.

In particular, the new performance standards will set the maximum positive rate for Salmonella in raw chicken carcasses at 7.5 percent, which represents a significant decrease from the current stanndard of 20 percent . The new performance standard for Campylobacter would allow roughly 46 percent of raw carcasses to test positive.

According to National Chicken Council spokesman Richard Lobb, a USDA baseline study from data collected from July 2007 to June 2008 showed an industry-wide 8.1 percent positive rate for Salmonella and a 40 percent positive rate for Campylobacter. For 2009, he said that the positive rate for Salmonella actually decreased to 7.1 percent. For this reason, Lobb explained that "the new standards are generally consistent with industry performance in recent years." In turn, Vilsack has indicated that the USDA hopes to have the new standards in place between July 1 and August 1, 2010.

In addition to unveiling the new performance standards, the USDA also announced that FSIS has developed the third edition of its compliance guide for poultry slaughter. Click on the following link to view the revised FSIS Compliance Guide.

The new guidance materials include additional and revised pre-harvest recommendations designed to assist processors in their continuing efforts to reduce these pathogens to the greatest extent possible.

Food-borne Illness Vaccine May Become A Reality

Posted on September 2, 2009 by Shawn Stevens

The battle for food safety continues to be waged on multiple fronts.

In addition to testing and developing new technologies (beyond cooking) to reduce naturally occurring pathogens in food, researchers are now looking for ways to defeat pathogens in our bodies.

As we reported previously, continuing NASA research might soon lead to a Salmonella vaccine. And now, we have learned, the United States military has joined the fight. According to the Washington Post, a new scientific breakthrough recently announced by the Naval Medical Research Center suggests that a Campylobacter vaccine may be on the way as well.

Campylobacter is well known as a leading cause of food-borne illness. According to some studies, the pathogen may be responsible for as many as two million cases in the United States each year, and cause several hundred million more worldwide. The infection can also (in some instances) be difficult to treat because of widespread antibiotic resistance.

Nevertheless, after a quarter century of research, Navy scientist Patricia Guerry may have discovered the path to a vaccine which will inhibit the bacteria’s ability to attach to our intestinal lining and cause illness. Indeed, as explained by the Washington Post:

Guerry, a molecular microbiologist, began her work in the 1980s and over time created new research tools that allowed her to identify the pathogen's unique genetic, biochemical and structural features. This led to the development of a vaccine that neutralizes the bacteria's ability to attach to the intestinal lining.

The vaccine candidate against the pathogen Campylobacter jejuni, developed by Guerry, her colleagues at the U.S. Naval Medical Research Center in Silver Spring and Canadian scientist Mario Monteiro, successfully protected against infection in monkeys during testing last year and is slated for human clinical trials.

If true, this may be the first known (and, promising) food-borne illness vaccine actively tested on humans. And, although Guerry has been conducting her research as part of an ongoing effort to better protect U.S. soldiers oversees, her research, of course, may very well have a profound impact on the rest of the nation – and world.

In any event, this is great news for industry and consumers alike. We proudly salute Guerry and, of course, the rest of her team.
