In developing countries, such as Nepal, addressing food safety is particularly intricate and arduous because of the prevalent issues of food insecurity, poverty, illiteracy, and regulatory hurdles. The objectives of this comprehensive review are to evaluate the prevalent foodborne and waterborne illnesses, examine the existing regulations and institutional frameworks, and identify the challenges associated with food safety in Nepal. Additionally, this review aims to propose strategies to enhance food safety measures in the country. An electronic search was conducted using relevant keywords to include articles and literature pertinent to the topic. Common foodborne illnesses in Nepal include cholera, typhoid fever, hepatitis, worm infections, and poisoning from mushrooms, heavy metals, and pesticides. While existing rules, regulations, and government infrastructure exist, they often face limitations in effectively addressing these multifaceted challenges. Food safety in developing countries, such as Nepal, faces several challenges, including inadequate regulatory frameworks, limited surveillance and monitoring, rural–urban disparities, and high incidences of foodborne illness. Additional issues stem from weak law enforcement, poor food safety practices, limited infrastructure, informal sector challenges, cross-border trade, limited access to clean water, and the impacts of climate change.

Notably, there are significant differences in amino acid composition in sesame seeds at various developmental stages. However, the molecular basis and regulatory mechanism underlying amino acid production largely remain unexplored. To unravel these mechanisms, we analyzed the metabolome and transcriptome profiles of a sesame variety across four distinct growth stages (S1–S4). Our analysis identified a total of 17 amino acids, with glutamic acid (Glu), arginine (Arg), proline (Pro), and tyrosine (Tyr) exhibiting significantly higher abundances in mature stages. This increased abundance correlated with the elevated expression of genes involved in amino acid synthesis and regulatory genes. Using weighted gene co-expression network analysis, we discovered modules associated with glutathione metabolism, arginine biosynthesis, proline, and tyrosine synthesis, along with candidate genes that regulate amino acid production and metabolism. Notably, the differential expression of genes within the amino acid pathways resulted in significant variations in the contents of Glu, Arg, Pro, and Tyr at the mature stage (28 days after flowering, S4) compared to other growth stages. Correlation analysis revealed strong association among the enzymes glutamine synthetase (GS), glutamate/aspartate–prephenate aminotransferase (PAT), and polyamine oxidase (PAO) with the 17 amino acids, suggesting their potential role in the amino acid synthesis. Our findings provide novel insights into the synthesis and accumulation of amino acids during the growth stages of sesame seeds, highlighting key regulatory genes and metabolic pathways involved in this process.
