New environmental watchdog report: Pesticides found in everyday foods – "A serious concern"
Ever found yourself standing in the produce section, eyeing up a punnet of fresh strawberries or a bag of apples, and wondered what's really on the surface? Not just the dirt, but those invisible traces of pesticides nobody talks about at the barbecue. Last week, an internal memo from the Environmental Defence Society (EDS) landed on my desk and made me stop in my tracks. A colleague working on urban environmental issues had gotten wind of a new investigation into everyday groceries, and the results are frankly alarming. We're talking about substances that don't just affect the environment but also our health – and crucially, the bee colonies we're completely reliant on.
Bee-killing chemical cocktails in the fruit aisle
In the fresh report circulating internally at EDS, around 30 food items were analysed – everything from NZ-grown apples to imported grapes and pre-packaged smoothie mixes. Traces of at least one type of pesticide were found in nearly every second sample. But what really raised my eyebrows were the findings of neonicotinoids, a group of insecticides notorious for being lethal to bees. These substances have been banned within the EU for years, yet they're still turning up in goods from countries outside the bloc. And it only takes tiny amounts to disorient bees and wipe out entire colonies. As a former home gardener, it makes your stomach churn.
Everyday items where residues were found
- Fresh berries – imported strawberries and raspberries in particular contained several different pesticides.
- Stone fruit – peaches and nectarines from outside the EU topped the list.
- Leafy greens – salad mixes and spinach showed traces of fungicides suspected of being endocrine disruptors.
It's not the first time we've seen figures like this, but it's the first time in a while that EDS has pushed the issue so clearly in their own campaign. They point out that those of us in major cities often have a misleading picture that the food in our local supermarkets is cleaner than it actually is. On the contrary, the investigation shows it's more of a lottery – you never really know what you're bringing home.
Why you should care – even if you're not a beekeeper
It's easy to think, "I don't eat that many imported berries, it won't affect me." But these chemicals spread through the environment and impact all pollinators, which ultimately threatens our entire food production. Without bees and bumblebees, there are no apples, no cucumbers, no kiwifruit. Forest & Bird magazine ran an excellent piece a couple of years back about how our agricultural landscapes are becoming sterile due to chemicals leaching from things like imported fruit – through compost, wastewater, even our own clothing. It really puts things in perspective.
At the same time, it's easy to feel powerless as a consumer. Should you stop buying grapes altogether? One of the EDS experts I spoke with last week put it like this: "Choose local when you can, and most importantly – choose organic. Even if it costs a few dollars more, you're reducing the demand for these poisons." And it's true – every time we pick up a certified organic product, we're sending a signal all the way back to the grower.
What happens now?
The report has already gained traction in several councils around the country. In Auckland, there are now discussions about tougher guidelines for public catering – meaning the food served in early childhood centres and aged care facilities. EDS is pushing for a phase-out of all foods containing the most dangerous pesticides, even if they come from overseas. It's a tough ask given free trade rules, but someone's got to start the conversation.
Personally, I'll be rethinking my own shopping list from now on. And next time someone offers me a bag of cheap grapes from a far-off country, I might just politely decline and ask for a locally-grown carrot instead.
