Hepatitis A spread by strawberries in margaritas

Strawberries at three El Paso County restaurants have been connected to a multi state hepatitis A outbreak... strawberries used in margaritas at the restaurants... may have been contaminated with the virus.
Health officials say anyone who ate or drank strawberries at the restaurants should receive hepatitis A vaccinations.
Health officials have connected more than 100 hepatitis A cases to frozen strawberries imported from Egypt since Jan. 1.

Everyone knows to wash commercially-purchased strawberries before eating them, but who would suspect strawberries in margaritas not having been washed.
And it's a strange world we live in where it's cheaper to import strawberries from Egypt than it is to grow them in this country.
