But the FDA, meanwhile, is battling food contamination closer to home. Robert’s American Gourmet (Sea Cliff, N.Y.) is recalling the snack food Veggie Booty after the FDA linked the snack to salmonellosis outbreaks in 17 states. So far, 51 people have been infected, mostly children.

Symptoms of salmonella poisoning include fever, nausea, diarrhea, and abdominal pain. The infection is especially troublesome among children, the aged, and those with weakened immune systems, who have been known to die from the effects of salmonella.

Although Robert’s American Gourmet is still saying that the link between the salmonellosis and the snack food is unproven and circumstantial, an FDA source states unequivocally that “an ongoing investigation has identified Veggie Booty as the source of a multi-state outbreak of salmonellosis.”

The ongoing investigation began in March.

In a major health crisis, the BBC is reporting that Irish city Galway has been struck by a cryptosporidium outbreak.

Cryptosporidium is a protozoan that can cause severe vomiting, diarrhea, and stomach cramps in humans (cryptosporodiosis). What’s worse, infestation by this intestinal parasite can be fatal to children, the elderly, and those with compromised immune systems, such as AIDS patients.

Galway is not the first city to be struck by such a crisis, nor is it likely to be the last. Cryptosporidium spreads by use of an oocyst phase that is not affected by chlorine or most other common disinfectants. Once this water-borne parasite invades a water supply, it is likely to cause illness in up to 50% of the citizens drinking the affected water.

A major outbreak of cryptosporidium in Milwaukee, Wisconsin in 1993 killed more than 100 people out of an estimated 880,000 served by the affected water treatment facility. The plant was shut down, but during the two week period that it remained open, 403,000 residents became ill. This was the worst waterborne disease outbreak documented in the United States.

Ozonation and treatment with ultraviolet light have been shown to be effective treatments for disabling the protozoan, but filtration and boiling are the most commonly used methods to achieve water safety.

Unlike many parasites, cryptosporidium passes its entire life cycle in a single host, so an infected host will excrete oocysts in its feces. If those oocysts can reach a water supply, the cycle continues.

Some recent reports indicated that the Galway outbreak occurred through leakage from a sewage treatment plant. However, others have reported that the waste causing contamination was animal as well as human, indicating that agricultural runoff could be involved as well.
