On January 19, 2007, a food worker at Houlihan’s restaurant in Geneva, Illinois, was diagnosed with a hepatitis A infection. Kane County health officials inspected the restaurant that afternoon, and warned all patrons who had eaten at the restaurant between January 8 and January 19, when the employee was infectious, of their potential exposure to the hepatitis A virus. In particular, customers who had ordered and consumed iced drinks were at risk for becoming ill with hepatitis A.
The Kane County Health Department planned clinics at two locations in Aurora, Illinois, between January 21, 2007 and February 2, 2007 so that patrons who had been exposed to the hepatitis A virus at Houlihan’s could receive free injections of Immune globulin, which can prevent, or lessen the effects of, hepatitis A infection.
Marler Clark filed a hepatitis A class action lawsuit against Houlihan's on January 26, 2007. The matter was resolved in 2008.
