  1. The role of heightened surveillance in an outbreak of Escherichia coli O157. H7.

    Article - En anglais

    After instituting laboratory screening for Escherichia coli O157.

    H7, a Connecticut hospital isolated the organism from four persons in September 1993.

    As a result, an outbreak of E. coli O157.

    H7 associated with a country club was detected.

    The club had served hamburger from the same shipment at two picnics.

    Attendees of two picnics were interviewed, stool cultures were obtained from symptomatic persons, and the remaining hamburger was cultured.

    Twenty (22%) of 89 persons who ate hamburger became ill, compared with 1 of 60 who did not eat hamburger (relative risk=13.5. 95% confidence interval 3.2-56.3).

    Among persons who ate hamburgers, illness was strongly associated with eating hamburger that was not thoroughly cooked (P<0001).

    All 20 samples from 5 remaining boxes of patties yielded E. coli O157.

    H7. Isolates from hamburger and case-patients were indistinguishable by pulsed-field gel electrophoresis.

    Heightened surveillance can rapidly identify outbreaks and may mitigate their impact.

    However, continued review of food safety issues is necessary if E. coli O157.

    H7 outbreaks are to be prevented.
