(Reuters) – A total of 156 people in 10 states have been infected with E. coli after eating tainted ground beef at home and in restaurants since the beginning of March, the U.S. Centers for Disease Control and Prevention (CDC) said on Tuesday.
No deaths have been reported but 20 people have been hospitalized after they were infected with the strain E. coli O103 since March 1, the CDC said on its website.
The agency said an investigation is ongoing to determine the source of the contaminated ground beef that was supplied to grocery stores and restaurants.
“At this time, no common supplier, distributor, or brand of ground beef has been identified,” the CDC said.
The investigation began on March 28, when officials in Kentucky and Georgia notified the CDC of the outbreak. Since then, some 65 cases have been reported in Kentucky, 41 in Tennessee and another 33 in Georgia.
E. coli cases have also been reported in Florida, Illinois, Indiana, Minnesota, Mississippi, Ohio and Virginia.
The CDC said that illnesses after March 26 may not have been reported yet because the lead time is two to three weeks.
People infected with the bacteria get sick two to eight days after swallowing the germ, and may sometimes develop a type of kidney failure.
Many of the infected people had bought large trays or chubs of ground beef from grocery stores and used the meat to make dishes like spaghetti sauce and Sloppy Joes, the agency said.
The regulator said it is not recommending that consumers avoid eating ground beef at this time, but said that consumers and restaurants should handle ground beef safely and cook it thoroughly to avoid foodborne illnesses.
