The Madras High Court has directed the Union Ministry of Health and Family Welfare and the Food Safety and Standards Authority of India (FSSAI) to warn customers about micro and nano plastics (MNPs) in packaged drinking water, salt, and sugar sold in PET bottles and plastic packs. A Division Bench of Justices N. Sathish Kumar and D. Bharatha Chakravarthy ordered labels on these products to carry the warning: 'This water may contain micro/nano plastics' or 'This salt/sugar may contain micro/nano plastics' in red font size 10. The Ministry and FSSAI must issue an official notification and instruct companies to comply within four weeks. FSSAI must also submit a status report by April 10, 2026. The case relates to a Tamil Nadu ban on single-use plastics and concerns over plastics entering forests in the Nilgiris and Western Ghats, affecting wildlife. An interim report by PSG Institute of Medical Sciences showed microplastics contain chemicals like Bisphenol A (BPA) that can harm hormones. BPA was found in cord blood samples above safe limits. During hearings, government counsel V. Chandrasekharan said FSSAI launched a project in March 2024 with research institutes to study microplastics as food contaminants. Initial tests on bottled water from several states and samples of salt and sugar confirmed the presence of microplastics. The study used Raman Spectroscopy and Fluorescence Imaging techniques. Though FSSAI officials said research is ongoing and inconclusive regarding harm, the court stressed the importance of consumer safety. The judges ruled that the present evidence justifies warning labels. The court said, "Safety is the primordial factor which should be considered. Until the study is finalized, the least expected of the respondent authorities is to mandate a label informing the customers that the food items... may contain micro plastics."
