In response to a fourth case of botulism, Bolthouse Farms of Bakersfield, Calif., recently recalled its 100 percent carrot juice with the "best if used by" dates of Nov. 11 or earlier from shelves in the United States, Mexico, Canada and Hong Kong.

"While the labels on our 100-percent carrot juice products indicate its perishable nature and need for refrigeration, and while recalling the product is an extreme measure, the company felt it most appropriate to pull our 100 percent carrot juice products off the market in the interest of consumer safety," Bolthouse said in a statement. "If you have the product in your possession, please destroy it or return it to the store at which you purchased it for a refund."

The fourth case of botulism poisoning involves an adult female in Florida who is currently suffering from paralysis, according to the Food and Drug Administration. To date, one link between the illness and the consumers appears to be that the juice they drank was not properly refrigerated once they took it home, which allowed the Clostridium botulinum spores to grow and produce toxin. The FDA is investigating other possible links.

"All Bolthouse Farms processing facilities have been examined closely by internal auditors and the FDA and have been found to be in compliance will all appropriate controlling regulations," Botlhouse said in a statement. "In addition, samples from suspect lots have been examined by the FDA, and all samples have been found to be toxin free. These results clearly indicate a likely link between consumer temperature abuse and the development of botulinum toxin."
