[PMID: 39170381 PMCID: PMC11336433 DOI: 10.1016/j.heliyon.2024.e35154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Revised: 07/22/2024] [Accepted: 07/23/2024] [Indexed: 08/23/2024] Open
Abstract
The COVID-19 pandemic poses ongoing challenges to the sustainability of various socioeconomic sectors, including agriculture, the food supply chain, the food business, and environmental sustainability. This study employs data obtained from the World Health Organization (WHO), and Food and Agriculture Organization (FAO), as well as scientific and technical research publications, to evaluate the impacts of COVID-19 on agriculture and food security. This article seeks to highlight the profound influence of the COVID-19 pandemic on agriculture, the supply and demand of food, and the overall safety of food. The article also explores the several pathways by which COVID-19 can be transmitted in these areas and the various technologies employed for its detection. The ongoing and post-pandemic ramifications are substantial since they could decrease agricultural output due to limitations on migration, a downturn in international trade, less buying capacity, and disturbances in food production and processing. Therefore, based on this thorough investigation, recommendations are issued for mitigating and controlling the pandemic's effects.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 853:158676.

Abstract
Excessive residues of semicarbazide (SEM) can accumulate in animals after the original drug has been abused, posing a risk to human health. Herein, based on multifunctional silica-initiated dual mode signal response, a novel competitive-type immunosensor was constructed for ultrasensitive detection of SEM. As a preliminary signal amplification platform for immunosensors, polyethyleneimine reduced graphene oxide composite gold nanorods (PEI-rGO/AuNRs) modified gold electrodes (AuE) provide a high specific surface area and high electrical conductivity. The thionine-aminated silica nanospheres-AuPt (thi-SiO2@AuPt) were synthesized by a racile coprecipitation method for enzyme immobilization and redox species loading. The multifunctional silica nanosphere conjugated with labeling antibodies (Ab2) was employed as an immunoprobe. The per unit concentration target of SEM can be determined by differential pulse voltammetry (DPV) to detect the thi loaded on the immunoprobe, which can also be determined by square wave voltammetry (SWV) to detect the current generated by the reaction system of H2O2 and hydroquinone (HQ) catalyzed by the immunoprobe with peroxidase. Under optimal conditions, the proposed immunosensor displayed a wide linear range from 1 μg-0.01 ng/mL and low detection limits (S/N = 3) of 0.488 pg/mL and 0.0157 ng/mL, respectively. Ultimately, the developed method exhibits excellent performance in practical applications, providing promising probabilities for SEM detection.

Abstract
Introduction Porcine circovirus type 2 (PCV2) causes immune repression and intercurrent infections in pigs, resulting in a huge economic loss to the pig breeding industry. Additionally, the spread of PCV2 in pig farms can pollute the living environment of the residents in the farm’s vicinity, which increases the rate of infections. Therefore, rapid and sensitive detection methods are needed for disease prevention and timely environmental cleaning. Methods This research describes a highly sensitive sandwich enzyme-linked immunosorbent assay (ELISA) that utilizes gold nanoparticles (AuNPs) in a functional, specific antibody labeled probe for the detection of PCV2. Due to their high specific surface area and histocompatibility, AuNPs were used as carriers of HRP labeled anti-PCV2 antibodies to amplify the detection signal. Results Compared to conventional sandwich ELISA procedures, this method resulted in higher sensitivity (51-fold) and a shorter assay time with a limit of detection of 195 TCID50/mL. The cross-reactivity assay demonstrated that this assay was PCV2 specific. Conclusion The amplified Ab (HRP) labeled AuNPs probe provides a sensitive analytical approach for the determination of the traces of the PCV2 antigen in early diagnosis.

