Outbreak of E. coli O157:H7 Infections Associated with Beef from National Steak and Poultry Updated January 6, 2010

CDC is collaborating with public health officials in several states and the United States Department of Agriculture’s Food Safety and Inspection Service (FSIS) to investigate a multistate outbreak of human infections due to Escherichia coli O157:H7 (E. coli 0157:H7).

As of 5:00 PM EDT, Monday, January 4, 2010, 21 persons infected with the outbreak strain of E. coli O157:H7 had been reported from 16 states. The number of ill persons who were identified resides in each state as follows: CA (1), CO (1), FL (1), HI (1), IA (1), IN (1), KS (1), MI (1), MN (3), NV (1), OH (2), OK (1), SD (2), TN (1), UT (2), and WA (1).

Known illness onset dates range from October 3, 2009 through December 14, 2009. Most patients became ill between mid-October and late November. Patients range in age from 14 to 87 years and the median age of patients is 34 years, which means half are younger than 34 years. Forty-three percent of patients are females. There have been 9 reported hospitalizations, 1 case of hemolytic uremic syndrome (HUS), and no deaths.

The outbreak can be visually described with a chart showing the number of persons who became ill each day. This chart is called an epidemic curve or epi curve. Illnesses that occurred after December 22, 2009 might not yet be reported due to the time it takes between when a person becomes ill and when the illness is reported. This takes an average of 2 to 3 weeks. Please see the Timeline for Reporting of E. coli Cases for more details.

In early December 2009, CDC's PulseNet staff identified a multistate cluster of 14 E. coli O157:H7 isolates with a particular DNA fingerprint or pulsed-field gel electrophoresis (PFGE) pattern reported from 13 states. CDC's OutbreakNet team began working with state and local partners to gather epidemiologic information about persons in the cluster to determine if any of the ill individuals had been exposed to the same food source(s). Health officials in several states who were investigating reports of E. coli O157:H7 illnesses in this cluster found that most ill persons had consumed beef, many in restaurants. CDC is continuing to collaborate with state and local health departments in an attempt to gather additional epidemiologic information and share this information with FSIS. At this time, at least some of the illnesses appear to be associated with products subject to a recent FSIS recall.

On December 24, 2009, FSIS issued a notice about a recall of 248,000 pounds of beef products from National Steak and Poultry that may be contaminated with E. coli O157:H7. The recall was issued after FSIS determined there was an association between non-intact steaks (blade tenderized prior to further processing) and illnesses in Colorado, Iowa, Kansas, Michigan, South Dakota and Washington.

There needs to be some follow up on why HACCP is still be used. All inspectors will state that this HACCP program should be scrapped. But just like the congress and senate, they don't listen to the american public. Inspectors need to be allowed to inspect and not just audit paperwork. YOU DO NOT EAT PAPERWORK!! I could have kept working for the USDA. But decided to retire after 30 years, instead of watching the good inspection system we had go to the CRAPPER using HACCP!!
