The US Department of Agriculture has announced new measures to monitor the spread of bird flu among dairy cows, following concerns over its impact on poultry and dairy herds. With over 400 dairy herds affected, the virus was found in cows earlier this year, sparking concerns of its spread through the milk supply. The USDA's decision includes testing lactating cows and restricting their interstate movement, as well as ongoing measures to ensure the safety of pasteurized milk for human consumption.
Avian Influenza Outbreak Raises Concerns for Dairy Industry
The United States Department of Agriculture (USDA) has announced new measures to mitigate the spread of avian influenza (bird flu) among dairy cows amid concerns about its potential impact on the poultry and dairy industries.
Background
Avian influenza is a highly contagious viral disease that affects birds, including poultry, waterfowl, and wild birds. The current outbreak of highly pathogenic avian influenza (HPAI) in North America has resulted in the loss of over 50 million poultry birds since February 2023.
Impact on Dairy Cows
While avian influenza is primarily a disease of birds, it has recently been detected in dairy cows in several US states. The virus can be transmitted from infected birds to cows through direct contact or contaminated surfaces.
Safety of Milk Supply
The USDA emphasizes that pasteurized milk remains safe for human consumption. The pasteurization process kills any bacteria or viruses, including avian influenza virus. However, there is concern that the virus could potentially affect the quality and safety of raw milk from infected cows.
USDA Measures
To address these concerns, the USDA has implemented the following measures:
Top 5 FAQs and Answers
Can avian influenza spread to humans through milk? No, pasteurized milk is safe for human consumption, as the pasteurization process kills any potential viruses, including avian influenza virus.
Is raw milk safe to consume during an avian influenza outbreak? No, it is not recommended to consume raw milk during an avian influenza outbreak, as the virus could potentially be present in the milk from infected cows.
What are the symptoms of avian influenza in dairy cows? Symptoms may include respiratory distress, coughing, sneezing, lethargy, and loss of appetite.
How do dairy farmers prevent the spread of avian influenza? Farmers can implement biosecurity measures such as using protective gear, disinfecting equipment, and isolating infected animals.
What is the economic impact of avian influenza on the dairy industry? The outbreak has led to the loss of dairy cows and disruption of milk production, which could have significant economic consequences for the industry.
On the birth anniversary of Dr. APJ Abdul Kalam, the ‘Missile Man’ of India, tributes pour in on social media celebrating his life, vision and impact. A visionary scientist, inspiring leader and true patriot, Dr. Kalam's humility, compassion and constant interaction with students continue to inspire generations. His tireless efforts in defense, science and youth empowerment have strengthened India's path towards self-reliance and his legacy continues to motivate young minds to dream big and work hard for the nation.
Recent studies have found that extreme heat, particularly when combined with high humidity, can have a significant impact on mental health. A study in India showed that when wet bulb temperature exceeded 27°C, the probability of reporting severe depression increased by 0.5%, even when the temperature was slightly lower. This finding is consistent with global reviews that have linked high temperatures to mood disorders, increased hospital admissions for psychiatric conditions, and even elevated suicide risk. The Lancet has also published evidence that rising temperatures worldwide are a growing threat to emotional and cognitive health.
In a meeting with university officials in Udaipur, Rajasthan Governor Hari Bhau Bagde stressed the importance of incorporating India's ancient knowledge traditions into academic research. He highlighted the deep repository of knowledge in India since ancient times and urged scholars and scientists to draw upon this tradition in their work. Bagde also suggested making ancient texts available in university libraries for study and research purposes, in order to shape the intellectual abilities and love for the nation among the younger generation.
John Clarke, Michel H. Devoret, and John M. Martinis have been awarded the 2025 Nobel Prize in Physics for their pioneering research into quantum mechanical tunnelling. Their discovery has opened new possibilities for quantum technologies, and will be formally presented on December 10, the anniversary of Alfred Nobel's death. This announcement follows the tradition of recognizing transformative contributions to science, and the award carries a prestigious prize of 11 million Swedish kronor.
The US-Japanese trio of Mary E Brunkow, Fred Ramsdell, and Shimon Sakaguchi have won the 2025 Nobel Prize in physiology or medicine “for their discoveries concerning peripheral immune tolerance". Through their research, they have shown how the immune system is kept in check and why serious autoimmune diseases do not affect everyone. Sakaguchi found a new class of T cells, while Brunkow and Ramsdell discovered the explanation behind a specific mouse strain's vulnerability to autoimmune diseases. Together, they have significantly advanced our understanding of immunology and autoimmune diseases.
Indian astronaut Shubhanshu Shukla, who recently completed a 20-day space mission, shared his insights and experiences at the convocation ceremony of Dr. APJ Abdul Kalam Technical University. He highlighted the importance of patience, focus, and the inevitability of change in achieving success, and urged the graduating class to actively contribute to shaping a fearless and ambitious India.
The Regional Meteorological Centre (RMC) in Chennai has issued a weather alert for parts of Tamil Nadu, with thunderstorms and light to moderate rainfall expected on Saturday. The alert was issued due to the strengthening of a cyclonic circulation in the Bay of Bengal, which is likely to intensify and form a low-pressure area. The system is expected to affect Tamil Nadu, Puducherry, and Karaikal, with some areas experiencing heavy rainfall and gusty winds. The public is advised to stay updated and take precautions, especially in hilly and western districts.
As a step towards advancing India's deep-sea research capabilities, the Union Science Minister announced a landmark contract with the International Seabed Authority to conduct mineral exploration in the Indian Ocean for the next 15 years. This move will not only help India in expanding its scientific knowledge about the deep sea but also has the potential to strengthen its position as a leading player in the international seabed mining industry.
President Trump has signed a proclamation that makes significant changes to the H-1B visa program. These changes include a new $100,000 fee for employers to sponsor H-1B workers entering the US, as well as higher wage levels and priority for senior, high-paying positions. While workers currently inside the US on valid H-1B status are not directly affected, anyone traveling abroad and seeking re-entry must comply with the new requirements. The lasting impact on the flow of talent, technology, and jobs between India and the US remains uncertain.
On September 7, 2025, a total lunar eclipse, known as a "Blood Moon," was visible to sky-watchers across Europe, Africa, Asia, and Australia. This event, which lasted from 8:58 pm to 2:25 am in India, is the longest total lunar eclipse since 2022 and only the second clearly visible Blood Moon in India since 2018. The Moon appeared red due to the Earth's atmosphere bending sunlight and filtering out blue light, providing ideal viewing conditions for Indian observers in the late evening and early hours of September 8.
