However, infestations (pests including insects and rodents), microbial infections, and mycotoxin formation during the storage process result in a loss of about 10 % of total food grain production in India. This article explains various grain storage techniques, structures (short and long-term storage), traditional methods, and modern techniques' role in developing nations. Different grain storage issues, storage conditions, and physical, biological, and socio-economic factors have been explained. The toxic aflatoxins (AFs), which develop during grain storage and cause various health issues in livestock, are discussed. Advanced storage technologies for real-time monitoring of environmental parameters are summarized. The impact of chemical pesticide usage and the benefits of natural bio-pesticides in grain storage are presented. Natural plant species against major and minor insect pests are highlighted. A decision-making problem is implemented using the analytic hierarchy process (AHP) technique from the available plants in order to identify and use them for effective grain storage. This article provides insights to explore natural resources in the integration of technological interventions i.e. nanotechnology for the sustainable storage of grains. Ultimately, this is expected to enhance food security and human health.</div></div>","PeriodicalId":319,"journal":{"name":"Food Control","volume":"174 ","pages":"Article 111236"},"PeriodicalIF":5.6,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143478835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seasonal changes and higher temperatures elevated biological hazards among livestock. Produce contamination, notably in leafy green vegetables, increased with higher temperatures, precipitation, and flood events.

The critical need for precise and timely identification of MRSA in food matrices has become increasingly paramount for effective public health protection. While numerous CRISPR-based detection platforms for MRSA have been recently developed, their widespread implementation has been hindered by intricate multi-step protocols and dependency on sophisticated instrumentation. In this study, we developed a direct, accurate and visual detection method for MRSA — the RPA-Cas12a-LFS method. This method comprises two main components: (1) the direct one-pot RPA-Cas12a system, which integrates bacterial lysis, RPA nucleic acid amplification, and CRISPR-Cas12a nucleic acid detection into a single step performed simultaneously at a constant temperature, and (2) the streptavidin-gold nanoparticles (SA-AuNP)-based CRISPR-specific lateral flow strip (LFS). By eliminating the need for nucleic acid extraction, this method significantly simplifies the experimental procedure and reduces the risk of cross-contamination. Through systematic optimization, this method demonstrated exceptional performance, enabling direct and specific identification of MRSA at remarkably low concentrations (10 CFU/mL) within 60 min in various milk samples.
