The problem
Why is PFAS in your backyard a problem?
Since 2025, the Dutch public health institute RIVM has advised people in many parts of the Netherlands to stop eating eggs from backyard chickens. Meanwhile, new permits for discharging PFAS are still being issued. How is that possible?
Read the explanationWhy is PFAS 'niet pluis' (not right)?
PFAS is not right because these 'forever chemicals' barely break down, accumulate in people and nature, and so harm our health and that of the generations after us.
Why can't I eat my backyard chickens' eggs anymore?
The Dutch public health institute RIVM advises against eating eggs from backyard chickens, because they can contain a lot of PFAS. You cannot see or taste how much PFAS is in them. Eggs from the shop are fine to eat.
What is PFAS?
PFAS are thousands of man-made chemicals that barely break down. They have spread across the whole world and are now found in nature and in our bodies. Too much PFAS can make you ill. Not all long-term effects are known yet.
How does PFAS get into my backyard?
In many ways. PFAS spreads through water, air and soil, and can end up in your backyard too.
