School Proximity to Concentrated
Animal Feeding Operations and Prevalence of Asthma in Students
American College of Chest Physicians
Released June 2006
The study examined two rural Iowa elementary
schools – one school ½ mile from a CAFO and the other
school distant from any CAFO. The results showed that children in
the school close to a CAFO had s “significantly increased
prevalence of physician-diagnosed asthma.”

Race, Poverty, and Potential Exposure
of Middle-School Students to Air Emissions from Confined Swine Feeding
Operations
Environmental Health Perspectives
Released April 2006
A North Carolina scientific study reports
factory farms are located closer to schools with higher populations
of low-income and minority children.
The study raises serious concerns about
the public-health problems children of lower socioeconomic status
might experience by being exposes at higher levels to factory farm
air pollution.
The study was published in the April 2006
Environmental Health Perspectives.

Iowa CAFO Air Quality Study
University of Iowa/Iowa State
University
Released February 2002
“The report, developed by the universities at the request
of Governor Vilsack, states that hydrogen sulfide and ammonia have
been measured near [CAFO] livestock operations in concentrations
that could be harmful to humans.”
–joint
press release from ISU and UI, Feb. 2002
The joint study stated, “By consensus
of the entire study group, the following substances should be considered
for regulatory action: 1.) hydrogen sulfide 2.) ammonia and 3.)
odors. The justification for regulatory action of these substances
is based on our assessment of the scientific literature, recommendations
by pertinent federal agencies, and review of regulations established
in other states.”
–page 6 of the study's Executive Summary
The joint University of Iowa/ Iowa State
University CAFO air quality study is a peer-reviewed, consensus
study from 27 scientists at our state universities.

Precautionary Moratorium on New
CAFOs
American Public Health Association
Released November 2003
In November 2003, the
American Public Health Association adopted a resolution urging federal,
state, and local government to impose a precautionary moratorium
on new CAFOs. One of the main reasons identified was serious respiratory
problems found among children, neighboring residents, and CAFO workers.

Asthma Prevalence and Morbidity
among rural Iowa School Children
University of Iowa - College of Public
Health
Released January 2004
University of Iowa study in Keokuk County
and Louisa County reported high rates of asthma and asthma symptoms,
comparable to rates found in large Midwesern cities.

Intensive Livestock Operations, Health, and Quality of Life among
Eastern North Carolina Residents
University of North Carolina
Released March 2000
In 2000 this North Carolina study reported
increased occurrences of headaches, runny nose, sore throat, excessive
coughing, diarrhea, and buring eyes from residents of large-scale
CAFO as compared to residents of the community with no intensive
livestock operations. Quality of life, as indicated by the number
of times residents could not open their windows of go outside even
in nice weather was greatly reduced among residents near the hog
operation compared to the control group.

Ambient Hydrogen Sulfide, Total Reduced Sulfur, and Hospital Visits
for Respiratory Diseases in Northeast Nebraska, 1998-2000
Agency for Toxic Substances and Disease
Registry (ATSDR)
Released March 2004
This is a peer-reviewed study from scientists
at the Agency for Toxic Substances and Disease Registry. The study
reports significant associations with hospital visits for asthma
following days of “high” levels (30 parts per billion
for 30 minutes) of exposure to total reduced sulfur, for children,
and hydrogen sulfide for adults among residents of Dakota City and
South Sioux City, Nebraska.
