We independently tested four widely sold Marlborough Sauvignon Blancs for glyphosate and related herbicides. Here’s what the lab results showed — and what “not detected” really means.
Six popular oat products were tested in New Zealand and none showed detectable glyphosate above 0.010 mg/kg. A reassuring result — for these specific batches.
Our fourth round of honey testing shows glyphosate residues in four out of five retail honeys. Levels ranged from a non-detect in Hunt & Gather’s Kānuka honey to the highest result we’ve recorded so far — Wrights Mānuka (Kerikeri) at 146.7 ppb, exceeding New Zealand’s legal limit for honey.
We commissioned independent, accredited lab tests on five popular supermarket breads in September 2025. Three loaves tested clean at trace levels, while two contained measurable glyphosate residues. See the full results and why they matter.
Our third round of honey testing reveals glyphosate residues remain common in New Zealand honey. Six out of seven samples contained detectable traces, and one exceeded the domestic Maximum Residue Limit.
We tested six popular supermarket breads for glyphosate and related chemicals. No residues were found above the reporting limit, but that doesn’t mean they’re glyphosate-free.
We tested seven mānuka honeys from NZ supermarkets and online retailers. Glyphosate was found in five — including some of the country’s most trusted brands.
Our independent test of four Weet-Bix varieties found one with detectable glyphosate. It’s not a name-and-shame—it's a community-led baseline for safer food.
