3 children dead despite rabies vaccine, questions over quality control in Kerala
The death of three vaccinated children due to rabies in the past month has raised concerns in Kerala and prompted state health minister Veena George to assure that the state uses vaccines only after quality tests.
The latest victim, seven-year-old Niya Faisal, died at SAT Hospital in Thiruvananthapuram on Monday. She was administered three doses of the anti-rabies vaccine earlier.
On April 9, a 12-year-old girl from Pathanamthitta district died of rabies despite taking the vaccine, and on April 29, a five-year-old girl succumbed to rabies, again after being vaccinated.
In all three cases, the victims sustained deep injuries to their heads and hands. 'The virus usually sticks to the wound. However, when bitten on the face and hands, where there are more nerves, the animal's saliva is more likely to come into contact with the nerves. In such cases, the virus can enter the nerves before we can do anything. To prevent the virus from reaching the nerves and to reduce the risk, the wound should be washed with soap and water. If that does not happen, the virus may reach the nerves by the time the patient is taken to the hospital,' she said.
The minister said the government had in 2022 formed an expert committee to look into the efficacy of anti-rabies vaccines, and samples collected from vaccinated people showed they all had antibodies as per the prescribed standards.
'Hospitals in Kerala use vaccines only after a quality test at Central Drugs Laboratory in Kasauli (Himachal Pradesh), and each batch is tested at the lab and supplied in Kerala only after ensuring quality,' she said.
Opposition leader V D Satheesan said the death of the three children is a matter of concern. 'In the last five years, of 102 persons who died of rabies, 20 had been vaccinated. Despite the repeated deaths, the health department claims the vaccines are safe. Innocent children are being made scapegoats for the corruption of the health department,' he claimed.
As per government data, as many as 1,69,906 doses of anti-rabies vaccine have been administered to people bitten by dogs, cats, or other animals.
Till May 2 this year, the state has reported 13 deaths due to rabies. In 2024, the number of confirmed deaths was 22 and suspected four. In 2023, the state had 17 confirmed rabies deaths and eight suspected ones.
The Lancet, in an article published in 2023, raised concerns over rabies deaths in Kerala among vaccinated individuals. The article, Emergence of rabies among vaccinated humans in India: a public health concern, said deaths among vaccinated individuals were due to the nature of wounds and failure to seek prompt care.
'Awareness about first aid measures after an animal bite in the country is inadequate. In a survey in six Indian states, only 38 per cent of victims of animal bites reported washing wounds after biting with soap and water,' said the paper published in The Lancet.
The 2022 report said that the number of infected dogs has doubled in the past five years. 'Among 300 samples taken from dogs, 168 samples (56%) were found to be positive for rabies, compared to 32% in a similar study conducted in 2016. The state has reported more than 200,000 dog bite cases and 21 deaths (12 deaths were laboratory confirmed) in 2022 which is almost double the deaths reported during 2021,' it said.
The report said that, considering the increase in animal bite cases and rabies deaths, Kerala should consider giving a course of rabies vaccination before potential exposure to the virus, which is known as pre-exposure prophylaxis for rabies, as a temporary measure until canine control is achieved.

How to Decode Adulteration in Tea: What Every Consumer Should Know
Tea is more than just a drink; it's a ritual steeped in history and a source of comfort for millions around the world. However, as we sip from our cups, we often take for granted the purity and authenticity of what we're consuming. The issue of adulteration in loose tea has emerged as a significant concern, threatening to undermine the quality of this beloved beverage. Understanding the risks associated with adulteration and learning how to recognise genuine loose tea is crucial for ensuring an authentic and safe tea experience. Understanding Adulteration in Tea Adulteration in tea involves the addition of harmful substances to tea leaves, often with the intent to enhance the tea's appearance with respect to color or flavour. This deceptive practice may include the use of unauthorised colours, flavours, or even other plant materials, which may make the tea seem more appealing to the untrained eye or nose. However, these additives not only undermine the tea's purity but also pose significant health risks. For instance, synthetic colorants like carmine, brilliant blue, sunset yellow, and tartrasine are sometimes added to damaged or lower-quality tea leaves to improve their appearance. These substances, however, are not permitted and can be harmful when consumed. The Tea Board of India has been proactive in raising awareness about these adulteration practices. The Board has emphasized the dangers posed by chemically colored teas, which have unfortunately gained a foothold in the Indian market. The use of synthetic dyes in tea is strictly prohibited, as per regulations, yet they continue to be a concern. These adulterants are often used to treat tea leaves that have been damaged during processing, making them appear more marketable, despite their lack of nutritional value. Why Are Colours