In late April 2008, San Diego County health officials announced that a number of Hepatitis A (HAV) infections had been traced to a Chipotle Grill restaurant in La Mesa, California, near San Diego. Officials advised customers who had eaten at the restaurant between March 1 and April 22 that they might be at risk for infection. As of early May, more than twenty people who ate at the La Mesa restaurant have tested positive for HAV infection. Several of those victims contacted Marler Clark for assistance with their cases.  All claims have been settled.

Hepatitis A is a food borne virus that can be passed by infected food handlers to consumers. The virus attacks the liver, and symptoms can include nausea, vomiting, abdominal cramps, dark urine, fever, chills, fatigue, body aches, loss of appetite, and later on, jaundice. In extreme cases, liver failure can result. The virus has a long incubation period, and symptoms may not appear for fifteen to fifty days.
