  • Presentation Content Why do we care about foodborne outbreaks? What partners need to be involved and why? How does this partnership work during an outbreak? What are some common conflicts between partners? Are there resources for partners? Q & A
  • Slide 3
  • Why do we care about foodborne outbreaks?
  • Slide 4
  • Potential illness reaching the masses Intentional vs accidental contamination Possible wide distribution of a contaminated item Vulnerable populations Loss of days worked, wages, business, trust

  • One example When has this worked?
  • Slide 22
  • Real Life Event: Salmonella
  • Slide 23
  • Monday, May 13, 2013 Day 1
  • Slide 24
  • Fifteen ill with N/V/D (some bloody) 10 / 15 hotel staff (3/10 food handlers) 1 hospitalized Two of three samples (+ Salmonella) May 8 th was the first onset 4pm - Conference call Local Health Dept: Epi, Env Hlth State: Epi, Env Hlth, Lab, Public Affairs 10:00am Call from CD Nurse
  • Slide 25
  • Day 1 Summary of Actions/Decisions Confirm the story Implement control measures with hotel/rest. Interview ill Coordinate hotel assessment with Env Hlth Coordinate stool specimen collection, shipment, and testing with state lab Develop communication tools Send statewide & national alerts to identify additional cases Request receipts from hotel (case-control study) Develop survey from hotel menu Send state staff to Cumberland to assist with summarizing data and data entry
  • Slide 26
  • 3 Partners with 1 Goal Food & Lodging Outbreak Laboratory Test stool samples Environmental Health Assess facilities Epidemiology Coordinate activities Interview patients Characterize ill Stop the Outbreak
  • Slide 27
  • Activities of partners Test stool Grow isolate Biochem tests Subtyping PFGE Environmental testing (partner labs) Coordinate activities Characterize illness Analyze data from all partners LaboratoryEpidemiology Facility Assessment Processes Employees Environmental Health
  • Slide 28
  • Results Laboratory Environmental Health Epidemiology
  • Slide 29
  • Laboratory Results 54 specimens tested 2 (4%) unsatisfactory 27 (50%) negative 25 (46%) positive 25 (100%) Salmonella typhimurium 25 (100%) had the same matching PFGE pattern
  • Slide 30
  • Environmental Health Results Environmental Assessments Risk Factors Personal Hygiene Approved Source Contamination Holding Cooking Interviews Trainings
  • Slide 31
  • Environmental Health Actions Required reportable BIG 5 Tools Three legged stool Employee Health Hand washing No Bare Hand Contact of Ready to Eat food Risk Control Plans Enforcement

  • Epidemiology Results Total Ill 100 Hospitalized 8 Counties Represented 11 Ages 17yrs-81yrs Median: 45 yrs Exposure Relative Risk FOOD Employee Potluck0.62 Caf Breakfast Buffet0.89 Caf Lunch Buffet1.09 All American Grill 3.6 WORK TASK All American Grill Supervisor 4.3 RESULTS Those who ate/drank at the All American Grill were 3.6 times more likely to become ill when compared to those who did not eat/drink at the All American Grill
  • Slide 36
  • Process Results After outbreaks are over the following questions are asked of those involved: What worked well during this outbreak? What did not work well during this outbreak? What recommendations do you have to improve the handling of future outbreaks?
  • Slide 37
  • What are some common conflicts between partners?
  • Slide 38
  • Potential conflicts with partners Not aware of numerous incoming specimens Specimens may be un- satisfactory Interest in accompanying EH during facility assessments Timing of lab results can feel delayed LaboratoryEpidemiology Expanded workload Additional team members on site Environmental Health
  • Slide 39
  • Potential conflicts with partners Feels like state is taking over instead of assisting Nursing staff pulled from clinic to address outbreak needs Ensure the county is happy with how the outbreak is lead Ensuring the same message is communicated to the public Local Health DeptState Health Dept
  • Slide 40
  • Conflict resolution Establish relationships with partners before or outside of an outbreak situation Who is your point of contact and what can they do for you Understand the role of each partner What do they do and why Do they have the resources the response requires Communication How often is everyone updated and through what method Take the opportunity to both learn from others and share your knowledge
  • Slide 41
  • Are there resources for partners?
