Salmonellosis causes most of the major outbreaks of bacterial food poisoning. Frequently, the victims are not sick enough to seek medical treatment from a doctor so are never reported. Campylobacter and viruses also cause a large number of food-borne infections in populations. Go to the CDC webpage to get specific information about food poisoning incidence. http://www.cdc.govWhat causes most cases of food poisoning in humans?
