Organic farmers are doing everything right — but that doesn’t stop glyphosate from blowing in.
When drift and legacy contamination strike, clean farming becomes a moving target.
When we picture organic farming, we imagine purity — fields free from chemicals, crops grown in harmony with nature, food we can trust. But for many organic growers across New Zealand and beyond, that picture is becoming harder to protect. Because even when they refuse to use synthetic herbicides like glyphosate, that doesn’t mean glyphosate refuses to visit them.
It drifts. It lingers. And it contaminates.
A Threat Blowing in the Wind
Spray drift is exactly what it sounds like — herbicide particles carried by wind, vapour, or even foot traffic from a sprayed paddock to a non-sprayed one. And with glyphosate-based products like Roundup used so widely across conventional farming, forestry, and even council parks, it doesn’t take much for residues to travel beyond their intended boundaries.
Glyphosate contamination can also come from legacy sources. Fields that were once conventionally farmed can continue leaching glyphosate and its primary metabolite, AMPA, years after the last spray. Residues persist in soil, wash into irrigation channels, and cling to dust particles. And when organic farmers lease land or share infrastructure, they may unknowingly inherit that invisible burden.
This isn’t just a rural inconvenience. It’s a systemic flaw — one that undermines trust, wrecks certifications, and leaves honest farmers picking up the pieces.
Contamination Without Consent
In 2023, Civil Eats reported on the growing concern among American organic farmers about glyphosate showing up in their produce — including wine grapes and oat milk. While that article has since disappeared from their site, the issue it raised has only grown more urgent.
Tests conducted by groups like the Environmental Health Network and the Real Organic Project have found glyphosate in certified organic products, raising uncomfortable questions: how did it get there, and who should be held responsible?
One farmer can spray — and another can lose their organic status.
Some shipments get rejected. Some crops get destroyed. Others quietly make their way to market, because glyphosate isn’t part of routine testing in most organic auditing processes — especially not here in New Zealand.
And the costs? They’re carried by the very people trying to farm responsibly.
Regulatory Blind Spots
Despite the known risks of spray drift and contamination, current regulations offer organic farmers little protection. In New Zealand, there are no mandatory buffer zones between glyphosate-sprayed areas and organic crops. There is no liability scheme for drift damage. And there is no national framework for consistent glyphosate residue testing on organic produce.
If a grower does test positive for glyphosate, they may face suspension of their certification — but it’s unlikely that the source will be investigated, let alone held accountable.
It’s a system tilted toward chemical convenience. And organic growers are the collateral damage.
Victims of Their Neighbours
One of the hardest truths for organic farmers to swallow is this: they can do everything right and still be penalized. Their crops, their reputations, and their livelihoods are vulnerable to someone else’s decisions.
They aren’t just fighting weeds — they’re fighting drift, runoff, and outdated laws that weren’t built for co-existence.
And when contamination occurs, it’s not Monsanto or Bayer that bears the consequences. It’s the grower next door who never sprayed a drop of Roundup.
Many organic farmers won’t speak out publicly — fearing loss of contracts, backlash from neighbors, or unwanted media attention. But the silence doesn’t mean the problem isn’t real. It means they’re trapped in a system where contamination feels inevitable and justice feels out of reach.
What Can Be Done?
We believe it doesn’t have to stay this way.
✅ Mandatory buffer zones between conventional and organic farms.
✅ Legal protections for growers harmed by glyphosate drift.
✅ Routine testing of organic produce for glyphosate contamination.
✅ Transparency from councils, contractors, and commercial operators about where, when, and how glyphosate is applied.
✅ Education and enforcement that prioritizes public health and ecological responsibility over chemical convenience.
And perhaps most importantly — a cultural shift. One that respects organic farming not as a niche lifestyle but as a vital part of New Zealand’s food future.
Final Thought
Contamination is not a matter of bad luck — it’s the predictable outcome of weak protections and stronger chemicals. And while farmers may be on the frontlines, it’s consumers, councils, and communities who must help draw the line. Because no one should lose their livelihood for choosing to farm without chemicals.
If we want a future where organic means what it says, we must protect it — not just in principle, but in practice.

These reports, articles, and books won’t give you all the answers — but they might help you ask better questions. Because real change starts with informed communities. And the more we know about what glyphosate leaves behind, the more we can decide what we’re willing to stand for — and what we’re no longer willing to accept.
