Several state health departments, CDC, and the United States
Department of Agriculture's Food Safety and Inspection Service are
investigating a multi-state outbreak of Escherichia coli O157:H7
infections. On January 29, USDA issued a notice about a recall of 21.7
millions pounds of frozen ground beef patties.

Health officials in several states who were investigating reports of
E. coli O157 illnesses found that many ill persons had consumed the
same brand of frozen ground beef patties. Ground beef patties
recovered from MCDONALD'S fastfood outlets were tested by state public
health department and federal laboratories. Tests conducted by the New
York State Wadsworth Center Laboratory on opened and unopened packages
of frozen ground beef patties yielded E. coli O157 isolates with
several different "DNA fingerprint" patterns.

Ill persons reside in 8 states [Connecticut (2), Florida (1), Indiana
(1), Maine (1), New Jersey (9), New York (13), Ohio (1), and
Pennsylvania (12)]. Thirty-three (89%) of 37 patients with a detailed
food history consumed ground beef. Seven fatalities have confirmed
associations with recalled products because the strain isolated from
the person was also isolated from the meat in MCDONALD'S outlets. The
first reported illness began on January 5, 2008, and the last began on
January 22, 2008. Among thirty-three ill persons for whom
hospitalization status is known, twenty-one (64%) were hospitalized.
Two patients developed a type of kidney failure called hemolytic-
uremic syndrome (HUS). No deaths have been reported. Eighteen (45%)
patients are female. The ages of patients range from 1 to 77 years;
50% are between 15 and 24 years old (only 14% of the US population is
in this age group).

Consumers who have questions about the recalled products can contact
USDA-FSIS at "Ask Karen'" online at www.AskKaren.gov or call the Meat
and Poultry Hotline at 1-800-244-6227. Because any raw ground beef can
contain disease-causing germs, CDC and USDA-FSIS encourage consumers
to use good food safety practices and to heed the following advice:

Using a food thermometer is the only sure way of knowing if your food
has reached a high enough temperature to destroy bacteria.
Ground beef products should be cooked to an internal temperature of
160 degrees Fahrenheit. Color is not a reliable indicator that ground
beef patties have been cooked to a temperature high enough to kill
harmful bacteria such as E. coli O157:H7. For more information go to

To keep your food safe, remember to Clean, Separate, Cook, and Chill.
