How a Banned Chemical Still Reaches Your Plate

You are not just eating a chemical; you are eating a nutritionally hollowed version of the fruit you paid for. Every summer, as temperatures climb and school breaks begin, India's fruit markets transform. Mango pyramids glow amber at every corner stall. Bananas arrive in perfect, uniformly yellow bunches. Papayas look like they've been plucked at precisely the right moment. For consumers, it looks like abundance. For food safety regulators, it looks like a red flag. India produces around 18 million tonnes of mangoes every year, making it one of the world’s largest producers, according to MarkNtel Advisors (2024). Demand peaks during the summer months, when nearly 70 per cent of India’s tropical fruit trade takes place, says the FAO Tropical Fruit Report. To speed up ripening, some traders still use calcium carbide despite an FSSAI ban since 2011. The chemical can ripen fruit in 24–36 hours, compared with four to seven days naturally. Seasonal demand puts enormous pressure on fruit supply chains and creates a predictable temptation to take shortcuts. Traders call it masala. Regulators call it calcium carbide. When the compound touches moisture, it releases acetylene gas, a crude chemical analogue of ethylene, the natural hormone that ripens fruit. Tuck a few sachets into a crate of raw mangoes, and within 24 to 36 hours, the fruit looks market-ready. Nature takes four to seven days. Carbide takes one night. At a fraction of the cost. Industrial-grade calcium carbide is not a food substance. It carries toxic impurities, chiefly arsenic and phosphorus that can leach onto fruit surfaces and be ingested. FSSAI has documented a range of health effects: dizziness, vomiting, difficulty swallowing, skin ulcers, and, with prolonged or repeated exposure, neurological disorders, hypoxia, and memory loss. You are not just eating a chemical; you are eating a nutritionally hollowed version of the fruit you paid for. Children and pregnant women are most at risk. And yet, despite a ban in place since 2011, carrying penalties of up to one year's imprisonment and fines of up to ₹3 lakh, the practice runs openly across India's unorganised fruit trade. Here is the part that makes it almost impossible to fight at the consumer level: calcium carbide leaves no trace visible to the naked eye. No smell. No discolouration. Nothing that would tip off even the most cautious buyer at a mandi or street stall. The only reliable tell is in the flesh: carbide-ripened fruit ripens from the outside in, leaving the interior pale, starchy, and underripe while the skin signals otherwise. If the mango looks perfect but tastes like nothing, ask questions.While directives are necessary, enforcement remains incomplete without laboratory infrastructure. The real solution lies in building systematic testing checkpoints at the mandi level, where rapid, on-site screening flags suspect consignments before they reach the retail shelf. Labs should work with accredited methods that can detect carbide residue markers within hours. That science needs to become a standard feature of the supply chain, not an emergency response. In a directive dated April 16, 2026, the FSSAI ordered all State and UT food safety commissioners and regional directors to intensify inspections of mandis, storage facilities, and distribution hubs. The enforcement teams have been authorised to use strip paper tests to detect acetylene gas on-site. FSSAI also flagged a parallel concern: food business operators were found dipping fruits directly into liquid ethephon solutions, a shortcut that violates the regulation requiring ethylene to be used only as a gas in approved, controlled ripening chambers. Raids in Hyderabad, Delhi, Uttar Pradesh, and Haryana have already led to seizures of treated fruits and unlicensed chemicals and, in some cases, arrests on-site. The directive is necessary. It is not sufficient. Calcium carbide has survived fifteen years of prohibition not because regulators haven't tried, but because the economics of enforcement have never consistently outweighed the economics of the shortcut. That changes only when testing becomes routine: not seasonal, not reactive, but embedded at every critical node of the supply chain. Until then, the most dangerous thing about the fruit on your table isn't what you can see. It's what you can't. (The writer is the Founder and CEO of Equinox Labs. Views personal.)

Violent Endgame

The shocking murder of BJP leader Suvendu Adhikari’s closest aide Chandranath Rath on a public road in Madhyamgram, immediately aftert he BJP scored a historic landslide in the West Bengal Assmebly election by toppling Mamata Banerjee’s Trinamool Congress, is not merely another political killing in the state. It is the logical culmination of a culture of gangsterism that has flourished under Mamata Banerjee’s rule for over a decade and a half. Bengal has long witnessed violence. The Left perfected intimidation. But the Trinamool Congress has industrialised it.


Rath was not some obscure political worker caught in the crossfire of local rivalries. He was one of Adhikari’s closest associates, a former Indian Air Force man who became integral to the BJP’s organisational machinery in Bengal. He handled sensitive electoral operations, strategic coordination and back-end management during some of the fiercest political battles in the state, including the campaign that humiliated Mamata Banerjee in Bhabanipur. His murder could hardly be called random.


The unanswered questions are chilling. Was Rath himself the target? Or was this a message meant for Suvendu Adhikari, who is touted as the next Chief Minister of the state?


That is what makes this murder so sinister. The BJP’s sweeping victory should have marked the beginning of democratic transition and political sobriety. Instead, Bengal appears trapped in the dying convulsions of a violent regime unwilling to accept defeat. This has been embodied in the violent rhetoric of top TMC leaders including Mamata’s nephew, Abhishek Banerjee, who has openly expressed his defiance of the Centre and threatened revenge. The scenes unfolding in Bengal today resemble less the aftermath of an election and more the collapse of an entrenched authoritarian order desperately clinging to relevance.


Mamata Banerjee and Abhishek Banerjee are responsible for the poisonous climate they have nurtured. For years, Trinamool leaders and foot soldiers operated with near-total immunity. Political opponents have regularly been beaten, intimidated or worse murdered.


Even more dangerous has been the cynical communal appeasement woven into this politics. The rhetoric surrounding Mamata Banerjee’s defeat has exposed deeply troubling fault lines. Statements from extremist voices across the border in Bangladesh, openly urging Mamata Banerjee to lead West Bengal in breaking away from India, have become routine. The TMC government that spent years pandering to sectarian elements has weakened institutional authority while emboldening dangerous actors who increasingly view the state as politically penetrable and strategically vulnerable.


The next BJP government cannot behave as though Bengal merely requires administrative correction. It requires moral and institutional reconstruction. The criminal-political nexus built over fifteen years must be dismantled without hesitation. Every politically protected gangster, extortionist, riot-instigator, and murder operative must face relentless prosecution.


Chandranath Rath will not stand beside Suvendu during the oath-taking ceremonies of a new political era. But his murder may yet become the moment Bengal finally recognises the monstrous system that has ruled it for far too long.
