WASHINGTON - An analysis of more than 33,000 cases of foodborne illness shows that ground beef and chicken have caused more hospitalizations than other meats.

The report by the Center for Science in Public Interest says chicken nuggets, ham and sausage pose the lowest risk of foodborne illness.

The group used government data on 1,700 incidents over 12 years to analyze outbreaks of salmonella, E. coli, listeria and other pathogens that were definitively linked to a certain meat.

To calculate which meats were riskiest, CSPI ranked the foods in which contamination was most likely to cause hospitalizations. Some meats may have had more illnesses but were less likely to cause severe illness.
