Dioxins
Dioxins and similar compounds, such as dioxin-like polychlorinated biphenyls (PCBs), include a range of toxic substances which are formed by burning – e.g. through waste incineration or forest fires – and some industrial processes. Their presence in the environment has declined since the 1970s, following concerted efforts at the EU level.
Dioxins are found at low levels in many foods. They do not cause immediate health problems, but long-term exposure to high levels of dioxins has been shown to cause a range of effects, including cancer. Their persistence and the fact that they accumulate in the food chain, notably in animal fat, therefore continues to cause some safety concerns.
