    Shiga toxin-producing E. coli (STEC) was first identified in the 
early 1980s in North America as the cause of outbreaks of bloody 
diarrhea, often leading to severe and fatal illness. These outbreaks 
were associated with ground beef consumption, and E. coli O157:H7 was 
the STEC identified as causing the illnesses. In 1994, FSIS notified 
the public that raw ground beef contaminated with E. coli O157:H7 is 
adulterated under the FMIA unless the ground beef is processed to 
destroy this pathogen. Also in 1994, FSIS began sampling and testing 
ground beef for E. coli O157:H7.
    On January 19, 1999, FSIS published a policy statement in the 
Federal Register that explained that if non-intact raw beef products or 
intact raw beef products that are to be processed into non-intact 
product prior to distribution for consumption are found to be 
contaminated with E. coli O157:H7, they will be deemed to be 
adulterated if not processed to destroy the pathogen (64 FR 2803).
    Shiga toxins are produced by other E. coli serotypes in addition to 
E. coli O157:H7. While many STEC strains have been found in ruminant 
feces, not all of these STECs are pathogenic. The scientific community 
believes that the STECs that are pathogenic not only contain the Shiga 
toxin but also additional virulence determinants that, together with 
the toxin, cause illnesses similar to those caused by E. coli O157:H7. 
The subset of STECs that contain both the toxin and these additional 
virulence determinants, including E. coli O157:H7, is known as 
enterohemorrhagic E. coli (EHEC).
    In the United States, there is growing awareness that STECs other 
than E. coli O157:H7 (non-O157:H7 STECs) cause sporadic and outbreak-
associated illnesses. This awareness is attributable in part to the 
increasing availability of laboratory reagents that can be used to 
diagnose illnesses and to detect strains of STECs in food and other

[[Page 57286]]

environmental samples. The number of non-O157:H7 STEC infections 
reported to the CDC from 2000 to 2005 increased from 171 to 501 cases, 
suggesting a higher burden of illness than previously thought.
    Outbreaks associated with non-O157:H7 STECs have been reported 
worldwide, including thirteen in the United States from 1990 to 2006. 
The 2006 data is still preliminary. Many outbreaks were attributed to 
consumption of fresh produce; none were attributed to ground beef 
consumption. However, in 2006, non-O157:H7 STEC illness was diagnosed 
in a patient in New York who had consumed ground beef shortly before 
illness onset. The same STEC strain, indistinguishable by pulsed field 
gel electrophoresis, was detected in the patient's stool and in 
leftover ground beef that the patient had consumed. In this case, FSIS 
was unable to take further action because the product could not be 
definitively traced to a production lot.
    FSIS, FDA CFSAN, and CDC will hold a public meeting on October 17, 
2007, to solicit input from industry, consumers, academia, and other 
public health and regulatory agencies on the issue of whether non-
O157:H7 STECs should also be considered to be adulterants. This meeting 
will rely on relevant data in addressing the most important questions 
that underlie this issue, including:
     What is the epidemiology of non-O157:H7 STEC illness?
     What can be done to enhance the surveillance and reporting 
of non-O157:H7 STEC illnesses?
     What is the prevalence of non-O157:H7 STEC in livestock 
and in finished product? Are species other than cattle, such as sheep, 
goats, and swine, important sources of non-O157:H7 STECs?
     What are the best methods for detecting pathogenic non-
O157:H7 STECs in food? What are the most relevant markers for 
pathogenic STECs?
     Are interventions designed to remove or destroy E. coli 
O157:H7 in foods or raw products effective against non-O157:H7 STECs as 
     How should regulatory agencies define, monitor, and 
control pathogenic non-O157:H7 STECs in food or raw products?
    All interested parties are welcome to attend the meeting and to 
submit written comments and suggestions through October 15, 2007 to Dr. 
Eblen by phone (202) 690-6238, fax (202) 690-6334, e-mail:

Agriculture, Food Safety and Inspection Service, Office of Public 
Health Science, 1400 Independence Avenue, SW., 357 Aerospace Center, 
Washington, DC 20250-3766. Individuals who do not wish FSIS to post 
their personal contact information--mailing address, e-mail address, 
telephone number--on the Internet may leave the information off their
