Among those adults, 73% displayed elevated intestinal inflammation, while 45% were infected with H. pylori, the bacteria that can cause ulcers and cancer.

Taken together, those results demonstrate widespread intestinal infections and inflammation at all ages in these low-income, mostly Black communities.

Long-lasting intestinal infections and associated inflammation can lead to nutritional deficiencies, restricted growth, reduced educational attainment, decreased work productivity and increased risk for serious diseases later in life, including certain cancers).

The Rural Embodiment and Community Health Study is not alone in recognizing the impact of intestinal infections on Black communities. One of the most widely publicized recent research studies investigating intestinal infections focused on the health effects of poverty and crumbling sanitation infrastructure in Lowndes County, Alabama, a region characterized by a history of racial segregation and inequity.

Researchers found that more than 1 in 3 people tested in Lowndes County were infected with hookworm, an intestinal worm spread through sewage exposure that lives in soil and infects people by burrowing into bare feet.

This 2017 study has since led to legal action.

In a landmark May 2023 court ruling, the Biden administration found that Alabama’s public health department had discriminated against Black residents by denying access to adequate sanitation systems and imposed fines for resulting sewage issues.

This decision is being hailed by environmental justice advocates as a transformative environmental justice agreement that may increase public awareness of the ongoing health crisis that results from infrastructure neglect and associated pathogen exposure.

Community activists – such as Catherine Coleman Flowers, founder of the Center for Rural Enterprise and Environmental Justice – said they hope the federal government continues to intervene, leading to similar results in other affected communities.

“This country’s neglect of wastewater infrastructure in majority Black communities, both urban and rural, is resulting in a hygienic hell for far too many people, a hell that climate change is only making worse,” Flowers said in a March 2023 interview.
