Nothing says summer like a juicy, sweet mango. But with reports of artificially ripened mangoes being seized across India, are you sure the ones you’re eating are safe?
In May 2024, the Food Safety and Standards Authority of India (FSSAI) seized 575 kg of mangoes worth Rs 72,000 from fruit stalls in Coimbatore. These mangoes were found to have been ripened using ethylene sachets in an unapproved manner. Similarly, in Vellore, Tamil Nadu, 1.5 tonnes of mangoes were confiscated after being artificially ripened with chemical agents.
Here’s everything you need to know about calcium carbide, its risks, and simple ways to check if your mangoes are safe to eat.
Why do sellers use chemicals on mangoes?
Mangoes naturally ripen when they release ethylene gas, a harmless plant hormone. However, the process takes time, and traders looking to make a quick profit often use calcium carbide to speed up ripening unnaturally.
When exposed to moisture, calcium carbide produces acetylene gas, which mimics ethylene and forces mangoes to ripen faster. However, this method comes with severe health risks.
Is calcium carbide harmful?
Absolutely. FSSAI has banned the use of calcium carbide due to its toxic effects. The chemical contains traces of arsenic and phosphorus, which can cause:
- Vomiting and diarrhoea
- Skin ulcers and eye damage
- Neurological issues like dizziness and memory loss
- Difficulty breathing and lung problems
- An increased risk of cancer

Despite the ban, reports indicate that calcium carbide is still being used across India. This makes it crucial for consumers to identify artificially ripened mangoes before buying or consuming them.
How to identify artificially ripened mangoes
1. The water test
This is the easiest way to check for artificially ripened mangoes. Simply drop a mango into a bucket of water.
– If it floats, it’s likely chemically ripened.
– If it sinks, it’s natural.
2. Check the colour
Naturally ripened mangoes have a uniform yellow-orange hue. Artificially ripened ones may have an uneven colour, with green patches or an overly bright yellow appearance.

3. Feel the texture
Mangoes ripened with chemicals often feel too soft and squishy, while natural mangoes have a firm but tender texture.
4. Taste it to check
If a mango leaves a slight burning sensation in your mouth or throat, it may contain harmful chemicals.
What you can do
- Buy mangoes from trusted local farmers or organic stores.
- Wash mangoes thoroughly before eating to remove surface chemicals.
- If you suspect a vendor is selling chemically ripened mangoes, report them to the Food Safety Department via WhatsApp at 9444042322.
While mangoes are a delicious summer treat, staying informed can help you enjoy them safely.
