As the world faces an escalating protein crisis amid climate change, population growth, and resource scarcity, edible insects have emerged as a transformative solution for sustainable food and feed systems. With over 2000 known edible species, insects offer a nutrient‐rich alternative to conventional livestock, providing protein levels between 30% and 85%, essential amino acids, beneficial fats, and bioavailable micronutrients often exceeding those found in meat or fish. Compared to traditional farming, edible insect production emits up to 100 times fewer greenhouse gases and requires 50%–90% less land and water, aligning closely with global circular bioeconomy goals. Economically, the global edible insect protein market was valued at USD 483.1 million in 2023 and is projected to reach USD 2 billion by 2030. Yet, large‐scale adoption faces critical barriers, including cultural resistance, food safety concerns, and fragmented regulatory landscapes. Risks such as microbial contamination, allergenicity, and heavy metal accumulation demand stringent food safety protocols and harmonized international standards. Meanwhile, innovations in AI‐assisted farming, CRISPR‐based breeding, and automated processing are rapidly enhancing production efficiency, though further investment and validation are required. This review provides an overview of the nutritional, environmental, economic, technological, and safety dimensions of insects as food and feed. It also explores consumer perceptions and policy frameworks shaping adoption trends worldwide. By bridging current knowledge gaps and scaling inclusive innovation, edible insects hold immense promise for building resilient, ethical, and climate‐smart food systems for the future.

The abuse and misuse of antibiotics is one of the main drivers of antimicrobial resistance (AMR). Globally, AMR in food-producing animals is a significant public health concern. This study, therefore, assessed the knowledge, attitudes, and practices related to antibiotic usage (AMU) and AMR among poultry farmers in Nepal. We conducted a cross-sectional survey of 605 poultry farmers from six districts of Nepal from May to June 2022 to assess the status of knowledge, attitude, as well as practices toward prudent antibiotic usage (AMU) and AMR. The majority of the participants in our study were from the Chitwan district (31.6%; n = 191/605), aged 30–44 (54.2%; n = 328/605), males (70.4%; n = 426/605), and farmers with a higher secondary (28.76%; n = 174/605) level of education. The tetracyclines (28%, n = 228/828), aminoglycosides (23%, n = 188/828), and fluoroquinolones (15%, n = 126/828) were the most used antibiotics classes among poultry farmers. Although 87.8% (n = 531/605) of poultry farmers used antibiotics, 49.8% (n = 301/605) of them were aware of AMR, and 55.7% (n = 337/605) knew that the misuse of antimicrobials could affect human and environmental health. There were significant differences in the knowledge, attitude, and practices toward prudent AMU and AMR among farmers who reared different birds. The mean knowledge, attitude, and practice score of the respondents were 7.81 ± 3.26, 5.8 ± 2.32, and 7.59 ± 3.38 when measured on a scale of 12, 10, and 15, respectively. Based on a cut-off of 75% of the maximum score, 49.4% (n = 299/605), 62.8% (n = 380/605), and 12.73% (n = 77/605) of the respondents had good knowledge, attitude, and practices toward prudent AMU and AMR, respectively. The multivariable logistic regression analyses revealed that the positive predictors of good knowledge and attitude were male gender, higher level of education, district, and the types of birds (layers). Similarly, those of the male gender (OR: 3.36; 95% CI: 1.38–8.20; p = 0.008) and those that rear layers (OR: 4.63; 95% CI: 1.75–12.25; p = 0.003) were more likely to practice prudent usage of antimicrobials. The findings of this study show poor practice toward prudent antibiotic usage despite good knowledge of AMR. This study provides essential baseline data on the knowledge, attitudes, and practices of poultry farmers in Nepal and offers valuable insights that could help in the design of interventions and policies aimed at addressing illicit AMU and AMR in poultry in Nepal.

Background and Aim: One Health (OH) is a collaborative, multisectoral, and holistic approach for the prevention and control of emerging and re-emerging zoonotic diseases affecting animals and humans. In Nepal, the OH concept remains rudimentary. However, the recently formed "One Health Strategy" is a ray of hope. Veterinary students are the future of animal health, a major component of OH. This study aimed to determine the knowledge and perception of Nepalese veterinary students toward OH. Materials and Methods: A cross-sectional questionnaire survey was conducted among veterinary students in all four veterinary colleges in Nepal to obtain knowledge on OH and zoonotic disease and understand the perception of the benefits of OH obtained using an online survey tool through a convenience sampling technique. Data collected were subjected to descriptive statistics, Chi-Square test, and logistic regression analysis. Results: A total of 333 participants, including recent graduates (mean age: 22.3±2.2 years) participated in this study. The mean knowledge score was 19.8±3.8 and about half of the respondents, 185 (55.6%) demonstrated satisfactory scores on OH. Most of the respondents have a positive perception of the benefits of OH as participants largely agreed that the OH approach needs to become a regular, routine, and institutionalized process at the project, program, and policy levels; is useful in addressing complex challenges that threaten human and animal health, food security, poverty, and the environments where diseases flourish; and it creates added value in terms of human and animal health, financial savings or social and environmental benefits from closer professional cooperation. Binary logistic regression analysis revealed that age, educational, and academic levels were significant factors influencing satisfactory knowledge on OH among respondents. Conclusion: Nepalese veterinary students demonstrated satisfactory knowledge of OH and a good level of perception of the benefits of OH. An apprehensive understanding of the current status of the OH approach in Nepal through studies like this is crucial for the future improvement of public and animal health.

