Symptoms usually develop between 2 and 72 hours after eating infected food. They usually include:
A person with food poisoning can pass the germs in their faeces for one to two weeks.
Most people can return to work or school 48 hours after the diarrhoea has stopped.
Food handlers, health care workers and children in day care must obtain the approval of the Regulation Department before returning to their occupation.
They want to find out what kind of food poisoning it is, how and where you might have caught it and to advise you about how to avoid passing it on to other people.
The EHO (Environmental Health Officer) may ask for details of:
|Bacteria||Where are the bacteria found?||How long after the food is eaten do symptoms appear?||How long does the illness last?|
