If there are cases of illness among staff or customers in your food premises, there could be an outbreak of viral gastroenteritis.
You must report this to us so we can help identify any potential outbreak and control it.
We also publish information on food poisoning and infectious diseases.

If you have two or more cases of diarrhoea or vomiting reported in the same week, occurring in either guests or members of staff, it is likely that there is an outbreak of viral gastroenteritis linked to the premises.
This may be the case if:
In these circumstances, contact us as soon as possible by calling 023 8028 5230 or by email to email@example.com.
We will advise you how to prevent further cases, and investigate the source and cause of the illness.
Confirmation can take a few days, as samples of food or faeces will need to be analysed in a laboratory.
While the investigation is being carried out, the following action should be taken by you to help prevent the spread of infection:
These may be appropriate to enable a full programme of environmental cleaning and disinfection to take place. In theory, a closure of 48 to 72 hours may be adequate, provided no more guests or staff are ill and a cleaning programme is undertaken as described.
It is not always possible to prevent an initial infection being brought into your business. However, it is possible to take reasonable precautions and show due diligence to avoid the risk of harm to customers.
The consequences to your business will be greater if you are unaware of the problem, delayed reporting it or did nothing to resolve it.
Outbreaks of viral gastroenteritis are commonly caused by norovirus, sometimes referred to as 'winter vomiting disease'. This illness is particularly common in situations where large numbers of people live or eat in proximity of each other, such as hotels and restaurants.
An outbreak of norovirus can be easily spread if no action plan is in place to ensure that adequate hygiene standards are maintained. It is possible, through prompt action, to control and avoid a single case becoming an outbreak situation.
Norovirus can be resistant to cleaning chemicals and may survive in the environment for several days, making it difficult to remove from items such as soft furnishing and carpets without steam cleaning.
Norovirus and other viruses causing gastroenteritis can be found in, but not limited to, the following sources.
Customers, members of staff or visitors may be unaware that they are infected. It is difficult to prevent a customers visiting your premises when poorly, but members of staff and contractors can be prevented from introducing an infection by having good infection control procedures in place.
Shellfish such as mussels, clams and oysters are live foods. These types of shellfish feed by filtering nutrients from the water, so are susceptible to contamination. Your business may control this by ensuring all shellfish are purchased from reputable suppliers, stored, prepared and handled correctly.
Watercress and other ready to eat salad type foods are also susceptible to contaminated water sources. Your business should ensure that these are purchased from reputable suppliers and handled and stored correctly.
