Key Update

Fruits are widely recommended as part of a healthy diet. However, their outer surfaces may sometimes carry pesticide residues, raising concerns about long-term health exposure. A study published in the International Journal of Hygiene and Environmental Health suggests that regular consumption of certain fruits and vegetables may increase pesticide levels detected in the body.

What the Study Found

The study found that people who frequently consumed produce such as strawberries, spinach and bell peppers had higher pesticide biomarkers in their bodies, indicating exposure through diet. Researchers analysed pesticide residue data from the United States Department of Agriculture along with biomonitoring data from the Centres for Disease Control and Prevention. The results suggest that pesticide residues present on fruits and vegetables can enter the body and be detected through biological testing. Long-term exposure to certain pesticides has been associated with health risks such as hormone disruption, reproductive issues and increased cancer risk.

Common Fruits May Also Carry Residues

Separate reports published in the Sustainability indicate that several widely consumed fruits—including apples, grapes, mangoes and pomegranates—often receive multiple pesticide treatments during cultivation. In some cases, treatment rates approach nearly 100%, increasing the likelihood of residue presence on the fruit surface.

Why This Matters for India

Pesticide use is common in agriculture because pests can destroy 20–30% of crop production. According to the Indian Council of Medical Research and the Indian Council of Agricultural Research, pesticide residues are still detected in some food commodities in India. Monitoring data show that about 21.7% of fruit samples contain pesticide residues, while around 1.1% exceed the limits set by the Food Safety and Standards Authority of India.

Who May Be More Vulnerable

Certain groups may be more sensitive to pesticide exposure, including:

• Children, whose bodies are still developing
• Pregnant women, where exposure may affect fetal development

Reducing exposure is therefore important, especially for these vulnerable groups.

Reducing Pesticide Residues at Home

Consumers can lower pesticide intake with simple precautions:

• Wash fruits and vegetables thoroughly under running water
• Soak produce in salt water or a baking soda solution to remove surface residues
• Peel fruits like apples when possible
• Eat a varied diet to avoid repeated exposure to the same pesticides.
