Last week consumers of organic produce got their knickers all in a knot over news reports of pesticide residue being found on “organic” produce. Now, I thought that we all knew by now that purchasing organic produce didn’t guarantee avoidance of pesticides. Apparently not.
Just a reminder… Organic food is not grown in isolation. There are pesticides in the soil, the rain, the air. Organic foods are not shipped and sold in isolation. There are many stages at which they may become contaminated with pesticides. Indeed, organic foods may also have pesticides deliberately applied during the growing process. Pesticides are allowable in organic farming, provided that they are not synthetic. For a list of permitted substances in organic farming see this from the Government of Canada.
Before we all give-up on organic produce, it’s worth considering a couple of things. One, it appears that the number of samples was quite small (the image at the bottom of the CBC article shows a sample size of 30 for the grapes). This could mean that the numbers are not an accurate reflection of the state of pesticide residue in produce in Canada. Two, only 1.8% of organic samples exceeded allowable limits for pesticides; 4.7% of non-organic samples did. In fact, less than half of the samples of organic produce tested positive for pesticides at all. While 78.4% of non-organic produce tested positive. Considering the numerous opportunities for organic produce to becomes contaminated with pesticides the number showing residue is actually quite small.
Yes, you’re taking a risk that your food is going to be contaminated with pesticides. That risk is present whether you choose organic or not. However, that risk is considerably greater if you choose non-organic produce. It’s also worth taking into consideration that by choosing organic produce you’re choosing to have fewer synthetic pesticides put into the environment. Over time, this may mean that your organic food will be less and less likely to be contaminated with synthetic pesticides.
