Officials with the St. Louis County Health Department say they learned
on Wed 9 Nov 2011 that 4 students contracted _E. coli_ in the
Northwest School District in Jefferson County in October 2011. One of
the students became so sick, he was placed on dialysis. Teachers and
staff at the school were notified, but no one knows how it happened.

Overall, since the outbreak was announced, 31 cases in the St. Louis
region have been confirmed, and 2 more cases are suspected. 6 of those
cases are in Jefferson County, but are not necessarily linked to the
St. Louis County outbreak. The source of each outbreak is still a
mystery. 2/3s of those infected say they ate at Schnucks' salad bars,
but Schnucks has not been identified as a source of the outbreak.

Health officials do say that they are not seeing many new suspected
cases to investigate, which could indicate that the source of the
bacterium has gone.

[The number of cases of enterohemorrhagic _E. coli_ in the St. Louis
area appears to be leveling off, suggesting that the vehicle is no
longer available. An epidemiological analysis led investigators to
suspect the salad bar of the large supermarket chain but no "smoking"
salad (genetically matched isolates from the food itself) was found.
This does not necessarily remove the salad bar as a vehicle but means
that the food vehicle that was contaminated was already gone by the
time of testing since fresh produce in salad bar has a short "salad"
life. - Mod.LL ]
