Chris Jones, a research scientist who has warned about Iowa's worsening cancer trend, is running for the state's top agriculture job. His candidacy is drawing renewed attention to a claim linking public health and industrial pig farming.
The race is being framed around the allegation that Iowa's cancer rate is climbing faster than in any other state, with industrial pig farming cited as the likely reason.
Here's what to know
A post on Instagram from More Perfect Union (@perfectunion) presents Jones as a scientist already publicly associated with warnings about rising cancer rates and says he is seeking the Secretary of Agriculture job.
It connects his run for office to the warning about Iowa's cancer trend and points to industrial pig farming as the suspected source. While some suggest alcohol abuse or smoking cigarettes as a possible cause, one Iowa resident points out the obvious, saying: "But Iowa isn't the only state with binge drinking. Iowa isn't the only state that has smoking."
Advocates have highlighted elevated nitrate levels in drinking water, caused by pig manure used as fertilizer that runs off into the water system. Jones explains in the video that the Environmental Protection Agency established the "standard of 10" in 1974, the legal limit of 10 parts per million for nitrates in drinking water.
"Since that time, we've seen research that shows consuming water below 10, down to about 3 parts per million, is associated with these various cancers," Jones says. More Perfect Union's investigation tested rivers that were around 10 or even higher.

More background
By calling Jones the research scientist who "sounded the alarm," More Perfect Union casts his bid for office as a continuation of an existing warning, not an abrupt move into politics.
The concern extends to conditions around large-scale livestock operations and whether state institutions are equipped — or willing — to investigate connections between industrial agriculture and health outcomes.
In that context, the Secretary of Agriculture's office becomes part of the state's response to a serious health warning.
What's being done?
Jones' run for agriculture secretary is the main step the post describes. Instead of stopping at research and public alerts, he is pursuing an office that could affect Iowa's handling of industrial farming and related concerns.
A victory would place the scientist behind those warnings in state government, where he could shape priorities, oversight, and the seriousness with which those issues are examined.
The post centers on whether Iowa wants an agriculture secretary who treats cancer trends and pig-farm impacts as a central policy issue rather than a side debate separate from the farm economy.
More Perfect Union's post said: "Iowa cancer rates are growing faster than anywhere else in the nation, and industrial agriculture pig farming appears to be the culprit."

Similar disputes over agriculture and public health are playing out well beyond Iowa. These stories cover animal waste rules, contamination fears on farmland, free PFAS testing, farm chemical risks, and runoff damage.
• In Virginia, the governor approved animal waste regulations for farmers after fights over nitrogen discharges.
• Across the U.S., spreading sludge fertilizer on farmland has fueled fears over persistent PFAS contamination.
• In Connecticut, officials began offering free PFAS soil testing to farmers facing contamination worries.
• Scientists warned that a common crop fungicide may undermine human medicine and raise deaths.
• In the Gulf of Mexico, agricultural runoff fueled a vast dead zone fed by fertilizer.
