Salmonella infections have not decreased during the past 15 years in the US and have instead increased by 10%, according to “Vital Signs,” a report issued by the Centers for Disease Control and Prevention (CDC). During the same period, the report noted, illnesses caused by pathogens such as E. coli O157 have declined nearly 50% and the overall rates of six food-borne infections have been reduced by 23%.In 2010, FoodNet sites, which include about 15% of the American population, reported nearly 20,000 illnesses, 4,200 hospitalizations and 68 deaths from nine food-borne infections. Of those, Salmonella caused more than 8,200 infections, nearly 2,300 hospitalizations and 29 deaths (54% of the total hospitalizations and 43% of the total deaths reported through FoodNet). The C.D.C. estimated there are 29 infections for every lab-confirmed Salmonella infection.
The rate of E. coli O157 cases reported by FoodNet sites was 2 cases per 100,000 people in 1997 and, by 2010, had decreased to 0.9 cases per 100,000 people. The nearly 50% reduction in E. coli O157 incidence is considered significant when compared to the lack of change in Salmonella incidence.
