Don't eat Thai Mangur fish this monsoon: It's banned and may cause cancer
In coastal and riverine regions where fish is a dietary staple, often served with rice, selecting safe and sustainable fish is very important. However, while most fish varieties are safe and nutritious, one specific type, Thai Mangur Fish (also known as Thai Catfish) has raised serious health and environmental alarms.
Despite a government ban in place since 2000, this fish is still being illegally farmed and sold in many regions of India, putting public health at serious risk. The farming and sale of this fish are banned due to significant health risks and environmental damage, having caused a 70% decline in native fish populations and severely impacting India's aquatic ecosystem.
About the Thai Mangur fish
Thai Mangur is a hybrid variety of catfish, originally bred for its fast growth and adaptability.
It is a foreign species imported from outside India. As a carnivorous species, it endangers other fish in India, severely affecting aquatic habitats.
While it gained popularity due to its rapid growth and ease of cultivation, Thai Mangur quickly became a public health and ecological concern. So much so that its farming, sale, and consumption are now legally banned in India.
Why is Thai Mangur fish banned in India?
According to News 18, the Government of India and various regulatory bodies have prohibited Thai Mangur because of its harmful health effects and environmental hazards.
The National Green Tribunal (NGT) banned its cultivation as early as 2000, citing the fish's carnivorous nature and potential to disrupt aquatic ecosystems.
A leading voice in fisheries health and safety, the cultivation, sale, and consumption of Thai Mangur fish are not only illegal but also extremely risky to human health. Violators of this ban may face strict legal action under national laws.
Thai Mangur fish causes cancer
Dr Priyanka Arya, Assistant Director of the Aligarh Fisheries Department, warns that consuming Thai Mangur fish may increase the risk of cancer.
The fish is often reared under unsanitary conditions and fed on rotten meat mixed with spinach, a practice that contributes to serious water pollution and poses a direct threat to consumers. The fish has been linked to carcinogenic effects, making it one of the most harmful fish banned in India.
A 70% decline in native fish species
Beyond personal health, the Thai Mangur fish has caused significant damage to India's water ecosystems. Research shows that this invasive species is responsible for a 70 percent decline in native fish species in India.
Due to its aggressive, carnivorous feeding habits, the Thai Mangur preys on smaller native fish, disrupting the ecological balance in rivers, lakes, and ponds.
Additionally, Thai Mangur often carries parasites such as fish lice, which lead to epizootic outbreaks, sudden outbreaks of disease in aquaculture environments that can wipe out entire fish populations.
Illegal farming practices and water pollution
One of the many reasons why Thai Mangur is dangerous is due to its unsustainable and unhygienic farming practices.
Some fish farmers feed these fish with rotting meat waste, often laced with leftover vegetables like spinach, to maximise profit. This not only contaminates the fish but also pollutes the surrounding water bodies, accelerating the destruction of aquatic ecosystems.
Strict ban and penalties on the import of Thai Mangur fish by the government
The ban on Thai Mangur is not just advisory; it is strictly enforced. The government has made it clear that anyone involved in the cultivation, distribution, or consumption of Thai Mangur will be subject to legal penalties. Public agencies, including the Fisheries Department, have been instructed to conduct raids and take appropriate legal action against violators.
The Fisheries Department has launched multiple awareness campaigns to educate the public about the dangers of eating Thai Mangur, specifically highlighting its carcinogenic properties and harmful rearing practices.

