Question: How can I keep my cafe safe from viral contamination?

Answer passage (source: WHO):
page_title: Q&A on coronaviruses (COVID-19)
section_headers: What can I do to protect myself and prevent the spread of disease?
section_content: Stay aware of the latest information on the COVID-19 outbreak, available on
the WHO website and through your national and local public health authority.
Most countries around the world have seen cases of COVID-19 and many are
experiencing outbreaks. Authorities in China and some other countries have
succeeded in slowing their outbreaks. However, the situation is unpredictable
so check regularly for the latest news.
You can reduce your chances of being infected or spreading COVID-19 by taking
some simple precautions:

Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water. Why? Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.
Maintain at least 1 metre distance between yourself and others. Why? When someone coughs, sneezes, or speaks they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person has the disease. 
Avoid going to crowded places. Why? Where people come together in crowds, you are more likely to come into close contact with someone that has COVID-19 and it is more difficult to maintain physical distance of 1 metre. 
Avoid touching eyes, nose and mouth. Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and infect you. 
Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately and wash your hands. Why? Droplets spread virus. By following good respiratory hygiene, you protect the people around you from viruses such as cold, flu and COVID-19. 
Stay home and self-isolate even with minor symptoms such as cough, headache, mild fever, until you recover. Have someone bring you supplies. If you need to leave your house, wear a mask to avoid infecting others. Why? Avoiding contact with others will protect them from possible COVID-19 and other viruses. 
If you have a fever, cough and difficulty breathing, seek medical attention, but call by telephone in advance if possible and follow the directions of your local health authority. Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections. 
Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities. Why? Local and national authorities are best placed to advise on what people in your area should be doing to protect themselves.

page_title: Questions relating to food businesses
section_headers: How should food premises be cleaned/disinfected during this pandemic?
section_content: The general guidelines outlined in the General Principles of Food
Hygiene
for food processing and manufacture premises should be followed. If a
suspected or confirmed case of COVID-19 is identified in a food premises then
there is a requirement to completely clean the area with a neutral detergent,
followed by decontamination of surfaces using a disinfectant effective against
viruses. All surfaces that the infected employee has come into contact with
must be cleaned, including all surfaces and objects which are visibly
contaminated with body fluids/respiratory secretions, and all potentially
contaminated high-contact areas such as toilets, door handles, telephones.
Alcohol based sanitizers/surface disinfectants should be used for cleaning
purposes. In general, alcohol-based disinfectants (ethanol, propan-2-ol,
propan-1-ol) have been shown to significantly reduce infectivity of enveloped
viruses like SARS-CoV-2, in concentrations of 70-80% with one-minute exposure
time. Chlorine-based disinfectants (sodium hypochlorite) are effective for
surface decontamination, as are disinfectants with active ingredients based on
quaternary ammonium compounds (QUATS).
All staff should wash their hands thoroughly for 20 seconds after any contact
with someone who is unwell with symptoms consistent with coronavirus
infection. Staff engaged in environmental cleaning should wear PPE when
performing cleaning activities, such as overalls or uniform, single-use
plastic aprons, gloves and a face mask. Protective clothing (e.g. uniforms,
overalls, etc.) should be frequently washed at 60°C or above.

The answer does talk about keeping food safe, but it is not in depth.  It is not really specific to cafes either.
This answer addresses the question but could give more detail.
