This session will summarize recent North American and international outbreaks of hepatitis A virus (HAV) associated with imported frozen berries and challenges for agencies that have investigated and responded to the outbreaks. A second speaker will describe the investigation of a Salmonella I 4,[5],12:I outbreak linked to rotisserie pork and chicken and the contributing factors that were identified. The recent Listeria outbreak involving frozen raw vegetables has generated policy challenges for improved outbreak detection and response from foods that have not historically been implicated in outbreaks. A speaker will describe the challenges and actions that have been taken. Additionally, this session will provide a platform for a brief summary of two other recent outbreak investigations:  one speaker will describe the investigation of E. coli O157 outbreak in soy nut butter and another speaker will describe the investigation of Listeria monocytogenes in soft cheese. Both speakers will touch on the collaboration between federal, state, and local health agencies and actions taken to protect public health, as well as highlight investigational findings at the manufacturing firms that may have led to contamination of product.
