Ireland Has 60 Vegetable Growers Left with Kenneth Keavey #189

Kenneth Keavey has a PhD in chemistry and spent his early career in pharma and biotech. He now grows organic vegetables on twenty-five acres outside Galway, and he's the first to point out the irony: he was an organic chemist, and now he's an organic farmer.

In this episode he takes Laura through what's actually on the food we eat, and how little of it we're told. Around 95% of conventional fruit and veg has had some treatment or another. Citrus is dipped or sprayed after harvest in waxes containing quite toxic, in some cases carcinogenic, chemicals to stop fungus growing on the skin. Most of it is legal, disclosed somewhere, and almost never read.

Then comes the detail that stops the conversation. In the EU you're allowed 10mg of glyphosate per kilogram of wheat and 20mg per kilogram of oats — twice as much of a probable carcinogen in your porridge as in your toast. Kenneth and Darina Allen went to the Department of Agriculture to ask why. They were told that people eat less porridge than they do toast.

It isn't all alarm. Kenneth refuses to scaremonger and is as clear about what isn't known as what is. He's also quietly hopeful: his own land is full of insects and birdsong, and he has watched how fast nature comes back when you let it.

🔑 Key Points

He was an organic chemist before he was an organic farmer

His PhD is in chemistry and his first career was in pharma and biotech, which is where the caution comes from.

Around 95% of conventional fruit and veg has had some treatment

Post-harvest waxes on citrus contain toxic and in some cases carcinogenic chemicals, and some produce carries up to fifteen applications.

You're allowed twice as much glyphosate in porridge as in bread

The EU limit is 10mg per kilogram of wheat and 20mg per kilogram of oats. Kenneth and Darina Allen asked the Department of Agriculture why, and were told people eat less porridge than they do toast.

The safety data usually comes from the manufacturers
