Food & dairy safety are critical aspects of public health & consumer confidence. Various challenges & opportunities exist in ensuring the safety of these products throughout the supply chain. Challenges include microbial (emerging pathogens, virus, fungi), chemical (pesticide, antibiotic, heavy metals residues) contaminants & allergen mismanagement. The complexity of global supply chains & need for temperature maintenance can make it challenging to track & control potential hazards at different stages. Adhering to diverse & evolving food safety regulations across different regions, intentional adulteration, mislabelling & counterfeiting of food and dairy products can compromise safety and consumer trust. Rapid & sensitive testing methods, such as molecular diagnostics, enzyme mimetic nanomaterials or nanozymes, paper based colorimetric sensors, big data analytics, artificial intelligence can enhance traceability & predictive modelling, aiding in early detection of potential safety issues. Advanced technologies like blockchain and Internet of Things (IoT) devices can provide an transparent record of the entire supply chain and sensors can monitor factors like temperature & humidity in real-time. Harmonizing global food safety standards can simplify compliance for producers operating in multiple regions. Funding research into novel preservation techniques, safety interventions & pathogen mitigation strategies can drive continuous improvement.
