What is Coronavirus?
Coronaviruses are a large family of viruses that usually cause respiratory illness. They include viruses that cause the common cold and seasonal flu, as well as more serious illnesses like Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).
COVID-19 is a new strain that has not previously been identified in humans and was first identified in Wuhan, Hubei Province, China.
What are the symptoms?
Signs of infection include high fever (>38ºC) together with one or more respiratory symptoms like coughing, shortness of breath and breathing difficulties.
Severe symptoms include pneumonia, severe acute respiratory syndrome and kidney failure.
Can the virus be passed on through food?
Experience with SARS and MERS suggest that people are not infected with the virus through food. So, it is unlikely the virus is passed on through food and there is no evidence yet of this happening with COVID-19 (coronavirus) to date.
Coronaviruses need a host (animal or human) to grow in and cannot grow in food. Thorough cooking is expected to kill the virus because we know that a heat treatment of at least 30min at 60ºC is effective with SARS.
How is COVID-19 (coronavirus) passed on?
Coronaviruses are most commonly passed between animals and people and from person to person. The source of COVID-19 (coronavirus) is believed to be animals, but the exact source is not yet known.
The virus is commonly passed on:
1.Directly, through contact with an infected person's body fluids (for example, droplets from coughing or sneezing)
2.Indirectly, through contact with surfaces that an infected person has coughed or sneezed on
Current information suggests that the virus may survive a few hours on surfaces. Simple household disinfectants can kill it.
Investigations in China are continuing to identify the source of the outbreak and ways it can be passed on to people.
What can food workers do?
It is possible that infected food workers could introduce virus to the food they are working on by coughing and sneezing, or through hand contact, unless they strictly follow good personal hygiene practices.
The World Health Organisation (WHO) advises that standard recommendations to reduce exposure to and transmission of a range of illnesses are maintained. These include:
proper hand hygiene
cough/cold hygiene practices
safe food practices
avoiding close contact, when possible, with anyone showing symptoms of respiratory illness such as coughing and sneezing
Food workers must wash hands:
before starting work
before handling cooked or ready-to-eat food
after handling or preparing raw food
after handling waste
after cleaning duties
after using the toilet
after blowing nose, sneezing or coughing
after eating drinking or smoking
after handling money
Good hygiene and cleaning are also important to avoid cross contamination between raw or undercooked foods and cooked or ready to eat foods in the kitchen.
