OUTBREAK OF CHOLERA ASSOCIATED WITH CRAB BROUGHT FROM AN AREA WITH EPIDEMIC DISEASE

From 31 March through 3 April 1991, 8 New Jersey residents developed severe, watery diarrhea after eating crabmeat brought back in the suitcase of a traveler to Ecuador. Stool cultures yielded toxigenic Vibrio cholerae O1, serotype Inaba, biotype El Tor from 4 persons, and vibriocidal antibody titers were greater-than-or-equal-to 1:640 in 7 persons, indicating recent infection with Vibrio cholerae O1. Eating crab was statistically associated with illness (P = .006); however, no leftover crabmeat was available for testing. All 8 patients fully recovered and no cases of secondary transmission were reported. This was the first reported incident of cholera in the continental United States associated with food transported from an area with epidemic disease. Discouraging the transport of perishable souvenir seafood may prevent further outbreaks.
