The CDC reports today that there are currently only 26 illnesses in 11 states that are linked to the Fairbank Farms E. coli O157:H7 ground beef outbreak and recall. This represents a reduction in the number of cases attributed to the outbreak by two.
Here is the outbreak rundown:
On October 31, 2009, FSIS issued a notice about a recall of over 500,000 pounds of beef products from Fairbank Farms that may be contaminated with E. coli O157:H7. Health officials in several states who were investigating a cluster of E. coli O157:H7 illnesses, with isolates that match by “DNA fingerprinting” analyses, found that most ill persons had consumed ground beef, with several purchasing the same or similar product from a common retail chain. At least some of the illnesses appear to be associated with products subject to these recalls. A sample from an opened package of ground beef recovered from a patient’s home was tested by the Massachusetts Department of Health and yielded an E. coli O157:H7 isolate that matched the patient isolates by DNA analysis.
The cluster includes 26 persons from 11 states infected with matching strains of E. coli O157:H7. The number of ill persons identified in each state is as follows: California (1), Connecticut (4), Massachusetts (8), Maryland (1), Maine (2), Minnesota (1), New Hampshire (4), New Jersey (1), New York (1), Pennsylvania (2), and Vermont (1). Of these, the genetic association of 13 human isolates and the product isolate have been confirmed by an advanced secondary DNA test; secondary tests are pending on others. Depending on the results of continuing laboratory testing and ongoing case finding, the number of persons determined to be in this cluster may increase or decrease.
