Prevalence and Incidence of Food poisoning

About prevalence and incidence statistics: The term 'prevalence' of Food poisoning usually refers to the estimated population of people who are managing Food poisoning at any given time. The term 'incidence' of Food poisoning refers to the annual diagnosis rate, or the number of new cases of Food poisoning diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.

Incidence (annual) of Food poisoning: about 76 million cases annually in USA (NIDDK)
Incidence Rate: approx 1 in 3 or 27.94% or 76 million people in USA [about data]
Prevalance of Food poisoning: Although most foodborne infections are undiagnosed and unreported, the Centers for Disease Control and Prevention estimates that every year about 76 million people in the United States become ill from pathogens in food. Of these, up to 5,000 die. 1 ... An estimated 76 million cases of foodborne disease occur each year in the United States.2 ...

Prevelance of Food poisoning discussion: An estimated 76 million cases of foodborne disease occur each year in the United States. The great majority of these cases are mild and cause symptoms for only a day or two.  Some cases are more serious, and CDC estimates that there are 325,000 hospitalizations and 5,000 deaths related to foodborne diseases each year.  The most severe cases tend to occur in the very old, the very young, those who have an illness already that reduces their immune system function, and in healthy people exposed to a very high dose of an organism.  2