Abstract
The foremost challenge in countering infectious diseases is the shortage of effective therapeutics. The emergence of coronavirus disease (COVID-19) outbreak has posed a great menace to the public health system globally, prompting unprecedented endeavors to contain the virus. Many countries have organized research programs for therapeutics and management development. However, the longstanding process has forced authorities to implement widespread infrastructures for detailed prognostic and diagnostics study of severe acute respiratory syndrome (SARS CoV-2). This review discussed nearly all the globally developed diagnostic methodologies reported for SARS CoV-2 detection. We have highlighted in detail the approaches for evaluating COVID-19 biomarkers along with the most employed nucleic acid- and protein-based detection methodologies and the causes of their severe downfall and rejection. As the variable variants of SARS CoV-2 came into the picture, we captured the breadth of newly integrated digital sensing prototypes comprised of plasmonic and field-effect transistor-based sensors along with commercially available food and drug administration (FDA) approved detection kits. However, more efforts are required to exploit the available resources to manufacture cheap and robust diagnostic methodologies. Likewise, the visualization and characterization tools along with the current challenges associated with waste-water surveillance, food security, contact tracing, and their role during this intense period of the pandemic have also been discussed. We expect that the integrated data will be supportive and aid in the evaluation of sensing technologies not only in current but also future pandemics.

Abstract
Nanotechnology has gained prominence over the recent years in multiple research and application fields, including infectious diseases in healthcare, agriculture, and veterinary science. It remains an attractive and viable option for preventing, diagnosing, and treating diseases in animals and humans. The apparent efficiency of nanomaterials is due to their unique physicochemical properties and biocompatibility. With the persistence of pathogens and toxins in the poultry and livestock industries, rapid diagnostic tools are of utmost importance. Though there are many promising nanomaterials-based diagnostic tests specific to animal disease-causing agents, many have not achieved balanced sensitivity, specificity, reproducibility, and cost-effectiveness. This mini-review explores several types of nanomaterials, which provided enhancement on the sensitivity and specificity of recently reported diagnostic tools related to animal diseases. Recommendations are also provided to facilitate more targeted animal populations into the development of future diagnostic tools specifically for emerging and re-emerging animal diseases posing zoonotic risks.

Abstract
The COVID-19 pandemic has hit hard on the world economy and global health. Where most businesses are completely closed following governments restrictions, the food sector across the supply chain must remain operational in order to feed the nations. In such a challenging time, keeping the workers healthy and safe is critical while maintaining a high level of food safety and consumer confidence. Against a backdrop of heightened uncertainty, up-to-date and reliable information is more important than ever, both for regulators and this sector. This literature review aims at assembling all current knowledge about COVID-19 and its impact on the food industry. It is an exhaustive compilation of relevant public information and guidance published by the World Health Organization (WHO), and collected from 11 governmental and 10 non-governmental sources as well as 25 peer-reviewed articles published in scientific journals since the beginning of the crisis till June 5th, 2020. This paper could be of assistance to educators, researchers, and policy makers. It could also serve as an assessment tool to ensure business continuity and to determine the level of food industry readiness providing reassurance to all stakeholders during these unprecedented times.

Abstract
It is a great challenge to develop a newly rapid and accurate detection method for pesticide residues. In this work, based on acetylcholinesterase (AChE) and choline oxidase (CHO), a double-enzymes-mediated Fe2+/Fe3+ conversion as magnetic relaxation switch was explored for the measurement of acetamiprid residue. In the double-enzymes reactions, acetylcholine chloride (ACh) can be catalyzed to produce choline by AChE, which is successively hydrolyzed to betaine and hydrogen peroxide (H2O2) by CHO. According to the enzyme inhibition principle, AChE activity will be inactivated in the presence of acetamiprid, thus leading to the less production of H2O2. Wherein, Fe2+, ACh, AChE and CHO were optimized as the reaction substrates. In the reaction system, acetamiprid can be reflected by the transverse relaxation time (T2) that related with H2O2 mediated Fe2+ variations, which was further developed as an enzyme cascade amplification method. The detection linear range is 0.01∼1000 μg mL-1 (R2 = 0.99), and the limit of detection (LOD) is 2.66 ng mL-1 (S/N = 3, n = 3), behaving a 335-fold improvement in LOD than that of traditional enzyme inhibition method (0.89 μg mL-1). This method can realize "one-step mixing" detection of acetamiprid, which makes it a promising analytical tool for monitoring pesticide residue in complicated samples.

