Why WHO Is Re-Examining Pesticide Residue Safety Calculations
The World Health Organization has called for experts to re-examine how pesticide residue exposure is calculated — a quiet signal that current safety models may not fully reflect real-world diets.
Why “Within Limits” Isn’t the End of the Glyphosate Conversation
When glyphosate residues are found in food, the reassurance is often the same: the levels are “within regulatory limits.” But that phrase doesn’t tell the whole story.
The Flowers We Don’t Question: An Overlooked Pesticide Exposure Risk
Flowers are rarely questioned as a source of chemical exposure. But unlike food, cut flowers sit outside pesticide residue limits — creating a regulatory blind spot with real implications for workers’ health.
Presence vs Amount: What Testing Can (and Can’t) Tell Us
When we talk about glyphosate testing, most people assume it means measuring exact amounts. But environmental testing often starts with a simpler question: is it present at all? This explainer unpacks what screening tests can — and can’t — tell us, and why presence matters before dose.
Glyphosate, Playgrounds, and the Illusion of Safety. Why Would New Zealand Be Any Different?
After glyphosate residues were found in UK playgrounds, questions are being asked about children’s exposure. With routine spraying across New Zealand, why would our playgrounds be any different?
When “Best Practice” Isn’t in the Contract
Whangārei District Council reviewed its use of glyphosate following public concern and a roadside spraying complaint. While safety improvements were recommended, many were not written into contracts. This article examines what changed, what didn’t, and why regulatory assumptions matter when spraying occurs in public spaces.
When “No Food Safety Risk” Still Means a Trade Risk
How can a food be considered safe to eat, yet still raise trade and reputational concerns? Using glyphosate in honey as an example, this article explores what “safe” really means.
MPI Honey Testing vs Independent Testing — What the Numbers Tell Us
MPI testing has found glyphosate residues in New Zealand honey before. Our independent testing asks a different question: how common are those residues when you look closely at retail products?
Digital Labels and Cheap Imports: What New Zealand Needs to Know
MPI’s digital labelling trial promises lower prices — but by reducing the cost of importing food rather than supporting New Zealand growers. This article explains how digital labels weaken transparency, encourage offshore sourcing, and risk long-term impacts on local producers, food sovereignty, and consumer choice.
The Online Shopping Blind Spot: What MPI Overlooked in Its Digital Labelling Trial
Online grocery shoppers can’t see product labels until food arrives — and that makes MPI’s digital labelling trial especially risky. This article explains why removing information from physical labels could undermine safety, allergens, substitutions, and traceability for New Zealand households.
