Can glyphosate herbicide residue in food cause non-Hodgkin lymphoma?
Growing evidence says yes. A 2025 review updated the evidence that glyphosate (Roundup) exposure is linked to non-Hodgkin lymphoma risk.
What's actually in it
Glyphosate is the active ingredient in Roundup, the world's most widely used herbicide. Residues remain on conventionally grown crops including wheat, oats, corn, and soy. These residues survive processing and end up in bread, cereal, and many packaged foods.
What the research says
A 2025 review in Clin Lymphoma Myeloma Leuk updated the evidence that glyphosate causes non-Hodgkin lymphoma. The authors found the accumulated evidence increasingly supports a causal link, consistent with IARC's classification of glyphosate as "probably carcinogenic to humans."
Choose organic produce when possible, especially for grains and oats. Wash all produce thoroughly. A water filter won't remove glyphosate from food but can reduce it in drinking water.
