How many cases of foodborne disease are there in the United States?
An estimated 76 million cases of foodborne disease occur each year in the United States. The great majority of these cases are mild and cause symptoms for only a day or two. Some cases are more serious, and CDC estimates that there are 325,000 hospitalizations and 5,000 deaths related to foodborne diseases each year. The most severe cases tend to occur in the very old, the very young, those who have an illness already that reduces their immune system function, and in healthy people exposed to a very high dose of an organism.

A study which investigated germs collected on footwear, by Dr. Charles Gerba, microbiologist and professor at the University of Arizona, and The Rockport® Company, found large numbers of bacteria both on the bottom and inside of shoes; averaging 421,000 units of bacteria on the outside of the shoe and 2,887 on the inside. Some of the bacteria found on the shoes included: Escherichia coli, known to cause intestinal and urinary tract infections, meningitis and diarrheal disease; Klebsiella pneumonia, a common source for wound and bloodstream infections as well as pneumonia; and Serratia ficaria, a rare cause of infections in the respiratory tract and wounds.
The goal of the study was to verify bacteria levels on footwear and the effectiveness of machine washable shoes in reducing those levels inside and outside the shoe surface. The project also investigated the role of shoes in the movement of bacteria from contaminated floor spaces to other surfaces.
