Symptoms of food poisoning (such as nausea, vomiting, abdominal cramping, and diarrhoea) may start suddenly (within 48 hours) of having contaminated food or drink, or may be as late as 70 days. These symptoms are affected by many factors including type of contaminant, the amount eaten, age and your overall health.
