Abstract

The development of industry and technology, changes in agriculture, trade and global travel, and the adaptation of microorganisms are important factors in the occurrence of emerging diseases. Currently, the world is facing a pandemic caused by an emerging virus called the novel coronavirus (Covid 19) in 2020. This disease led to infect more than one million people worldwide and the death of more than five hundred thousand people during six months. Covid 19 causes death in patients with respiratory problems of varying severity. Fever, soreness, dry coughs, shortness of breath, runny nose, and nasal congestion were observed in coronavirus-infected individuals. Fever was one of its common symptoms. Other unusual signs such as diarrhea and nausea were reported for this disease. For the first time, the bat was introduced as the host of the novel coronavirus in China. Therefore, identifying the initial route of transmission of the novel coronavirus is necessary to prevent the occurrence and its widespread distribution. The virus enters into a human through respiratory particles as well as touching the surfaces contaminated by nasal, mouth and eye secretions. Viruses are obligate intracellular pathogens needing host cells to survive. These microorganisms cannot proliferate in foods and require live cells for existence. Food is introduced as a carrier of viruses to the consumer. There have been no reports of novel coronavirus transmission through food. However, it is important to observe the principles of health and safety by assuming the spread of the virus due to food contamination. Regarding the presence and proliferation of novel coronavirus in the gastrointestinal tract and aerosol formation of this microorganism in the feces and the possibility of retransmitting it to people from various environmental sources, the most important priority is to remove the virus from food environments. It is also important to update the methods of disinfecting surfaces, especially areas with high contact of hand as well as personal hygiene. Therefore, it is recommended to educate the staff about managing the novel coronavirus and improving health guidelines. Furthermore, keeping distance and washing hands is in priority in different food-related environments. © 2021 Tehran University of Medical Sciences. All rights reserved.
