See also the post ‘A list of pesticides used in food production along with their associated risks‘
I created this for a project I’m working on. It shows the fresh foods available in UK supermarkets, when they’re in season, and their corresponding levels of residual pesticides. Sadly, simply washing food is not enough to remove pesticides as many of them are systemic meaning they enter the food through the skin. Use the following table to help you buy food in season and decide whether to aim for the organic version instead.

Ever wondered what’s really on (or even in) the fruit and veg you buy from the supermarket? Sadly it’s not just soil. Pesticides – chemicals used to kill pests – are now used on most of the food we buy from the average UK supermarket. They’re designed to kill living things, so it’s no surprise they can harm us too. As much as some people like to think we’re somehow separate to nature, we’re not. Something that is designed to kill insects will probably be harmful to us too. Studies link pesticide exposure to health issues like hormone disruption, fertility problems, and increased cancer risk. Scary? Yes. But don’t panic – a little knowledge and simple swaps will mean you can limit your expose to these chemicals.
No. This isn’t about perfection. It’s more about making smarter choices. As you can see from the table above, some foods contain a very high level of residual pesticides, but others are much less likely to have had harmful chemicals used on them. I would certainly recommend only eating the organic options when it comes to foods like strawberries or spinach, but other foods such as onions or pumpkin are much less likely to contain pesticides.
Many of the modern pesticides are systemic meaning they are inside the foods. The pesticide is absorbed by the plant and embedded within the leaves and fruit. no amount of washing can remove this type of contamination. These chemicals are designed to kill pests by disrupting their nervous systems or growth, so it’s not surprising that they can also affect human health. Here is a list of common systemic pesticides:
There are many reasons why seasonal foods are the better choice. Firstly they’re likely to be fresher and more nutrient rich. The UK seasonal foods are much more likely to have a lower environmental impact by being able to be grown locally, as opposed to many out-of-season foods which end up being shipped here from paces like Spain or even Africa. And you’re obviously more likely to be boosting your local economy too! But most importantly, in-season foods usually require fewer pesticides meaning they’re less likely to contain much less harmful chemicals.
I would suggest that firstly you sort the table based on the month you’re in. For example, if you’re food shopping in May, you can sort the table above to show the foods which are currently in season. You can then look at the corresponding likely levels of pesticides and choose what might be better to buy organic
