This study analyzed data from the CHAMACOS (Center for the Health Assessment of Mothers and Children of Salinas) longitudinal birth cohort to investigate the relationship between urinary glyphosate and AMPA (aminomethylphosphonic acid, glyphosate's primary metabolite) levels and markers of liver inflammation in young adults.
Researchers found that participants with higher urinary concentrations of glyphosate and AMPA had significantly elevated biomarkers of liver inflammation, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and markers of non-alcoholic fatty liver disease (NAFLD). The CHAMACOS cohort consists predominantly of Latino families in California's Salinas Valley agricultural region.
This is one of the first human studies to directly link glyphosate biomarker levels to organ-specific damage, providing crucial evidence that glyphosate exposure at levels found in agricultural communities contributes to liver disease.
Key Findings
- •Urinary glyphosate and AMPA levels were positively associated with elevated liver enzymes ALT and AST, biomarkers of hepatocellular damage.
- •Higher glyphosate exposure correlated with increased risk of non-alcoholic fatty liver disease markers.
- •The associations were significant after adjusting for BMI, alcohol consumption, and other liver disease risk factors.
- •Young adults ages 18-20 already showed signs of liver inflammation correlated with their glyphosate exposure.
- •Agricultural community residents had higher glyphosate levels than the general population.
Methodology
Prospective cohort study using the CHAMACOS birth cohort in Salinas Valley, California. Urinary glyphosate and AMPA were measured using LC-MS/MS at the 18-year follow-up visit. Liver function biomarkers were measured from blood samples. Multivariable regression models adjusted for demographics, BMI, alcohol use, and socioeconomic factors.
Why This Matters for Families
This study is alarming for families living near agricultural areas where glyphosate is heavily applied. The finding that young adults already show liver damage associated with glyphosate exposure underscores the urgency of reducing exposure. Families in farming communities should consider organic food choices and advocate for buffer zones around schools and homes.
