  • 205 cases in 26 states.Cattle are considered the primary reservoir of E. coli O157, but fecal shedding by other domestic livestock and wildlife has been described.The outbreak was amplified because the contaminated spinach from one or a few farms was mixed with spinach from numerous other farms, then bagged by a few processors, marketed under several brands, and distributed nationally and internationally.

  • CEIP is alerted when any foodborne outbreak is identified. They help to coordinate foodborne outbreak response in Bay Area counties (Alameda, Contra Costa, San Francisco) alongside CDPH
  • The time from when a patient eats contaminated food to the when the public health lab completes confirmatory testing and fingerprintinghttp://www.cdc.gov/ecoli/reportingtimeline.htm A series of events occurs between the time a patient is infected and the time public health officials can determine that the patient is part of an outbreak. This means that there will be a delay between when a person gets sick and confirmation that he or she is part of an outbreak. Public health officials work hard to speed up the process as much as possible. The timeline is as follows:Incubation time: The time from eating the contaminated food to the beginning of symptoms. For E. coli O157, this is typically 3-4 days.Time to sample collection: The time from the first symptom until the person seeks medical care, when a diarrhea sample is collected for laboratory testing. This is typically 1-5 days.Time to diagnosis: The time from when a person gives a stool sample to when E. coli O157 is obtained from it in a laboratory. This may be 1-3 days from the time the sample is received in the laboratory. The diagnosis of E. coli infection may be reported to the local health department at this time.E. coli isolate shipping time: The time required to ship the E. coli O157 bacteria from the laboratory to the state public health authorities that will perform “DNA fingerprinting.” This may take 0-7 days depending on transportation arrangements within a state and the distance between the clinical laboratory and public health department.Time to serotyping and “DNA fingerprinting”: The time required for the state public health authorities to perform “DNA fingerprinting” on the E. coli O157 isolate and compare it with the pattern of the outbreak strain. Ideally, this can be accomplished in 1 day. However, many public health laboratories have limited staff and space, and experience multiple emergencies at the same time. Thus, the process may take 1-4 days.The time from the beginning of a person’s illness to the confirmation that he or she was part of an outbreak is typically about 2-3 weeks

    15. 15. SHIGA TOXIN PRODUCING E. COLI 15
    16. 16. E. COLI O157:H7  First recognized as pathogen in 1982  First outbreak traced to hamburgers  USDA banned sale of raw meat containing E. coli O157:H7 in 1994  Many outbreaks now linked to contaminated raw vegetables (e.g., sprouts, leafy greens) and other contaminated ready to eat foods 16
    17. 17. STEC OUTBREAKS 2012 Multistate Outbreak of Shiga Toxin-producing Escherichia coli O157:H7 Infections Linked to Organic Spinach and Spring Mix Blend Multistate Outbreak of Shiga Toxin-producing Escherichia coli O145 Infections Source not identified Multistate Outbreak of Shiga toxin-producing Escherichia coli O26 Infections Linked to Raw Clover Sprouts at Jimmy John's Restaurants 17
    18. 18. STEC OUTBREAKS 2011 Multistate Outbreak of E. coli O157:H7 Infections Linked to Romaine Lettuce Outbreak of Shiga toxin-producing E. coli O104 (STEC O104:H4) Infections Associated with Travel to Germany (and consumption of raw sprouts) Multistate Outbreak of E. coli O157:H7 Infections Associated with Lebanon Bologna Multistate Outbreak of E. coli O157:H7 Infections Associated with In-shell Hazelnuts 18
    19. 19. E. COLI CONTAMINATION AN EXAMPLE  Multistate E. coli O157:H7 outbreak linked to baby spinach in 2006 (205 cases, 102 hospitalizations, 3 deaths)  Outbreak strain isolated from both cattle and feral swine feces near spinach field  Spinach from 1 field with E. coli contamination mixed with spinach and lettuce from other farms at central processing plants 19

