“…This is mainly because the situation is rapidly evolving on COVID-19, particularly on viral contamination of foods and associated risks of SARS-CoV-2 transmission, which have only started attracting public and regulatory concerns after the recent events. Most of the evidence on SARS-CoV-2 detection on frozen foods appeared between July-August 2020, weeks or months later after the recent 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).…”

The coronavirus disease 2019 (COVID-19) has brought speculations on possible transmission routes of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causal agent of the pandemic. Air pollution has been linked to increased risks of COVID-19 infection and mortality rates in regions with poor air quality, yet no retrospective study has been reported on foodborne transmission of COVID-19. While studies have shown that low temperature could dramatically prolong the persistence on SARS-CoV-2 and other coronaviruses, frozen and refrigerated foods have been widely overlooked as potential vectors in policy frameworks and risk mitigation strategies. Food transmission evidence has been disclosed in China early July 2020 by the detection of SARS-CoV-2 on frozen foods, including their packaging materials and storage environments, with two re-emergent outbreaks linked to contaminated food sources. The contamination risk is augmented by a complex farm-to-table process, which favors exposure to food workers and ambient environments. Moreover, the food cold-chain also promotes contamination because laboratory studies showed that SARS-CoV-2 remained highly stable under refrigerated, at 4 °C, and freezing conditions, from − 10 to − 80 °C, on fish, meat, poultry, and swine skin, during 14-21 days. While data are lacking on long-term survival and infectivity under these conditions, ample evidence has been shown on other coronaviruses, including SARS-CoV-1. We therefore hypothesize that contaminated cold-storage foods may present a systematic risk for SARS-CoV-2 transmission between countries and regions. Here, we review the evidence, risk factors, current policy and knowledge gaps, on food contamination and foodborne transmission of SARS-CoV-2.

“…Coronaviruses including SARs-CoV-2 are known to be susceptible to and easily inactivated by certain biocidal agents such as chlorine and its derivate and ethanol ( Quevedo-León et al, 2020 ). Zuber and Brüssow (2020) indicated that surface disinfection to inactivate human and animal coronaviruses can be achieved with 62–71% ethanol, 0.5% hydrogen peroxide, or 0.1% sodium hypochlorite within 1 min. Table 2 reports various chemical disinfectants against coronaviruses.…”

“…Businesses like Food Industries are getting impacted to maintain proper supply chain as many of the workers are falling sick to SARS-CoV-2. In order to create safe food environment, this companies are applying antimicrobial coatings to high touch surfaces like doors, handles, touch screen to inactivate the virus [27]. Similarly, Employees working in the retail sectors like shopping malls, Grocery stores who has direct customer exposure are 5 times more likely to have tested positive for SARS-CoV-2 [28].…”

Ongoing COVID-19 Pandemic has resulted into massive damage to various platforms of global economy which has caused disruption to human livelihood. Natural Language Processing has been extensively used in different organizations to categorize sentiments, perform recommendation, summarizing information and topic modelling. This research aims to understand the non-medical impact of COVID-19 on global economy by leveraging the natural language processing methodology. This methodology comprises of text classification which includes topic modelling on unstructured COVID-19 media articles dataset provided by Anacode. Like other Natural Language Processing algorithms, Latent Dirichlet allocation (LDA) and Non-negative matrix factorization (NMF) has been proposed to classify the media articles dataset in order to analyze COVID-19 pandemic impacts in the different sectors of global economy. Model Accuracy was examined based on the coherence and perplexity score which came out to be 0.51 and -10.90 using LDA algorithm. Both the LDA and NMF algorithm identified similar prevalent topics that was impacted by COVID-19 pandemic in multiple sectors of economy. Through intertopic distance map visualization produced by LDA algorithm, it can be reciprocated that general industries which includes children schooling, parental care, and family gatherings had the major impact followed by business sector and the financial industry.
