Abstract
Humanity is currently facing a life-threatening challenge from the infectious and epidemic disease SARS-CoV-2. To date, the various modes of transmission of the virus have not been fully elucidated. In this regard, there is a possibility of transmission of the virus through food products. The COVID-19 pandemic disease, like those associated with SARS and MERS, is transmitted mainly through the respiratory tract and airborne aerosol particles, but the presence of fragments of the genetic virus (RNA) in the feces of numerous patients proposes that their fecal-oral pathway may be expanded. In addition, people with gastrointestinal disorders such as atrophic gastritis and metaplasia may be susceptible to COVID-19 infection. Accordingly, food may act as a potential carrier of COVID-19 due to environmental or cross-contamination. According to the available evidence, the spread and possibility of transmission of COVID-19 contamination from humans to food products are possible. Beyond that, there is some evidence that some food sources of animal origin, such as pigs and rabbits, can be contaminated by COVID-19. Therefore, the transmission of the virus through some meat products may be conceivable. Due to the rapid release rate of COVID-19 and its stability in various milieus, especially food manufacturing circumstances, it may enter the matrix during different stages of traditional or industrial food processing. Therefore, preventive measures are recommended to be utilized in the food manufacturing sector. The present study explored the risk of different food matrices, including dairy products, bread, meat and meat products, vegetables, fruits, and processed foods, as potential carriers for the transmission of COVID-19.