India's fight against Sickle Cell Disease
Every year, over 3,00,000 infants are born with Sickle Cell Disease (SCD) worldwide, a genetic blood disorder which brings serious health complications. The country holds the second-highest burden of the disorder globally. An estimated 20 million Indians are affected by SCD making it a public health concern that needs urgent attention. The condition gains seriousness because of the intensity of the disease – as many as 50-90 per cent of the young patients suffering from it do not even see their fifth birthday. Sickle Cell Disease affects millions in India, with a high mortality rate among young patients. The government mission Prioritising the health of tribal communities and recognising SCD as a serious public health challenge, the Government of India launched a National Sickle Cell Elimination Mission (NSCEM) in July 2023 with the goal to decimate the disease before the country celebrates Amrit Kaal in 2047. One of the main challenges in SCD is early detection, which is covered by one of the key objectives of the mission – universal screening. The mission also promotes community-based genetic counselling. This helps families understand the risks and prevent the transmission of SCD to future generations. In addition, the mission includes awareness and education campaigns for high-risk communities. A key part of this is a national media campaign titled 'India's Fight Against Sickle Cell: From Awareness to Action', led by and HealthShots in partnership with Novo Nordisk India. Flagged off on June 19, it will culminate in a conclave – National Sickle Cell Summit 2025 – at The Lalit, New Delhi on June 30, 2025. These initiatives are important for reducing stigma surrounding the disease, promoting better understanding, and encouraging timely medical intervention. The plan also involves strengthening health infrastructure, especially at the primary healthcare level, by improving diagnostic and treatment capabilities to improve access to care and free distribution of essential medicines like hydroxyurea and folic acid through public health centres. Finally, to support ongoing improvements, the government is committed to establishing a national SCD registry and investing in research to advance disease management and care practices. The inclusion of sickle cell screening under national health missions and the involvement of frontline health workers like ASHAs and ANMs in patient follow-ups demonstrate a growing commitment to early detection and continuous care. What is SCD? SCD is a chronic genetic disorder that alters the shape and function of red blood cells in the body, causing them to become sickle shaped, stiff, sticky. These abnormal cells can block blood flow, preventing oxygen from reaching tissues. This can lead to sudden and severe episodes known as 'pain crises' which can last for hours or even days in certain cases. Those with SCD also contend with ongoing health complications like chronic anaemia, joint pains, delayed growth, shortness of breath, and extreme fatigue. Over time, virtually every organ in the body can be affected, leading to issues such as stroke, kidney and liver dysfunction, vision problems and frequent infections. The disease is most common among tribal and other ethnic groups in specific regions, commonly known as the 'sickle cell belt', which include parts of Gujarat, Maharashtra, Rajasthan, Madhya Pradesh, Jharkhand, Chhattisgarh, West Bengal, Odisha, Tamil Nadu, Telangana, Andhra Pradesh, Karnataka, Assam, Uttar Pradesh, Kerala, Bihar and Uttarakhand. The way forward Since the launch of the campaign, about 5.85 crore individuals have already been screened for SCD. The figure reflects the momentum of the campaign, which is now operational in 17 states and 278 districts. Screening initiatives have been flagged off in schools and communities to identify those at risk and health workers are being trained to identify symptoms and counsel affected families. The government aims to cover about 7 crore individuals aged between 0 and 40 years across 278 districts in India. This screening is particularly focused on tribal districts, identified as high-risk for SCD, to ensure early and accurate identification of both individuals with the disease and carriers of the sickle cell trait and also improve the care and prospects of patients suffering from the disease. The program is being executed in a 'mission mode' as part of the National Health Mission (NHM) and its implementation partners include the Ministry of Health and Family Welfare (MoHFW), the Ministry of Tribal Affairs, Indian Council of Medical Research, State Governments and Tribal Health Departments.

National Doctor's Day 2025: Theme, history, importance & why India celebrates its healers on July 1
India marks National Doctor's Day on July 1 every year to recognise the tireless service, dedication, and compassion of the country's medical professionals. The day honours the vital role doctors play in healing, protecting, and supporting communities—often at great personal cost. In 2025, the day carries even more emotional weight with its theme: 'Behind the Mask: Who Heals the Healers?'—a reflection on the mental and emotional challenges faced by healthcare workers. The theme calls on society to recognise not just the doctors' efforts but also their humanity and need for support. 'Every day, doctors prioritise the lives of others, often neglecting their own well-being. This year's theme is a reminder to care for those who care for us,' said a senior official from the Health Ministry. Why is Doctor's Day celebrated on July 1? Doctor's Day in India was instituted in 1991 by the Government of India in honour of Dr. Bidhan Chandra Roy , one of the country's most respected physicians and a visionary in public healthcare. Dr. Roy was also the second Chief Minister of West Bengal and a recipient of the Bharat Ratna. Live Events Born on July 1, 1882, and passing away on the same date in 1962, Dr. Roy's legacy includes the founding of key medical institutions like the Indian Medical Association (IMA) and the Medical Council of India (MCI). His life's work has inspired generations of doctors and continues to shape India's healthcare system. Celebrating the spirit of healing National Doctor's Day serves as a public acknowledgement of the role medical professionals play—not only during pandemics or crises but every day, across villages, towns, and cities. From general practitioners to specialists and surgeons, the day honours all those who have taken the oath to heal and serve. Various hospitals, medical institutions, and civil society organisations across the country are holding felicitation ceremonies, awareness drives, and public campaigns to appreciate the contributions of doctors. Patients and communities are also taking to social media to share stories of gratitude and hope. As India continues to face new public health challenges, National Doctor's Day 2025 is both a celebration and a call to action—to build a system where doctors are not just revered as caregivers but also protected, respected, and cared for in return.
