HC refuses to review order on micro, nano plastics warning

1. At a Glance

• The Madras High Court dismissed the FSSAI's application to review its order. That order requires drinking water, sugar and salt sold in plastic bottles and packets to carry a bold, red-lettered warning: "This water/sugar/salt may contain micro/nano plastics." [1]
• The court says the order does not find the products unsafe. It only requires a warning so that consumers can make an informed decision before consuming them. [1]
• The case is where the consumer's right to information, the precautionary principle, inconclusive science and food-safety regulation meet. It is relevant to GS-II (judiciary, health) and GS-III (pollution, S&T).

2. Why in the News

• 28 Sept 2026 (Monday): A Special Division Bench of Justices N. Sathish Kumar and D. Bharatha Chakravarthy dismissed FSSAI's review application. [1]
• FSSAI's arguments, filed through Central Government senior panel counsel V. Chandrasekaran [1]:
• Research on the subject is inconclusive, so the warning could cause "public panic".
• The report the court relied on was only a review of papers by various scholars, and it does not conclusively establish harm to the human body.

3. Background & Evolution

• 2019: WHO published Microplastics in drinking-water. It said microplastics in drinking water do not appear to be a health threat at current levels, but that evidence on nano-sized particles is insufficient. [2][4]
• Later: WHO published Dietary and inhalation exposure to nano- and microplastic particles and potential implications for human health. [3]
• 6 Feb 2026: The Madras HC ordered the micro/nano-plastics warning label on packaged water, sugar and salt. [1]
• After Feb 2026: The Union Ministry of Health and Family Welfare (MoHFW) and FSSAI challenged the order in the Supreme Court through a Special Leave Petition (SLP). [1]
• 18 May (2026): The Supreme Court dismissed the SLP. [1]
• 28 Sept 2026: The HC dismissed the review application. [1]

4. Core Static Facts

5. Multi-Dimensional Analysis

Legal / Constitutional

• The court treated this as a disclosure remedy, not a finding that the products are unsafe. That keeps the order within judicial limits and avoids the court acting as a scientific regulator. [1]
• Because the SC dismissed the SLP, the HC direction survived the top court's scrutiny. The later review was then rejected on its merits. [1]
• The case links to Article 21 (right to health, and to information as part of informed choice) and to the precautionary principle from Indian environmental case law (static — unverified here).

Scientific / Technological

• WHO's 2019 finding was that evidence is insufficient to draw firm conclusions, especially for nanoplastics. That uncertainty is exactly what the two sides dispute. [2][4]
• Since 2019, studies have found plastic particles in several human organ systems. [6]

Governance / Ethical

• The regulator argued that a warning would cause public panic. The court favoured consumer autonomy and informed choice. [1]
• It raises the question of whether the court or the expert regulator should decide what goes on a food label.

Economic

• Packaged water, salt and sugar makers will face relabelling costs. The order may push them towards non-plastic packaging (analysis).

Environmental

• Plastic packaging is one source of micro/nano-plastics in the food chain. This connects to India's plastic waste policy (analysis).

6. Recent Developments (last 12–18 months)

• 6 Feb 2026: The HC ordered the warning labels. [1]
• 18 May 2026: The SC dismissed the SLP by MoHFW and FSSAI. [1]
• 28 Sept 2026: The HC dismissed FSSAI's review application. [1]

7. Prelims Hooks

• The warning must be in bold and red letters. [1]
• Products covered: drinking water, sugar and salt in plastic packaging. [1]
• Original direction by the Madras HC on 6 Feb 2026. [1]
• Review dismissed by a Special Division Bench (Justices N. Sathish Kumar and D. Bharatha Chakravarthy). [1]
• The SC dismissed the SLP filed by MoHFW and FSSAI on 18 May. [1]
• The HC did not hold the products unsafe. It ordered a warning for informed choice. [1]
• FSSAI's objection was that the evidence was only a review of papers, and inconclusive. [1]
• WHO's report Microplastics in drinking-water came out in 2019. [2]
• WHO: microplastics > 150 µm are likely excreted; nanoplastics may be absorbed more. [4]
• WHO says data on the toxicity of nano-sized plastic particles is insufficient. [4]
• FSSAI is a statutory body under the FSS Act, 2006 (static — unverified here).

8. Why a Label on Plastic Packets May Point at the Wrong Culprit

• Loose salt and sugar also contain microplastics
• In 2024, the research group Toxics Link tested 10 kinds of salt and 5 kinds of sugar in India. It found microplastics in every sample, big brand or small, packaged or unpackaged [7].
• The order puts the warning only on products sold in plastic bottles and packets [1].

• A buyer may read this as "the packet is the problem" and move to loose salt or sugar. That would not remove the risk [7].

• The plastic often gets in before the packing

• The particles found were fibres, pellets, films and fragments, from 0.1 mm to 5 mm in size [7].
• Rock salt had the fewest (6.70 pieces per kg). Iodised salt had the most (89.15 pieces per kg) [7]. So the type of salt and how it is made matter, not only what it is packed in.
• A label based only on the packaging tells the buyer part of the story, and may point them the wrong way.

