Forty-one people in 10 states have been infected with Salmonella Stanley after consuming imported dried wood ear mushrooms, according to a report just released by the US Centers for Disease Control and Prevention (CDC).
Four of the victims have been admitted to hospital.
Wood ear mushrooms are dried mushrooms, also commonly labelled or referred to as Kikurage, Dried Black Fungus, Dried Fungus, or Mu’er/Mu Er/Mu-Err, according to the Outbreak Investigation notice posted by the US Food and Drug Administration (FDA).
Illnesses have been reported in Arizona (1), California (25), Connecticut (1), Georgia (1), Illinois (5), Louisiana (1), New Jersey (2), New York City (1), Pennsylvania (2), and Wisconsin (2).
As of now, there have been no illnesses reported in Canada.
The mushrooms implicated in this outbreak were imported by Wismettac Asian Foods, Inc. of Santa Fe Springs, CA and sold to restaurants in 32 states and at least 3 Canadian provinces. The California Department of Public Health (CDPH) has released a list of restaurants that were supplied with the suspect mushrooms.
CDPH has recovered Salmonella from a sample of the mushrooms obtained from one of the restaurants where outbreak victims from that state reported eating. The genetic sequence of the Salmonella is being analyzed in order to determine whether it is a match for the outbreak strain recovered from patients.
Wismettac Asian Foods has already initiated a recall of the implicated mushrooms in both the US and Canada.