Abstract
Exposure to pathogenic microorganisms, especially viruses, can lead to various diseases, allergies, and hospital infections. The application of sampling procedure is still a challenge to sample viruses from different environments such as air, water, wastewater, etc. However, there are many procedures such as filtration, impactor, impinger, cyclone, electrostatic separator, and MD-8 airscan that are applied for sampling and measuring viruses from air. Among conventional filters, the gelatin type can be readily dissolved in a liquid for molecular counting or cell culture without significant changes in virus tissue. Liquid impingers are the most frequent devices that are applied for the collection of viral aerosols. Also, many methods including precipitation, ultracentrifugation, electronegative membrane, and ultrafiltration have been used to prepare samples of food, wastewater, feces, urine, and surfaces. In many studies, the aforementioned methods have been employed to sample the coronaviruses such as SARS-CoV-2 in various environments. Also, various PCR procedures have been commonly used to identify the virus from the environmental samples.

Abstract
Traditional enzyme-linked immunosorbent assay (ELISA) suffers from the limitations of relatively low sensitivity and stability, and enzyme-labelled antibodies are hard to be prepared and purified. Based on a nanozyme, an aptamer and Fe3O4 magnetic nanoparticles (MNP), a nanozyme and aptamer-based immunosorbent assay (NAISA) was developed for aflatoxin B1 (AFB1) detection with simpler operation and separation. In this work, mesoporous SiO2/Au-Pt (m-SAP) were prepared to act as signal labels, which showed high catalase-like activity and was denoted as nanozyme. Aptamer was adopted to specifically recognize with AFB1, and MNP facilitated to realize magnetic separation. To verify the performance of NAISA, traditional ELISA (t-ELISA) and enhanced ELISA (e-ELISA) using MNP and m-SAP nanozyme were applied in AFB1 detection. The NAISA method showed the lowest limit of detection (LOD) with 5 pg mL-1 (n = 3, ±4.2 %), 600 and 12-fold lower than that of t-ELISA (3 ng mL-1) and e-ELISA (0.06 ng mL-1), respectively. In the interference tests, AFB1 can be identified among six different interfering substances. The NAISA method, thus, can be of great importance as it allows selective and sensitive AFB1 detection, while providing the simplicity of use and need for screening hazardous materials.

Abstract
BACKGROUND The COVID-19 pandemic has generated a new era in the world while we still figure out the consequences in different aspects of our daily life. The food supply chain and the food industry do not comprise an exception. SCOPE AND APPROACH This review summarizes the possible transmission ways of COVID-19 through the foods, food supply chain, surfaces, and environment before exploring the development of corresponding detection tools of SARS-CoV-2. For the time being, the possibility of transmission through the food sector is considered negligible, and tracing of SARS-CoV-2 in working environments is not considered as a priority by public authorities. However, the adverse effects on the environment, food systems, and people along the food supply chain are already evident. KEY FINDINGS AND CONCLUSIONS As long as we move from farm to fork, more safety measures are needed since more people (and subsequently more potential sources of infection) are involved in the process. The need for developing respective bioanalytical protocols for food and environmental safety applications to adapt in the post-lockdown period is also highlighted.

Abstract
The excessive use and ingestion of residues of sulfonamides harm the human body and the environment. To meet the requirements of the maximum residue limit specified by the Ministry of Agriculture of China, a rapid detection method urgently needs to be developed. In the present study, a molecularly imprinted polymer (MIP) that could selectively recognize sulfadiazine (SDZ) was prepared using SDZ as the template molecule and methacrylic acid as the functional monomer. Using MIP as biomimetic antibody and Au@Pt@SiO2 nanozyme as a marker, a new biomimetic immunoassay was developed to detect sulfadiazine. Under the optimal conditions, the limit of detection (IC15) and sensitivity (IC50) of this method were 0.09 and 6.1 mg/L, respectively. To determine the accuracy of this method, honey and milk samples spiked with sulfadiazine were analyzed, with recoveries in the range of 70.8%-90.2%. The method was also used for the quantitative analysis of sulfadiazine residues in milk powder and milk samples, producing results which correlated well with those obtained by high-performance liquid chromatography.

