Truffles cheeses made by Wisconsin’s Crave Brothers
Farmstead Cheese Company are the likely source
Five people in four states, including one who died,
being infected with the same strain of Listeria
monocytogenes has the federal Centers for Disease Control and Prevention
(CDC) worrying about potentially contaminated cheeses that were distributed
nationwide.
According to the CDC, the ongoing investigation
indicates that Les Frères, Petit Frère, and Petit Frère with Truffles cheeses
made by Wisconsin’s Crave Brothers Farmstead Cheese Company are the likely
source of the deadly outbreak. On July 3 Illinois, Indiana and Ohio each have
reported one case associated to the outbreak strain. Two cases were confirmed
in Minnesota, including the death case. One illness in a pregnant woman
resulted in a miscarriage.
The Listeria outbreak is the subject of a continuing
and collaborative investigation is involving local and state health agencies
along with the U.S. Food and Drug Administration (FDA), and the Atlanta-based
CDC. According to CDC the warning is especially important for pregnant women,
older adults, and persons with weakened immune systems, who are at the highest
risk for infection and serious outcomes.
Crave Brothers, based in Waterloo; WS distributed
their cheese products through retail and food service outlets. The company also
fulfilled customer orders by mail order. Consumers who purchased any of the
recalled cheeses should not eat them and should throw away any remaining
cheeses, according to CDC. It said the warning is especially important for
pregnant women, older adults, and persons with weakened immune systems, who are
at the highest risk for infection and serious outcomes.
Listeria is
feared for its relatively high fatality rate, especially among those
populations CDC is warning during the current outbreak. Listeria outbreaks
involving ready-to-eat meats in Canada and cantaloupe in the U.S. ended with
deaths of 30-40 percent of those infected.
In the current investigation, CDC says public health
investigators are using DNA “fingerprints” of Listeria obtained through testing with pulsed-field gel
electrophoresis, or PFGE, to identify cases of illness that may be part of this
outbreak.
Laboratory tests conducted by the Minnesota Department
of Agriculture on samples of Les Frères and Petit Frère with Truffles cheeses
made by Crave Brothers from two retail stores confirmed the presence of the
outbreak strain of Listeria monocytogenes.
Further testing and confirmation of the results are pending.
