Pandemic Vibrio parahaemolyticus, Maryland, USA, August 2012, J. Haendiges et al.
When you think of a pandemic, you don’t first think of foodborne illnesses.
However, a pandemic strain of bacteria that causes foodborne illness, Vibrio
parahaemolyticus, has been emerging worldwide; these bacteria usually
infect people who eat contaminated raw oysters. This strain is not commonly
found in the United States, but in 2012 it caused an outbreak in Maryland. The
affected patients had not eaten oysters, leaving cross-contamination during
food preparation as a possible source of their illness. The presence of this
dangerous strain in Maryland calls for public health measures to improve its
tracking and shorten response times when it is found.
