"We are working closely with the U.S. Centers for Disease Control and Prevention and state and local agencies to determine the cause and scope of the problem,” Dr. Robert Brackett, a top official at the U.S. Food and Drug Administration (FDA), said in a release.
The FDA said the outbreak involves the E. coli strain O157:H7, the same strain that killed six people in Walkerton, Ont., in 2000. It has advised people not to eat bagged spinach, but not identified a particular brand.
There is no indication so far that E. coli has contaminated spinach in Canada, said René Cardinal, acting national manager for fresh fruits and vegetables at the Canadian Food Inspection Agency. The FDA will keep the Canadian agency informed of the progress of its investigation.
The main problem appears to be in Wisconsin, where one person has died and 20 are sick.
Other states affected include Connecticut, Idaho, Indiana, Michigan, New Mexico, Oregon and Utah.

or drinking sewage-contaminated water," the site says.
