Food poisoning cases are a type of personal injury lawsuit. Most commonly, they fall into the category of product liability cases, because it is a defective product that causes the injury. In order to determine who may be liable, it is best to consult a personal injury or product liability attorney that specializes in food poisoning cases. There are specific problems related to proving fault in food poisoning cases, such as establishing that it was the food from a specific establishment (restaurant, food service provider, etc) that caused the illness. An experienced lawyer can help navigate these difficulties.
