Recently, PepsiCo reported that a worker in a Beijing factory had been  diagnosed of COVID-19, attracting a lot of public attention. Can we eat potato  chips now? What is the relationship between food and viruses? Feng Zijian,  deputy director of the Chinese Center for Disease Control and Prevention,  answered these questions. He said that a worker in the potato chips factory  infected with the coronavirus does not mean that the workers contaminated the  food. So far, no one has been infected by food, so it is not necessary to worry  too much about food safety. At room temperature, virus on dried food can only  live for a very short time, and will quickly lose activity. Viruses have been  detected in many places in the comprehensive trading hall of the Xinfadi market,  indicating that the virus has been more seriously spread in certain environment.  A number of confirmed cases have appeared at Xinfadi Market. The current  investigation and the preliminary findings indicate that it may be that the  human hand touched the surface of the contaminated body, and the contaminated  hand touched the mouth, eyes, nasal mucosa, etc., resulting in infection. This  method is called pollutant transmission in the epidemiology of infectious  diseases. The coronavirus will not be transmitted through food and beverage. It  is important to prevent the spread of interpersonal contact. Hand hygiene is  very important for coronavirus prevention. Therefore, good habits of washing  hands frequently, and minimize contact with dirty hands by mouth, nose, and eyes  are crucial.
