Carrot juice botulism outbreak - Live Blogging at ACI Conference

By Bill Marler, Esq.

I just finished my presentation here at the ACI Conference giving an overview of the increase in 2007 and 2008 in recalls and outbreaks associated with hamburger and E. coli O157:H7 when I got an email of an article from Clinical Infectious Diseases from its November 15, 2008 publication on the 2006 Carrot Juice Botulism Outbreak tied to Bolthouse Farms.

For those that do not recall, in September 2006, three people living in Georgia developed food-borne botulism that was eventually traced to commercial carrot juice from a single bottle. Soon thereafter an additional case in Florida and two in Ontario, Canada surfaced. One of the 6 botulism patients died 90 days after illness onset. One year later, two others were still on ventilators. The remaining three were taken off ventilator support after 54, 90, and 129 days. Two survivors were at home, two were in rehabilitation facilities, and one was still hospitalized. All the patients had consumed carrot juice from the same manufacturer.

Now, here is the interesting part, according to Dr. Anandi N. Sheth at the Centers for Disease Control in Atlanta, Georgia and colleagues, an investigation eventually determined that inadequate refrigeration probably led to botulinum toxin production. As the investigators pointed out, the pasteurized carrot juice had no protection against the bacterium Clostridium botulinum other than refrigeration. "This investigation demonstrates that carrot juice and other processed foods with no natural barriers to C. botulinum germination require additional chemical or thermal barriers," the investigators wrote in the medical journal Clinical Infectious Diseases. Accordingly, they report, "In June 2007, the FDA modified its guidance for refrigerated low-acid juices to recommend adding a validated juice-treatment method, such as acidification or appropriate thermal treatment, to decrease the risk of C. botulinum contamination, should any breaches in refrigeration occur."
