What it means
A large number of students at schools near hog facilities reported difficulty breathing. Wheezing and asthma affect the ability of students to attend school and take part in social and physical activities. The treatment of asthma can be costly. Hog facilities are more often located in low income and African-American communities where children already have more asthma.
This research highlights the possible harmful health effects of industrial hog facilities by showing a link between exposure to hog facility pollution and wheezing in students.
