In Hog Farm Country, Communities Became Co-researchers

Colleagues remember Steve Wing as a different kind of scientist — one who believed advocacy and participation should be at the heart of scientific research.

“Community participation was central to the approach [Wing] believed in,” says Phil Brown, a member of the National Advisory Environmental Health Sciences Council. “[He believed] community residents were usually the most reliable discoverers of problems.” Wing was an associate professor of epidemiology at the University of North Carolina at Chapel Hill until he died in November 2016. As a public health researcher, he advocated the use of community-based participatory research (CBPR) and sought to involve communities threatened by environmental hazards in every step of the research process. Brown says that Wing’s dedication to CBPR serves as an example to other researchers who see their advocacy and research as intertwined.

For 20 years, Wing worked with the people living near large farming operations in North Carolina’s hog country. With more than 2,100 hog farms, North Carolina is one of the largest pork-producing states in the country. Farms are concentrated in the eastern portion of the state, where most divert pig waste to open-air lagoons. When hurricanes hit, the lagoons overflow, spilling untreated hog waste into rivers, lakes, and backyards. When they’re working as intended, the lagoons contain the waste in deep pits that turn pinkish-purple from bacteria, emit toxic gases, and seep into groundwater.

Hog manure is poisonous stuff, but prior to Wing’s studies in the area, not much research had been done on the impacts of pig waste on human health. “People living around animal operations were seeing changes in their well water and smelling odors,” says Naeema Muhammad, co-director of the North Carolina Environmental Justice Network (NCEJN). Locals felt their concerns were ignored by area officials with ties to industry, says Muhammad. So they approached Wing to design a study on the health impacts of the farms.

To help build trust, community members were treated as co-researchers. That research partnership produced studies that found pollution from large hog operations was associated with increased blood pressure, respiratory symptoms, and stress. Another study found Black, American Indian, and Hispanic North Carolinians were more likely than White residents to live within 3 miles of an industrial hog farm.

Collaboration didn’t end once the study results were published. Wing brought the data back to the community. “People became more aware [of the health risks],” says Muhammad. “This was information that could help them.”

In a 2015 interview for North Carolina Health News, Wing explained why he believed collaborative research is important: “The research questions we choose and the studies we conduct respond to the needs of government or industry — basically, the organizations that have money to spend on research,” he said. “I became interested in the idea that there are problems that wouldn’t be identified by the authorities, that we could learn about if we just listen to the people who are exposed.”
