“…A number of smartphone-based devices or assays have already been developed for various contaminants, including marine toxins [ 28 , 46 , 47 ] and CTXs, in particular [ 48 ]. It should be noted that, currently, smartphones cannot be used on their own to detect food contaminants, without the contribution of some auxiliary part or hand-held device, such as portable electrochemical or optical sensors [ 28 , 47 , 48 , 49 ]. However, they possess independent power sources, computing power, flash-light cameras (i.e., optical systems with constant light sources), web access and wireless data communication, being powerful alternative analytical tools, able to radically change food testing.…”

Although smartphone apps for CTXs testing are not yet commercially available, the future ability of consumers to screen fish for CFP is expected to improve food security and increase public awareness, facilitating also risk assessment and management [ 47 , 49 ].…”

Currently, digital technologies influence information dissemination in all business sectors, with great emphasis put on exploitation strategies. Public administrations often use information systems and establish open data repositories, primarily supporting their operation but also serving as data providers, facilitating decision-making. As such, risk analysis in the public health sector, including food safety authorities, often relies on digital technologies and open data sources. Global food safety challenges include marine biotoxins (MBs), being contaminants whose mitigation largely depends on risk analysis. Ciguatera Fish Poisoning (CFP), in particular, is a MB-related seafood intoxication attributed to the consumption of fish species that are prone to accumulate ciguatoxins. Historically, CFP occurred endemically in tropical/subtropical areas, but has gradually emerged in temperate regions, including European waters, necessitating official policy adoption to manage the potential risks. Researchers and policy-makers highlight scientific data inadequacy, under-reporting of outbreaks and information source fragmentation as major obstacles in developing CFP mitigation strategies. Although digital technologies and open data sources provide exploitable scientific information for MB risk analysis, their utilization in counteracting CFP-related hazards has not been addressed to date. This work thus attempts to answer the question, “What is the current extent of digital technologies’ and open data sources’ utilization within risk analysis tasks in the MBs field, particularly on CFP?”, by conducting a systematic literature review of the available scientific and grey literature. Results indicate that the use of digital technologies and open data sources in CFP is not negligible. However, certain gaps are identified regarding discrepancies in terminology, source fragmentation and a redundancy and downplay of social media utilization, in turn constituting a future research agenda for this under-researched topic.

“…Marine biotoxin is a kind of highly active special metabolic component in marine organisms, which can severely affect human health, economy, wildlife, and ultimately the ecosystem ( Bano et al, 2020 ). By immobilizing BTX-2–bovine serum albumin conjugate on Au NP-decorated poly(amidoamine) dendrimers, Tang et al developed an electrochemical assay for the fast screening of brevetoxin B (BTX-2) in food samples ( Tang et al, 2011 ).…”

Nanozymes own striking merits, including high enzyme-mimicking activity, good stability, and low cost. Due to the powerful and distinguished functions, nanozymes exhibit widespread applications in the field of biosensing and immunoassay, attracting researchers in various fields to design and engineer nanozymes. Recently, nanozymes have been innovatively used to bridge nanotechnology with analytical techniques to achieve the high sensitivity, specificity, and reproducibility. However, the applications of nanozymes in food applications are seldom reviewed. In this review, we summarize several typical nanozymes and provide a comprehensive description of the history, principles, designs, and applications of nanozyme-based analytical techniques in food contaminants detection. Based on engineering and modification of nanozymes, the food contaminants are classified and then discussed in detail via discriminating the roles of nanozymes in various analytical methods, including fluorescence, colorimetric and electrochemical assay, surface-enhanced Raman scattering, magnetic relaxing sensing, and electrochemiluminescence. Further, representative examples of nanozymes-based methods are highlighted for contaminants analysis and inhibition. Finally, the current challenges and prospects of nanozymes are discussed.
