Personal Responsibility in Food Consumption Act
The 2005 American Personal Responsibility in Food Consumption Act (H.R. 554), also known as the Cheeseburger Bill, sought to protect producers and retailers of foods—such as McDonald's from an increasing number of suits and class action suits by obese consumers. The Act stated that food-producing or retailing corporations cannot be legally held responsible for obesity, heart disease, or other health-related issues caused by consumption of their food, save for situations where actual food quality or handling was held responsible for such issues.
