The Trojan Chicken Study in Minnesota
Author Information

Primary Institution: University of Iowa College of Public Health
Hypothesis
What is the role of poultry exhibits at county fairs in spreading avian pathogens to humans?
Conclusion
The study found that 8.5% of poultry-exhibit participants had evidence of hand contamination, suggesting a risk of pathogen transmission at county fairs.
Supporting Evidence
- Eight participants (8.5%) had evidence of contamination.
- The study was conducted at two county fairs in the Midwest.
- Participants included members of 4-H clubs and their families.
Takeaway
At county fairs, some people touched chickens that might have germs, and a few of them ended up with those germs on their hands.
Methodology
Participants' hands were examined for contamination with a fluorescent powder used as a surrogate for avian pathogens.
Potential Biases
Participants were unaware of the contamination status, which may introduce bias in their behavior.
Limitations
The study's measure of contamination may not accurately reflect true pathogen transmission, and the sample size may limit the ability to detect differences by demographics.
Participant Demographics
Participants included poultry exhibitors, family members, and visitors, with a mean age of 33 years and a range from 7 to 79 years.
