Study finds uranium traces in breast milk across six Bihar districts, raising major health alarm

A multi-year scientific study has revealed the presence of toxic uranium in breast milk samples collected from lactating mothers in Bihar, exposing newborns to severe health risks.

A startling scientific investigation has found toxic uranium in breast milk samples from lactating mothers across six districts in Bihar, revealing one of the most alarming public health concerns the state has faced in recent years. The study, published in a globally recognised scientific journal, shows that newborns may be exposed to dangerous contamination directly through breastfeeding.

The research, conducted under the leadership of Dr. Ashok Sharma, analysed breast milk samples collected between 2021 and July 2024 from women aged 17 to 35. Samples were taken from Bhojpur, Samastipur, Begusarai, Khagaria, Katihar and Nalanda. According to the findings, uranium was detected in every single sample reviewed during the study period.

Among the districts, Khagaria recorded the highest overall concentration of uranium, while Nalanda showed the lowest levels. However, one of the individual samples from Katihar carried the highest uranium level recorded in the entire study. Experts highlight that there is no approved safe limit for uranium in breast milk, making the results even more alarming.

The study points to groundwater contamination as a likely cause. Bihar has long struggled with unsafe underground water, and the findings suggest that toxic elements are now entering the food chain through mothers. With breast milk being the primary source of nutrition for infants, the discovery reveals a disturbing pathway of exposure.

Health risk assessments conducted as part of the study warn that nearly 70% of affected newborns could face potential carcinogenic complications later in life. The Geological Survey of India has begun examining the underlying reasons behind the rising contamination levels.

The findings highlight a severe environmental and public health emergency. What should have been the safest and most natural source of nourishment for infants is now carrying harmful toxins into their bodies. The revelation has intensified calls for urgent investigation, groundwater testing and immediate intervention to protect vulnerable infants across the affected regions.