added to tea? The primary reason for the use of additives and coloring agents in tea is to treat leaves that have been damaged during the tea-making process. According to the Tea Board of India, these damaged leaves are of low quality, and to make them marketable, additives are added to enhance their color. However, these additives do not add any nutritional value to the tea and are strictly prohibited due to their potential health risks. The Food Safety and Standards Authority of India (FSSAI) has made it clear that the use of coloring substances in tea is not allowed. The treatment of tea with coloring agents falls under the category of adulterants, and such practices have become a matter of serious concern. Recognizing Adulterated Tea Through a Simple Cold-Water Test A simple yet effective test can help reveal the authenticity of loose tea. Place a small amount of tea in a clear glass of water. Genuine tea leaves will gradually unfurl and expand, releasing their natural color slowly as they infuse. If the tea leaves remain unchanged or if the water quickly turns an unnatural color, this could be a sign of added artificial colorants or other additives. A proper infusion should result in clear water with visibly expanding tea leaves that change in texture as they steep. Loose Tea vs. Packaged Tea Loose tea, especially when purchased from unverified sources, may pose a greater risk of adulteration. Its bulk sale and lack of detailed labeling make it harder to assess quality and authenticity. In contrast, reputable packaged tea brands typically invest in rigorous quality control measures to ensure their products are genuine. These brands often provide comprehensive information about their sourcing and processing practices, offering consumers greater confidence and transparency in their purchases. Researching the Source Ensuring the quality of your tea starts with buying from reputable and trustworthy sources. Brands that are transparent about their sourcing processes and utilize third-party testing are generally more reliable and less likely to offer adulterated products. To avoid questionable teas, investigate the origin of the tea and the credibility of the supplier. Look for certifications and customer reviews that validate the tea's authenticity and quality. Reliable suppliers typically offer detailed information about their sourcing methods and quality control practices, providing you with peace of mind about your purchase. Making Informed Choices For tea enthusiasts, understanding the risks of adulteration in loose tea is crucial to preserving the authenticity of their tea experience. By learning to identify the signs of adulteration and distinguishing between loose and packaged tea, consumers can make more informed decisions and support the market for high-quality, genuine tea. Navigating the tea world requires attention to detail and a bit of research. With the right knowledge, you can savor each cup with confidence, knowing that you're enjoying a beverage that is both authentic and delightful. By staying vigilant and informed, you not only protect your tea-drinking experience but also contribute to the appreciation and demand for high-quality tea.

Feeding the Family Right This Summer: Smarter Protein Choice - U.S. Turkey for All Ages
SMPL New Delhi [India], June 13: As the summer sun shines brighter and our routines shift to match longer days and lighter appetites, it becomes even more essential to revisit what's going on our plates--especially when it comes to protein. Whether it's growing kids on school break, busy professionals juggling travel plans, or elderly family members looking for digestible meals, one thing is clear: protein remains a non-negotiable part of a balanced summer diet. "Turkey is an excellent example of a lean meat that supports high-quality protein intake without adding unnecessary saturated fat," says Gunja Chatwal, Nutritionist. She further adds, "Especially during summer, when digestion slows and appetite fluctuates, proteins like U.S. turkey provide sustained energy, aid muscle repair, and help regulate blood sugar levels--all while being light and versatile." "Turkey, especially from the U.S., is a high-quality, lean protein source that fits seamlessly into the Indian summer table. Unlike heavier meats that can feel dense and difficult to digest in hot weather, turkey is light on the stomach but rich in nutrition, making it perfect for all age groups," says Devna Khanna, In-Country Marketing Representative, USA Poultry & Egg Export Council (USAPEEC). Growing children need a regular supply of protein for development, especially during the summer when outdoor play and activities increase. Whether you're working from home, commuting to the office, or enjoying a family vacation, turkey is a wonderful way to stay full without feeling sluggish. It's high in protein but low in fat, making it a smart pick for those watching their weight or seeking to stay fit during the season. U.S. Turkey is a soft, easily chewable meat that is gentle on digestion--good for those who often prefer lighter meals. The beauty of U.S. turkey lies in its culinary adaptability. It can be seasoned with Indian spices, grilled, shredded, or lightly sauteed for use in salads, rolls, thalis, and even comfort dishes like biryani, kathi rolls, or kebabs. Its mild flavor allows it to blend well with traditional Indian recipes without overpowering the dish. What set U.S. Turkey apart are the strict quality control, safety standards, and sustainability practices it follows in production.
