Food poisoning is rarely serious but there are some viruses that can result in an illness so severe some people end up in hospital needing treatment. Symptoms of food poisoning usually develop within a few days or hours of eating the food that caused the infection.
It is important to know the symptoms of food poisoning and when to seek help. It comes after Public Health Wales confirmed on Monday it was investigating a potential outbreak of the shigella virus in the Abergavenny area of Wales.
It said it had been alerted to an increase in cases of "gastrointestinal" illness in the area, which might have been caused by shigella infection. WalesOnline is aware of several people who have experienced sickness and diarrhoea after eating from a takeaway restaurant in Abergavenny on February 12.
