Researchers at Örebro University have found high levels of dioxins in food produced near a disused sawmill in Hillringsberg, Sweden, according to a study reported on March 5, 2026. The study analyzed meat from sheep grazing nearby, cow's milk, and both farmed and wild fish. All samples showed traces of pollution, with dioxin levels in a portion of sheep meat reportedly 11 times higher than what an adult should consume in a week and 26 times higher than a child's limit.
The sheep have been moved to new pastures, and a fish farming company relocated its operations despite no high levels being measured in farmed salmon. Small perch had higher levels than larger ones, likely due to more contact with contaminated sediment. The sawmill used pentachlorophenol, a toxic substance, over 50 years ago, but dioxins persist in the environment.
High dioxin intake can affect the immune system, fertility, and hormonal systems. Researchers call for similar investigations and relocations of agricultural activities in other Swedish municipalities.