9. FSSAI's Strongest Argument — and Where It Falls Short

• The strongest case against the label
• WHO found that microplastics in drinking water do not appear to be a health threat at current levels. Particles bigger than 150 µm (micrometre, one-thousandth of a millimetre) mostly pass out of the body [2][4].
• A warning with no number and no safe limit gives the buyer nothing to act on. It can only worry them. That is the core of FSSAI's "public panic" argument [1].

• Water, salt and sugar are essentials. Nearly all of it is sold packed, and even loose salt and sugar carry microplastics [7]. So the buyer's "informed choice" is mostly between one product that may contain microplastics and another that also does.

• What is right about it

• The label does not help the buyer find a safer product. It only tells them the risk exists. The point about "informed choice" is weaker than the court suggests.

• Why the label still holds up

• The wording is "may contain", not "is harmful". It states a fact the evidence supports [1][7].
• WHO did not call microplastics safe. It said the data on nanoplastics is not enough, and smaller particles may be absorbed into the body more easily [4].
• FSSAI's own research project calls micro- and nano-plastics "emerging food contaminants" [8]. It is hard to call a warning "panic" when the regulator itself uses that term.
• The precautionary principle (act to prevent harm even before science is certain) exists for exactly this gap between "not proven harmful" and "proven safe".

10. Why the Regulator Cannot Yet Set a Safe Limit

• There is no agreed way to measure the plastic yet
• FSSAI started a project only in March 2024. Its goal is to develop and validate methods to detect micro- and nano-plastics in food [8].
• Without one standard test, two laboratories can give different counts for the same sample. So a legal limit cannot be enforced.

• The project also has to produce India's first data on exposure (how much plastic a person actually takes in) [8]. A safe limit cannot be set without it.

• So the court filled an empty space

• The regulator had no standard, no limit and no label rule of its own.

• A disclosure order was the only tool that did not need a scientific finding first [1]. This also answers the "court versus expert" question: the expert had not yet acted.

• Global science has the same gap

• WHO's 2019 report also called for standard methods to measure microplastics, because studies used different methods and could not be compared [2].

11. What Should Happen Next, and Who Should Do It

• FSSAI should finish its method project and publish the data
• The March 2024 project works with CSIR-Indian Institute of Toxicology Research, ICAR-Central Institute of Fisheries Technology and BITS Pilani [8].

• Once the test methods are validated, FSSAI can replace the general "may contain" line with a rule based on test results. This is the lasting answer to the court's order.

• FSSAI should cover loose products, not only plastic packets

• The Toxics Link study shows unpackaged salt and sugar also carry microplastics [7]. Standards should apply to the product itself, whatever it is packed in.

• Water treatment and pollution control should target the source

• WHO advises that the bigger health priority is controlling plastic pollution and treating water properly. Conventional treatment removes most particles [2][4].
• This links the labelling case to India's plastic waste rules, which control plastic at the source.

12. Anchors for Answers

• Data: Microplastics found in all 10 salt and 5 sugar samples tested in India; iodised salt highest at 89.15 pieces/kg, sugar 11.85–68.25 pieces/kg (Toxics Link, 2024) [7]
• Data: 9,029–174,959 microplastic particles swallowed per person per year from drinking water (synthesis of 59 studies) [5]
• Report/Committee: WHO, Microplastics in drinking-water (2019): no clear threat at current levels, but not enough data on nanoplastics [2][4]
• Report/Committee: Toxics Link, Microplastics in Salt and Sugar (2024) [7]
• Law/Case: Article 21 (right to health); Food Safety and Standards Act, 2006; precautionary principle (Vellore Citizens' Welfare Forum); Madras HC order of 6 Feb 2026, SLP dismissed 18 May 2026 [1]
• Scheme: FSSAI project "Micro- and Nano-Plastics as Emerging Food Contaminants" (March 2024), which is building test methods and exposure data with CSIR-IITR, ICAR-CIFT and BITS Pilani [8]

13. Mains Relevance

• GS-II: Health; statutory regulatory bodies; the judiciary (judicial activism versus regulatory expertise).
• GS-III: Environmental pollution (plastics); S&T in everyday life.
• GS-IV: Consumer autonomy versus paternalism; ethics of disclosure when science is uncertain.
• Question stems: 1. "Mandatory disclosure is a proportionate response to scientific uncertainty." Discuss with reference to the Madras HC's micro/nano-plastics labelling order. 2. Examine the health and environmental risks of micro- and nano-plastics. How well equipped is India's food-safety framework to respond? 3. Should courts direct food-labelling norms when an expert regulator exists? Critically analyse.

15. Common Errors / Trap Areas

• Wrong: "The HC declared packaged water/salt/sugar unsafe." Correct: it ordered only a warning for informed choice. [1]
• Wrong court sequence: the SC dismissed the SLP (May) before the HC dismissed the review (Sept). [1]
• Wrong ministry: FSSAI works under the MoHFW, not the Ministry of Consumer Affairs or the MoEFCC (static — unverified here).
• Misreading WHO: the 2019 report did not declare microplastics safe outright. It flagged insufficient data, especially on nanoplastics. [2][4]
• Size confusion: microplastics are < 5 mm and nanoplastics < 1 µm. Do not mix up the thresholds (static — unverified here).
