Some Iowa State University students are changing their plans for studying in Europe this summer due to the outbreak of “Mad Cow” and “Hoof and Mouth” disease. Trevor Nelson of the I-S-U study abroad program says students have taken notice of the turmoil in the U-K. Nelson says the greatest concern among students is confusion over the impact of each disease. “Mad Cow” can impact humans, “Hoof and Mouth” disease does not. Nelson says students from the Ag and Veterinary Medicine Colleges did have trips scheduled to farms in England and Ireland, but they’ve since cancelled the visits to the farms to prevent any possibility of spreading “Hoof and Mouth” disease. Nelson says the trip won’t be a total loss.He says the trip now presents and opportunity for ISU students to study how the countries are responding to the disease outbreak.Nelson says approximately 500 students will take some type of trip to study abroad this summer. Iowa’s Governor said Monday he’s urging federal officials to impose stricter rules for European travelers to keep “Hoof and Mouth” disease off our continent.