    21. 21. E. COLI AND MEDICAL SURGE AN EXAMPLE  Outbreak of E. coli O104:H4 in 2011 – 3,816 cases in Germany; 54 deaths – 845 (22%) involved Hemolytic Uremic Syndrome (HUS)  Hospitals in most affected areas of Germany experienced large influx of patients with HUS and other complications due to E. coli infection – Doubled number of staff – Tripled machines for dialysis and plasma exchange 21
    22. 22. E. COLI AND MEDICAL SURGE AN EXAMPLE Video news clip: http://www.bbc.co.uk/news/world-13696131 22
    23. 23. SHIGA TOXIN PRODUCING E. COLI  Common reservoirs = cattle and other ruminants  Vehicles in past outbreaks = ground beef, petting zoos, raw vegetables and fruit, unpasteurized apple cider, water, etc.  Growth requirements = facultative anaerobe, nonsporulating bacterium 23
    24. 24. E. COLI - EPIDEMIOLOGY  Mode of Transmission  Ingestion of food contaminated by traces of feces or direct contact with animals and their environment  Incubation Period  Range from 2-10 days after exposure; median 3-4 days  Period of Communicability  When the bacteria is being excreted  1 week or less (adults) or up to 3 weeks (children) 24 24
    25. 25. SHIGA TOXIN PRODUCING E. COLI (STEC)  Some E. coli bacteria produce shiga toxin  When shiga toxin enters the bloodstream it can damage the red blood cells  Severity of illness ranges from mild diarrhea to life threatening HUS 25 25
    26. 26. CLINICAL SYMPTOMS AND TREATMENT OF STEC INFECTIONS Dr. Karen Smith Health Officer Napa County Public Health 26
    27. 27. SYMPTOMS Symptoms of E. coli infection:  Watery and often bloody diarrhea  Abdominal cramping  Abdominal pain  Little or no fever Most people will recover within 5 to 10 days 27
    28. 28. HEMOLYTIC UREMIC SYNDROME (HUS)  Life threatening condition that often requires ICU treatment  Triad of hemolytic anemia, thrombocytopenia, and acute renal failure  Often requires blood transfusions and dialysis during acute phase 28
    29. 29. HEMOLYTIC UREMIC SYNDROME (HUS)  On average, HUS occurs in ~6% of E. coli patients  Case fatality rate of 3-5%  Most cases of HUS occur in children under 5  Use of antibiotics and anti-diarrheal medication to treat E. coli infection increases risk of HUS 29
    30. 30. DIALYSIS  Average length of dialysis for patients with HUS due to E. coli infection is 5-7 days (but can vary widely)  Peritoneal dialysis widely used for pediatric patients  Hemodialysis also suitable for children - may be preferable in patients with severe abdominal pain 30
    31. 31. MANAGEMENT OF HUS Successful management of HUS includes: • Fluid therapy • Management of acute renal failure - ~50% of HUS patients require dialysis • Blood and/or plasma transfusion - Most children require packed RBC transfusion • Management of hypertension • Nutritional support and pain management 31
    32. 32. STEC – SPECIAL CONSIDERATIONS  Most E. coli related HUS cases seen in children < 5, but elderly and immunocompromised are also at increased risk for HUS  Elderly patients at higher risk for E. coli blood stream infection (bacteremia) and may develop additional complications due to presence of other illnesses 32
    33. 33. FOODBORNE OUTBREAK RESPONSE Dr. Jennifer Henn Epidemiologist Napa County Public Health 33
    34. 34. OUTBREAK INVESTIGATION GOALS  Identify all cases  Find a common exposure  Determine cause  Stop the exposure  Prevent future cases  Notify providers  Inform the public 34 34

    50. 50. Scenario On November 18, 2013, healthcare providers at community health centers, private physician’s offices and local emergency departments began seeing previously healthy patients with complaints of abdominal pain throughout Napa County. 50
    51. 51. Scenario (Continued) Within one day, 40 cases of bloody diarrhea had been reported by 10 healthcare providers at community health centers, private physician’s offices and local emergency departments in the county. Two days after the first reports of abdominal pain and bloody diarrhea, 4 patients (of which, 2 are pediatric) were admitted to the Intensive Care Unit with symptoms of decreased urine output, lethargy and persistent bloody diarrhea. These patients were diagnosed with hemolytic uremic syndrome. Cases presenting similar symptoms continue to be reported throughout the county. 51
    52. 52. Scenario (Continued) Five days after the first reported case, 225 patients (approximately 10% with HUS) have been identified with similar presenting symptoms at local hospitals, community health centers and private physician practices. 52
    53. 53. Scenario (Continued) Healthcare facility staff has requested guidance from the local Public Health Laboratory on appropriate protocols for specimen collection and laboratory techniques to confirm the diagnosis. Healthcare facilities are requesting guidance on necessary levels of isolation and personal protective equipment requirements for staff. 53
