‘Forever chemicals’ have made their way to farms. For now, levels in your food are low – but there’s no time to waste

"They stop your food from sticking to the pan. They prevent stains in clothes
and carpets. They help firefighting foam to extinguish fires. But the very
thing that makes “forever chemicals” so useful also makes them dangerous.

Forever chemicals – the catchier name for the class of chemicals known as PFAS,
per- and poly-fluoroalkyl substances – don’t break down in the environment.
Since we invented and began using them in the 1940s, these chemicals have stuck
around, contaminating water and soil. And when they make it into our bodies,
they can bind to proteins and accumulate in organs, which may increase your
cancer risk or damage your health. Major manufacturers are now facing lawsuits
over the potential health impact of the chemicals.

How do they make it into your body? There’s been a lot of concern over their
presence in drinking water. But there’s another risk – food. Like many
countries, Australia has long used biosolids as fertiliser. Made from processed
stormwater and sewage, this soil-like substance adds vital nutrients to our
notoriously poor soils.

The problem is, forever chemicals are now in biosolids. Even though the levels
are low, authorities are expected to soon make a precautionary change to
regulations which would prevent the use of biosolids, as we now understand
crops can accumulate these chemicals and pass them on to us.

Thankfully there are ways of making these chemicals harmless."
