Walloon Farmers Destroy Crops Over Cadmium Contamination
Vegetable farmers in Belgium’s Wallonia region are being forced to destroy their harvests due to dangerous levels of cadmium contamination in the soil — a crisis with roots in both historical industrial pollution and modern agricultural practices. An investigation by RTBF has revealed that at least 12 market gardeners have been affected, with approximately 48,000 hectares of agricultural land — roughly 7% of Wallonia’s usable farmland — potentially too contaminated for safe cultivation.
The Scope of the Problem
In 2025, Belgium’s Federal Agency for the Safety of the Food Chain (AFSCA) conducted targeted testing of 48 vegetable producers — 30 in Wallonia and 18 in Flanders. Of the 12 samples that exceeded European cadmium limits, 11 came from Walloon soil, representing a non-compliance rate of 25% in the targeted zones, as Tchak reported.
Affected farmers include Frédéric Bronne and Jérôme Debruxelles, organic farmers in Olne who were forced to destroy their kale crop in 2021, and Adrien Libois in Andenne, who had to destroy his potatoes and onions in 2025. An unnamed farmer in Chièvres was also compelled to destroy a spinach crop.
“It’s a catastrophe,” Bronne told RTBF. “You question everything. Is what we’re growing still safe? Did we make a mistake?” Libois expressed similar shock: “We’re a bit stunned to learn that our plots are polluted without us knowing. We don’t work to poison people — that’s not our goal.”
Historical and Modern Sources
The contamination has two primary sources. Historically, Wallonia’s Sambre-Meuse valley was a center of heavy industry, with non-ferrous metal smelting around Liège, the Vesdre valley, and the Pays de Herve leaving lasting deposits of cadmium, lead, and zinc in the soil. Walloon Environment Minister Yves Coppieters confirmed in a May 2026 parliamentary address that “the main historical source of soil contamination by cadmium is the fallout of dust produced by the non-ferrous metal industry.”
However, the problem extends beyond historical pollution. As the minister noted, phosphate fertilizers now represent “the main source of cadmium input on agricultural soils.” Belgium’s primary supplier of phosphate fertilizers is Morocco, whose sedimentary phosphate rock naturally contains higher cadmium levels than igneous sources from Russia or South Africa, according to L’Avenir.
Health Implications
Cadmium is classified as a Group 1 carcinogen by the International Agency for Research on Cancer. It accumulates in the body over time, increasing the risk of chronic diseases including cancer, kidney damage, and bone disorders. According to the Scientific Institute of Public Service (ISSeP), nine out of ten Walloons are contaminated with cadmium, and nearly 5% have excessive levels. A 2023 ISSeP study found that 95% of Walloon children tested had cadmium in their urine, with levels three times higher than a 2011 national sample.
No Compensation for Farmers
Despite the devastating impact on livelihoods, no financial support exists for farmers forced to destroy their crops. Minister Coppieters’ cabinet stated bluntly: “No compensation mechanism is currently planned.” The government cites the “polluter pays” principle as a legal obstacle, noting that the historical industrial polluters are long defunct.
Agricultural unions have reacted with fury. The FUGEA farmers’ union demanded urgent action, stating: “No farmer has to this day been officially warned by the authorities” about contamination on their land. The union argues that farmers cannot be held responsible for pollution they did not create, whether from natural soil composition or historical industrial activity.
Regulatory Landscape and Future Outlook
European Regulation 2019/1009, which took effect in July 2022, sets a limit of 60 mg of cadmium per kilogram for CE-marked phosphate fertilizers. France adopted stricter limits in June 2026 — aiming for 40 mg/kg initially and 20 mg/kg eventually. Belgium, however, has not conducted a study on cadmium content in fertilizers since 2014.
The European Commission is expected to release a report on July 16, 2026, which could pave the way for stricter EU-wide limits. Federal Agriculture Minister David Clarinval indicated he is awaiting this report before taking a position.
For the affected farmers, the wait is agonizing. As Frédéric Bronne told RTBF: “The farmer is not responsible for past soil pollution.” With no compensation in sight and thousands of hectares potentially unfit for vegetable cultivation, Wallonia’s agricultural sector faces an uncertain future — one where the legacy of industrial history and the chemistry of imported fertilizers have converged into a crisis that leaves growers holding the bill.
