Eating contaminated food is still far and away the most common way for people to become infected with E. coli O157:H7, a deadly pathogen that sickens more than 70,000 Americans each year (see also PritzkerOlsen Attorneys).
But national food safety law firm PritzkerOlsen Attorneys is reminding families early in 2009 that contact with animals at livestock shows, petting zoos and other exhibits is another proven way for the organism to travel.
The law firm's warning stems from a current E. coli O157:H7 outbreak in Colorado. Health officials there are investigating an apparent connection between a growing number of genetically matched infections and attendance at the recent Western National Stock Show in Denver.
According to numerous press reports, at least 20 people who live on the Front Range in Colorado have been infected with the same strain of E. coli. Sixteen of the illnesses are in children who attended the animal exhibit, including a child who is 17 months old. The two-week show drew more than 643,000 attendees before it ended January 25 and health officials expect the number of E. coli O157:H7 infections in the current outbreak to grow.
"This outbreak should not have happened and could have been prevented," said Fred Pritzker, founder and president of PritzkerOlsen. "When stock shows encourage or permit public contact with animals, there is a well known risk of E. coli O157:H7 infection and equally well known measures that should be in place to prevent such infections."
Pritzker said the Centers for Disease Control and Prevention (CDC) and the National Association of State Public Health Veterinarians, Inc. (NASPHV) published a compendium of such infection prevention measures almost four years ago.
"Although the matter is still under investigation, it seems likely that rules of this sort were not implemented or followed," he said. Escherichia coli O157:H7 is a rare variety of E. coli that produces a toxin that causes severe damage to the lining of the intestine. Specifically, the acute disease caused by E. coli O157:H7 is hemorrhagic colitis. E. coli O157:H7 can also result in hemolytic uremic syndrome (HUS), the leading cause of kidney failure in children in the United States.Preventive Medicine Week
