Updated questions and answers from the BfR on the transmission of the novel coronavirus via food and objects (as of 17.03.2020) - Part 2
On 20.03.2020 we informed you about the current publication of the BfR regarding the transmission of the novel coronavirus via food and objects.
In today's news, we would like to provide you with further information on this topic.
The transmission and spread of the coronavirus occurs primarily from person to person via droplet infection. It is unclear what role smear infections via door handles, tools, surfaces, or even food play.
The current publication of the BfR provides some answers to this, such as:
- As enveloped viruses, whose genetic material is surrounded by a fat layer (lipid layer), coronaviruses are sensitive to fat-dissolving substances such as alcohols or surfactants, which are contained as fat dissolvers in soaps and dishwashing detergents. Although there are not yet specific data for SARS-CoV-2, it is highly likely that these substances damage the virus surface and inactivate the virus. This is especially true when dishes are cleaned and dried in the dishwasher at 60 degrees Celsius or higher.
- In general, coronaviruses can be transferred directly onto door handles by sneezing or coughing of an infected person and survive for some time. A smear infection of another person then appears possible if the virus is transferred to the mucous membranes of the mouth and throat or the eyes shortly thereafter via hands. Therefore, good hand hygiene with regular handwashing and keeping hands away from the face is important.
- All common measures and rules of conduct to protect against noroviruses or influenza viruses in elderly care facilities also help against the transmission of SARS-CoV-2.
- The coronaviruses known so far, SARS and MERS, are cold-resistant and can remain infectious in a frozen state at minus 20 degrees Celsius for up to 2 years. However, there is currently no evidence of infection chains of SARS-CoV-2 through the consumption of food, including frozen food. The general hygiene rules for food preparation should be observed.
