You may have heard of the "Clean Fifteen and Dirty Dozen", produced by the Environmental Working Group in the USA to list those fruits and vegetables that were found to have the lowest and highest levels of pesticide residues on them. But did you know that in the UK, the Pesticide Action Network (PAN UK) produces an annual "Dirty Dozen" list, informing us of the produce most likely to contain a cocktail of multiple residues. This is based on government testing in the previous year.
Shockingly, they found that a quarter of vegetables and THREE QUARTERS OF FRUIT tested contained multiple pesticide residues, including 42 chemicals linked to cancer.
PAN UK say "Safety limits are set for one pesticide at a time, completely ignoring the fact that it’s all too common for food to contain multiple chemicals. The truth is we know very little about how these chemicals interact with each other, or what this exposure to hundreds of different pesticides is doing to our health in the long-term. What we do know is that pesticides can become more toxic when combined, a phenomenon known as ‘the cocktail effect’."
Read the text in the infographics to understand why PAN UK doesn't produce a "Clean Fifteen" list and to see, based on limited data, the trends for the produce with pesticide cocktail residues over the past 5 years.
It's fair to say that we don't yet know the health impacts of all these chemicals, and we may never be able to show causation with disease, because how do you separate individual chemicals out from the cocktail effect? However, it's important to realise that allowing these chemicals in our food supply in untested combinations is a big experiment that we are being exposed to. I don't feel like chancing it, so buy as much organic as I can. However, it's not right that it is up to the individual to pay a premium in order to do this.
