A study that collected data from three surveillance networks showed that foodborne illness may be responsible for about 14% of all norovirus outbreaks worldwide. Researchers said noroviruses are a main cause of gastroenteritis, and the study found worldwide similarity in the proportion of norovirus outbreaks linked to foodborne transmission.
Researchers at the CDC reviewed data on foodborne illness from 1998 to 2008 and found that fish, poultry and beef accounted for the largest share of outbreaks, with fish and poultry responsible for 17% each of illnesses tied to food, and beef responsible for 14%. The study also found that the share of these illnesses tied to eggs has decreased, from 6% in 1998-1999 to 2% in 2006-2008, because of declining cases of salmonella. Leafy greens and dairy products were responsible for a rising share of incidents.
Scientists found that children who recovered from severe foodborne illnesses -- including E. coli and salmonella infection -- may experience health problems, including high blood pressure or kidney damage, 10 to 20 years later. Consumer advocacy group Safe Tables Our Priority has launched the first national registry of food-poisoning survivors with long-term health concerns to encourage research on foodborne illnesses.
Eating five servings of fruits and vegetables each day, exercising often, drinking moderately and quitting smoking increases a person's lifespan by an average of 14 years, according to a new study. Researchers say the findings support the idea that small lifestyle changes can make a big impact on one's overall health.
