The food safety security (FSS) concept is perceived as an early warning system for minimizing food safety (FS) breaches, and it functions in conjunction with existing FS measures. Essentially, the function of FS and FSS measures can be visualized in two parts: (i) the FS preventive measures as actions taken at the stem level, and (ii) the FSS interventions as actions taken at the root level, to enhance the impact of the implemented safety steps. In practice, along with FS, FSS also draws its support from (i) legislative directives and regulatory measures for enforcing verifiable, timely, and effective compliance; (ii) measurement systems in place for sustained quality assurance; and (iii) shared responsibility to ensure cohesion among all the stakeholders namely, policy makers, regulators, food producers, processors and distributors, and consumers. However, the functional framework of FSS differs from that of FS by way of: (i) retooling the vulnerable segments of the preventive features of existing FS measures; (ii) fine-tuning response systems to efficiently preempt the FS breaches; (iii) building a long-term nutrient and toxicant surveillance network based on validated measurement systems functioning in real time; (iv) focusing on crisp, clear, and correct communication that resonates among all the stakeholders; and (v) developing inter-disciplinary human resources to meet ever-increasing FS challenges. Important determinants of FSS include: (i) strengthening international dialogue for refining regulatory reforms and addressing emerging risks; (ii) developing innovative and strategic action points for intervention {in addition to Hazard Analysis and Critical Control Points (HACCP) procedures]; and (iii) introducing additional science-based tools such as metrology-based measurement systems.

UNSTRUCTURED The HIV epidemic imposes a heavy burden on societal development. Presently, the protection of susceptible populations is the most feasible method for eliminating the spread of HIV. Governments and other relevant industries are actively attempting to solve the problem. In view of the unavailability of biological vaccines, the best measures that can currently be applied are identification of HIV-infected persons and provision of treatment and behavioral intervention. This paper proposes a HIV digital vaccine strategy based on blockchain technology. In the proposed strategy, a decentralized surveillance network is jointly constructed using HIV high-risk individuals as application nodes and accredited testing agencies as authentication nodes. Following testing at the authentication nodes, the results are uploaded to the blockchain, which results in HIV high-risk individuals being able to determine the HIV infection status of each other in a convenient, anonymous, and credible manner. This reduces the occurrence of high-risk sexual behavior and effectively protects susceptible populations. The proposed strategy is a promising solution to prevent the spread of HIV. The performance of the decentralized surveillance network may lead to the restructuring of current government-funded infectious disease prevention and control modes that are centered on centers for disease control and prevention and hospitals to introduce revolutionary changes in public health systems globally.