Vaccination is the most effective preventive measure of COVID-19 available at present, but its success depends on the global accessibility of vaccines and the willingness of people to be vaccinated. As the vaccination rollouts are increasing worldwide, it is important to assess public perception and willingness towards vaccination, so that the aim of mass vaccination will be successful. This study aimed to understand public perception towards COVID-19 vaccines and their willingness to get vaccinated in Nepal. This cross-sectional online survey was conducted among 1196 residents of Nepal in August 2021; most of the participants of this online survey were young adults (18–47 years) with university-level education. A total of 64.5% (771/1196) of the participants perceived COVID-19 vaccines to be safe and risk-free, while 68.6% (820/1196) agreed that vaccination would be efficient in the fight against this pandemic. Most of the participants (841/1196, 70.3%) disagreed that people are getting COVID-19 vaccines easily in Nepal, while they agree with the prioritization of older adults and healthcare workers for vaccination. A total of 61.1% (731/1196) of the participants had received at least one dose of the vaccine. Among the unvaccinated, 93.3% (434/465) were willing to get vaccinated when their turn came. The higher confidence of younger adults in vaccines and the vaccination process is encouraging, as that can help educate others who are hesitant or are not positive towards the idea of receiving vaccines. Dissemination of correct and current information, acquisition of enough doses of vaccines, and equitable distribution of vaccines will be required to achieve successful completion of the COVID-19 vaccination campaign in Nepal.

World Organization for Animal Health (OIE) has estimated that 60% of infectious diseases and 75% of emerging and re-emerging diseases of humans have an animal origin. In Nepal there six zoonoses; Taeniasis/cysticercosis /Neurocysticercosis, Leptospirosis, Hydatidosis, Brucellosis; Toxoplasmosis and Avian Influenza are identified as priorities zoonotic diseases as they are found to have epidemic potential. Although they are prioritised, there is high prevalence of these diseases in both humans and animals with insufficient research and data. Coordination of multiple stakeholders of public and animal health and One Health collaboration are crucial to control and elimination zoonotic diseases in Nepal. Int. J. Appl. Sci. Biotechnol.

Escherichia coli in untreated milk leads to economic losses from subclinical mastitis and reduced milk production, while also posing a public health risk due to the emergence of antimicrobial resistant strains, particularly associated with consuming unpasteurized milk and dairy products. This study aimed to determine the prevalence and antimicrobial resistance (AMR) of E. coli isolated from buffalo milk in Siddarthanagar Municipality of Rupandehi district, Nepal. A total of 102 milk samples were collected from lactating buffaloes. The isolation and identification of E. coli were carried out using enrichment media, selective media, and biochemical tests. Antimicrobial susceptibility testing was carried out using the Kirby–Bauer disk diffusion method on Mueller–Hinton agar (Merck), according to the Clinical and Laboratory Standards Institute (CLSI) recommendations. Resistance was tested against gentamicin, amikacin, ciprofloxacin, enrofloxacin, ceftriaxone, ceftazidime, cotrimoxazole, and chloramphenicol. In addition to this, farmers were administered a questionnaire consisting of both open- and close-ended questions to identify various animal-related and management-related risk factors associated with the prevalence of E. coli. The prevalence of E. coli in our study was 29.4% (n = 30/102). Ceftriaxone and ceftazidime showed 100% resistance, while cotrimoxazole and amikacin showed 86.7% and 80% resistance, respectively. Furthermore, 86.7% of E. coli isolates were multidrug resistant (MDR). Despite suggestive trends, associations between E. coli prevalence and risk factors lacked statistical significance, necessitating further research. While some antibiotics exhibited effectiveness, many faced resistance, highlighting the need for prudent antimicrobial usage and increased awareness among farmers. Raising awareness about milk pasteurization and implementing food safety practices is essential for ensuring farmers and public health.
