Abstract The emergence of severe acute respiratory syndrome (SARS), Nipah virus and H5N1 has sparked fears of food-borne dissemination of viruses, resulting in an increased focus on microbiological food safety. Norovirus (NoV) and hepatitis A virus (HAV) have been recognized as priorities based on their illness burden, and as models for prevention studies. In addition, hepatitis E virus is considered an emerging food-borne pathogen. Systematic surveillance for food-borne viral diseases, where present, has to deal with underreporting, with available data biased towards developed countries, making true estimates of the burden of illness challenging. Nevertheless, food-borne viral outbreaks are often reported, whereas current measures undertaken by food safety management organizations are focused primarily on bacterial contamination and are insufficient for viruses in food. There has been a shift towards molecular techniques for the diagnosis and detection of viruses in food, but a definite link to food is still hard to establish owing to the low levels of viruses in foods. Moreover, multiple strains may be involved in sewage-contaminated foods, with the risk of recombination and development of novel strains after ingestion. To enable monitoring of food and food safety, sensitive routine methods are needed, and methods for detection of NoV and HAV in risk foods (shellfish, soft fruit and leafy greens) are currently validated. Norovirus cannot be cultured, but the murine NoV may be a surrogate for studying NoV survival. In all, significant progress has been made in understanding food-borne viral infections, but clear data gaps still exist and should be the focus of future research.

The SARS-CoV-2 pandemic had widespread and severe impacts on both the global economy and human health. Facing the continuously mutating virus, this crisis has heightened concerns among consumers and businesses regarding viral transmission through seafood, particularly in the face of emerging, unknown viruses, underscoring our preparedness gaps. This review provides a succinct overview of the survival mechanisms of prevalent viruses in seafood, examines potential transmission pathways to humans during seafood processing, and discusses strategies for mitigating their spread throughout the seafood supply chain. Furthermore, the discussion highlights emerging trends in innovative antiviral technologies aimed at enhancing food safety. Person-to-person transmission remains the most likely source of infection within the supply chain. Therefore, it is still imperative to adhere to the implementation of standard processes, namely good manufacturing practices (GMP) and good hygiene practices (GHP), in the seafood business. In light of the significant losses caused by this crisis and the persistent presence of various viruses within the seafood supply chain, efforts are needed to implement predictive and preventive measures against potential emerging viruses. Future research should focus on monitoring and limiting viral transmission by integrating Industry 4.0 applications, smart technologies, and antiviral packaging, maximizing the potential of these emerging solutions.

ent discussions on food-associated transmission of COVID-19 (Ceylan et al. 2020 ; Eslami and Jalili 2020 ; Rizou et al. 2020 ; Sharma et al. 2020 ; Zuber and Brüssow 2020 ). Further, studies on the stability of SARS-CoV-2 in food environments only began to appear in early July 2020 (Fisher et al. 2020 ; Harbourt et al. 2020 ). These critical developments called for an updated and more informed view on this matter, by reviewing new evidence, scholarly discussions, and current policy and knowledge gaps. In this article, we focus on cold-storage foods and their possible contamination by SARS-CoV-2 through the “farm-to-table” lifecycle, with an particular emphasis on the “cold chain” which plays a central role in the storage and distribution of foods in this category such as seafood, meat, fresh produce, and frozen food varieties. To this end, we present a critical assessment on the up-to-date evidence and information that are most relevant to the hypothesized routes of virus transmission via contaminated cold-storage foods, in the current COVID-19 context. The main points discussed are (1) risks of food contamination by SARS-CoV-2 through the “farm-to-table” lifecycle, including the “cold chain” (2) packaging materials and temperatures used for storing and transporting refrigerated and frozen foods through the “cold chain” (3) persistence of SARS-CoV-2 on food surfaces and in low-temperature environments, with references to other coronaviruses (4) risks and potential transmission routes of SARS-CoV-2 in the retailing environment (5) major gaps in current policies and knowledge to address food contamination and foodborne transmission as a risk factor during the current pandemic. We highlight these gaps to provide a point of reference for future studies and risk assessments on foodborne transmission of COVID-19 and other human respiratory pathogens during pandemics. Food contamination and the cold chain Cold-storage foods, including the refrigerated and frozen varieties,

Abstract Background The global community has battled the spread of SAR-CoV-2 for almost 2 years, and the projection is that the virus may be recurrent like the seasonal flu. The SARS-CoV-2 pandemic disrupted activities within the food supply chain that cost billions of dollars globally. This has heightened concerns about fomite spread of the virus through surfaces. There is an urgent need to understand the risk portends by this virus along the produce supply chain with conditions (low temperature and high relative humidity) conducive to extended survival of the virus. Main body Pre-dating SARS-CoV-2 are other types of coronaviruses that had lower infection and mortality rates. There are some similarities between the former and the new coronavirus, especially with regards to transmission modes and their survivability on surfaces. There is evidence of other coronaviruses’ survival on surfaces for weeks. Currently, there are limited evidence-based studies to enlighten us on how the virus is transmitted within the produce supply chain. A few studies claim that the virus could spread through the cold supply chains. However, these are not sufficient to make a conclusive inference about the deadly SARS-CoV-2. Conclusions This paper provides a succinct review of the literature on current understanding of the transmission, survivability, and risk SARS-CoV-2 portend to humans within the produce supply chain and calls for more evidence-based research to allay or alert us of the potentia

Coronaviruses are a large family of viruses that, according to evidence, can cause diseases ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS) or even more severe diseases such as Severe Acute Respiratory Syndrome (SARS). Epidemiology A disease, whether contagious or non-contagious, may be more or less common in some areas and under some conditions among a large number of people. In other words, a disease can be more or less common. The science that studies how diseases spread and what causes them to spread is called epidemiology, which is a branch of medical science. Basically, epidemiology seeks to prevent the occurrence and spread of a disease or to control it if it does spread. Communicable diseases are a type of infectious disease that can be transmitted from person to person or to humans through insects and other animals. This disease can also be transmitted by organisms in contaminated water or food that has been exposed to the environment by an infected person. For example, a sick child's cough is one way to transmit a cold or flu to others, which must be well taken care of and prevented. In general, the factors that because infectious diseases include viruses, bacteria, and parasites. The signs and symptoms of infectious diseases will also vary depending on the agent causing the infection.
