Confirmed / Presumptive Case Counts: 6 / 5Positive Samples (Food / Environmental / Water): 2 / 2 / 0
OUTBREAK SUMMARY:

At a time when ground beef was thought to be the source of all foodborne E. coli O157 infections, this was the first documentation of venison-associated E. coli O157:H7 outbreak. Epidemiologists showed that deer can be colonized by E. coli O157:H7 and ultimately be a source of human infections. … Continue Reading ››

Hospitalizations: 6Deaths: 2
OUTBREAK SUMMARY:

This investigation implicated a novel vehicle—strawberries—as the cause of an outbreak of E. coli O157 infections. An association with locally produced strawberries quickly became apparent as cases were interviewed; but the fact that almost all had purchased them at roadside stands and farmer’s markets led to concern about potential … Continue Reading ››

Milk Crates, Cartons, & Jugs

Outbreak: Milk Crates, Cartons, & Jugs 
Product: Milk Crates, Cartons, & JugsInvestigation Start Date: 01/27/2010

OUTBREAK SUMMARY:

This outbreak illustrates the value of descriptive epidemiology and the virtue of epidemiologist persistence! Over a 12-month period during 2009–2010, a total of 25 infections by Salmonella Braenderup with matching PFGE patterns were reported—no more than 4 in any given month. After 3 scattered cases over 3 months, the … Continue Reading ››

This outbreak focused FDA attention on the role spices may … Continue Reading ››

Bagged Spinach

Outbreak: Bagged Spinach

Contact with WI and NM showed cases already underway with spinach showing signs of being the culprit. Contact with Utah allowed them … Continue Reading ››

Cal-Farms Parsley

Outbreak: Cal-Farms Parsley

OUTBREAK SUMMARY:

This 2005 McGrath's Fish House outbreak of E. coli O157:H7 infections was traced back to parsley from Cal-Farms. The journey to finding the source was interesting: 206 people interviewed, 64 ill people, extremely muddy field conditions, cattle near the flooded parsley fields, and even evidence of heavy deer presence.
