March 20, 2006 (Press Release) --
Petting zoos may be fun for the kids, but they are breeding grounds for bacteria that can cause severe gastrointestinal illness, new research contends.
Most people aren't aware that simple prevention measures such as handwashing could prevent infection, and some do things that might increase their risk, according to three new studies being presented Monday at the International Conference on Emerging Infectious Diseases meeting, in Atlanta.
Bacterial infection can result from touching anything that has come into contact with animal feces, including the animals themselves and surfaces that people have touched after petting the animals, eating or drinking while petting or feeding the animals, the researchers noted.
In addition, feces carried away on shoes can be taken home and become a risk for infection.
The first study deals with outbreaks of E. coli O157:H7 at two Florida petting zoos a year ago that sickened at least 34 people. The researchers, from the U.S. Centers for Disease Control and Prevention and the Florida Department of Health, interviewed visitors who did and did not get sick, to find out which behaviors predicted infection.
The behaviors most strongly associated with illness were feeding a cow or goat, touching a goat and stepping in manure or having manure on your shoes. Indirect contact that also led to illness included drying hands on clothes after washing them at the zoo.
Those who washed their hands after visiting the petting zoo, including lathering with soap and washing them again before eating, escaped illness, the researchers report.
In the second study, a team led by Amy E. Belflower, an epidemiologist at the South Carolina Department of Health and Environmental Control, watched 227 people in a petting zoo to see how many washed their hands or engaged in risky behaviors.
The petting zoos followed the guidelines, Belflower said. "They had the animals in pens, had signs about not bringing food and drink in, and lots of signs about washing your hands, and had good handwashing stations," she said.
"But even with all those precautions, we still saw people engaging in risky behavior," Belflower added. "The top three were bringing food into the area, bringing a stroller into the area, picking stuff like pet food off the ground. We also saw that 28 percent of the people who exited the petting area did not wash their hands."
In the third study, researchers from the Tennessee Department of Health and the U.S. Department of Agriculture also looked at how people behave in petting zoos.
