Pestcides: what you need to know...

Updated: Apr 2

Exposure to pesticides is an increasing concern and we just don't know what the effects are of regularly consuming low doses of pesticide residue.


Studies have shown potential harm so I think reducing your exposure makes sense and may contribute to staying healthy.

Organic fruits and vegetables have been shown to have lower residues of pesticides than conventionally grown produce. However, sometimes it's not possible to buy organic so it's useful to know what produce you should try and avoid.

PAN UK (Pesticide Action Network) have complied a list of the best and worst offenders from the results of residue testing carried out by the Expert Committee on Pesticide Residues in Food (PRiF) from 2011-2015.

“Around 60% of fruit and vegetables contain pesticide residue”
