From the article:
Robert Tauxe, deputy director of the Division of Foodborne, Bacterial and Mycotic Diseases at the Centers for Disease Control and Prevention, said Aug. 28 that the number of illnesses being reported has dropped to a level that public health officials would expect to see in the absence of an outbreak.
Tauxe said that clusters of illnesses, created when multiple people fell ill after eating at the same restaurants, have not occurred since early July.
This is reassuring news.