Abstract
BACKGROUND As a promising candidate for artificial enzymes, catalytically active nanomaterials show several advantages over natural enzymes, such as controlled synthesis at low cost, tunability of catalytic activities, and high stability under stringent conditions. Rod-shaped Au-Pt core/shell nanoparticles (Au@Pt NRs), prepared by Au nanorod-mediated growth, exhibit peroxidase-like activities and could serve as an inexpensive replacement for horseradish peroxidase, with potential applications in various bio-detections. The determination of measles virus is accomplished by a capture-enzyme-linked immunosorbent assay (ELISA) using Au@Pt NR-antigen conjugates. RESULTS Based on the enhanced catalytic properties of this nanozyme probe, a linear response was observed up to 10 ng/mL measles IgM antibodies in human serum, which is 1000 times more sensitive than commercial ELISA. CONCLUSIONS Hence, these findings provide positive proof of concept for the potential of Au@Pt NR-antigen conjugates in the development of colorimetric biosensors that are simple, robust, and cost-effective.

Abstract
A sensitive Point-of-Care Testing (POCT) with Au-Pt bimetallic nanoparticles (Au@Pt) functionalized silica nanoparticle (SiO2 NPs) and Fe3O4 magnetic nanoparticles (Fe3O4 NPs) was designed for the quantitative detection of Escherichia coli O157:H7 (E. coli O157:H7). The poly-(4-styrenesulfonic acid-co-maleic acid) (PSSMA) as a negatively charged polyelectrolyte can be easily coated on surface of the amino group modified SiO2 NPs via electrostatic force. PSSMA is also a good stabilizer for water-soluble bimetallic nanostructures. The PSSMA is first time used as a "bridge" to connect the negative charge Au@Pt NPs to the SiO2 NPs, forming Au@Pt/SiO2 NPs. Antibody and invertase conjugated Au@Pt/SiO2 NPs (denoted as Ab/invertase-Au@Pt/SiO2 NPs) were used as signal labels. Monoclonal antibody against E. coli O157:H7 (Ab) functionalized magnetic nanoparticles (denoted as Ab-Fe3O4@SiO2 NPs) were used to enrich and capture the E. coli O157:H7 in positive sample. The immunosensing platform also composed of a personal glucometer (PGM) using for signal readout. Based on this sandwich-type immunoassay, the invertase in the final formed sandwich immunocomplex catalyzed the hydrolysis of sucrose to produce a large amount of glucose for quantitative readout by the PGM. Under optimal conditions, a linear relationship between the glucose concentration and the logarithm of E. coli O157:H7 concentration was obtained in the concentration range from 3.5 × 102 to 3.5 × 108 CFU mL-1 with a detection limit of 1.83 × 102 CFU mL-1 (3σ). This method was used to detect E. coli O157:H7 in spiked milk samples, indicating its potential practical application. This protocol can be applied in various fields of study.

Abstract
A new electrochemical method has been proposed for the simultaneous determination of butylated hydroxyanisole (BHA) and propyl gallate (PG) in food matrices based on enzymatic biosensors. Spiny Au-Pt nanotubes (SAP NTs) was first synthesized and demonstrated to exhibit intrinsic peroxidase and catalase-like activity. The structure of SAP NTs provides large surface area and favorable medium for electron transfer, on which HRP were immobilized and acted as enzymatic biosensor for the simultaneous detection of BHA and PG. The results revealed that BHA and PG both have well-defined oxidation waves with peak potentials of 624 and 655 mV, respectively. Under the optimal conditions, the method behaved satisfactory analytical performance towards BHA and PG with a wide linear range of 0.3-50 mg L(-1) and 0.1-100 mg L(-1), as well as a detection limit of 0.046 mg L(-1) and 0.024 mg L(-1) (3σ/slope), respectively. Besides, the proposed method exhibits good sensitivity, stability and reproducibility, providing an alternative to fabricate electrode and construct sensitive biosensors.
