    Article - En anglais

    A protracted outbreak of Escherichia coil O157 : H7 infections was caused by consumption of unpasteurized ( « raw ») milk sold at Oregon grocery stores.

    Although it never caused a noticeable increase in reported infections, the outbreak was recognized because of routine follow-up interviews.

    Six of 16 Portland-area cases reported between December 1992 and April 1993 involved people who drank raw milk from dairy A. By pulsed-field gel electrophoresis (PFGE), E. coli O157 : H7 isolates from these cases and from the dairy A herd were homologous (initially, 4 of 132 animals were E. coli O157 : H7-positive).

    Despite public warnings, new labeling requirements, and increased monitoring of dairy A, retail sales and dairy-associated infections continued until June 1994 (a total of 14 primary cases).

    Seven distinguishable PFGE patterns in 3 homology groups were identified among patient and dairy herd E. coli O157 : H7 isolates.

    Without restrictions on distribution, E.

    Coli O157 : H7 outbreaks caused by raw milk consumption can continue indefinitely, with infections occurring intermittently and unpredictably.
