Is it Gastro or Food Poisoning?
Gastro or ‘gastroenteritis’ isn’t always caused by eating contaminated food. It can be caused by a viral infection. Symptoms may be similar and include diarrhoea, but whereas food poisoning symptoms usually begin 2 to 6 hours after eating contaminated food, with viral gastroenteritis, symptoms generally start 24 to 48 hours after exposure to the virus.
