Animal-derived foods such as milk, meat, eggs, and fish provide humans with essential nutrition and are widely consumed across the world. These foods are rich in proteins, vitamins, and minerals. However, if proper hygiene is not maintained during production, processing, storage, or transportation, such foods may become contaminated with harmful microorganisms, including viruses.Viruses are microscopic infectious agents that cannot be seen with the naked eye. When contaminated food is consumed, these viruses may enter the human body and cause illnesses such as diarrhoea, vomiting, abdominal pain, fever, and gastroenteritis. Therefore, detection and monitoring of viruses in animal-origin foods are extremely important for ensuring food safety and protecting public health. This article explains the major methods used for viral detection in food samples, including ELISA, Latex Agglutination, RT-PCR, and Agarose Gel Electrophoresis, in simple language.

Water scarcity and rising cultivation costs have increased the need for efficient irrigation methods in Indian agriculture. Conventional surface irrigation practices such as flood, basin, and furrow irrigation often result in low water-use efficiency, uneven water distribution, and soil-related problems. In this context, rain-gun sprinkler irrigation offers a practical and efficient alternative for irrigating large agricultural fields. A rain-gun system applies water in the form of artificial rainfall through a high-pressure rotating nozzle, enabling uniform water application over a wide area within a short time. The system consists of key components such as pipelines, connectors, valves, filters, and a tripod-mounted rain gun, and may be used in portable or fixed form depending on field conditions. Rain-gun irrigation is suitable for crops like sugarcane, maize, cotton, groundnut, pulses, vegetables, and fodder, particularly in medium to large fields with sandy loam and loamy soils. Field experiences indicate improved water-use efficiency, reduced labour requirement, and better coverage compared to conventional surface irrigation. Although adoption is influenced by factors such as energy requirement and wind sensitivity, government support through subsidy schemes and growing awareness of water-saving technologies highlight the potential of rain-gun irrigation for sustainable water management in Indian agriculture.

India possesses vast and diverse inland fisheries and aquaculture resources that play a crucial role in supporting livelihoods, food and nutritional security, poverty alleviation and economic development. Inland fisheries contribute significantly to employment generation, income diversification and value addition, particularly for rural and marginalized communities, including women. The sector also supports ecosystem services, biodiversity conservation and national economic growth through trade, taxation and contributions to gross domestic product. Despite its immense potential, the effective use of fisheries for poverty alleviation faces multiple challenges, including resource constraints, overexploitation, destructive fishing practices, post-harvest losses and inadequate adoption of ecosystem-based management approaches. Global initiatives such as the FAO?s Blue Transformation framework highlight the need for sustainable and inclusive management of aquatic food systems. Addressing these challenges through responsible fisheries management, value addition, livelihood diversification and policy support can enhance the sector?s contribution to poverty reduction, food security and sustainable development in India.

Squalene is natural potent antioxidant present in vegetable oil, fish liver oil, palm oil, grain amaranth, buckwheat etc. It is mainly used in skin care products due to photoprotective agent and strongly quenches free radicals. Commercially squalene is derived from deodorized distillate from the refining of vegetable oil followed by extraction either by solvent or super critical fluid extraction method. Micronized squalene emulsions are being used as immune adjuvant, treat the COVID 19. Natural source of squalene served the functions of nutraceuticals i.e. prevention and treatment of CVD, improves the immunity, increase the GSH, CAT, SOD hormones to quenches the free radicals in cellular level. Squalene's potential health benefits are attributed to its antioxidant, anti-inflammatory and cardio protective properties, among others. Hence, the consumption of squalene rich foods can boost immunity, improve skin health and also maintain healthy life style.
