Subway Hepatitis A Outbreak
In mid-October, 1999, health officials in King and Snohomish counties became aware of a hepatitis A outbreak. By November 5, 1999, the outbreak was traced to two Subway Sandwich outlets.
It is estimated that over 40 persons became ill as a result of eating contaminated food sold at the two Subway outlets implicated in the September 1999 hepatitis A outbreak.
